3. EXPLOSION TRAINING – 2006 SAFETY FIRST COAL COMPANY MINE HISTORY AVERAGE WORKING HEIGHT – 48” VENTILATION SYSTEM – EXHAUSTING VENTILATION DIRECTION – AS SHOWN ON MAP FAN INFORMATION– 48” FAN, 250HP – 550 VAC MOTOR Seven (7) persons are scheduled to produce coal on the West Mains Section, located 2700 feet from the surface. The crew consists of the foreman, miner operator and miner helper, two (2) shuttle car operators, repairman, and a face utility man. Three (3) men perform maintenance, cleaning and rock dusting work on the beltlines from the surface to both working sections. Five (5) men (repairmen) are scheduled to perform maintenance work on the North Mains Section located 2700 feet from the surface. The foreman is the responsible person for this shift. An old abandoned mine (Widow Kennedy Mine) is located approximately 140 feet below this mine in the area at the #2 belt drive/transfer point. The old Widow Kennedy Mine, mined back in the 1970’s was known for liberating large amounts of methane. The primary escapeway is #4 entry for both the North Mains and West Mains Sections. The alternate escapeway is #3 entry (beltline entry) for both North Mains and East Mains Sections. Fifteen (15) SCSR’s are stored at cc #10 in both the primary and alternate escapeways, one crosscut outby the North Mains – West Mains junction. This mine is not known for liberating large amounts of methane but when the barometric pressure drops, more methane than normal is detected. Also, when the barometric pressure drops, the beltman that performs on-shift belt examinations has detected.2% to.3% methane in the belt entry near the #2 belt drive. A cold front has been moving through the area and it has been raining and snowing for the past two days. Four wheeled (battery powered) mantrips are used for transportation. The West Mains section crew normally travels the #4 entry (primary escapeway) to the working section. The North Mains section crew normally travel the #3 beltline entry alternate escapeway) to the working section.

4. The preshift examination of the face areas conducted at 5:00 AM and 6:30 AM, respectively revealed the following: NORTH MAINS WEST MAINS #1 entry -.3% Ch4 and 20.8% O2.1% Ch4 and 20.8% O2 #2 entry -.4% Ch4 and 20.8% O2.1% Ch4 and 20.8% O2 #3 entry-.1% Ch4 and 20.8% O2 0% Ch4 and 20.8% O2 #4 entry-.0% Ch4 and 20.8% O2 0% Ch4 and 20.9% O2 #5 entry-.0% Ch4 and 20.8% O2 0% Ch4 and 20.9% O2

5. The mine operator and foreman plan to conduct a safety talk on the surface prior to the 15 men going underground. The company has just implemented a “New” production bonus plan. The mine operator discussed the “New” bonus plan and the foreman discussed electrical safety, locking and tagging out and cable maintenance. QUESTION A What other information could have and should have been discussed during the safety talk based on the mine map and information provided? ____ 1. The hazards of mining with underlying old mines that may contain methane. _____ 2. The effects that barometric pressure and weather storm fronts have on methane liberation in underground mines. _____ 3. The importance of conducting gas tests before and continuously while cutting and welding. _____ 4. The importance of installing check curtains and face line curtains when the outside man calls inside reporting a State or Federal inspector outside. _____ 5. The two mine disasters (Sago and Kentucky – Darby) that resulted from methane explosions.

6. QUESTION A - ANSWERS 1.CORRECT – Explosions and dangerous situations have occurred when old mines have cracked into active mines releasing methane, blackdamp, etc. One explosion in Virginia occurred when an old mine cracked 143 feet into an overlying active mine releasing methane which resulted in an explosion. 2.CORRECT – All miners must understand that weather fronts (cold, rain, snow) cause the barometric pressure to drop which results in an increase in methane liberation in coal mines. 3.CORRECT – Continuously monitoring for methane while cutting and welding is critically important in all coal mines. 4.INCORRECT – Section ventilation as well as all mine ventilation is critically important to prevent accumulations of methane at all locations in the mine. The presence of inspectors should not determine when miners should maintain proper ventilation. 5.CORRECT – Explosions can occur in any coal mine. Mines that have underlying old, abandoned mines may present extremely dangerous conditions, especially those known to liberate large amounts of methane. All miners must stay alert in a mine that has an underlying mine, as your mine could crack into the old mine causing an inundation of methane, carbon dioxide, etc.

7. The West mains crew arrived on the section and started producing coal. The maintenance crew arrived on the North Mains section and started cutting/welding bit lugs on the continuous miner ripper head. The outside man is standing near the front-end loader, approximately 40 feet from the #3, #4 and #5 portals. It’s 7:30 A.M., at which time, the outside man always eats his sausage/egg biscuit and drinks a large cup of coffee. The mine operator departed the mine site to go to Bill’s Electrical Supply Co., located 30 miles away, to buy some electrical supplies. The outside man feels a sudden outrush of air from the portals and observes coal/rock dust and debris in the air exiting from the portals. At this mine, the outside man feels most likely that an explosion has occurred underground. QUESTION B What are some priority things that the outside man must think about and do? ____ 1. Immediately try to contact all underground personnel, especially the foreman, who is the responsible person on this shift. _____ 2. Try to contact the mine operator. _____ 3. Notify the next-of-kin of all miners underground and tell them that an explosion has occurred at the mine and that no contact has been made with any of the miners since the explosion. _____ 4. Deenergize all underground electrical power while leaving the mine fan circuit energized. _____ 5. Get the emergency contact notification list (sheriff, state police, mine rescue teams, State and Federal officials, etc.) and put near the public telephone so appropriate personnel can be notified as quickly as possible.

8. QUESTION B - ANSWERS 1.CORRECT – This is the first thing that the outside man should do in any case of an underground mine emergency. 2.CORRECT – After the outside man attempts to contact everyone underground. 3.INCORRECT – The mine operator or his agent should determine when and how the next-of-kin should be notified. 4.CORRECT – All underground electrical power should be deenergized immediately. The fan circuit must remain energized. 5.CORRECT – This is a difficult situation, as is all mine emergencies. Several different people and agencies must be notified as quickly as possible.

9. WEST MAINS CREW The West mains continuous miner crew is moving the miner across the LOCC between the #2 and #3 entry – face areas. Several of the crew are installing timbers on each side of a roof fall that had occurred in the 3 rd crosscut outby the face area, between the #2 and #3 entries. The foreman is helping move the continuous miner. The crew heard a loud noise that sounded like an enormous roof fall which lasted for about 5 seconds. The crew felt a vibration and a change of pressure in their ears. They also felt a sudden inrush of air, followed immediately by the section being inundated with rock and coal dust and small, flying debris. About one (1) minute later, the electrical power deenergized on the section. The foreman and crew think immediately that an explosion has occurred on the North Mains section or somewhere outby their section. QUESTION C What is the “first thing” that the foreman should do? ____ 1. Go immediately to the mine telephone, located at the section loading point, call the outside man and try to determine what has happened and where. _____ 2. Account for and assemble all his crew on the West Mains section. _____ 3. Go to the mine telephone, after accounting for all his crew, call the outside man and instruct him to try to contact the North Mains section crew and the belt crew. And, also to contact everyone on the emergency personnel notification list. _____ 4. Anticipating that an explosion has occurred and that poisonous mine gases were created as a result of the explosion, assemble the crew and start building a barricade in the #3 entry, face area inby the LOCC because this will be the best location to barricade with the largest area of fresh air at this time.

10. QUESTION C - ANSWERS 1.PARTIALLY CORRECT – But only after the foreman has accounted for all his crew. 2.CORRECT – Accounting for all his crew is the first thing that the foreman must do following any mine emergency. 3.CORRECT – Notifying the outside man and reminding him to try to contact everyone else in the mine and notifying everyone on the emergency personnel notification list is the second thing to be done following any mine emergency. 4.INCORRECT – A crew should barricade ONLY after verifying that all means of escape are blocked or too hazardous to travel.

11. NORTH MAINS CREW/BELT MAINTANANCE CREW The North Mains maintenance crew were performing maintenance and cutting/welding work on the continuous miner when they also heard a loud noise that sounded like an enormous roof fall that lasted 3 to 5 seconds. The crew felt a sudden inrush of air, filled with small debris, rock dust and coal dust. The crew smelled a burned smell. All five (5) miners were located at the continuous miner. About one (1) minute later the electrical power on the section deenergized. The three (3) belt men were located near crosscut #9 when they felt a sudden outrush of air, saw coal dust, rock dust and small debris suspended in the air and immediately traveled toward the surface. The North Mains crew does not have a foreman. QUESTION D What are some of the things that the North Mains crew should do immediately? ____ 1. Designate one person as a crew leader. _____ 2. Send two people to the mine telephone, located at the section loading point, to call the outside man to try to determine what has happened and where; that it appears an explosion has occurred outby their location and that the five of them are O.K. at this time and that they will try to escape from the mine out the #4 entry (primary escapeway). _____ 3. The other three miners should go to the first aid box to get the escapeway map and carbon monoxide (CO) detector. _____ 4. Everyone should get their readily accessible SCSR (located within 25 feet) and make preparations to assemble at the previously established emergency meeting place (mantrip station). _____ 5. The entire crew should go get the carbon monoxide (CO) detector from the first aid box, then go get the barricade materials located in #5 entry and barricade themselves in #5 entry – face area - inby the LOCC.

12. QUESTION D - ANSWERS 1.CORRECT – Someone needs to step up and volunteer or be designated as the leader of the group. 2.CORRECT – All these things are very important to communicate to the surface as soon as possible after any mine emergency. 3.CORRECT – Very important. The CO detector and escapeway map may be life- saving during any mine emergency. 4.CORRECT – Seconds may save lives in getting their readily accessible SCSR’s. Poisonous gases may enter any area in the mine very quickly following a mine explosion. 5.INCORRECT – Barricade ONLY when all escape routes are blocked or too hazardous to travel.

13. NORTH MAINS CREW Two of the crew members travel to the first aid supply box and get the carbon monoxide (CO) detector, where it is normally stored. As soon as he activates the detector and conducts a test, he detects 150 ppm – CO at the mantrip station. A secondary mine telephone is located at the end of the lifeline in the primary escapeway. QUESTION E What are some things that the crew should be thinking about and/or doing at this time? ____ 1. Barricade themselves inby the LOCC in #5 entry – face area. _____ 2. Immediately try to call the outside man on the secondary mine telephone to try to determine what has happened and where and that the five of them are O.K. at this time. _____ 3. After trying to call the outside man on the secondary mine telephone, disconnect the telephone to put on the mantrip to take with them. _____ 4. Everyone should donn their SCSR due to 150 ppm – CO detected in the area. _____ 5. Each man should make sure they have their “second SCSR” and start evacuation by crawling down the #3 entry (beltline entry) – alternate escapeway because 150 ppm – CO was detected in #4 entry (primary escapeway).

14. QUESTION E - ANSWERS 1.INCORRECT – Barricade ONLY when all means of escape are blocked or too hazardous to travel. 2.CORRECT – Attempting to contact the outside man as soon as possible immediately after any mine emergency is very important. 3.CORRECT – The secondary mine telephone, located at the end of the lifeline in the primary escapeway, may not have damaged by the explosion and the crew should take a mine telephone with them in case they can travel outby where the telephone line may not be damaged and could be used. 4.INCORRECT – Donning SCSR’s may not be necessary in 150 ppm – CO, as this amount of CO can be inhaled for several hours without any appreciable effect. 5.INCORRECT – Never try to escape from any mine emergency by walking or crawling any escapeway, if you have a means and it’s safe to ride transportation equipment. You can always ride much faster than you can walk or crawl, especially crawling in low coal seams.

15. NORTH MAINS CREW The five man crew decided to use the mantrip to attempt escape from the mine out the #4 entry (primary escapeway). The crew loads the “secondary mine telephone” and tether line on the mantrip. The crew traveled two (2) crosscuts outby the mantrip station encountered “light smoke”. One of the crew members conducts a gas test and detects 900 ppm – CO. QUESTION F What should the crew do now? ____ 1. Stop the mantrip and donn their SCSR’s. _____ 2. Retreat back to the section and barricade themselves inby the LOCC in #5 entry – face area. _____ 3. Retreat back to the section on the mantrip and attempt escape from the mine out the #3 beltline entry (alternate escapeway) or one of the return air entries (#1 or #2). _____ 4. Each man should open and activate both of their SCSR’s, just in case one of them does not operate properly.

16. QUESTION F - ANSWERS 1.CORRECT – The presence of smoke, even light smoke, and the large increase in CO – from 150 to 900 ppm, tells you that the atmosphere is becoming poisonous very quickly. Never wait until you go from light smoke to dense smoke or into an irrespirable atmosphere before you donn your SCSR. Remember the ALMA mine fire and the problems that the miners had when they traveled through light smoke and entered dense smoke before they began to open and donn their SCSR’s. 2.INCORRECT – Barricade only when all means of escape are blocked or too hazardous to travel. 3.INCORRECT – The crew should remember that the #3 beltline entry (alternate escapeway) is blocked to mantrip travel by the feeder and will be a loss of valuable time. The return air entries should be the last choices as a means of escape and should only be traveled when intake air entries are blocked or too hazardous to travel. Smoke and/or poisonous gases will be present in the return entries following any mine emergency. 4.INCORRECT – Only open and donn one (1) SCSR. Your secondary SCSR is a spare and should only be opened when necessary to transfer to a new SCSR.

17. NORTH MAINS CREW The crew has donned and activated their SCSR’s and are traveling the #4 entry (primary escapeway) in the mantrip. The crew arrives at the mouth of the section and observes that the return air overcasts from the West Mains section have been destroyed and are blocking their travel with the mantrip. The crew observes ”dense smoke” and feel heat in the #4 and #5 entries at this location. The crew observes that the lifeline has been torn into by the explosion forces and destruction of the overcasts. QUESTION G What should the crew do now? ____ 1. Retreat back to the section on the mantrip and attempt to escape out the #3 beltline entry (alternate escapeway) or one of the return air entries (#1 or #2. _____ 2. Retreat back to the section and barricade themselves inby the LOCC in #5 entry – face area. _____ 3. Depart the mantrip – take the additional SCSR’s, tether line, secondary mine telephone and escapeway map and retreat inby to the door located two (2) crosscuts inby the overcasts; travel into the #3 – beltline entry and continue evacuation by crawling out the beltline entry. Travel in dense smoke should occur only if other escapeway entries are blocked or too hazardous to travel. Escape travel should occur in an entry equipped with an intact lifeline, if possible. _____ 4. Get the tether line off the mantrip and attach to each person before traveling through the door into the #3 beltline entry, just in case that they were to encounter dense smoke.

18. QUESTION G - ANSWERS 1.INCORRECT – The #3 beltline entry is blocked to mantrip travel by the feeder. The crew should realize this before returning and attempting travel in this entry. The return air entries is the last place that you want to be following any mine emergency and should be your last choice as a means to escape from any mine emergency. In this case, it would result in a loss of valuable time because all access routes to the return entries are blocked by equipment that cannot be moved (power is off). 2.INCORRECT – Barricading is always the last resort as previously discussed. 3.CORRECT – An alternate escapeway should be traveled at this time. The secondary mine telephone, secondary SCSR’s and the tether line may become valuable during escape from any mine emergency. The “tether line” is critically important because you may have to travel in smoke in an entry that does not have a lifeline and provides a means for the miners to stay together. 4.CORRECT – The tether line is critically important for the miners to have at all times while attempting escape.

19. NORTH MAINS CREW The crew traveled through the door into the #3 beltline entry. They encounter dense smoke and feel heat but are able to maintain contact with the lifeline as they escape. The crew has arrived at crosscut #10, in the #3 belt entry (alternate escapeway) where the SCSR’s are stored. The crew observes that the telephone line in this entry is destroyed. One crew member recommends that each of them get two (2) new SCSR’s for each of them from the storage box. QUESTION H What should the crew do now? ____ 1. Each crew member should only get one (1) SCSR from the storage box. _____ 2. Each crew member should get two (2) SCSR’s from the storage box because everyone else in the mine was probably killed by the explosion and won’t need SCSR’s. _____ 3. The crew should remove the spare CO detector from the storage box to take with them as they escape. _____ 4. Each crew member should transfer to a new SCSR even though they’re still breathing O.K.

20. QUESTION H - ANSWERS 1.CORRECT – You should never get more than one(1) new SCSR from a storage box because other miners attempting escape may need the additional SCSR.s 2.INCORRECT – Never get more than one (1) SCSR from any storage box. 3.CORRECT – If available, a spare CO detector may be invaluable during an escape. 4.INCORRECT – You should never transfer to a new SCSR just because it’s available. Transfer only when needed.

21. SCENE SHIFTS TO THE SURFACE The outside man attempted to contact both section crews and the belt maintenance crew but was unsuccessful. He also had deenergized all underground electrical power but left the mine fan circuit energized. The outside man has also contacted the mine operator, State and Federal officials, local sheriff and State Police, EMS and mine rescue personnel. All officials have been notified and are enroute to the mine. While reattempting to contact all personnel underground by the primary mine telephone and the secondary mine telephone, the mine operator arrived back at the mine. The three (3) belt men arrived on the surface just as the mine operator pulled onto the parking lot. The mine operator could not get much information from the belt men before they went home. They were really scared and all they could tell him was that they were at crosscut #9 in the belt entry when they felt a sudden outrush of air with coal dust and rock dust suspended in the air and they immediately traveled to the surface. QUESTION I What are some of the first things that the mine operator should consider doing? ____ 1. Verify that all necessary officials have been notified and are enroute to the mine. _____ 2. Contact the local pastor that has been pre-arranged and request that he report to the predetermined location (church) to be with the families and friends of the missing miners. _____ 3. Contact the next-of-kin of the missing miners and provide information/directions to the predetermined location (family staying area). _____ 4. Get the five (5) extra SCSR’s and put on the other mantrip; donn his SCSR and travel into the mine - #4 entry (primary escapeway) to look for the missing miners because this is most likely the first choice escape route that the miners may be traveling

22. QUESTION I - ANSWERS 1.CORRECT – The mine operator or agent should always verify that all necessary officials have been notified and are enroute to the mine. The mine operator or agent is required to notify State and Federal officials as soon as possible, not to exceed 15 minutes, if necessary to get to a telephone. 2.CORRECT – Notifying a pre-arranged pastor and requesting that he come to a pre-determined location is critical for the families and friends of the missing miners. 3.CORRECT – Notifying the next-of-kin of the missing miners is critically important. The next-of-kin should not receive this terrible information on the street or from the news. 4.INCORRECT – ABSOLUTELY NEVER DO THIS!!!! Never donn an SCSR and go into a mine to look for missing miners following any mine emergency. SCSR’s are used for escape purposes only.

23. OFFICIALS ARRIVE AT THE MINE The State and Federal officials, mine rescue personnel, State and local police and EMS personnel, have arrived at the mine. The police establish a security boundary at the junction of the mine road with the main road. State and Federal officials, mine rescue personnel and the mine operator establish a command center in the mine office where mine maps, a mine telephone and a public telephone are located. The mine operator briefs the other officials and provides the following information. 15 men were underground when apparently a mine explosion occurred; 7 men were assigned to produce coal on the West Mains section; 5 men were assigned to perform maintenance work on the North Mains section and 3 belt men were assigned to perform routine belt work; The 3 beltmen exited the mine about 5 minutes after they felt a sudden outrush of air, coal dust and rock dust; they were located at crosscut #9 when the event occurred; they were scared to death and have gone home. Dense smoke has been exiting the exhausting mine fan housing since about 10 minutes after the apparent explosion; An old, extremely gassy, abandoned mine is located underneath our mine about 140 feet in the general area at the #2 belt drive – transfer point; The fan gauge shows a reduced fan pressure – just about half of what it normally is since the incident occurred. State and Federal officials, mine rescue personnel, and the mine operator develop a recovery plan that consists of: 1.Initially exploring up the #4 and #5 entries to the 6 th crosscut and tie across into the #3, #2 and #1 entries; 2.And then continuing exploring the #4 and #5 entries to the 10 th crosscut and then tie across to the #3, #2 and #1 entries.

24. SCENE SHIFTS TO THE WEST MAINS SECTION The crew realized that most likely a mine explosion had occurred outby their location. The foreman had used the mine telephone at the loading point to try to call the outside man to try to determine what had happened and where, but had been unsuccessful. The foreman has accounted for his crew and have assembled at the mantrip station. QUESTION J What should the foreman and crew be thinking about and/or doing at this time? ____ 1. One crew member should attempt to call the outside man by using the secondary mine telephone required in the primary escapeway located near the end of the lifeline. _____ 2. The foreman should conduct a gas test immediately to determine the amount of oxygen carbon monoxide (CO), and methane at this location. _____ 3. Send a couple men to retrieve the escapeway map from the first aid box to take with them during the emergency evacuation. _____ 4. Take all his crew, travel to the #3 entry, inby the LOCC in the face area and barricade.

25. QUESTION J - ANSWERS 1.CORRECT – The secondary telephone may not have been damaged by the explosion and could be used to contact surface personnel. 2.CORRECT – VERY IMPORTANT!! The crew needs to know the types and amounts of gases that they have immediately after any mine emergency, especially CO in this apparent explosion incident. 3.CORRECT – The escapeway map may be invaluable in any attempt of emergency escape. This map must absolutely be kept up-to-date at all times. 4.INCORRECT – Barricading is always the last resort as previously discussed.

26. WEST MAINS SECTION The foreman tried to contact the outside man using the secondary mine telephone (located near the lifeline in the primary escapeway) but also was unsuccessful. The foreman and his crew have retrieved the escapeway map, tether line and secondary mine telephone and board the mantrip for evacuation. Electrical power on the section had deenergized approximately one minute after hearing the loud noise and rock/coal dust inundating the working section. The foreman had conducted a gas test immediately after feeling the sudden inrush of air onto the section and had detected 850 ppm – CO and 18% oxygen. The foreman and crew have boarded the mantrip. The foreman conducts a second gas test before departing the section, approximately three (3) minutes later and detects 1150 ppm – CO. QUESTION K What should the foreman and crew be thinking about and/or doing at this time? ____ 1. Go get the barricade material, retreat to the face area and barricade inby the LOCC, in #3 entry in the face area. _____ 2. Realize the urgency of immediate escape by realizing that the electrical power is off in the mine, that the pump located in the #4 entry primary escapeway will be inoperative and that water will accumulate rapidly blocking mantrip travel through this area. _____ 3. Everyone should donn their SCSR immediately because the CO is increasing rapidly and will be approaching the poisonous level very quickly. _____ 4. Travel back to the LOCC and wait 30 minutes for the ventilation to improve and reduce the amount of CO in the area.

27. QUESTION K - ANSWERS 1.INCORRECT – Barricading is the last resort as previously discussed. 2.CORRECT – The crew must realize that with electrical power off in the mine, including the pump located in the primary escapeway, that water will accumulate rapidly and block their escape in the intake escapeway. TIME IS CRITICAL WHEN WATER IS NOT BEING PUMPED - MAY BLOCK ESCAPEWAYS AND TRAVELWAYS. 3.CORRECT – The CO is increasing rapidly. In three (3) minutes, the CO increased from 850 ppm to 1150 ppm. The crew should donn their SCSR’s immediately because the CO is increasing at such a rapid rate. CO above 1500 ppm becomes dangerous to breathe after one (1) hour. 4.INCORRECT – A rapid escape is critical in any mine emergency situation. The mine ventilation will not improve, because most likely permanent stoppings have been destroyed and/or damaged causing a short – circuit in the ventilation.

28. WEST MAINS CREW The crew travels as quickly as possible toward the surface in the #4 entry (primary escapeway). As they approach the No. 2 pump area located (10 th crosscut outby the face area), they smell a burned smell, detect 250 ppm – CO and encounter water roofed in both the #4 and #5 entries. QUESTION L What should the crew do now? ____ 1. Retreat back to the section and attempt to escape to the surface out the #3 beltline entry (alternate escapeway) or one of the return air entries (#1 or #2). _____ 2. Retreat back to the section and barricade. _____ 3. Try to swim through the water since the dip is only about 50 feet in length. _____ 4. Everyone should depart the mantrip; get both of their SCSR’s; get the tether line and secondary telephone; travel through the door and attempt further escape by crawling out the #3 entry (beltline entry – alternate escapeway).

29. QUESTION L - ANSWERS 1.INCORRECT – The #3 beltline entry is blocked to mantrip travel by the feeder. The crew should realize this before returning and attempting travel in this entry resulting in loss of valuable time. Never attempt escape in a return air entry unless all intake air entries are blocked or too hazardous to travel. Smoke and or poisonous gases will be in the return entries, especially if the fan is operating and officials will be trying to keep the fan operating to provide fresh air in the intake entries where miners will be attempting escape. In this case, it would result in loss of valuable time because all access routes to the return entries are blocked by equipment that cannot be moved (power is off) or the roof fall. 2.INCORRECT – Barricading is the last resort as previously discussed. 3.INCORRECT – Never attempt swimming through water. 4.CORRECT – Crawling the #3 beltline entry (alternate escapeway) is the only means of escape. The crew can’t ride the beltline from the section because the feeder is blocking the #3 entry. Miners may consider removing a stopping to gain access to the belt entry with the mantrip but this would be a waste of valuable time in this situation because the overcasts at the mouth of the section were destroyed by the explosion and has the entry blocked to mantrip travel.

30. WEST MAINS CREW The crew travels to the “door” located in the 8 th crosscut outby the face area, between the #3 (beltline entry) and #4 entry (primary escapeway). The crew forgot to get the secondary mine telephone off the mantrip. The foreman opens the door and sees “light smoke”. QUESTION M What should the foreman and crew do now? ____ 1. Travel on through the door and evacuate out the #3 (beltline entry – alternate escapeway). _____ 2. Stop, sit down and pray. _____ 3. Everyone should attach themselves to the tether line; donn their SCSR’s before traveling on though the door into the #3 entry (alternate escapeway). _____ 4. Travel back to the section and barricade inby the LOCC in #3 entry face area.

31. QUESTION M - ANSWERS 1.INCORRECT – The “light smoke” that the foreman saw when he opened the door may turn to “dense smoke” very quickly. Never wait to donn SCSR’s when smoke is encountered. It is much more difficult to donn SCSR’s in “dense smoke” REMEMBER – the difficulty that the miners at the ALMA mine fire had while traveling from “light smoke” into “dense smoke” before opening/donning their SCSR’s. 2.CORRECT – EXCELLENT IDEA. 3.CORRECT – The miners attaching themselves to the tether line and donning their SCSR’s before going through the door may prove to be life-saving in this situation. 4.INCORRECT – As previously discussed in several questions.

32. WEST MAINS CREW The crew has tied themselves to the tether line, donned their SCSR’s and followed (crawled) the lifeline located in the #3 beltline entry (alternate escapeway) to the mouth of the section. The crew encounters “dense smoke” at the mouth of the section, which limits visibility to arm’s length. The crew had forgot and left their secondary mine telephone on the mantrip. The foreman observed that the telephone line was destroyed by the explosion at the #2 belt drive transfer area. The crew arrives at cc #10 where the SCSR’s are stored. At this time, four (4) miners are having problems breathing through their SCSR. QUESTION N What should the crew do now? ____ 1. All the miners should transfer to a new SCSR just because they have become available. _____ 2. Only the four (4) miners having breathing problems should transfer to a new SCSR and the other miners should obtain a new SCSR to take with them as they continue escaping from the mine. _____ 3. Disconnect the four (4) miners having breathing problems from the tether line and leave them to travel behind at a slower speed because they probably won’t be able to make it to the surface and will slow the travel rate of the other miners.

33. QUESTION N - ANSWERS 1.INCORRECT – Never transfer to a new SCSR just because you have access to it. An additional SCSR may become necessary later to safely escape from the mine. Every ounce of oxygen may prove to be critical in any mine emergency situation. 2.CORRECT – Only the miners having problems breathing through their SCSR should transfer at this time. Don’t transfer SCSR’s unless you need to. 3.INCORRECT – Always try to keep all the miners tied together with the tether line. A tether line with all the miners attached may have saved the lives of two miners at the ALMA mine fire.

34. WEST MAINS CREW The crew has arrived at crosscut #10 in the #3 beltline entry (alternate escapeway) where the SCSR’s are stored. The foreman observed that the telephone line is virtually destroyed at this location. The four (4) miners having breathing problems have transferred to new SCSR’s and are breathing O.K. now. The other miners get one (1) SCSR for each miner from the storage box. The crew continues evacuation out the #4 entry (primary escapeway). The crew arrives at the dip (4 th crosscut in the mine – No. 1 pump area) and joined the North Mains crew where the water in #4 and #5 entries had roofed. The foreman took one (1) man with him and traveled back to the 6 th crosscut and traveled through the door into the #3 - beltline entry. Then, they traveled outby in the #3 – beltline entry to the dip area and observed that the entry beltline was also blocked with water. Water is within 2” of the mine roof. The two men retreat back to the 6 th crosscut and the foreman opens the door between #2 and #3 entries and observes “dense smoke” in the #2 entry (return air entry). The foreman took a gas test and detected 19% oxygen and 150 ppm – CO in the #3 entry at the 6 th crosscut.. QUESTION O What should the foreman do now? ____ 1. The foreman and his buddy should retreat back to where the remaining crew members are located at the water roofed area in #4 entry (primary escapeway). _____ 2. The foreman should return to the #4 entry where the miners have a mine telephone; connect the mine telephone to see if he can contact the outside man and report their location, physical condition and conditions present at their location. _____ 3. The foreman should retreat back to where the remaining crew members are located at the water roofed; get with the other miners and attempt escape out #1 or #2 return air entries because it’s only six (6) crosscuts to the surface. _____ 4. The foreman and his buddy should continue travel on through the door into the #2 return air entry and try to find their way to the surface, even through the “dense smoke with zero visibility”.

35. QUESTION O - ANSWERS 1.CORRECT – The foreman is the leader and should return to the rest of the crew to inform them of conditions he observed in the #2 and #3 entries. 2.CORRECT – A telephone that a crew can take with them during any escape may very well save their lives. In this case, the crew has arrived at a location where the telephone line was usable. Miners should attempt to contact personnel on the surface as soon as possible when a means becomes available. Surface personnel need to know the following ASAP from escaping miners: (1) location and conditions; (2) no. of miners and their condition; (3) no. and location of miners left in the mine. 3.INCORRECT – Take time to think this through. You know that the #2 – return entry is filled with dense smoke, with zero visibility and there’s no lifeline. If an attempt were made to escape through this dense smoke and even though its only six (6) crosscuts to the surface, it would be very easy to get disoriented and travel inby in the wrong direction. The foreman and crew must realize by now that a fire has occurred as a result of the explosion and filling the #1 and #2 return air entries with dense smoke and poisonous fire gases. Mine rescue personnel will advance in the escapeway entries (#3 and #4) as quickly as possible first to look for missing miners. 4.INCORRECT – Making a decision to travel in dense smoke in a return entry is a dangerous decision. Other means of escape should be evaluated prior to making the decision to do this.

36. BOTH WEST MAINS/NORTH MAINS The foreman and his buddy decide not to travel into the “dense smoke” in #2 return entry and they retreat back to #4 entry (primary escapeway) at the water roofed area where the other miners are located. The foreman conducts a gas test and detects 19% oxygen and 150 ppm – CO. Realizing this concentration of CO is not dangerous, he removed his SCSR. The foreman observes that the telephone line is not damaged at this location; hooks up the mine telephone and calls outside. The mine operator answers the telephone. The foreman reports that 12 men are blocked by water in the #3, #4 and #5 entries and that “dense smoke with zero visibility” is present in #2 entry and they are afraid to enter the dense smoke. The mine operator advised the 12 miners to stay at the water roofed area in the #4 entry and that two mine rescue teams have built airlocks in #4 and #5 entries and are preparing to pump the water and that the mine rescue teams should be at their location within the next 5 minutes. QUESTION P What should the foreman and miners do now? ____ 1. Follow the instructions of the mine operator and stay at the water roofed area in #4 entry. _____ 2. Try to keep all the men together and exit the mine out #2 entry, even though :dense smoke with zero visibility” is present in this area. _____ 3. Stay at the water roofed area, monitor the safety of the miners. _____ 4. Cut the lifeline and tie everyone to it and try to crawl through the water roofed.

37. QUESTION P - ANSWERS 1.CORRECT – Miners who receive instructions from mine rescue personnel and or mine officials should obey their instructions. 2.INCORRECT – Traveling through dense smoke with zero visibility in a return air entry is dangerous as previously discussed. 3.CORRECT – Even though 5 minutes may seem like hours or an eternity in this situation, the miners should wait at the water roofed as instructed May be a good time to thank God for his blessings of life. 4.INCORRECT – Never try to crawl through water, even while wearing an SCSR.

38. The foreman and crew decide to follow the instructions of the mine operator, mine rescue and State and Federal officials and stay at the water roofed area in #4 entry (primary escapeway). The mine rescue teams pump the water and assist the 12 miners to the surface. The 12 miners are examined by EMS personnel and appear to be O.K. except for being physically exhausted and scared. ALL 15 MINERS HAVE SAFELY ESCAPED!!!!!
