1. The world leader in serving science Antaris EX and Hazardous Locations Overview Matt Ebersole August 13, 2007

2. 2 Hazardous Locations Defined  The National Electrical Code (NEC) defines hazardous locations as those areas "where fire or explosion hazards may exist due to flammable gases or vapors, flammable liquids, combustible dust, or ignitable fibers or flyings."  These areas are also called: Classified Locations Explosive Atmospheres (ATEX) HazLoc  NEC gives as an example: “drying rooms for the evaporation of flammable solvents” (Article 500). Pharmaceutical Dryer

3. 3 Hazardous Locations Defined  Equipment for these locations are referred to as: Listed Classified Labeled  Why talk about this? Some models of the Antaris EX are rated for hazardous locations Antaris Target Blend Analyzer is being tested for future hazardous locations ratings

4. 4 Worldwide Standards The governing codes are:  United States National Electric Code (NFPA 70) Article 500 National Electric Code (NFPA 70) Article 505, since 1996 NFPA codes  Canada Canadian Electric Code (CEC) CSA 60079  Europe – Directive 94/9/EC EN 60079  Other – IECEx Scheme, slowly being accepted May accept US or European rating

5. 5 Hazardous Area Classification  These areas are divided into three classes: Class I: Flammable Gases or Vapors Pharmaceutical plants Refineries and chemical plants Some food processing Gas stations, aircraft hangers and fueling, paint/spray areas, sewage treatment facilities, natural gas handling, printing presses Class II: Combustible Dusts Grain storage, flour and feed mills, metal grinding, pharmaceutical plants, producers of: plastics, fireworks, starch, candies, sugar, cocoa, spices, coal Class III: Ignitable Fibers & Flyings Textile, mattress, cotton mills, wool processing, wood cutting Antaris EX-Z1 & EX-Z2

6. 6 Hazardous Area Classification  European standards (94/9/EC) instead divide hazardous locations into: Group Group I: Mining, underground, firedamp Group II: All other installations Type of hazard G: gases, vapors, or mists D: dusts Both Antaris EX-Z1 & EX-Z2

7. 7 Hazardous Area Classification  Divisions, Zones, and Categories NEC Code 500 Division 1  exists under normal operating conditions  or may exist frequently due to repair, maintenance, or leakage Division 2  only in accidental rupture or breakdown or abnormal operation  only in breakdown of ventilation system  adjacent to C1D1 location Antaris EX-Z1 Antaris EX-Z2

8. 8 Hazardous Area Classification  NEC Code 505 – since 1996, and IEC60079 Zone 0  gases present continuously or for long periods of time Zone 1  gases likely to exist under normal conditions  or frequently for maintenance or leakage  adjacent to Zone 0 Zone 2  gases not likely to exist in normal operation, and if they do only for a short time  only due to breakdown or abnormal operation  only due to ventilation failure  Adjacent to Zone 1 Antaris EX-Z1 Antaris EX-Z2

9. 9 Hazardous Area Classification  Europe 94/9/EC Category 1  explosive atmosphere present continuously, for long periods, or frequently Category 2  explosive atmospheres likely to occur occasionally Category 3  explosive atmospheres unlikely to occur, and if they do, only infrequently and for a short period Antaris EX-Z1 Antaris EX-Z2

Amer

11. 11 Hazardous Area Classification How would you classify these areas? The mixing tank is open and contains volatile materials. A hood is provided over the tank. There is a valve to empty the tank. Fresh air comes in through the vents. More volatile product is stored in the walled-off, separately ventilated area.

12. 12 Hazardous Area Classification (2) = Zone 0 (hazard continuously present) (3) = Zone 1 (only intermittent hazard) (4) = Zone 2 (only abnormal hazard, such as barrel spill) (5) = Non-Hazardous

13. 13 Hazardous Area Classification Equipment is also classified by groups Some gases, such as Hydrogen, have higher explosive pressures and are harder to contain. Antaris EX-Z2 North America covers groups A, B, C, and D. Antaris EX-Z2 International covers group IIC (and all lesser groups). Antaris EX-Z1 North America covers groups C and D. Check labeling of system to be sure. More dangerous

14. 14 Hazardous Area Classification  Temperature Class Equipment is rated by the hottest surface temperature on or in the enclosure. This must be less than the ignition temperature of the gas the area is rated for. Antaris EX-Z2 and EX-Z1 are rated T4. Check labeling of system to be sure.

15. 15 Hazardous Area Classification  Ambient Temperature Standard operating temperature range for equipment in hazardous locations is -20°C to 40°C. All versions of the Antaris EX are rated for -20°C to 40°C.

16. 16 Markings  A note about different standards: Factory Mutual Approval We do not carry FM approval. They are a certification body, just like UL, or others. We use Intertek, which is a notified body in Europe and an OSHA approved NRTL for the US. CENELEC Approval “CENELEC approved” is the old term for ATEX. The ATEX directive, 94/9/EC, became mandatory July 1, 2003, repealing the old method (76/117/EEC, 79/196/EEC, and 82/130/EEC). While the CENELEC standards body still creates the standards used for all European regulatory approvals, ATEX is the new approval method.

17. 17 Working in Hazardous Locations  Some review on working in Hazardous Locations: Static electricity: sparks can set off explosions. Typically, ESD protection is used (straps, jackets, etc). Ordinary location electrical equipment is not allowed in the hazardous location (e.g. cell phones, meters, oscilloscopes, laptop computers, etc). Also, the enclosures cannot be opened to access the equipment being serviced while it is powered up. The above can often be overcome with a “hot work permit” or “safe work permit”. In Zone 1 and 2, where the hazard is intermittent, the atmosphere can be tested for the hazard, and then work can commence. The safe environment window for service can be very specific and very small. There may be on-site training required before you can enter. Always consult the local facility’s safety engineer or officer and strictly comply with his or her guidance and all local safety rules.

18. 18 Protection Techniques  The equipment needs to use one or more of the defined protection techniques.  Antaris EX-Z1 and EX-Z2 use a combination of some of these, but primarily type ‘p,’ purged and pressurized. Protection TechniquePrinciple Intrinsic Safety (ia)Limit Energy Flameproof (d)Contain the Explosion Purged and Pressurized (p)Keep Flammable Gas Out Oil Immersion (o)Keep Flammable Gas Out Increased Safety (e)No arcs, sparks, or hot surfaces Encapsulation (m)Keep Flammable Gas Out Powder Filling (q)Contain the Explosion Type ‘n’, non-sparking (nA, nC, nR)No arcs, sparks, or hot surfaces

21. 21 Antaris EX Product Overview  Antaris EX-IP Rated IP65 per IEC 60529 Hose down environment Also protected against dust Thermo Electric Cooler (runs from electrical supply) with closed loop control Can be purged, but not necessary (similar to standard Antaris) 110V OR 220V Only this system has a cart option. This system allows you to take an Antaris MX into an industrial environment. It is well suited for a loading dock where the temperature can be more extreme, or an area where there is dripping of material.

22. 22 Antaris EX Product Overview  Antaris EX-IP Concerns Use caution when rolling cart down ramps. Use caution when working inside the enclosure as there is hazardous voltage present. The enclosure may be purged with Nitrogen. Use caution when opening. Turn off the Nitrogen and allow the air to clear before putting your head inside. Power plug must be into an outlet rated for the area. The power cord comes with a normal plug on the end. If the area is washed down then the cord should go through a gland into an outlet box. The plug can also be removed for direct wiring into a junction box. Keep vents of cooler clear. System is not universal voltage. It is ordered for 110V or 220V based on the power cord selected. The cooler is the only part that is voltage specific. If the system is to be installed on a cart, then the service engineer may be unpacking the enclosure for installation. Keep all 4 door latches closed.

23. 23 Antaris EX Product Overview  Antaris EX-Z2 Rated for Division 2 or Zone 2 Must be ordered for North America or International Hose down environment Vortex Cooler (runs from purge supply) with closed loop control Universal input voltage Type ‘Z’ purge system Tested to NFPA 496 or IEC 60079-0 and 60079-2

24. 24 Antaris EX Product Overview  Antaris EX-Z2 Theory of Operation The enclosure is sealed, but because the sealing is not perfect the enclosure is pressurized at least 0.1 inches of water above ambient to keep out dangerous gases. After the door has been opened or the purge gas has been off, the enclosure must go through a purge cycle. A high flow of gas is pushed through for a certain amount of time to clear out any dangerous gases. Only after this is complete can the enclosure be powered on. The timing of the purge cycle is done manually. Connecting and disconnecting power is done manually. The system has an alarm available. These are contacts that open when the system is not pressurized. Because of hot components inside (source, etc.) that could ignite gases, it is not necessarily safe to open the door when the power is off. Only open the door if the area is known to be non-hazardous. If present, the keyboard is protected by “non-incendiary” design. It is certified to not product sparks that could ignite gases. See the manual for operating instructions. Read the warning labels.

25. 25 Antaris EX Product Overview  Antaris EX-Z2 Concerns Cooler is loud. Outside of cooler is very hot. Use caution when working inside the enclosure as there is hazardous voltage present. The enclosure may be purged with Nitrogen. Use caution when opening. Turn off the Nitrogen and allow the air to clear before putting your head inside. Do not open door unless the area is known to be non-hazardous. Do not power up system unless the purge cycle has been completed. Ordinary plant compressed air is not suitable as purge gas due to contaminants. We specify our usual purge gas guidelines. Electrical wiring inside enclosure will be required. Customer must supply means to cycle power to the system. Purge must be filtered well. Keep relief valve area clear. Keep all 4 door latches closed. Test the purge system after every service procedure.

26. 26 Antaris EX Product Overview  Antaris EX-Z1 Rated for Division 1 or Zone 1 Must be ordered for North America or International Hose down environment Vortex Cooler (runs from purge supply) with closed loop control Universal input voltage Type ‘X’ purge system Tested to NFPA 496 or IEC 60079-0 and 60079-2

27. 27 Antaris EX Product Overview  Antaris EX-Z1 Theory of Operation The enclosure is sealed, but because the sealing is not perfect the enclosure is pressurized at least 0.2 inches of water above ambient to keep out dangerous gases (higher pressure than Z2). After the door has been opened or the purge gas has been off, the enclosure must go through a purge cycle. A high flow of gas is pushed through for a certain amount of time to clear out any dangerous gases. Only after this is completed is the enclosure powered on. The timing of the purge cycle is automatic. Connecting and disconnecting power is automatic. When the pressure falls, all power and I/O signals are cut. There is a service bypass that will bypass the purge system and apply power immediately. It is designed so that it cannot accidentally be left in the system. The switches to cut the power are located inside an explosion proof box on top of the enclosure. This is designed to keep out that gases, but if there is a leak it will contain any explosion that may occur.

28. 28 Antaris EX Product Overview  Antaris EX-Z1 Theory of Operation The system has an alarm available. These are contacts that open when the system is not pressurized. Because of hot components inside (source, etc.) that could ignite gases, it is not necessarily safe to open the door when the power is off. Only open the door if the area is known to be non-hazardous. If present, the keyboard is protected by “intrinsically safe” design. “Barriers” inside the enclosure limit current and voltage to prevent energy that is large enough to ignite gases from passing out to the keyboard. See the manual for operating instructions. Read the warning labels.

29. 29 Antaris EX Product Overview  Antaris EX-Z1 Concerns Cooler is loud. Outside of cooler is very hot. Use caution when working inside the enclosure as there is hazardous voltage present. The enclosure may be purged with Nitrogen. Use caution when opening. Turn off the Nitrogen and allow the air to clear before putting your head inside. Do not open door unless the area is known to be non-hazardous. Do not power up system unless the purge cycle has been completed. Do not open the explosion proof box unless the area is known to be non- hazardous. Make sure the explosion proof box is sealed correctly and all of its ports are plugged.

30. 30 Antaris EX Product Overview  Antaris EX-Z1 Concerns Ordinary plant compressed air is not suitable as purge gas due to contaminants. We specify our usual purge gas guidelines. Electrical wiring inside enclosure will be required. Customer must supply means to cycle power to the system. Purge must be filtered well. Keep relief valve area clear. Keep all 4 door latches closed. Test the purge system after every service procedure.

31. 31 Antaris EX Product Overview  Antaris EX Vents The spectrometer has vents in its sidewalls on 3 sides. In the EX-Z1 and EX-Z2, these prevent pockets of gas from forming inside the spectrometer. They must not be covered up! In the EX-IP, these vents are covered up to improve spectrometer stability.

32. 32 Antaris EX Installation Process  2 Palettes, one with enclosure, one with spectrometer “Do not open” sticker on spectrometer box  Simple Antaris EX-IP installations (cart or table top mounting, not direct wired but plugged into wall outlet) Service engineer will install entire system Customer will need to help with moving the heavy enclosure into place  All other installations: Service engineer will: Check mounting, wiring, fiber optic routing Complete wiring connections inside enclosure Unpack spectrometer Install spectrometer Complete fiber optic connections inside enclosure Test spectrometer Help customer with I/O connections Test purge system (EX-Z1 and EX-Z2 only) Customer will: Unpack enclosure Mount enclosure Connect power into enclosure Run fiber optics into enclosure Connect purge supplies to enclosure Complete pre-commissioning form
