General Safety

What is an Accident? An unplanned event that may or may not result in an injury

CAUSES OF ACCIDENTS 90% of accidents are caused by human error. 10% of accidents are caused by unsafe conditions in the surroundings.

Safety Over 2 Million people are injured at work each year and 11,500 die from their injuries ½ of all work accidents are caused by carelessness, improper use of equipment or lack of safety gear. Injuries today can plague you for the rest of your life! Think about it.

8 Guidelines for Safety Develop a safe attitude A safe worker thinks about safety and then acts on it. Don’t get caught after the fact saying “I just wasn’t thinking.” Never act without considering the safest way to complete the task.

8 Guidelines for Safety 2. Stop, look and listen Be aware of your surroundings. What do you see and hear? What machines are in use, is someone working behind you? Look before you turn!

8 Guidelines for Safety 3. Take the time to do it right. Those who take pride in their jobs are usually safer than those who rush. Select the right tool for the job and use it properly. Its not worth the risk of injury to rush!

8 Guidelines for Safety 4. Keep tools and equipment in good working order. If a tool is not working right … its dangerous! If there is any concern or evidence that a tool is damaged or not functioning properly, let Mrs. Johnson know IMMEDIATELY.

8 Guidelines for Safety 5. Keep your work area clean and neat Think about trip hazards Think about knives hidden under rags and other tools Clean away any and all messes that you make.

8 Guidelines for Safety 6. Anticipate problems before they occur If you see a potentially dangerous situation do something about it! Don’t wait until somebody gets hurt Don’t wait to be asked to fix a dangerous situation …. Take initiative. The person you save from injury may be you

8 Guidelines for Safety 7. Dress for the job Use of PPE: Personal Protective Equipment Always wear the right safety equipment Always wear protective eyewear!!!! Wear appropriate clothing No open toed shoes Tie back long hair No loose sleeves or jewelry that snag and pull you in Keep pants and shirts at the right length

8 Guidelines for Safety 8. Follow the Rules Most accidents can be avoided if everyone follows the rules. Horseplay can put you and others in danger. Horseplay will always result in a ZERO for the entire unit!!!! Don’t do it! No food or drink of any kind in the materials lab. Never use tools until you have been instructed to do so and tested on their use.

Tools Always inspect tool before using it If damaged report it to your teacher immediately Never touch a power tool if it is moving, wait until it comes to a complete stop. Always use the tool for it’s proper function.

ALWAYS WEAR EYE PROTECTION WHEN WORKING IN THE LABORATORY! Safety Glasses Eye Glass Side Shields Goggles Full Face Shields

Most common tools used in this lab. Hand Tool Safety Hand Tools Most common tools used in this lab.

Hand Tool Safety Keep clean and in good condition (before and after use) Use tools that are in good condition Use for designed purpose Use properly Safety goggles Keep cutting tools sharp Carry sharp/pointed tools with point down and away 18

Scissors Treat with respect. Use properly. If they break or are broken inform instructor immediately.

Easy Cutters Scissor like tool with razor sharp blade and plate for precision measuring Use with eye protection Keep safety on when not in use.

Glue Guns Treat with respect. Glue is hot and will cause blisters. Use properly, protect counters and table tops. Unplug from the plug, not the cord.

Utility knives Retractable razor blade for cutting cardboard and wood material Use with eye protection when cutting wood strips Keep blade in when not in use. Pull toward self, with hand over the top

Using Power Tools in the Laboratory Always get permission from the teacher before you use the machinery. Never talk to another student or the instructor while he/she is operating the machinery. When using the machinery stand only in the “Operator Zone” or the area where only the machinery operator should stand. Always unplug a power tool by the plug not the cord.

Types of Machines Drill Press – When cutting holes make sure the material is secured in a Vise or Gripping Tool. Never hold the material. Band Saw – Use the guide to push material through the blade and keep your hands from the blade. Never force material, forcing means you are trying too hard and could bind. Scroll Saw – Move material slowly, keep your hand away from the blade. Sander – Hold material firmly, always move against the spin.

When in the Laboratory… The Laboratory is a dangerous place if you are not careful. Never Horse Play. Never Operate the machinery without checking with the teacher. Loose hair should be tied up, clothing tucked in, jewelry taken off, and long sleeves rolled up. If an accident should happen contact the teacher immediately.

Materials Paint, enamel, lacquer, or solvents must not be used near flames or sparks because they are flammable. Keep flammable materials in the metal cabinet. Never leave material lying around someone could get cut, slip, or fall. Hot metal placed in water can cause the water to be hot enough to burn someone.

X-acto knives ALWAYS cut on the cutting mat NEVER cut towards your body Keep your fingers out of the way DON’T freehand cut, ALWAYS use cork ruler Measure twice and cut once Some materials you need to score a few times before cutting through the material. Don’t try to “man-handle” it and cut through in one swipe because the material could slip. NEVER walk around with a knife in your hand If you need a new blade, I will come to you  Standing up to cut always works better than sitting down No horse playing Keep cap on knife when not in use

ALWAYS CLEAN UP THE LABORATORY BEFORE YOU LEAVE!!!!
