Unformatted text preview: the power saw from his right hand to his left hand and was shocked. He fell from the ladder into a puddle of water, still holding the saw. The current had caused his hand to contract, and he was "locked" to the saw. A co-worker disconnected the power cord to the saw. CPR was given, but the shock was fatal. Attention to these general safety principles could have prevented this death. Any and all electrical equipment involved in a malfunction should be taken out of service immediately. The carpenter should have taken the saw out of service, not just the extension cord. (As it turns out, the saw was the source of the shocks, not the cord.) Although the homemade extension cord does not seem to have contributed to this incident, it should not have been used. The floor truss should not have been used as a ladder. For climbing, use only approved ladders or other equipment designed specifically for climbing. Do not work in wet areas. The water should have been removed from the floor as soon as it was found. Humidity and perspiration can also be hazards. Try to stay as dry as possible, be alert, and take action to protect yourself when needed. OSHA requires that all receptacles at construction sites that are not part of the permanent wiring have GFCIs. Be aware that shocks can cause you to lose your balance and fall, often resulting in more severe injury. wire. Power tools with metal housings or only one layer of effective insulation must have a third ground wire and three-prong plug. Use multiple safe practices--Remember: A circuit may not be wired correctly. Wires may contact other "hot" circuits. Someone else may do something to place you in danger. Take all possible precautions. Wear and maintain PPE. Wear correct PPE
OSHA requires that you be provided with personal protective equipment (PPE). This equipment must meet OSHA requirements and be appropriate for the parts of the body that need protection and the work performed. There are many types of PPE: rubber gloves, insulating shoes and boots, face shields, safety glasses, hard hats, etc. Even if regulations did not exist requiring the use of PPE, there would still be every reason to use this equipment. PPE helps keep you safe. It is the last line of defense between you and the hazard. Page 70 Section 8 Wear safety glasses--Wear safety glasses with side shields or goggles to avoid eye injury. They should have a Z87 stamped on them to show they are certified by the American National Standards Institute Z87 Standard for eye and face protection. Wear safety glasses to avoid eye injury. Wear proper clothing--Wear clothing that is neither floppy nor too tight. Loose clothing will catch on corners and rough surfaces. Clothing that binds is uncomfortable and distracting. Contain and secure loose hair--Wear your hair in such a way that it does not interfere with your work or safety. Wear proper foot protection--Wear shoes or boots that have been approved for electrical work. (Tennis shoes will not protect you from electrical hazards.) If there are non-electrical hazards present (nails on the floor, heavy objects, etc.), use footwear that is approved to protect against these hazards as well. Wear a hard hat--Wear a hard hat to protect your head from bumps and falling objects. Hard hats must be worn with the bill forward to protect you properly. Wear hearing protectors--Wear hearing protectors in noisy areas to prevent hearing loss. Follow directions--Follow the manufacturer's directions for cleaning and maintaining PPE. Make an effort--Search out and use any and all equipment that will protect you from shocks and other injuries. Don't wear hard hats backwards! Arcing electrical burns through the victim's shoe and around the rubber sole. Think about what you are doing. PPE is only effective when used correctly. Section 8 Page 71 PPE Fact Sheet--The right Equipment--Head to Toe
PPE is the last line of defense against workplace hazards. OSHA defines PPE as "equipment for the eyes, face, head, and extremities, protective clothing, respiratory devices, protective shields and barriers." Many OSHA regulations state that PPE must meet criteria set by the American National Standards Institute (ANSI). Head Protection
OSHA requires that head protection (hard hats) be worn if there is a risk of head injury from electrical burns or falling/flying objects.
HEAD PrOTECTION How do I wear and care for my hard hat?
Always wear your hat with the bill forward. (Hats are tested in this position.) If you wear a hat differently, you may not be fully protected. The hat should fit snugly without being too tight. You should clean and inspect your hard hat regularly according to the manufacturer's instructions. Check the hat for cracks, dents, frayed straps, and dulling of the finish. These conditions can reduce protection. Use only mild soap and water for cleaning. Heavy-duty cleaners and other chemicals can damage the hat. Don't wear another hat under your hard hat! Aren't all hard hats the same?
No. You must wear the right hat for the job. All hard hats appr...
