Hand and Power Tool Safety

Hand and Power Tool Safety We use tools frequently in everyday life. From a simple pair of scissors or a screwdriver to a complex metal-working machine, tools make our work easier. But no matter how simple, a tool used incorrectly can cause serious bodily harm. It is important to think before using any tool and consider the potential hazards. Make SAFETY a priority. There are two areas of concern when dealing with the proper use of tools – in this order: 1) Personal Safety – no one gets injured. 2) Tool Care – tools are not damaged. General Practices • • • • • • • • • • • Never work alone! Before working in a lab, know where the phone, fire alarm and emer­ gency exit is. Use the right tool for the job. If you don’t know what a tool is or how to use it, DON’T. If you don’t know what tool to use for a task, ASK. Return tools to their proper storage area when you are finished. Do not use paint (spray or brushed) or anything that gives off fumes in a closed room, go to a room with proper ventilation or outside. Dispose of sharp or potentially sharp objects in a designated container; this includes knife blades, glass (broken or whole), needles, nails, etc. Do not put your hand behind anything you are working on with hand or power tools. Nothing is a ladder except a ladder; make sure ladders are stable. Be sure to keep good footing and maintain good balance. Personal Preparation • • • • • • • • Hair – long hair should be tied back out of your way. Jewelry – remove rings, chains and other jewelry. Clothing – change loose or baggy clothing or make sure it is securely fas­ tened. Eyes – wear safety glasses at all times in a work area. Ears – wear ear protection if in a noisy area. Hands – wear leather gloves when handling rough wood and other materi­ als, do not wear gloves when operating power tools. Lungs – use a respirator if in a dusty area or if vapors are present. Feet – do not wear sandals or open-toed shoes. 1 • Mind – do not use power tools when you are ill, taking strong medications, fatigued or consuming alcoholic drinks. Work Area • • • • Lighting – make sure there is enough lighting to see what you are doing. Footing – make sure the floor is not slippery; no water or dust. Clamping – make sure your work piece is on a firm surface or securely clamped. Space – keep the work area clear and uncrowded. Tools – do not leave tools lying on the floor. Hand Tools • • • • • • • • • • Do not use a screwdriver or pliers on electrical equipment unless is it certified for electrical use. Never use a screwdriver as a hammer, chisel or pry bar. Use the correct hammer for the work being done. Have an unobstructed swing when using a hammer (overhead clearance and other people). When using a wrench, make sure it is the correct size. Always pull on a wrench, if it slips you won’t crush your fingers. Do not use wrenches or bars as extensions for hand tools. When using a knife, cut away from your body keeping hands and body away from the knife stroke. Make sure tools are sharp, dull tools can actually be more danger­ ous. Cover sharp tools when not in use. Power Tools • • • • • Do not operate power tools in damp or wet locations without Ground Fault Circuit Interrupt (GFCI) protection (the type of out­ let found in kitchens and bathrooms). Never carry a tool by the cord. Never yank the cord to unplug it. Make sure the cord is not in the cutting path. Do not operate a power tool if the cord or tool is damaged. 2 • • • • • • • • Unplug the tool before making any adjustments and when it is not being used. Use two hands on a power tool whenever possible. Place fingers so there is no danger they will slip into moving parts. Keep your finger off the trigger of a power tool when you aren’t actually using it. Give your job your full attention, do not look away or talk to oth­ ers. Never startle someone who is using a power tool. Observers and helpers should stand back, use the proper protec­ tive gear and follow the instructions of the tool operator. Parts that are being worked on can get very hot, be careful han­ dling them. Electrical Safety • • • • • Be sure power is off before working on electrical equipment or circuits. Do not defeat grounding plugs on equipment. Two-pronged plugs are usually polarized – it is dangerous to reverse polarization. Only use an extension cord when necessary and make sure it is the proper size for the current draw of the equipment. Do not use multiple power strips chained together. If you don’t feel comfortable using a tool, ask someone to do it for you! 3
