Safety and Power Saws
SAFE WORK WITH POWER SAWS
Thousands of workers are badly injured each year by gas or electric saw. Some are killed most by electric shock.
You can be badly cut or burned, using a power saw, if you are not careful. You can get sprains and strains and lose your hearing. Grit and dust from using the saws can hurt your eyes. Dust can hurt your lungs. If you dry-cut masonry or stone that has silica in it, you can get silicosis and it can kill you. An electric saw can electrocute you. A gas-powered saw can cause carbon monoxide poisoning and kill you.
Read the owners manual before you first use a saw. Keep blades sharp, clean, and oiled. Inspect blades for cracks.
When you use a saw, wear goggles, safety glasses with side shields, or a face shield. Do not wear jewelry, such as chains. Do not wear loose clothes. If you have ling hair, tie it inside your hard hat. Wear hearing protection. Do not cut unless you have a clear work area and solid footing. Do not use a power saw when you are on a scaffold. Keep other people away from the saw when you are using a refueling it.
Training: Make sure you receive training before using any unfamiliar tools or equipment. OSHA says you must be trained in general workplace hazards, electric hazards, and personal protective equipment. (PPE)/
Here is how to protect against the main hazards Lung Diseases. Do not dry-cut masonry or stone or you can get lung disease. Cutting brick, cement, concrete, or stone can make a lot of dust-and there can be silica in it. (Silicosis can kill you). We cutting is the best way to control dust.
Local exhaust ventilation can capture the dust at the blade. As a last resort, your boss may give you a respirator. If you use a respirator, OSHA says your employer must have a full respirator program, which includes proper selection and fitting of respirators, medical screening to be sure you can wear a respirator, and worker training to use respirators.
Electrocution. An electric saw needs to be double-insulated or have a 3 prong plug in a grounded outlet. And a saw needs a ground-fault circuit interrupter. Unplug a saw before you change a blade. Be extra careful when working in wet grass or near a puddle. If you are cutting toward any wires, make sure they have been disconnected. OSHA says you must not use worn electric cords or cables. Do not use electrical equipment in damp, wet, or very hot locations.
Cuts and amputations. Make sure the saw blade is not touching anything before you turn on a saw. Do not drop-start a chainsaw. To start a saw with a starter cord, put on e foot on the back handle, put one hand on the top handle to keep the blade off the surface, and use the other hand to pull the cord. OSHA says a circular saw must have a guard above and below the base plate. Keep the blade guard and other safety devices on the saw. Make sure the blade guard goes back to the fully guarded position after you cut.
Hold a saw with both hands. Do not use your leg to prop a saw. To prevent kickback, hold your forward arm straight and do not cut above chest height.
After you turn off a saw, hold it away from you until the blade stops turning. Do not prop the saw on your leg while the blade slows down. Turn off a saw before you carry it anywhere.
Burns. What you cut can catch fire from friction. A spark from a saw can ignite any gasoline leaking from the saw. Make sure there are no fuel leaks and the fuel cap is tight. Turn off the saw and let it cool down before you refuel it.
Sprains and strains. When you can, put your work on a solid surface at waist height. Try not to work bent over or in other awkward positions.
Carbon monoxide. If you use a gas-powered saw where there is not a lot of fresh air carbon monoxide can kill you fast. This can happen in a crawl space or even in a big parking garage. You cannot see or smell carbon monoxide gas. Fans can help keep fresh air coming in, but fans are not always enough. If you can, use an electric saw instead of a gas-powered saw. OSHA has special rules for controlling toxic gases in enclosed spaces and for PPE. Your employer must follow the OSHA rules for using PPE and work in a confined space. A competent person should monitor the air with special equipment while the work is done.back
