Pneumatic tools are powered by compressed air and include chippers, drills, hammers, sanders, spray guns, air ratchets, grinders, and many more.
There are several dangers associated with the use of pneumatic tools. First and foremost is the danger of getting hit by one of the tool’s attachments or by some kind of fastener that you are using with the tool.
Pneumatic tools must be checked to see that they are fastened securely to the air hose to prevent them from becoming disconnected. A short wire or positive locking device attaching the air hose to the tool also must be used and will serve as an added safeguard.
When using pneumatic tools, a safety retainer must be installed to prevent attachments such as chisels on a chipping hammer from being ejected during tool operation.
Pneumatic tools that shoot nails, rivets, staples, or similar fasteners and operate at pressures more than 100 pounds per square inch (6,890 kPa), must be equipped with a special device to keep fasteners from being ejected, unless the muzzle is pressed against the work surface.
If an air hose is more than 1/2-inch (12.7 millimeters) in diameter, a safety excess flow valve must be installed at the source of the air supply to reduce pressure in case of hose failure.
Eye protection is required, and head and face protection is recommended for employees working with pneumatic tools. Alert other workers in the vicinity to keep a safe distance when operating pneumatic tools.
