Toolbox Talk – Machine Guarding
Overview
Machine Guarding — Hand & Power Tools Overview Many power tools and machines used on construction sites have guards on them to protect you from the danger of hazardous moving parts such as belts, gears, shafts, pulleys, sprockets, spindles, drums, fly wheels, chains, or other reciprocating, rotating, or moving parts of equipment. These moving parts must be guarded, as per OSHA requirements, if they are exposed.
For discussion…
The common types of equipment on which you might find machine guards include circular & other power saws; jointers; routers; grinders; conveyors.
As necessary, guards are provided to protect the operator and others from:
Point of operation hazards
Nip point hazards
Rotating parts
Flying chips and sparks
Never remove safety guards when the tool is being used or in operation. If the guard is not on, you are exposed to hazards from the moving parts of the machine or tool being used.
Circular saws must be equipped with blade guards. The upper guard must cover the entire blade. A retractable lower guard must cover the teeth of the blade except when it makes contact with the work material. Then, the lower guard must automatically return to the closed position when you’re finished making the cut. Otherwise, you may be exposed to the cutting action of the blade.
Many times, these guards are bypassed or removed because a worker believes he can get more done without it. By doing this the worker exposes himself to unnecessary risks of cuts, being hit by flying objects, and other hazards.
So, don’t take chances with machine guards. Make sure they’re in place on tools, equipment and machines that require them. If they’re missing, tag out the equipment and turn it in for repairs. Protect yourself and others.
Questions
1. Are guards always in place on the equipment you use?
2. Is there ever an excuse for not using the guard?
3. Why does OSHA insist that guards be in place when power tools are in use?
4. Who is responsible for inspecting your job site hand and power tools?
