OSHA requires that machine guarding be provided and maintained in a manner sufficient to protect machine operators and other persons present in machine areas from hazards associated with the operation of machines. Such hazards include those created by points of operation, in-running nip points, rotating parts, flying chips and sparks. The following information is provided to assist machine operators and machine shop supervisors and managers in carrying out their responsibilities for assuring machine safety through hazard identification and evaluation, safeguarding, and safe operation.
Machine safeguards should be installed and maintained to ensure that they:
Safeguards must minimize the possibility of the operator or another worker placing their hands into hazardous moving parts.
Workers should not be able to easily remove or tamper with the safeguard.
Safeguards should ensure that no objects can fall into moving parts.
A safeguard defeats its purpose if it creates a hazard of its own.
A safeguard should not create an unacceptable impediment for the worker.
It should be possible to lubricate the machine without removing the safeguard.
