OSHA Compliant Guard-Opening Scale, Measuring Device –
An OSHA guard-opening scale is a valuable tool to use during the design, installation, and inspection of guards to make sure they comply with OSHA safety standards. This folding guard-opening scale is based on Table O-10 of OSHA 29 CFR 1910.217 for mechanical power presses. It shows the distances that guards shall be positioned from the point of operation based on opening size. When a guard is used as the primary safeguarding method, it must be designed, constructed, adjusted, and maintained so that someone cannot reach under, over, around, or through the guard. Any openings created by the guards must be checked for compliance with the OSHA safety standards.
