Gratings and Walkways
Gratings
Attachment
Gratings are used as machine or mud pit guards as well as a walking surface. Check that they are secured and do not move when employees walk or step on them. Check that hinged gratings are equipped with a pop-up handle that does not present a trip hazard and that the grating has some way to hold it open to prevent crush injuries from a falling grating hatch.
Gratings covering belt drives, conveyors, or moving machinery must be bolted down securely and identified as needing a lockout/tagout procedure if you need to remove the grating.

Condition
Look for corrosion or rust that may affect the load carrying capacity of the grating panel.
Load Rating
Clearly post the load rating in the area. Load bearing grating should not be bent or broken and should never be covered with boards or plywood intended to reinforce or repair damaged grating.
