The Occupational Safety and Health Administration (OSHA) has withdrawn its Walking Working Surfaces and Personal Fall Protection Systems rule, commonly referred to as “slips, trips and falls,” from review by the Office of Management and Budget (OMB).

It’s not clear what the reason for the withdrawal is, but OSHA appears committed to finalizing the rule, which was first proposed in 1990 and then reopened to public commentary in 2010-2011 and eventually submitted to OMB.

Under the OSH Act’s General Duty Clause, however, businesses still must maintain safe and healthy workplaces even as the agency reworks its slips, trips and falls rule.
