Subpart D Walking Working Surfaces General Industry
61 flashcards covering Subpart D Walking Working Surfaces General Industry for the OSHA OSHA 10/30 General Industry section.
Subpart D of OSHA's general industry standards addresses hazards related to walking and working surfaces, such as floors, stairways, ladders, and platforms, to prevent slips, trips, and falls in workplaces. This is defined in the Code of Federal Regulations, 29 CFR 1910, Subpart D, which applies to most non-construction settings.
On OSHA 10/30 certification exams, this topic typically features in multiple-choice questions that ask about specific requirements, like guardrail heights or ladder safety protocols, often using real-world scenarios. A common trap is overlooking exceptions for certain surfaces or misapplying rules from construction standards.
One tip workers often miss: Always check for hidden hazards like uneven surfaces during routine walkthroughs.
