Walking Working Surfaces

Q:  We have built a few small “platforms” to stand on to do some of our work.  When I say platform, I mean a small single step.  These “platforms” range from about 7-9 inches tall with a rectangular flat service of 18X18 inches on the small end, and 30X36 inches on the larger end. Is there an OSHA requirement that a surface area must be so large for a certain height? 
A:  Yes, OSHA does have requirements for steps.  The platforms you are talking about will be covered by those requirements for steps.  The regulations that will want to follow for the structure and surface area are as follows:
  • 1910.24(c) "Stair strength." Fixed stairways shall be designed and constructed to carry a load of five times the normal live load anticipated but never of less strength than to carry safely a moving concentrated load of 1,000 pounds.
  • 1910.24(d) "Stair width." Fixed stairways shall have a minimum width of 22 inches.
Regarding your question about the need for handrails, the only need for a handrail is if the platform is 4 feet or more above an adjacent floor or ground.  In your case the two steps that total 16 inches would not need a handrail:  click here to refer to 1910.23(c)(1) - 1910.23(c)(1)(iii).
