If you are responsible for safety in your company, it is not just OSHA that you should be aware of. NFPA, ANSI, and other regulations play a role, as well.
In many instances, OSHA will refer to building codes that are spelled out in NFPA standards, for example. One such example is illuminated exit signs for emergency exits. OSHA does not specifically mention inspecting the signs, but they reference NFPA 101, which requires monthly inspections of illuminated signs. That means you must test each sign monthly, with longer tests at other times.
OSHA also references ANSI in other instances, such as their specifications for machine guarding.
If you do not know where to find these regulations, it becomes difficult to know what rules you are supposed to follow. Here, I break down where to find these regulations and some of the most common ones that apply.
