Dave Davidson, Maintenance/Compliance/Safty Supervisor at Signature Packaging and Paper asked:

Is it an OSHA or NFPA requirement to have locks on all my electrical panels, to prevent access, except for authorized personnel?

SafetyMan says:

Both OSHA and NFPA use the word "supervised" or "controlled" access to electrical panels meaning that only "authorized personnel" should be able to access them. If that means it must be locked to achieve that, then you lock the panels. If it means locating them in a locked room then that is what you do. Supervised control is the method that you decide which best suits your company. The question if you lock them, is where do you put the key?? In some situations, I have seen the key hanging beside the locked box! That definitely does not fit their requirements for "supervised" control.
