The NEC requires you to put a simple 'advisory' label on just about everything that could be serviced while energized. NFPA 70E, and many customer specifications, requires equipment to have labels that spell out PPE or the amount of incident energy. So the answer depends on which code you are subject to.These labels cannot be handwritten (other than portions of the label that may have variable values or information that is subject to change). The new code language also includes an informational note referencing ANSI Z535.4-2011, Product Safety Signs and Labels which provides guidelines on how to make proper hazard signs and labels.
