|These sections on equipment rooms are rewritten from the previous code to clarify where storage is allowed, and they remove the requirement for the rooms to be protected with a fire-extinguishing system, fire sprinklers. The electrical section specifies where storage is not allowed. It was not the intent of the code to prohibit storage in rooms that only had electrical circuit breaker panels. Storage around circuit breaker panels is addressed in Section 605.3.|
