Strange Observations – Signs on Fire-Rated Doors

Continuing in a series of strange things that I have seen while consulting at hospitals…

Doors to medical gas storage rooms are required to be fire-rated.

Fire-rated doors cannot have signs applied that cover more than 5% of the total surface of the door.

A sign that does not exceed 5% surface of the fire-rated door is approximately 8.5″ x 11″. This door has signs that exceed the 5% surface amount.

Also, the signs cannot be attached to the door using screws or nails, but must use adhesive.
