Locate or protect all detection equipment so that it is protected from any mechanical or physical impact that might make it inoperable. Fire detectors can be protected as follows:

• Use protective coatings or noncorrosive materials for corrosive atmospheres.
• Use canopies, hoods, or other suitable protection for weather protection.
• Use suitable cages or metal guards for protection from physical damage, or locate detectors where their contact with materials or equipment is not possible.
• Make sure detectors are supported independently of their attachment to wires or tubing.
