a) Door Panel Construction. Typical exterior personnel
doors used with conventional construction are commonly 1-3/4 inches (45 mm)
thick and typically faced with 16- or 18-gauge (1.5- or 1.2-mm) steel.
Although some doors are hollow, others commonly are filled with a
noncombustible foam or a slab of polyurethane. Locking devices for personnel
doors vary; however, they are typically a five- or six-pin tumbler type.
Hinges are of mortised design with nonremovable pins. It should be noted
that such features are only furnished when specified (as an extra cost
option). Estimated penetration times for standard personnel doors are
uniformly low.
In evaluating the penetration times of door surfaces,
consider doors required to have panic bar hardware as special cases. These
doors do not require a man-passable opening to be defeated. Drilling a small
aperture to pass a wire hook through is all that is required to open them.
The tradeoffs between life safety and security may impact directly upon
interior layouts to avoid a design that must be compromised to meet fire
protection requirements.
Personnel door panel/edge details for low-severity threat
level protection are shown in Table 25. The door panel is constructed of 16-
gauge (1.5-mm) steel with 16-gauge (1.5-mm) steel stiffeners. Edge
construction is a 14-gauge (1.9-mm) recessed channel. Fully welded
construction is employed.
