confined, prevented by ventilation, or present in an adjacent Class I, Division 1
location, but where an abnormal situation might result in intermittent exposure to
such ignitable concentrations.
While the PS-B unit is a non-incendive device under ANSI/ISA 12.12.01 and CSA
C22.2 N

213, it is not designed for, and should never be used within a Division 1
(normally hazardous) location.
PS-B units are suitable for use in Class I, Division 2, Groups A, B, C, and D
