ABSTRACT:
Safety equipment is described for use by firemen which includes an air tank (42, FIG. 2), a harness (14), a face mask (16), and a PASS (personal alert safety system 20), which assures that the PASS will be activated whenever the equipment is worn. The equipment includes a switch system with at least one switch (31-35) mounted on the equipment at a position to receive force as the equipment is mounted on the fireman, to set or actuate the PASS. The switch (31-34) can sense the force of the equipment against the fireman's body, and/or the switch (35) can sense buckling of a harness belt (48).
