THE SAFETY OF FIREMEN WEARING BREATHING APPARATUS

Lawson, D.I., 1958. THE SAFETY OF FIREMEN WEARING BREATHING APPARATUS. Fire Research Notes 347


ABSTRACT

This note examines the problem of locating firemen in smokelogged buildings, and describes a communication system whereby the fireman is connected to the control point by cable. A source of sound on the fireman is operated from batteries at the control point, either manually or automatically should the fireman become unconscious. The control point is made aware by a local indicator if a state of alarm arises. The line is continuously monitored and both the control point and the fireman are alerted if the line should break. Telephonic facilities are also provided.
