The purpose of the report is to study the practical usefulness for tank crews of an individual-collective protection system against chemical warfare agents. The Canadian Army Chemical Warfare Laboratories have developed a gas-protection system for the Ram Tank series, consisting of a positive supply of purified air through face masks to each crew member and sealing materials for closing hull openings to eliminate entry of liquid agents. The basic plan behind the development of this method of CW protection is based upon two broad principles to reduce the probability of direct contamination of tank crews by liquid CW agents, to provide a positive supply of decontaminated air for breathing through a facepiece which would be sufficiently comfortable to be worn continuously. Ideally, the facepiece should be preferred for use at all times regardless of the gas hazard, thus eliminating the possibility of casualties from a surprise gas attack. This method of protection is not to be considered as a substitute for positive-pressure ventilation of the crew compartment. It is a major interest as a means of providing protection in tanks now in the field, whereas the positive-pressure lends itself particularly to incorporation into new models of tanks.
