Abstract
A study was carried out to determine the concentration of Halon 1301 fire suppressing agent obtained within the crew compartment and engine compartment of the Cougar fire support vehicle and the Grizzly armoured personnel carrier, upon activation of their fire suppression systems. Measurements showed that the highest concentrations of agent obtained within the crew compartment and engine compartment of the Cougar were 3.2% v/v and 15.8% v/v, respectively. Similarly, the highest concentrations achieved in the crew compartment and engine compartment of the Grizzly were 6.7% v/v and 9.8% v/v, respectively. The concentrations of agent, which were measured in the crew compartments would not create an occupational hazard to occupants for up to 15 minutes of exposure; however, the concentration achieved within the crew compartment of the Cougar may be ineffective for fire suppression.
