Abstract:
Excessive swelling or deterioration of the elastomer
seal (o-ring and its lubricant) in the fire suppressant
storage container could lead to leakage of the agent
leaving the system unready to respond in case of fire.
Short term exposure experiments have been conducted and
data have been generated on the proclivity of the eleven
fluid agents to alter the properties of various
elastomers and greases. The compatibilities of the fire
suppressant agents with commonly used elastomers and
greases have been characterized using two types of
measurements.
