ISA TR92.00.03 – Guide for Toxic Gas Detection as a Method of Personnel Protection

Toxic gas detection in process safety management provides personnel protection by minimizing the probability of toxic gases reaching hazardous levels. Criteria are developed to establish toxic gas levels to initiate alarms, initiate increase in ventilation rates and to initiate shutdown of processes generating the toxic gas that has breached containment. This guide provides techniques for the use of toxic gas sensors and controllers to monitor and control sources of toxic gas release into the atmosphere within designated spaces in industrial locations.
