This ammonia refrigeration systems checklist supports safe operation and loss prevention for industrial and food manufacturing sites. It guides risk assessments including hazardous, operability and regulatory reviews such as DSEAR, ATEX and COMAH. The checklist covers plant room location and construction, controlled access, penetrations, explosion relief, electrical classification, ventilation and monitored extraction. It includes leak detection strategy, alarm set points at 25 percent and 50 percent of the lower explosive limit, and interlocks for ventilation and equipment shutdown. Fire detection and suppression, housekeeping, inspections, training and permit to work are addressed. It also details cylinder storage controls and a robust emergency response plan with evacuation, PPE, liaison with authorities and regular drills.
