The PICS allowed workers to stay in the work area much longer than normally allowed, while keeping their body temperatures in a safe range. The ice and pump unit is in a nylon pack with a waist or shoulder strap harness. Ice-chilled tap water flows past an ice reservoir, then through the tubes, cooling the worker.
Workers control the rate of cooling by controlling the flowrate of water with a two position switch.
The workers are significantly cooler and more comfortable, more productive, and able to stay in the work area longer. Stay time extentions based on using the PICS can only be granted by an Industrial Hygienist who is monitoring the conditions and the workers. Under oversight by an Industrial Hygienist, the Personal Ice Cooling System cool suits can be used to increase safety by keeping workers cool, reducing the risk of heat stress. Delta Temax, Inc.
