Bruce is a sales director for Shafer Enterprises LLC/Cool Shirt (www.coolshirt.net). You can reach Cool Shirt at (800) 345-3176. Cool Shirt® manufactures apparel that doubles as a portable cooling station. Cool Shirt® uses the same fittings on all its products so when you need to combine the portable system with a cooling station, workers will be able to pre-cool prior to using the portable unit and simply unplug from one and plug into the other through the use of universal fit, “dry break” fittings.
According to the OSHA Technical Manual, which prescribes workloads for workers under temperatures typically experienced outdoors during the summer months, to keep from exceeding the Threshold Limit Value (TLV) when the ambient temperature is above 86° F, the work regimen will consist of 25 percent work and 75 percent rest.
