![]() ![]() The TLV® pocket guide from the American Conference of Governmental Industrial Hygienists (ACGIH, Cincinnati) provides corrected heat stress limits for some garments. The maximum length of time the chemical protective clothing can be worn depends on variables such as the air supply, ambient conditions, climate inside the ensemble, physical and psychological conditions of the wearer, work rate and work load. If you or your co-workers have symptoms of heat stress such as nausea, dizziness, high heart rates, or excessive heat build-up, leave the work area immediately and remove the ensemble as quickly as possible after decontamination and seek professional care. (Note: Do not wear cooling vests in potentially flammable or explosive environments.)īe aware of the symptoms and treatment of heat stress. ![]() Implementing a conservative work/rest schedule or using a cooling system like the DuPont™ Cool-Guard® vest may be effective in reducing heat stress. This can lead to a rise in core body temperature and heat stress. If you determine that you are in a potentially flammable or explosive environment, retreat immediately.Ĭhemical protective clothing can interfere with the natural regulation of body temperature. Do not knowingly enter an environment in which the concentration of flammable gas is within flammable or explosive limits while wearing a Tychem® 2000 garment. Do not wearTychem® 2000 chemical protective garments in potentially flammable or explosive atmospheres. However, in the case of explosive or flammable atmospheres, even if steps are taken to manage static formation and dissipate static charge, the risk of severe injury remains if an uncontrolled or accidental ignition occurs. In these situations, suggested steps include, but not limited to, water spray, the use of an overcover, raising humidity level of the work area, use of a commercial, anti-static application coating, grounding straps on equipment and personnel, inherently static-dissipating under- and over-garments, and testing of the worker's static dissipation before entry into the classified area. When operating around flammable chemicals, take steps to eliminate potential static discharges. Discharges are not normally dangerous except in situations where the generation of an electrical spark could ignite a flammable atmosphere or startle the wearer. Under certain conditions, such as cold and dry weather, it is possible that garments might build and discharge static electricity. In order for any garment system to be static dissipative, it must be able to drain a charge buildup through proper grounding devices, such as, but not limited to, workstation grounding clips or static-dissipative floors. In situations where static dissipation level is a critical performance property, end-users should evaluate the performance of their entire ensemble as worn including outer garments, inner garments, footwear and other PPE. ![]() ![]() The substrate used to make Tychem® 2000 garments is treated with a topical antistatic agent to help minimize static build up and reduce nuisance garment cling. ![]()
