Safety in the Plant
protection ensembles and clothing for hazardous materials emergencies 2005 edition, these garments are available with standard polyester outer shell, or in Nomex IIIa which provides additional limited chemical flash-fire protection. In terms of other
features and benefits, Lac-Mac’s products: resist penetration of many liquid chemicals; have good breathability, reduce heat stress and improve productivity; have a tough, durable three-layer laminate provides long lasting garment life; have seams sealed with GORE-SEAM tape providing overall penetration resistance; and decrease costs over time because they are both washable and reusable. To assist users
in determining the proper applications for protective clothing, Lac-Mac colour codes different chemicals. For example, green represents liquid splash hazards as defined by NFPA 1992 Standards. GORE chemical splash fabric passes the penetration test for chemicals printed in green. Yellow denotes that the chemicals represent both potential
vapour and liquid splash hazards. Here GORE chemical splash fabric should only be used in controlled situations if vapour exposure is acceptable. “Consult a trained professional in industrial safety or hygiene when making this determination. Failure to comply with this warning may result in serious injury or death,” notes the company. A red colour code means that GORE chemical splash fabric fails the penetration test for such chemicals.
Heat stress Lac-Mac particularly emphasises the dangers of heat stress: “Heat stress is a serious hazard to wearers of chemical protective clothing. In some cases, heat stress may be even more dangerous than the chemical hazard itself. To release heat, your body sweats, and when the sweat evaporates, your body is cooled. Film materials such as vinyl or rubber protect against accidental contact with liquid chemicals but do not provide relief from heat stress. GORE chemical splash fabric provides liquid splash protection while maintaining comfort. Clothing made from this fabric allows your body to breathe, so your sweat can evaporate through the GORE membrane, providing you with some relief from heat stress. Because it is light and comfortable it generally can be worn for a full shift without excessive overheating.” ■
