CMD Personal Protective Equipment Management Program 2.15 3.6.8 Climactic Conditions The human body works best with few restraints from clothing. Protective clothing adds a body burden by increasing weight, restricting movement, and preventing the body's natural cooling process. In severe situations, a modified work program must be used. Some materials act differently when they are very hot and very cold. For example, PVC becomes almost brittle in frigid temperatures. If there are any questions about the stability of the protective materials under different conditions, the manufacturer should be contacted before using PPE in the field. 3.6.9 Work Load Like climactic conditions,the type of work activity may affect work duration and personnel's ability to perform certain tasks. Similarly, the amount of protective materials a person wears will affect their ability to perform certain tasks. For example, a person in a total encapsulating suit, even at 72T, cannot work for more than a short period of time without requiring a break. The work schedule should be adjusted to maintain the health of the employees. Modified work practices may include allowing more time for individual job tasks and implementing work/rest cycles per NIOSH and ACGIH thermal stress recommendations. Special consideration should be given to the selection of clothing that protects the worker and adds the least burden when personnel are required to perform strenuous tasks. Excessive bodily stress frequently represents the most significant hazard encountered during fieldwork. 3.6.10 Types of Protective Materials 1. Cellulose or Paper: suitable for nuisance dust and coarse fibers. 2. Natural and Synthetic Fibers a. TyvekTM: suitable small-sized hazardous particles, including lead, asbestos, and mold. b. TychemTM: is suitable for a variety of hazards, from light liquid splashes to heavy exposures to industrial chemicals and agents. c. NomexTM: is suitable for flame-resistance, radiation resistance, acids, alkalis, fluorocarbon refrigerants (CFCs), and non-polar solvents. 3. Elastomers a. Polyethylene: suitable for polar substances and solvents. b. Saran TM : suitable for flame-resistance, acids, alkalis, oils, and organic solvents. c. Polyvinyl Chloride (PVC): suitable for alcohols, oils, inorganic acids, alkalis, and salts. d. Neoprene: suitable for polar/non-polar substances, petroleum mixtures, and <_ 200 F heat resistance. e. Butyl Rubber: suitable for polar substances and solvents. f. Viton: suitable for non-polar substances, petroleum mixtures, and <_200 F heat resistance. g. Nitrile: suitable for polar/non-polar substances and petroleum mixtures. 3.7 Protection Levels 3.7.1 Level A Protection Level A protection (a fully encapsulated suit) is used when skin hazards exist or when no known data positively rule out skin and other absorption hazards.
