1.04 <br /> D. Temperature Hazards <br /> 1. Heat Stress <br /> 1 When temperature exceeds 70°F,take frequent breaks in shaded area. <br /> Unzip or remove coveralls during breaks. Have cool water or <br /> electrolyte replenishment solution available. Drink small amounts <br /> frequently to avoid dehydration. Count the pulse rate for 30 seconds <br /> as early as possible in the rest period. If the pulse rate exceeds <br /> — 110 beats per minute at the beginning of the rest period, shorten the <br /> work cycle by one-third. <br /> 2. Cold Stress <br /> NE Wear multilayer cold weather outfits. The outer layer should be of <br /> wind resistant fabric. <br /> NE 0'to -30°F total work time is 4 hours. Alternate 1 hour in and 1 hour <br /> out of the low-temperature area. Below-30°F, consult industrial <br /> hygienist. <br /> NE Drink warm fluid. Provide warm shelter for resting.

Consult <br /> DHSO and Corporate Health and Safety Policy prior to entering confined space. <br /> NE Obtain permit for confined space entry <br /> NE Monitor OZ and organic vapors before entering. If following values are <br /> exceeded, do not enter: <br /> 02 less than 19.5 percent or greater than 25%. <br /> Total hydrocarbons greater than 5 ppm above background, <br /> if all air contaminants have not been identified. <br /> Concentrations of specific contaminants exceeding action <br /> level in Section 19 if all air contaminants are identified. <br /> NE = NOT EXPECTED <br /> G:\w1AGDH\GH41017G.356 12 <br />
