PREVENTION OF COLD STRESS <br /> Exposed skin surfaces should be protected by use of appropriate cold protective clothing. <br /> These protective items can include facemasks, handware, and footware. Employees should <br /> wear cold protective clothing for the level of cold and physical activity with an objective to <br /> protect all parts of the body with emphasis on hands and feet. Provisions for keeping the <br /> workers hands warm in addition to use of insulated gloves include use of warm air jets and <br /> radiant heaters. Adequate insulating clothing to maintain body core temperatures above 36°C <br /> should be used. The use of extra insulating clothing and/or a reduction in the duration of <br /> exposure period are special precautions. Wet or damp clothing should be changed as soon as <br /> possible. During periods of extreme cold (10°F or less), workers should use the buddy system <br /> for constant protective observation. <br /> 6.2 Noise <br /> It is anticipated that heavy equipment will generate noise during site operations. If deemed <br /> necessary by the SSHO, monitoring for occupational noise exposure for these activities will be <br /> conducted. A portable hand held Type 11 Sound Level Meter (SLM) will be used for noise <br /> surveying. All noise measurements will be taken in the "hearing zone" of the individual. All <br /> measurements used for comparison with noise compliance levels will be made on the A- <br /> weighted scale. <br /> When noise monitoring data indicates noise levels at or exceeding 85 dBA averaged over 8 <br /> hours, hearing protection will be required as per the Cal-OSHA standard for occupational noise <br /> exposure, Title 8 CCR, Article 105. <br /> Rough&Ready Island 19 Tetra Tech,Inc. <br /> Revised Draft HSP November 18, 1998 <br />
