w <br />• <br />Cold Stress <br />• Wear multilayer cold weather outfits. The outer layer should be of wind resistant <br />fabric. Drink warm fluid. Provide warm shelter for resting. Use the buddy system. <br />Avoid heavy sweating. <br />Attachments 11 and 12 of this HSP addresses the heat and cold stress hazards. <br />Noise Hazards <br />• Use earplugs when noise level prevents conversation in normal voice at a distance of 3 <br />feet. <br />1 Additional standard operating procedures are described in Attachment 4. <br />Monitoring Procedures <br />Is Perimeter Identified? Yes Is Site Secured? Yes <br />• The exclusion zone will be indicated with flagging tape or chain fence. The zone will <br />be determined by the OSHSO and will be based on areas needed for successful <br />equipment operation and the results of air monitoring. <br />• No one shall be allowed to enter an exclusion zone without the required PPE. <br />Personnel entering an exclusion zone shall comply with all restricted area entry and <br />exit procedures. <br />Is a Map/Site Sketch Attached with the exclusion zone, contamination reduction zone, and <br />support zone identified? (See Site Map) Yes X No <br />To perform initial site survey and subsequent periodic monitoring, a PID will be <br />available. This monitoring will continue during the course of work. <br />• A PID will be used to detect the total concentration of many organic and inorganic <br />gases and vapors. The 10.2 eV lamp span will ensure the significant range of <br />detectable chemicals. Attachment 8, addresses the limitations of the instruments. <br />• Initial air monitoring for identification of toxic contaminants will be qualitative, (i.e. <br />the contaminant or the class to which it belongs is demonstrated to be present.) <br />• PID calibration gas consists of approximately 100 ppm isobutylene in an air matrix <br />that is referenced to benzene. The meter reading obtained during calibration is <br />' marked on the gas counter label. Most calibrating gas canisters supplied by HNu have <br />a label set up with particular ppm to be read with a span of 9.8 for 10.2 eV lamp and <br />10 for 11.7 eV lamp. Calibrations should be performed daily. <br />' • Prior to start of work airborne, concentrations will be measured within the exclusion <br />zone boundaries and in the breathing zones of workers for a minimum of 10 minutes. <br />A-12 <br />G <br />
