Air pumps should be placed within easy reach using an OSHA <br />approved ladder, elevated platform or by placing the pump on a <br />stake. Personnel should be thoroughly familiar with the use, <br />limitations and operating characteristics of the monitoring <br />instruments. <br />Perform continuous monitoring in variable atmospheres. <br />Use intrinsically safe instruments until the absence of <br />combustible gases or vapors are determined. <br />Proper protective clothing such as gloves and goggles should be <br />used when handling corrosive substances. 15 -minute eyewash <br />and first aid should be available. Handle and store corrosives in <br />appropriate areas. <br />Monitoring )Equipment and procedures: <br />OVM with 10.0 eV lamp. Take background readings in the area you do not <br />suspect to be contaminated. Let instrument run continuously, or set on <br />standby mode. Take readings in the breathing zone upon initiating site <br />work. Log readings at least every hour in the breathing zone. The OVM <br />should be consulted more frequently than every hour if there is a question <br />regarding appropriate action level. For an up -grade to be warranted, <br />readings in the breathing zone must persist for a time, i.e., 5 to 10 minutes. <br />This is a judgment call. Spikes on the OVM above the action level do not <br />call for an up -grade. <br />ACTION LEVELS: If readings are 0 to <25 ppm above background in the <br />breathing zone, continue to level D. <br />Readings from >25 to 100 ppm above background, in the breathing zone, <br />require Level C. Readings over 100 ppm in the breathing zone require up- <br />grade to Level B. <br />Team Members: <br />Site Safety Officer <br />Health and Safety Officer <br />Site Entry Procedures: <br />Name <br />Tom Landwehr <br />Kathy Brodrick <br />In <br />Responsibility <br />Site Safety Coordinator <br />Corporate Health and Safety <br />
