LFR, Inc. <br /> 10.0 ACTION LEVELS <br /> The following action levels were developed for exposure monitoring with real-time air <br /> monitoring instruments as specified in Section 5.1. Air monitoring data will determine <br /> the required respiratory protection levels at the Site during scheduled intrusive <br /> activities. The action levels are based on sustained readings indicated by the <br /> instrument(s). Air monitoring will be performed and recorded at up to 30-minute <br /> intervals. <br /> If elevated concentrations are indicated, the monitoring frequency will be increased, as <br /> appropriate. If during this time, sustained measurements are observed, the following <br /> actions will be instituted, and the Project Manager and Director of Health and Safety <br /> will be notified. For purposes of this HSP, sustained readings are defined as the <br /> average airborne concentration maintained for a period of one (1) minute. <br /> Activity Action Level Level of Respiratory Protection <br /> Soil-intrusive activities 0 to 5 ppm above Level D: No respiratory protection <br /> background required. <br /> 6 to 25 ppm Level C: Half- or full-face air-purifying <br /> respirator fitted with organic vapor <br /> filter cartridges. <br /> > 25 ppm Cease operations and evacuate work <br /> area. Contact Director of Health and <br /> Safety and Project Manager <br /> immediately. <br /> 11.0 CONTINGENCY PROCEDURES <br /> In the event of an emergency, site personnel will signal distress with three blasts of a <br /> horn (a vehicle horn will be sufficient), or other predetermined signal. Communication <br /> signals, such as hand signals, must be established where communication equipment is <br /> not feasible or in areas of loud noise. <br /> It is the SSO's duty to evaluate the seriousness of the situation and to notify appropriate <br /> authorities. Section 12 of this plan contains emergency telephone numbers as well as <br /> directions to the hospital. Nearby telephone access must be identified and available to <br /> communicate with local authorities. If a nearby telephone is not available, a cellular <br /> telephone will be maintained on site during work activities. <br /> Personnel should dial 911 in the event of an emergency. <br /> 11.1 Injury/Illness <br /> If an exposure or injury occurs, work will be temporarily halted until an assessment <br /> can be made of whether it is safe to continue work.
