• • <br /> • A vehicle must be kept on-site when personnel are working, for the <br /> transport of slightly injured personnel to the hospital. Severely <br /> injured personnel MUST ONLY be transported by paramedics. <br /> 4.3.3 Respirator Usage <br /> The Project Consultant and/or the Project Managers' are responsible for <br /> deciding if respirator's should be used. Usage would be based on OVM <br /> measurements. The TLV concentrations as noted in § 4.1.2 should be <br /> used as the critical concentration. Since the OVM cannot differentiate <br /> between PCE, TCE or TCA, the total concentration of 54 ppm as <br /> detected on the OVM will trigger PPE modification. If concentrations of <br /> organic vapors in the ambient air (as measured by the OVM) exceed the <br /> TLV's the field personnel must move out of the area. If the <br /> concentration remains at or above the TLV for more than 5 minutes, the <br /> Project Consultant should be contacted and a decision made regarding <br /> whether to proceed with the work wearing respirators and extending the <br /> restricted work zone. <br /> Cartridges for the respirators must be replaced daily or when break- <br /> through occurs, whichever occurs first. <br /> Health and Safety Plan Page 8 <br />
