of the LEL for the substances contained in the tank AND less than 10% oxygen content of the measured atmosphere Note: at oxygen concentrations less than approximately 14%, the GasTech CGI/02 meter readings may become unreliable in the LEL mode. • Colorimetric Detector Tubes. Detector tubes sensitive to 0.5 ppm benzene in air will be employed on site as described in Section 4.3.2.

Site specific medical care facilities and emergency response contacts will be described in Section 6 of this plan. The forms provided in Section 6 must be fully completed for this plan to be authorized for use In addition, a map illustrating the route to the referenced hospital must be added to that section. Site personnel covered under this plan must be aware of the location on site of this information (eg SHSO's project vehicle) A first aid kit adequate for treating minor injuries and an appropriate eye wash device will be maintained by the SHSO in the project vehicle. Minor injuries incurred on site will initially be treated on site; professional medical attention may be sought as necessary at a later time Injuries of a more extensive nature will be transported to the referenced medical facility All injuries Rev 4/93 4-6 corp-h&slblankust h&s
