Level of Action<br />
Below 10% Continue Operation<br />
Above 10% Stop work, re-evaluate;<br />
consult FHSR <strong>and</strong> take<br />
appropriate corrective action,<br />
as determined by PM (i.e.<br />
ventilate boreholes <strong>and</strong><br />
excavations ⎯ displace<br />
combustible gas with inert<br />
gas ⎯ dry ice pellets)<br />
11.3 CALIBRATION AND RECORDKEEPING<br />
The PID will be calibrated to 100 ppm isobutylene prior to use daily in accordance with the<br />
manufacturer’s specification. Personal sampling pumps will be calibrated with a primary flow<br />
meter (i.e. Gillibrator, Bio Flowmeter) prior to <strong>and</strong> after use. The operation of the PID <strong>and</strong> all<br />
personal sampling equipment will be used in accordance with manufacturer’s specifications.<br />
Equipment calibration will be recorded in the calibration log kept with the instrument <strong>and</strong> in the<br />
field notebook. Air monitoring results will be recorded in the field notebook.<br />
