30 CFR 57.11053(d) Fire fighting plan. <br />In the event of an underground mine fire, several methods can be used to fight the fire, depending on the <br />circumstances. It is important to understand that the mine is presently naturally ventilated, and will have <br />mechanical ventilation when work is begun underground. In both cases, the ventilation drift is the air <br />intake, and the main portal entry is the exhaust for the mine. <br />In the event of a mine fire, ventilation will continue until all underground personnel have evacuated the <br />mine and have been accounted for. If all personnel have been accounted for, then two methods of fighting <br />the fire can be pursued, depending on the circumstances: <br />1) At this point, the mine ventilation may be stopped by closing off the air intake at the fan bulkhead <br />in the ventilation drift. This will involve shutting down the fan and covering the intake opening. <br />Additionally the Mine Portal can be covered. This will starve the fire of combustion air. <br />2) If it decided that the mine fire is to be investigated and ultimately fought, mechanical ventilation <br />will be left on, fire fighting personal ( with proper PPE and fire fighting equipment) will enter the <br />mine from the ventilation drift, keeping the supply air at their backs as they enter the mine and <br />assess the situation. <br />If personnel remain in the mine, then mine ventilation will remain on, and step (2) followed to allow <br />entry into the mine to search for unaccounted for mine personal. <br />30 CFR 57.11053 (e) Surface Procedure to follow in an emergency. <br />In the event of an emergency, the on -site Chevron construction coordinator shall notify Chevron's Hiner <br />Gate Operations Control Room either by site radio, cell phone, or by local land line phone located at the <br />nearest well pad. The Operations Control Room personal will notify the local DeBeque Colorado Fire <br />Rescue department and they will respond. <br />In the event of an outside emergency, such as brush fire, inclement weather, etc. all mine personnel shall <br />evacuate the mine site to a safe mustering point as directed by the Chevron Construction coordinator. <br />30 CFR 57.11053 (0 Availability of Emergency Communication and Transportation Facilities. <br />Emergency communications and transportation will be provided by the DeBeque, Colorado Fire and <br />Rescue Department, which will be contacted through the Chevron Hiner Gate Operations Control. <br />
