2.4 Weatherproof and explosion proof lighting and ventilation switches shall be mounted on the prefabricated storage locker’s exterior wall next to the door with an exterior indicator light to show the ventilation system is on. Switches shall be mounted on the exterior wall on the doorknob side of the door within eight (8) inches of the doorknob allowing the lighting and ventilation to be easily turned on prior to opening the door. Vent and light switches shall be separate switches.

2.5 Electrical distribution panel single-phase, to be 3-wire, 120/240V, 60 AMP Load Center (NEMA 3R) with a main breaker and separate circuit breakers for the heater(s), vent system, and lighting, and one exterior 20 Amp GFCI outlet to be located on the exterior rear wall. Contractor shall install conduit and connections necessary to hook up to existing power on the site. The enclosure to be located on the back side of the New Prefabricated HAZMAT Storage Locker to keep it away from fuel dispensing that may occur in the front of the New Prefabricated HAZMAT Storage Locker. All electrical conduit, junction boxes, and panels boxes associated with the interior of the prefabricated storage locker’s electrical system shall be explosion proof. Explosion-proof switches and appurtenances are required.

Electrical connection in new prefabricated storage locker includes:

· Contractor to set (and connect) new electrical sub-panel.

2.6 Heating and ventilation shall be controlled manually by an adjustable explosion proof thermostat. The intake for exhaust ventilation shall be mounted no more than 12 inches above the bottom of the sump. Thermostat shall be initially set to automatically turn on the ventilation when the interior temperature reaches 80°F. Heat shall be initially set to automatically turn on when the interior temperature drops to 40°F. Heater shall be sized to maintain a minimum temperature of 50°F during winter conditions in Worland, Wyoming. The exterior vent switch shall “over-ride” the thermostat when turning on the ventilation system. When the ventilation switch is in the “off” position the thermostat shall control the system as described above.

2.7 Fresh air intakes shall be located just below the ceiling level on a different wall(s) than the exhaust fan. Intakes shall be a UL-listed fire damper design with removable insect screens that will allow the damper to close when exposed to fire. Fusible link to melt at 165ºF. Size the explosion proof mechanical ventilation and air intakes to provide six (6) air changes per hour and not less than 150 cubic feet per minute (CFM) of exhaust. Exhaust vent shall have louvered dampers that automatically open when the fan is in operation and close when the fan is off. Exhaust vents shall be equipped with a weather protective shroud. The exterior side of the intakes shall be equipment with hinged panels that can be positively latched in the closed position of over each intake in the winter and latch flat against the side of the building in the open position during the warmer times of the year.
