2.1.1 Environmental conditions.

2.1.1.1 Altitude. Unless otherwise specified (see 6.2), the vehicle, including the pumping system,

shall be designed for operation at 2,000 feet above sea level.

2.1.1.2 Temperature range. The tanker shall be capable of satisfactory storage and operation in

temperatures ranging from 0� to 125� F. The tanker shall be equipped with a winterization

system that extends the operational range of the tanker. The winterization system shall protect

the agent pump, agent piping systems, firefighting systems, and water tank to 0� F. It shall also

include the vehicle engine oil and coolant systems. While in operation, the appropriate systems

requiring winterization shall be powered by the tanker. While in storage, the winterization
