BULKHEAD
- Transportation and transfilling compartments must be separated from the driving compartment by a bulkhead to prevent buildup of an oxygen-enriched atmosphere in the driver's compartment. Fixed windows are permitted.
TRUCK BODY
- Multiple vents should be provided in the cargo compartment. At minimum, there should be one vent on the forward portion of each side of the cargo compartment and one in the rear. Vents should be at or near the floor line. At a minimum, the total natural ventilation must provide 1 square foot per 300 square feet of compartment ceiling area.
NO COMBUSTIBLE MATERIAL
- such as paneling, plywood, or carpet- should be used to finish the cargo compartment.
VESSELS VENT OUTSIDE
- Any vessels permanently installed in the vehicle must have all safety and vessel-vent discharge lines piped outside the vehicle. These vents must be designed so that they are not likely to discharge onto oil or asphalt surfaces or other combustible material, or into the vehicle's exhaust system. If they discharge upward, they should have weather protection. Vessels not permanently installed in the vehicle should be suitably restrained during transit to prevent them from moving or tipping over.
PIPING
- All fittings and piping should be installed with material compatible for the service pressures and temperatures involved and acceptable for oxygen service.
TRAINING
- No vessel should be filled without an adequately trained person in attendance.
NO FILLING IN MOTION
- No vessel should be filled while the vehicle is in motion or while the engine is running.
FILLING IN TRUCK
- When any vessel is filled inside the cargo compartment, all cargo compartment doors should be open and vent gas should be directed outside. When a vessel is filled outside the vehicle, it should be positioned to avoid vented liquid or gas coming into contact with asphalt or other combustible material.
BEFORE STARTING ENGINE
- After filling, all transfer lines should be properly drained, and oxygen vapors allowed to disperse before the vehicle's engine is started.
SIGNS
- Notices prohibiting smoking and open flames must be clearly posted at appropriate locations in the compartment and on the outside of the vehicle.
PLACARDS
- Vehicles and containers must be marked, placarded and labeled. In the United States, this must be done in accordance with Title 49 of the Code of Federal Regulations and all other federal, state and municipal regulations. In Canada, this must be done in accordance with the regulations of Transport Canada and all other federal, provincial and municipal regulations .
