SAFETY
PRECAUTIONS FOR LIQUID
OXYGEN DELIVERY IN VANS OR TRUCKS
A)
Truck Body
The cargo compartment needs to have a minimum of two vents
in the forward portion of the cargo area and two in the rear
portion. Vents need to be as close to the floor line as possible.
At a minimum, the total natural ventilation must provide 1
square foot per 300 square feet of compartment ceiling area.
B)
Bulkhead
The drivers
compartment must be separated from the transfilling and cargo
areas to prevent a buildup of oxygen enriched atmosphere from
entering the drivers area. Fixed windows are permitted.
C)
Non-Acceptable Materials For the Cargo Area
No combustible
materials such as paneling, plywood, or carpet should be used
in the cargo area. Diamond plating is advised
D)
Ooutside Ventilation
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 vehicles 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.
E)
Piping
All piping
and fittings should be installed with material compatible
for the service pressures and temperatures involved and acceptable
for oxygen service.
F)
Personnel
Vessels
should be filled by trained personnel only.
G)
Filling in Vehicle
When
filling inside the cargo area, all doors should be opened
and vent gas should be directed outside. Vessels should not
be filled when the vehicle is in motion or when engine is
running. When vessels are filled outside of vehicle, precautions
should be taken to avoid any liquid or gas coming into contact
with asphalt or other combustible material.
H)
Before Starting Engine
Drain
all transfer lines and allow oxygen vapors to disperse before
starting engine of vehicle.
I)
Signs
Clearly
post signs inside and outside the vehicle prohibiting smoking
and open flames.
J)
Placards
In the
United States vehicles and containers must be marked, placarded
and labeled in accordance with TITLE 49 of the Code of Federal
Regulations and all other federal, state and municipal regulations.
In Canada this must comply with the regulations of Transport
Canada.
