HAPSITE ER Operating Manual
Although the airline will carry the box of canisters in the same cargo hold as the
baggage, they will not accept hazardous materials at the check-in counter. Take the
box of canisters with the form filled out to the desk of your airline at the air freight
terminal at your airport. They will be able to assist you with transporting the gas.
C.3 Empty Canisters
It is important to remember that it is the pressure of the gas in the canisters which
is considered hazardous. The gases themselves are mostly Nitrogen. (The amount
of the organic Internal Standards compounds is 50 ppm and 100 ppm).
To discard the canisters, simply discharge them outdoors by inserting any small
point into the valve. Once they are empty, they can be disposed of as aluminum
scrap.
WARNING
When discharging the canisters, point them away from
people and stand upwind of the discharge. Whenever
possible discharge canisters into a hood.
If the empty canisters cannot be recycled or disposed, they may be shipped back
to their point of origin for disposal:
Be certain that they are empty (less than 30 psi) then package them in a plain
cardboard box, without any green diamond label. Mark the box as "Empty
Canisters for Destruction". Ship them, prepaid, to
