Sec. 173.334  Organic phosphates mixed with compressed gas.

    Hexaethyl tetraphosphate, parathion, tetraethyl dithio 
pyrophosphate, tetraethyl pyrophosphate, or other Division 6.1 organic 
phosphates (including a compound or mixture), may be mixed with a non-
flammable compressed gas. This mixture may not contain more than 20 
percent by weight of organic phosphate and must be packaged in DOT 
3A240, 3AA240, 3B240, 4A240, 4B240, 4BA240, or 4BW240 cylinders meeting 
all of the following requirements:
    (a) Each cylinder may be filled with not more than 5 kg (11.0 lb) of 
the mixture, to a maximum filling density of not more than 80 percent of 
the water capacity.
    (b) No cylinder may be equipped with an education tube or a fusible 
plug.
    (c) No cylinder may be equipped with any valve unless the valve is a 
type approved by the Associate Administrator.
    (d) Cylinders must be overpacked in a box, crate, or other strong 
outside packaging conforming to the requirements of Sec. 173.25 and 
arranged to protect each valve or other closing device from damage. 
Except as provided in paragraph (e) of this section, no more than four 
cylinders may be packed in a strong outside packaging. Each strong 
outside packaging with its closing device protection must be 
sufficiently strong to protect all parts of each cylinder from 
deformation or leakage if the completed package is dropped 1.8 m (6 
feet) onto a non-yielding surface, such as concrete or steel, impacting 
at the packaging's weakest point.
    (e) Cylinders may be packed in strong wooden boxes with valves or 
other closing devices protected from damage, with not more than twelve 
cylinders in one outside wooden box. An outer fiberboard box may be used 
when not more than four such cylinders are to be shipped in one 
packaging. Valves must be adequately protected. Box and valve protection 
must be of sufficient strength to protect all parts of inner packagings 
and valves from deformation or breakage resulting from a drop of at 
least 1.8 m (6 feet) onto a non-yielding surface, such as concrete or 
steel, impacting at the weakest point.
