-
Physically held in place by any means capable of preventing back-off or loosening of the closure by
impact or vibration during transportation.
-
Provided with a cap seal that is properly applied according to the cap seal manufacturer’s
recommendations. The cap seal must be capable of withstanding an internal pressure of at least 100 kPa
(15 psi).
-
Meet the following minimum thickness requirements:
-
If the capacity of the inner drum is less than or equal to 120 L (32 gallons) the minimum thickness of
the inner drum is: 1.3 mm (0.051 inches) for 1A1 and 1N1 drums, 3.9 mm (0.154 inches) for 1B1
drums, 3.16 mm (0.124 inches) for 1H1 drums, 1.58 mm (0.0622 inches) for the plastic inner container
and 0.96 mm (0.0378) for the outer steel drum of a 6HA1 drum.
-
If the capacity of the inner drum is greater than 120 L (32 gallons) the minimum thickness of the inner
drum is: 1.7 mm (0.067 inches) for 1A1 and 1N1 drums, 4.7 mm (0.185 inches) for 1B1 drums, 3.16
mm (0.124 inches) for 1H1 drums, 1.58 mm (0.0622 inches) for the plastic inner container and 1.08
mm (0.0378) for the outer steel drum of a 6HA1 drum.
-
Cushion the inner drum within the outer drum with a shock-mitigating, nonreactive material. There must
be a minimum of 5.0 cm (2 inches) of cushioning material between the outer surface (side) of the inner
drum and the inner surface (side) of the outer drum, and at least 7.6 cm (3 inches) of cushioning material
between the outer surface (top and bottom) of the inner drum and the inner surface (top and bottom) of the
outer drum.
A6.20.2.3. Pack in an inner packaging system that consists of an impact-resistant receptacle of glass, earthenware,
plastic, or metal securely cushioned with a nonreactive absorbent material. The package must be packed within a
leak-tight packaging of metal or plastic, then packed in a steel drum (1A2), aluminum drum (1B2), metal drum
(other than steel or aluminum (1N2)), plywood drum (1D), fiber drum (1G), plastic drum (1H2), wooden barrel
(2C2), steel jerrican (3A2), plastic jerrican (3H2), steel box (4A), aluminum box (4B), natural wood box (4C1 or
4C2), plywood box (4D), reconstituted wood box (4F), fiberboard box (4G), expanded plastic box (4H1), or solid
plastic box (4H2.) The capacity of the inner receptacle must not exceed 4 L (1 gallon). An inner receptacle that has
a closure, must have the closure held in place by any means capable of preventing backoff or loosening of the
closure by impact or vibration during transportation. Both the inner packaging system and the outer container must
each meet the test requirements of the PG I performance level independently. The total amount of liquid that can be
packed in the outer container must not exceed 16 L (4 gallons).
A6.21. Nitric Oxide. See 2.9 for additional requirements.
A6.21.1. Handling Instructions. Nitric oxide is extremely dangerous and poisonous. Wear an approved safety
mask and clothing when handling this material.
A6.21.2. Packaging Requirements. Pack nitric oxide in DOT 3A1800, 3AA1800, 3E1800, or 3AL1800 cylinders,
charged to a pressure of not more than 5,170 kPa (750 psi) at 21 degrees C (70 degrees F). Cylinders must be
equipped with a valve of stainless steel and a valve seat of material that is not deteriorated by contact with nitric
oxide or nitrogen dioxide. Cylinders or valves must not be equipped with safety devices (pressure relief) of any
type. Ensure valve outlets are sealed by a solid threaded cap or plug and an inert gasketing material. Each cylinder
must be cleaned as identified in 49 CFR, 173.337(c). Additionally:
A6.21.2.1. Pack cylinders, DOT 3E1800, in strong wooden boxes designed to protect valves from injury or
accidental functioning under conditions incident to transportation.
A6.21.2.2. Cylinders, DOT 3A, 3AA, and 3AL, must have their valves protected by metal caps, or other equally
protective guards, securely attached to the cylinders and be of sufficient strength to protect the valves from injury
during transit, or by packing in strong wooden boxes designed to protect valves from injury or accidental
functioning under conditions incident to transportation.
A6.22. Ethyl Methyl Ether. Each packaging must meet the requirements of the PG I performance level.
A6.22.1. Package items in combination packages consisting of glass, earthenware, plastic, metal receptacles, or
glass ampoules, then packed in steel drums (1A1 or 1A2), aluminum drums (1B1 or 1B2), metal drums other than
steel or aluminum (1N1 or 1N2), plywood drum (1D), fiber drum (1G), plastic drum (1H1 or 1H2), steel jerrican
(3A1 or 3A2), plastic jerrican (3H1 or 3H2), steel box (4A1 or 4A2), aluminum box (4B1 or 4B2), natural wood box
(4C1 or 4C2), plywood box (4D), reconstituted wood box (4F), fiberboard box (4G), expanded plastic box (4H1),
solid plastic box (4H2).
