A7.3.22. MIL-D-23119 500-gallon capacity collapsible fabric drums authorized under 3.7. Five hundred (500)
gallon fabric drums shipped on other than tactical/contingency/emergency missions must be drained to the greatest
extent possible.
A7.3.23. Bulk storage tanks completely drained according to paragraph 3.7.2.
A7.4. Refrigerating Machine. A refrigerating machine assembled for shipment and containing 7 kg (15 pounds)
or less of flammable liquid for operation in a strong, tight receptacle is excepted from specification packaging,
marking, and labeling except for the PSN of the flammable liquid.
A7.5. Aircraft Hydraulic Power Unit Fuel Tank.
A7.5.1. Handling Instructions. In the event of a leak during transportation of hydrazine, crew members should
use their aircraft oxygen masks in a positive pressure mode.
A7.5.2. Packaging Requirements. Aircraft hydraulic power unit fuel tanks containing a mixture of anhydrous
hydrazine and monomethyl hydrazine (M86 fuel) and designed for installation as complete units in aircraft are
excepted from specification packaging requirements if the units comply with one of the following:
-
The unit must consist of an aluminum pressure vessel made from tubing and having welded heads. Primary
containment of the fuel within this vessel must consist of a welded aluminum bladder having a maximum
internal volume of 46 L (12 gallons). The outer vessel must have a minimum design gauge pressure of
1.275 kPa (185 psi) and a minimum burst gauge pressure of 2.755 kPa (400 psi). Each vessel must be leak-
checked during manufacture and before shipment and must be found leak proof. The complete inner unit
must be securely packed in noncombustible cushioning material, in a strong outer tightly closed metal
packaging that will adequately protect all fittings. The maximum quantity of fuel per unit and package is
42 L (11 gallons).
-
The unit must consist of an aluminum pressure vessel. Primary containment of the fuel within this vessel
must consist of a welded hermetically sealed fuel compartment with an elastomeric bladder having a
maximum internal volume of 46 L (12 gallons). The pressure vessel must have a minimum design gauge
pressure of 5.17 kPa (750 psi). Each vessel must be leak-checked during manufacture and before shipment
and must be found leak proof. The complete inner unit must be securely packed in noncombustible
cushioning material, in a strong outer tightly closed metal packaging that will adequately protect all fittings.
The maximum quantity of fuel per unit and package is 42 L (11 gallons).
A7.6. Packaging for Class 3 Materials, Poisonous by Inhalation (Hazard Zone A or B). Package Class 3
materials with an Inhalation Hazard (Hazard Zone A and B) as follows:
A7.6.1. Package in DOT specification cylinders as identified in 49 CFR, part 178, subpart C, except that
specification 8, 8AL, and 39 cylinders are not authorized. Cylinders must also meet the requirements of A3.3.2.
A7.6.2. Pack in an inner drum (1A1, 1B1, 1N1, 1H1, or 6HA1), then place in an outer drum (1A2 or 1H2). Both
the inner and outer drum must be tested to the PG I performance level. The outer 1A2 drum must have a minimum
thickness of 1.35 mm (0.053 inches). The outer 1H2 drum must have a minimum thickness of 6.30 mm (0.248
inches). The capacity of the inner drum (1A1, 1B1, or 1N1) must not exceed 220 L (58 gallons). The inner drum
must also meet the following requirements:
-
Satisfactorily withstand a hydrostatic pressure test (as outlined in 49 CFR, paragraph 178.605) of 550 kPa
(80 psig).
-
Satisfactorily withstand a leak proof test (as outlined in 49 CFR, 178.604) using an internal air pressure at
55 degrees C (131 degrees F) of at least twice the vapor pressure of the material to be packaged.
- Have screw-type closures that meet all the following requirements:
-
Closed and tightened to a torque as prescribed by the closure manufacturer, using a device that is
capable of measuring torque.
-
Physically held in place by any means capable of preventing backoff 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:
