Attachment 6
CLASS 2--COMPRESSED GASES
A6.1. General Requirements. This attachment contains information concerning the packaging and general
handling instructions for Class 2.1 (flammable gas), Class 2.2 (nonflammable, nontoxic compressed gas), and Class
2.3 (toxic gas).
A6.2. General Handling Instructions for Compressed Gases.
-
Store compressed gases in a cool, ventilated area away from fire hazards, sources of heat, ignition, or
sparks.
-
When stored in an upright position, secure cylinders to fixed supports. Compressed gas cylinders may be
palletized for shipment provided the valves are protected and cylinders are adequately secured to the pallet.
-
Exercise care when handling compressed gases. Do not drop, jar, or slide cylinders since the gas may be
toxic or asphyxiating. Personnel must know the importance of handling compressed gases properly.
-
Ensure valves are always tightly closed and protected before offering for transportation.
HA6.3. Aerosols. Prepare aerosols meeting the definition of “Consumer Commodity as authorized under
paragraph A13.4.” Package aerosol products identified under the proper shipping name “Aerosols” as follows:
A6.3.1. For an aerosol containing non-toxic substances, pack in inner non-refillable non-metal receptacles not
exceeding 120 mL (4 fluid-ounce) capacity each, or in inner non-refillable metal or plastic receptacles not exceeding
1 L (34 fluid-ounces) provided all of the following conditions are met:
-
Pressure in the aerosol container must not exceed 1245 kPa at 55 degrees C (180 psig at 130 degrees F) and
each receptacle must be capable of withstanding without bursting a pressure of at least 1.5 times the
equilibrium pressure of the contents at 55 degrees C (130 degrees F).
-
If the pressure exceeds 970 kPa at 55 degrees C (140 psig at 130 degrees F) but does not exceed 1105 kPa
at 55 degrees C (160 psig at 130 degrees F) use a DOT 2P, IP7, IP7A, or IP7B inner metal receptacle. If
the pressure exceeds 1105 kPa at 55 degrees C (160 psig at 130 degrees F) but does not exceed 1245 kPa at
55 degrees C (180 psig at 130 degrees F) use a DOT 2Q, IP7A, or IP7B inner metal receptacle.
-
Liquid content of the material and the gas must not completely fill the receptacle at 55 degrees C (130
degrees F).
-
Each aerosol exceeding 120 mL (4 fluid ounce) capacity must have been heated until the pressure in the
aerosol is equivalent to the equilibrium pressure of the content at 55 degrees C (130 degrees F) without
evidence of leakage, distortion, or other defects.
-
Protect the valves by a cap or other suitable means.
-
Tightly pack aerosols in a strong outer packaging capable of meeting packaging performance test outlined
in A19.3.4. The complete package must not exceed 30 kg (66 lbs) gross weight.
A6.3.2. For an aerosol containing toxic substances, pack in inner non-refillable non-metal receptacles not exceeding
120 mL (4 fluid ounce) capacity each, or in inner non-refillable metal receptacles not exceeding 1 L (34 fluid
ounces) provided all of the following conditions are met:
-
Pressure in the aerosol container must not exceed 1500 kPa at 55 degrees C (217 psig at 130 degrees F) and
each receptacle must be capable of withstanding without bursting a pressure of at least 1.5 times the
equilibrium pressure of the contents at 55 degrees C (130 degrees F).
-
If the pressure exceeds 970 kPa at 55 degrees C (140 psig at 130 degrees F) but does not exceed 1105 kPa
at 55 degrees C (160 psig at 130 degrees F) use a DOT 2P, IP7, IP7A, or IP7B inner metal receptacle. If
the pressure exceeds 1105 kPa at 55 degrees C (160 psig at 130 degrees F) but does not exceed 1245 kPa at
55 degrees C (180 psig at 130 degrees F) use a DOT 2Q, IP7A, or IP7B inner metal receptacle. If the
pressure exceeds 1245 kPa at 55 degrees C (180 psig at 130 degrees F) but does not exceed 1500 kPa at 55
degrees C (217 psig at 130 degrees F) use an IP7B inner metal receptacle.
-
Liquid content of the material and the gas must not completely fill the receptacle at 55 degrees C (130
degrees F).
-
Each aerosol exceeding 120 mL (4 fluid ounce) capacity must have been heated until the pressure in the
aerosol is equivalent to the equilibrium pressure of the contents at 55 degrees C (130 degrees F) without
evidence of leakage, distortion, or other defects.
