CONSOLIDATED CONSIGNMENTS

May contain any of the defined classes of dangerous goods.

CRYOGENIC (LIQUID)

Indicates refrigerated liquefied gases such as nitrogen, neon, helium, argon, etc. Cryogenic liquids are dangerous because they might destroy human skin tissue on contact, and when spilled, they could cause suffocation in confined spaces.

Diving lamps may contain rechargeable lead acid batteries, or other batteries (such as lithium) and high intensity diving lamps can generate extremely high heat when operated in air. In order to be carried safely, the bulb or battery must be disconnected.

ELECTRICAL EQUIPMENT / ELECTRONIC EQUIPMENT

May contain magnetized material or mercury in switch gear and electron tubes, wet batteries, lithium batteries or fuel cells or fuel cell cartridges that contain or have contained fuel.

ELECTRICALLY POWERED APPARATUS (WHEELCHAIRS, MOBILITY AIDS,LAWN MOWERS, GOLF CARTS, ETC.)

May contain wet batteries, lithium batteries or fuel cells or fuel cell cartridges that contain or have contained fuel.

EXPEDITIONARY EQUIPMENT

May contain explosives (flares), flammable liquids (gasoline), flammable gas (propane, camping gas) or other dangerous goods.

Film Crew or Media Equipment

May include explosive pyrotechnic devices, generators incorporating internal combustion engines, wet cell batteries, fuel and heat producing items.

Frozen Embryos / Food

May contain refrigerated liquefied gas or be packed in Carbon dioxide, solid (dry ice).

Fuel / Fuel Control Unit

May contain flammable liquids, flammable solids or flammable gases.

Hot Air Balloon

May contain cylinders with flammable gas, fire extinguishers, engines internal combustion batteries, etc.

HOUSEHOLD GOODS

May contain items meeting any of the criteria for dangerous goods including flammable liquids such as solvent based paint, adhesives, polishes, aerosols (for passengers, those not permitted under DGR 2.3), bleach, corrosive oven or drain cleaners, ammunition, matches, etc.

INSTRUMENTS

May conceal barometers, manometers, mercury switches, rectifier tubes, thermometers, etc. containing mercury.

LABORATORY TESTING EQUIPMENT

May contain items meeting any of the criteria for dangerous goods, particularly flammable liquids, flammable solids, oxidizers, organic peroxides, toxic or corrosive substances.

MACHINERY PARTS

May contain adhesives, paints, sealants, solvents, wet and lithium, Batteries, mercury, cylinders of compressed or liquefied gas, etc.

MAGNETS AND OTHER ITEMS OF SIMILAR MATERIAL

May individually or cumulatively meet the definition of magnetized material.

MEDICAL SUPPLIES

May contain items meeting any of the criteria for dangerous goods, particularly flammable liquids, flammable solids, oxidizers, organic peroxides, toxic or corrosive substances or lithium batteries.

METAL CONSTRUCTION MATERIAL /METAL PIPING/ METAL FENCING

May contain ferro-magnetic material, which may be subject to special stowage requirements due to the possibility of affecting aircraft instruments.

PASSENGER BAGGAGE

May contain items meeting any of the criteria for dangerous goods. Examples include fireworks, flammable household liquids, corrosive oven or drain cleaners, flammable gas or liquid lighter refills or camping stove cylinders, matches, ammunition, bleach, aerosols (those not permitted under DGR 2.3), etc.

PHARMACEUTICALS

May contain items meeting any of the criteria for dangerous goods, particularly radioactive material, flammable liquids, flammable solids, oxidizers, organic peroxides, toxic or corrosive substances.

PHOTOGRAPHIC SUPPLIES

May contain items meeting any of the criteria for dangerous goods, particularly heat producing devices, flammable liquids, flammable solids, oxidizers, organic peroxides, toxic or corrosive substances or lithium batteries.

RACING CAR OR MOTORCYCLE TEAM EQUIPMENT

May contain engines, carburettors or fuel tanks which contain fuel or residual fuel, flammable aerosols, cylinders of compressed gases, nitromethane, other fuel additives or wet batteries, lithium batteries, etc.
