Spare batteries must be individually protected so as to prevent short circuits and carried in carry-on baggage only. In addition, each spare battery must not exceed the following quantities:

For lithium metal or lithium alloy batteries, a lithium content of not more than 2 grams; or
For lithium ion batteries, an aggregate equivalent lithium content of not more than 8 grams.

Heat producing articles:  With the approval of the air operator(s), passenger may bring heat-producing articles (e.g. battery-operated equipment such as underwater lamps and soldering equipment, which if accidentally activated, will generate extreme heat and can cause fire) in carry-on baggage only. The heat producing component, or the energy source, must be removed so as to prevent unintentional functioning during transport.

Medicinal or toilet articles:  Passengers may bring non-radioactive medicinal or toilet articles (including aerosols), such as hair sprays, perfumes, colognes, insect repellents or medicines containing alcohol. They may also bring aerosols that are for sporting or home use and that carry no flammable or toxic risk, in checked baggage only.

Mercurial barometer and thermometers:  With the approval of the operator(s), a representative of a government weather bureau or similar official agency may bring a mercurial barometer or mercurial thermometer, as carry-on baggage only. The barometer or thermometer must be packed in a strong outer packaging, having a sealed inner liner or a bag of strong leak-proof, puncture-resistant material impervious to mercury, which will prevent the escape of mercury from the package irrespective of its position. The pilot-in-command must be informed of the barometer or thermometer.

Medical or clinical thermometers:  Passengers may bring one small medical or clinical thermometer, which contains mercury, for personal use, when in its protective case.

Portable electronic devices:  Passengers may bring portable electronic devices (for example cameras, cellular phones, laptop computers and camcorders) powered by fuel cell systems, and spare fuel cartridges, under the following conditions:

3. fuel cell cartridges must not be refillable by the user. Refuelling of fuel cell systems is not permitted except that the installation of a spare cartridge is allowed. Fuel cell cartridges which are used to refill fuel cell systems but which are not designed or intended to remain installed (fuel cell refills) are not permitted to be carried;
4. the maximum quantity of fuel in any fuel cell cartridge must not exceed:
1. for liquids 200 mL;
2. for liquefied gases, 120 mL for non-metallic fuel cell cartridges or 200 ml for metal fuel cell cartridges;
5. each fuel cell cartridge must be marked with a manufacturer’s certification that it conforms to IEC PAS 62282-6-1 Ed. 1, and with the maximum quantity and type of fuel in the cartridge;
6. each fuel cell system must conform to IEC PAS 62282-6-1 Ed. 1, and must be marked with a manufacturer’s certification that it conforms to the specification;
7. no more than two spare fuel cell cartridges may be carried by a passenger;
8. fuel cell systems containing fuel and fuel cell cartridges including spare cartridges are permitted in carry-on baggage only;

Wheelchairs or other battery-powered mobility aids with non-spillable batteries:  With the approval of the operator(s), passengers may bring wheelchairs or other battery-powered mobility aids with non-spillable batteries (see Packing Instruction 806 and Special Provision A67), as checked baggage provided the battery terminals are protected from short circuits and the battery is securely attached to the wheelchair or mobility aid;

Wheelchairs or other battery-powered mobility aids with spillable batteries:  With approval of the operator(s), passengers may bring wheelchairs or other battery-powered mobility aids with spillable batteries as checked baggage, provided that the wheelchair or mobility aid can always be loaded, stowed, secured and unloaded in an upright position. The battery must be disconnected, the battery terminals protected from short circuits and the battery is securely attached to the wheelchair or mobility aid. If the wheelchair or mobility aid cannot be loaded, stowed, secured and unloaded always in an upright position, the battery must be removed and the wheelchair or mobility aid may then be carried as checked baggage without restriction. The removed battery must be carried in strong, rigid packaging as follows.

The packaging must be leak-tight, impervious to battery fluid and be protected against upset by securing it to a pallet or in a cargo compartment appropriately secured (other than by bracing with freight or baggage) such as by use of restraining straps, brackets or holders;

Batteries must be protected against short circuits, secured upright in the packaging and surrounded by compatible absorbent material sufficient to absorb their total liquid contents; and

The packaging must be marked 'Battery, wet, with wheelchair' or 'Battery, wet with mobility aid' and labelled with a 'Corrosive' label and with a package orientation label.

The pilot-in-command must be informed of the location of a wheelchair or mobility aid with and installed battery or the location of a packed battery.

It is recommended that passengers make advance arrangements with each operator. As well, spillable batteries should be fitted, where feasible, with spill-resistant vent caps.
