BACKGROUNDER TRANSPORT CANADA’S
COMPREHENSIVE APPROACH TO AIRCRAFT FIRE SAFETY
Canada has one of the safest air transportation systems in the world.
This system operates on the principle that, both in the air and on the
ground, safety is a shared responsibility between all parties involved
- regulators, manufacturers and operators.
Aircraft fire safety is a key aspect of Transport Canada’s safety
responsibilities. Specifically, it is responsible for the development,
implementation and enforcement of safety standards and regulations under
the Canadian Aviation Regulations.
Fire safety on-board aircraft involves complex issues that require
international cooperation between regulators, manufacturers and operators.
Transport Canada works actively with partner authorities, particularly the
U.S. Federal Aviation Administration (FAA) and the European Joint Aviation
Authorities, along with industry at home and from around the world, both
directly and within recognized international working groups and
committees, to address pertinent issues. Examples of such groups include
the FAA’s International Aircraft Materials Fire Test Working Group and
International Aircraft Systems Fire Protection Working Group, as well as
the Aging Transport System Rulemaking Advisory Committee.
Canadian design certification standards include several measures to
minimize the likelihood of on-board fires and to counteract fires in areas
that have been identified to be most vulnerable, such as engines, cargo
compartments and lavatories. These measures are based on a thorough
assessment of fire risks and conditions. The standards require the
provision of fire/smoke detection systems and suppression/extinguishing
systems, the isolation of ignition sources and the means to prevent,
through design, the accumulation of flammable fluids and vapors.
Transport Canada’s progress on significant fire safety improvements has
focused on the following areas:
- stringent flammability and fire resistance standards for seat
cushions and cabin interior materials to extend evacuation time, for
escape slides to augment their resistance to radiant heat from fires and
for cargo compartments to contain possible fires;
- cabin floor emergency lighting systems to provide guidance to exits
in smoke conditions;
- improved on-board fire fighting equipment to enhance in-flight fire
fighting; and
- fire detection and extinguishing and suppression systems for
lavatories and for cargo compartments that are not accessible in flight.
Transport Canada is also working with other regulatory authorities to
improve standards for other materials and technologies. This work
includes:
- developing improved flammability criteria for hidden materials such
as wiring - expected to be completed this year - to reduce their
propensity for ignition and flame propagation;
- investigating new technologies and systems which can mitigate the
risk of ignition, such as arc-fault interrupters;
- reviewing fire risks and conditions in various hidden areas and
investigating means to provide enhanced detection and suppression in
such areas; and
- developing advanced fire-resistant materials.
Transport Canada is committed to taking appropriate action to protect
the travelling public and will continue to work with the international
community to achieve a consensus on air transportation safety that
reflects the concerns of the department and the Transportation Safety
Board.
