Extinguishing vehicle fires
Guidelines for Rescue Services, smart, 2006 Page 7
Overview
Extinguish fires in accordance with the guidelines of the professional fire services!
Body:
Magnesium is increasingly being used in safety
relevant reinforcement structures in the body.
For example, the instrument panel structure in
smart vehicles is made of magnesium.
When combatting fires within the vehicle's inte
rior and in the area around the instrument panel,
it is therefore vital to observe the special
instructions issued by the fire department with
respect to the materials employed in these areas!
i Magnesium is a Class D flammable material
according to the EN2 European Standard on
"flammable materials of various kinds".
Restraint systems:
If a fire breaks out inside the vehicle, it may acti
vate any untriggered front airbags, sidebags and
windowbags or the pyrotechnical emergency
tensioning retractors.
Gas generators are designed to ignite as soon as
the temperature inside the gas generator
reaches 160 180° C.In such cases the ignition
squib and the solid fuel burn without destroying
the gas generator. During combustion a specific
volume of gas is released at a specific pressure.
i When the front airbags, sidebags,
windowbags and emergency tensioning
retractors are triggered, controlled
combustion takes place. The components do not
explode.
Windowbags
The gas generators of the windowbags are filled
not with solid fuel, but with compressed gas.
i The compressed gas generators of the
windowbags must not be cut, as otherwise the
compressed gas may suddenly escape!
i Before cutting the corresponding body
panels the inner paneling of the A, B or C pillars
must be removed using a suitable tool and the
exact installation location of the gas generators
determined!
