R R R R R R R R (b) Unless there is a fire, do not apply the extinguishing agent (liquid, water, mist, foam, etc.) with a spray gun on a hot tire if it is inflated. Do not apply the extinguishing agent directly into the heat pack of the brake or into the wheel. This can cause thermal shock to the stressed parts. Specially, do not use CO2 as this has a strong cooling effect which is not the same in all areas. It can cause an explosion in the stressed parts. Extinguishant on hot wheels can: - increase the time necessary for the fuse(s) to melt, or - prevent operation of the fuse(s). If the fuse plugs are not melted, you must let the brake get cool for at least one hour with no external cooling devices (you can use brake cooling fans, if installed).
R R NOTE : You can use blowers or air conditioning equipment only____ after: - the temperature of the fuses decreases (more than one hour after the aircraft stops) or - the fuses are melted. You must not use these if you can see flames or burning embers.
R R R (c) If there is a fire, immediately extinguish the fire. Do not wait until the tires are deflated. Come near the wheel only from the front or from the rear.
R R R R R NOTE : We recommend that you do not use multi-purpose powders, as____ they can be changed into solid or enameled deposit. These agents stop the fire but they decrease the heat dissipation speed. This can cause permanent structural damage at the brake, the wheel or wheel axle.
R R (d) Do not set the parking brake ON when "BRAKES HOT" warning is shown on the upper ECAM DU.
R R (e) Put a warning notice in the cockpit to tell persons not to operate the landing-gear control lever.
R R (f) If a tire is inflated, do not go near the area around the wheel for approximately one hour.
(g) Put the wheel chocks in position when there is no risk of tire burst.
(h) Clean all the parts if extinguishing agents were used.
