How should ground crews act to safely extinguish an airliner's brake unit fire? When the brake unit was overheated and had just begun to catch fire due to excessive braking because of long taxi distance upon arrival, the ground personnel (not firefighters) made the first intervention with the fire extinguisher on the parking stand until the firefighters arrive.

I’m wondering, are there any points to be taken into account in terms of ground safety when approaching landing gear during this first intervention or in the case of extinguishing? Is there any guidance procedure for ground crew other than professional firefighters?

What type of extinguisher content should be used to extinguish the fire?



Regarding the related post: How do fire crews handle hot brakes?

I don’t think it’s the same topic. I would like to know if there is a guidance document explaining how the ground crew [not fire crew] should behave in the event of a brake fire upon aircraft arrival.
Approach from upwind. The source of fire is hot brakes so apply maximum cooling, say water-based. But hydraulic fluids under pressure burn, so if brakes are engaged it's best to ensure with flight crew that the brakes are off as soon as the aircraft is stationary. Stay in the vehicle in case tyre ruptures; chances are it will go sideways. If fuel is leaking, use suitable foam.

I once saw a Harrier with a brake fire.  The burning pressurised brake fluid was acting like a flame thrower on the aircraft structure. The aircraft was written off. This happened about 1981.
