Fires very rarely happen in motorsport but when they do, prompt, decisive action is vital, and this is one area above all where attending a training session is strongly recommended. You'll learn for example that it's standard practice to take an extinguisher to any incident just in case of a potential fuel leak. A car may have stopped because a fuel line has been severed and fuel is pouring out under the car.

The priority is to save life, then protect property. The most obvious danger to a competitor is burns, but fires consume oxygen and lack of this can result in brain damage r even death before a casualty is actually burnt.

The aim has to be to get to a burning vehicle and to have the fire under control - and preferably extinguished - within 30 seconds.

To put out a fire, know the type of extinguishers, what they'll cope with and how they work.

Then act as a team. Approach with the wind behind you to avoid smoke and powder getting blown in your face.

Stop about 10 to 12 feet away from the blaze to collect your thoughts and your colleagues. Don't get too close, as the power of the extinguisher could spread burning fuel.

If a competitor is trapped inside, the cockpit area takes top priority. If the competitor is out but on fire, get him or her on to the ground, pat and smother the flames or use an extinguisher. 

If the competitor is out and safe then concentrate on the seat of the fire.

Attack the flame at its base with a dry powder extinguisher, spray foam over the site to cool and seal it.

Don't cover your colleagues with flames, powder or foam. Don't run through flames - extinguish ground fires as you approach.

Watch out for flashbacks, under body fires, and fires in an engine bay or in the boot.

Once the flames are out, damp the car down and keep watching. Extinguishers are a must when clearing up a car that's been on fire.

Some rubber compounds and plastics which have been burnt can produce powerful acids which can cause severe injuries if you get them on your skin, so if you feel a burning sensation, go to a circuit Medical Centre or a Hospital Casualty Unit, and tell them you may have been in contact with acids produced by burnt rubber compounds.

Report the number and type of extinguishers you have used so that they can be replaced. Include partially used extinguishers in your tally and don't rely on them for use if there is a later fire.

Incidentally, if there's a fire or other major incident you may be approached by people - journalists or spectators - for your comments.

You should always refer them to Senior Officials on the event.
