How should Halon/CO2 be sprayed into doors for external fire?

Spraying Halon or CO2 for external fires is a technique that prioritizes safety and effectiveness. The recommended method involves using the stick horn halfway in and upwind, which helps ensure that the agent is directed into the fire while minimizing the risk of smoke or flames being blown back toward the operator.

This method allows the extinguishing agent to approach the fire effectively while the operator remains at a safe distance, reducing exposure to heat and toxic gases. Being upwind is crucial for avoiding the hazardous fumes produced by the fire, as well as for enhancing the chances of the agent reaching the flames directly instead of being dissipated or deflected away.

In contrast, directing the foam or agent directly into the flames can pose significant safety risks, such as a flashback or inadequate extinguishing coverage. Additionally, approaching from a distance of 10 feet is not typically safe or effective, as this may allow the fire to grow or spread before the agent can effectively make contact. Standing at the front of the aircraft does not account for wind direction or positioning for optimal extinguishment; therefore, it is less effective and potentially more dangerous.
