In the event of an engine induction fire while starting a reciprocating engine, what is the correct procedure?

In the context of an engine induction fire while starting a reciprocating engine, continuing to crank the engine can potentially extinguish the fire. This method works under the principle that cranking the engine creates an airflow through the induction system, which can help to draw the flames into the engine where the combustion process occurs. If conditions allow for efficient airflow, this can smother the flames, making it a feasible response to an induction fire.

However, it is critical to understand the risks associated with this response. This procedure must only be used when it's safe, such as in controlled environments and with trained personnel, as it can lead to a catastrophic situation if the fire worsens or if flammable materials are nearby.

Discontinuing cranking and summoning help is a cautious approach but may not address the immediate issue of the fire effectively. Pouring water on the engine can be dangerous due to the risk of spreading the flames or damaging the engine components, particularly with metal and internal engine parts. Utilizing a fire extinguisher is a standard procedure to combat any type of fire but may not directly resolve the issue of an induction fire during start-up.

Therefore, in specific scenarios, continuing to crank to attempt to extinguish the fire can be the most
