What is the appropriate action for a cold door fire procedure?

The appropriate action for a cold door fire procedure involves fully opening the door and using the extinguisher in a sweeping motion. This approach is based on the understanding that a cold door generally indicates that the fire is not directly on the other side, allowing for a safer way to address the situation. By fully opening the door, you maximize visibility and access to the fire while using the extinguisher to effectively cover the base of the fire. The sweeping motion helps to ensure the extinguishing agent spreads evenly over the flames, increasing the likelihood of extinguishing the fire efficiently.

It's critical to assess the temperature of the door before opening it; a cold door usually means that smoke and heat are not accumulating behind it, indicating a safer environment. This technique is effective in suppressing flames while minimizing the risk of exposure to the fire's heat and possible flashover.

Using a partially opened door might allow smoke and heat to escape but doesn’t provide sufficient access to ensure effective suppression. Keeping the door closed until notified would delay the response to the fire and could potentially allow the situation to worsen. Lastly, using the extinguisher through the closed door may not provide enough direct application of the extinguishing agent to the fire, making it less likely to be effective.
