Which is the correct procedure during an O-VEIS operation?

During an O-VEIS (Objective, Ventilation, Entry, Isolation, Search) operation, the primary focus is on conducting a quick and effective search for victims while also managing ventilation and isolating the fire as needed.

Closing the door of the search room as soon as possible is a critical aspect of this procedure. Doing so helps to contain smoke and heat within the affected area, which is vital for maintaining a safer environment for both victims and firefighters. It not only minimizes the spread of fire and smoke to other areas but also allows firefighters to work more effectively in a controlled environment where visibility and conditions can be better managed. This action is essential to preserve the air quality and thermal conditions in the space where the search is being conducted.

By contrast, leaving doors open for ventilation can lead to hazards such as increased fire spread and compromised visibility. Opening windows to cool a room can also destabilize conditions and potentially worsen fire behavior. Checking for victims before closing the door is important, but immediate action to close the door afterward ensures a protective environment for those still inside while maintaining operational safety.
