What is required to be provided when the SOP specifies active cooling is to be implemented?

• A. Exhaust fan
• B. Ventilation fan
• C. Water mist
• D. Heat lamp

Answer: (B)

Active cooling relies on moving air to remove heat buildup around the team and equipment. A ventilation fan provides the necessary airflow to exchange hot air with cooler ambient air, which directly lowers temperatures and reduces heat stress during the rescue. This is why the ventilation fan is the best choice for implementing active cooling.

An exhaust fan moves air out of a space but doesn’t guarantee a steady supply of cooler air and proper venting on its own, so it doesn’t strictly meet the stated requirement. A water mist can cool by evaporation, but it’s a different cooling method and depends on water supply and conditions. A heat lamp would add heat, not remove it, so it clearly doesn’t fit active cooling.
