Which statement is true regarding the operation of exhaust fans during a fire emergency?

The statement that exhaust fans are not required to shut down during a fire emergency is accurate because the operation of these fans depends on their specific functions and the fire protection strategy in place. In certain situations, exhaust fans might assist in ventilating smoke and harmful gases from the environment, thereby improving visibility and preventing smoke from spreading to other areas.

For example, if exhaust fans are implemented in a controlled manner, they can help maintain a safer environment by expelling smoke and heat. This capability can be a vital component of a comprehensive fire protection system. Such fans can help mitigate the effects of a fire, supporting the safety of both occupants and emergency responders.

In contrast, while some systems may allow for remote control of exhaust fans or designate that they should remain operational depending on various factors, the requirement and effectiveness of keeping them running are determined by the specific fire scenario and the established emergency protocols. This validation ensures they contribute positively to fire safety measures rather than exacerbating the situation.
