Ventilation operations are based on two factors. Which are they?

• A. Strategy
• B. Building Construction
• C. Fire protection systems
• D. Weather conditions

Answer: (A)

Ventilation operations hinge on a clear plan for the incident. The main idea is that the decision to ventilate—and how to ventilate—rests on the strategy you adopt. Your strategy defines the objectives (such as removing heat and smoke to improve conditions for occupants and firefighters), dictates the method you’ll use (for example, whether to pursue vertical ventilation through a roof opening or another approach), and sets the sequence and timing of openings. Without a defined strategy, ventilation can be misapplied, potentially driving smoke and heat into safer areas, delaying rescue, or compromising the fire attack.

Other factors like building construction, fire protection systems, or weather can influence how you implement the plan, but they are inputs or constraints that the strategy must account for. They don’t replace the need for a sound strategy that guides the overall ventilation approach.
