How do offensive and defensive strategies differ in terms of occupancy and risk?

• A. Offensive involves entering to control and extinguish; defensive confines the fire from outside to protect exposures when conditions are unsafe for interior attack.
• B. They are identical in occupancy and risk.
• C. Offensive avoids any interior entry and focuses on venting only.
• D. Offensive attack only concerns ventilation.

Answer: (A)

When deciding how to fight a fire, the chosen tactic hinges on occupant likelihood and firefighter safety. An offensive approach means entering the building to locate and rescue occupants if possible and to directly control and extinguish the fire from the inside. This is chosen when occupants are at risk but the conditions inside allow a reasonably safe interior attack—things like structure stability, access, visibility, and heat levels are workable.

A defensive approach switches the focus to the exterior, keeping firefighters outside to confine the fire and protect exposures. This is used when interior conditions are unsafe or the risk to firefighters or occupants is too high—heavy fire, potential collapse, poor access, or when occupants have already evacuated or rescue isn’t feasible—so the priority becomes stopping spread and protecting surrounding property rather than interior fire suppression.

Options that imply there’s no difference between strategies, that focus only on venting, or that ignore interior attacks miss the core decision about risk and occupancy. The best choice clearly contrasts entering to control and extinguish with staying outside to confine and protect when interior work would be too risky.
