When is it appropriate to begin exterior operations to protect exposures before interior entry?

• A. When conditions indicate risk to exposures and safe exterior access is available, and interior entry would add danger.
• B. Only after interior entry is completed.
• C. Only when the incident commander orders it.
• D. Only when there are no exposure risks.

Answer: (A)

Protecting exposures from a fire before entering interior spaces is a proactive tactic used when nearby structures or contents are at risk of ignition and you can safely work from the outside. If flames or radiant heat threaten a neighboring building or exposed fuel, exterior actions—like applying water from outside, creating distance barriers, or using shields to limit heat transfer—should begin as soon as you can access safely. This helps prevent the fire from spreading and gives interior crews time to operate with lower risk once they proceed. The trigger isn’t waiting for interior entry to start; it’s recognizing exposure risk and having a safe exterior approach. If there’s no exposure risk, exterior protection isn’t needed. While command input matters, the decision hinges on real-time assessment of exposures and safe exterior access.
