When deciding between offensive and defensive exterior tactics, focus on the overall safety and goals of the incident by evaluating key conditions on scene. The fire extent shows how large and active it is and whether interior suppression might still be possible or would be overwhelmed. Structural integrity tells you if the building can support safe interior operations or if collapse risk makes entry untenable. Location of occupants matters for life safety—whether people are likely inside and where they are relative to the fire and entry points. Water supply determines if you can sustain an interior attack or if you’re forced to rely on exterior methods to control the blaze. Exposure risk looks at nearby structures, hazards, and the potential for the fire to spread, which can push you toward protecting exposures rather than pressing inside.

If these factors indicate that occupants may be inside and the building is structurally sound enough to allow controlled interior work with adequate resources, an offensive approach aimed at extinguishment and rescue can be appropriate. If the fire is widespread, the structure is compromised, occupants are uncertain or unreachable, water supply is uncertain, or exposures are at high risk, defensive exterior tactics become the safer course to shield crews and protect surrounding properties.

Other factors like the color of the building or the time of day don’t determine the tactic by themselves, and while ladder availability can influence feasibility, it doesn’t replace the need to base the decision on these core conditions.
