Final answer:
If a brush fire cannot be contained by the first alarm, command should scale up the response with additional resources and personnel, and implement strategies like creating fire lines and mobilizing air support while coordinating inter-agency efforts and informing the public.
Step-by-step explanation:
When a brush fire cannot be contained by first alarm responses, command should escalate the situation according to established emergency protocols. This typically involves requesting additional resources through a second or greater alarm, which can include more firefighting personnel, specialized equipment, and support from nearby regions or even the state or federal level. The incident commander will assess the situation and make decisions on evacuations, road closures, and inter-agency coordination.
Key strategies include creating fire lines to control the spread of the fire, utilizing air support if available, and protecting structures and civilians in the path of the fire. Ongoing communication with the public and media is also essential to ensure safety and disseminate information.
