Study Notes

Fire Response Priorities

  • Consider rescue, fire attack, and water supply; standpipes are useful for structures over four stories.
  • Second Engine Company ensures water supply, assists hoseline advancement, controls doors, and deploys an additional hoseline.
  • First and second Engine Companies focus on fire attack and establish standby teams while communicating via radio.

Occupant Rescue vs. Occupant Removal

  • Immediate rescues are critical for occupants in danger, especially on balconies or windows; these resources impact suppression capabilities.
  • Rescue scenarios involve occupants close to the fire who may need immediate assistance to avoid hazardous conditions.
  • Removal scenarios apply to occupants safe behind a closed door, advised to "Protect in Place" until resources arrive; exceptions exist when attic fires threaten upper floors.

Commercial Building Characteristics

  • Commercial buildings vary from small to large, using different construction materials, including wood, masonry, steel, and concrete.
  • They may be standalone or part of a commercial district; types include big box stores, strip malls, and high-rises.
  • Fires may burn deep inside these structures, making them hard to locate and access due to limited entry points and potential remodeling hazards.

Tactics for Commercial Fires

  • Essential tactics include locating, confining, and extinguishing fires, similar to residential firefighting, but with limited window access and long distances to exits.
  • Use ropes for safety when not on a hoseline, particularly in unknown storage areas with high fire loads.
  • Evaluate conditions using ADULTS criteria; applying 2.5" hoselines effectively cools large fires and requires coordination between two companies.
  • Coordinate horizontal and vertical ventilation through available windows or doors to support hoseline advancement.

Ventilation Techniques

  • Open roof scuttles, skylights, and hatches alongside vertical ventilation to improve airflow.
  • Assign both Ladder Companies to ventilation tasks at commercial structures.

Movement Within Structures

  • Avoid movement exceeding 175' without secondary access points to manage air quality and ensure safe egress, especially with high piled stock present.

Resource Additions

  • Engine (5th) should identify the need for a secondary water source and report to the Incident Commander (IC) for assignment.
  • Aerial (2nd) must position itself advantageously and report to the C Side Supervisor or IC for task assignment.
