Study Notes
Fireground Strategy
- The Incident Commander is responsible for the fireground strategy
- Two main strategies are considered: Offensive and Defensive
- The strategy can change with conditions or as benchmarks are met
- The initial Incident Commander must communicate the strategy in the on-scene report.
- The strategy is determined by several factors including the building, fire load, smoke and fire conditions, and rescue potential
Offensive Fire Attack
- The structure must be determined as safe to enter before an offensive fire attack is initiated
- Offensive fire attacks are centered on rescue
- The first attack line must be placed between the victims and the fire for safety purposes
- Fire conditions need to be assessed before starting fire operations
- Command must consider the direction and speed of fire extension, particularly as it might affect:
- Rescue activities
- Risk to firefighters
- Confinement efforts
- Exposure protection
- Command needs to allocate personnel and resources based on these factors
- Command must consider all "sides" of the fire (front, rear, sides, top, bottom, and interior) to consider fire control
- In concealed spaces (attics) ventilation and fire streams to these areas needs to be a priority
- Command must anticipate the fire spread to ensure resources are ready
- The attack should focus on securing exposures and protecting property that might be at risk
- Attack variables include:
- Location and position of the attack
- Size of the attack
- Support functions needed
Marginal Fire Attack
- A marginal fire attack is conducted for rescue purposes
- If offensive conditions are not clear, Command may initiate an offensive interior attack while setting up defensive positions on the exterior
- Interior attacks are closely monitored and abandoned if necessary
- A marginal attack should be abandoned when
- A primary "all clear" has been obtained and the situation remains marginal
- The roof is unsafe or untenable
- Interior forces encounter excessive heat and cannot locate or make progress on the fire
- Heavy smoke is being forced from the building under pressure and increasing
- Assigning a Roof Sector early is crucial for evaluating roof conditions and the safety of interior operations
- It is better to switch to a defensive strategy too soon rather than too late
Defensive Fire Attack
- A defensive strategy is used when offensive operations are deemed unsafe due to personnel safety concerns and the structure is considered lost
- Defensive strategies are announced as Emergency Traffic and all personnel must withdraw from the structure maintaining a safe distance
- A PAR (Personnel Accountability Report) must be conducted after changing from an offensive to a defensive strategy
- Interior lines are withdrawn and repositioned when using a defensive strategy
- Hose lines should be abandoned if withdrawing from a structure is delayed and unsafe
- The top priorities of defensive operations are:
- Personnel safety
- Exposure protection
- Master streams are the most effective tactic to be employed in defensive operations
- "Fire under control" means the forward progress of the fire has been stopped and the remaining fire can be extinguished with available resources
- A PAR report must be conducted after the fire is brought under control
- If the situation requires a defensive strategy from the start, Command will inform dispatch that a primary search will not be completed, however, all buildings should be searched when possible after the initial fire is controlled
