Study Notes
- Firefighters must experience nozzle reaction force during training to handle it safely.
- Nozzle reaction force increases with flow and nozzle pressure.
- Some nozzles are designed to reduce nozzle reaction force or have devices to assist in controlling the hose line.
- Standpipe pressure can be significantly lower than those provided by a fire department pumper.
- NFPA 14 requires a sign to be posted stating the location, flow, and pressure of the two most hydraulically remote hose connections.
- Standpipe systems must be inspected and tested regularly.
- Aerial apparatus can be used as portable standpipes.
- Using a rope to advance a fire line to an upper floor is a time-consuming and complex tactic.
- The standard attack hose line is the first action in an offensive attack.
- When more than two 1¾-in. hose lines are needed to control the main body of fire, there is an obvious need for 2½-in. hose lines.
- Selecting the right nozzle type is important for effective firefighting
- Solid-stream nozzles may be more effective than fog streams
- Large-orifice/large-drop sprinklers have better extinguishing qualities
- Automatic variable-stream nozzles can provide both solid and variable streams
- Indirect attacks are limited in application and can be dangerous to occupants and firefighters
- Direct attacks are preferred in most situations where conditions permit
- Softening the target tactic involves applying water to the fire prior to making entry
- Proper ventilation is critical to prevent flashover and make interior conditions tenable
- Softening the target tactic may not be applicable in some situations
- Firefighter safety is a priority and should be considered in all tactics and strategies.
- The UL research on the "soften the target" tactic has been misinterpreted as an SOP to apply water to a fire as soon as possible from the safest location.
- The critical point is to apply water only if there is visible fire.
- The soften the target tactic is effective for fires rapidly growing toward flashover or in temporary decay waiting for fresh air.
- This method cannot be advocated or denounced as it may be ineffective under certain circumstances.
- The tactic may be extended to larger compartments, but results may vary.
- Larger compartments have more air space and available oxygen.
- Fire growth necessary to involve a large compartment could take longer than in residential occupancies.
- Small fires in large open areas may remain confined to a limited area.
- The method has merit but should be used with caution.
- The UL research applies only to fires with visible flames or heavy and/or pushing smoke conditions.
