4.2 Attack Techniques by Fire Location (JPR 5.3.2)

4.2 Attack Techniques by Fire Location (JPR 5.3.2)

Quick Answer: Fire location dictates attack technique. Grade-level fires call for direct interior advance with backup line protection; upper-floor fires require stairwell protection and standpipe supply; basement fires demand flow-path awareness and often exterior access; attic fires require confinement and coordination before pushing into confined overhead spaces. The Firefighter II selects the technique, briefs the team, and communicates the plan to Command.

NFPA 1001 JPR 5.3.2 explicitly requires attack techniques matched to the level of the fire: attic, grade level, upper levels, or basement. The written exam and practical skill sheets test whether candidates can identify the correct tactic—not merely whether they can hold a nozzle. The coordinating Firefighter II announces the technique during the entry briefing and adjusts if size-up reveals a different fire level than initially reported.

Grade-Level (First-Floor) Interior Attack

Grade-level fires are the most straightforward interior attack scenario when entry is on the same level as the fire. The coordinating officer selects the shortest protected path from the entry door to the fire compartment.

Standard Grade-Level Technique

1. Stretch and charge the primary attack line (typically 1.75-inch preconnect) before entry.
2. Stretch a backup line to the entry point covering the primary line's path and protecting against extension above or behind the attack team.
3. Control the entry door—crack open only after the line is charged and the team is ready; limit uncontrolled air introduction.
4. Advance to the seat using a coordinated push: nozzle, backup, and officer move together.
5. Apply water at the ceiling level to cool the thermal layer, then direct the stream at the base of fire once the compartment is cooled.

Communication Points

The coordinator tells Command: entry door location, line length deployed, fire compartment identified (kitchen, living room, garage), and whether the team is pushing direct or holding at the doorway for a brief exterior cool-down (transitional attack) before full entry.

Upper-Floor Attack and Standpipe Operations

Upper-floor fires introduce vertical travel, increased hose friction, and the critical need for reliable water supply at elevation. Multi-story occupancies equipped with standpipe systems are a staple of Firefighter II skills testing.

Stairwell Advance Principles

• Protect the stairwell: The attack team uses the stairwell as the primary hose route but must not allow fire to involve the stairwell itself—this is the building's egress for search teams and other companies.
• Stay on the same side of the stairwell as the hose bend when turning corners to prevent kinks.
• Door control at the fire floor: Open the fire-floor door only when the line is charged and the team is positioned; uncontrolled opening can draw fire into the stairwell.

Standpipe Connection Procedure (Skills Sheet Core)

Standpipe operations follow a standardized sequence tested on Pro Board and state practical exams:

Hose Bundles and Extended Stretch

When standpipes are absent or inoperable, departments deploy hose bundles carried up stairwells or hoisted via rope and tool bags. The coordinator communicates to Command how many lengths are needed and whether additional companies must bring supplemental bundles.

Upper-Floor Communication

Report to Command: standpipe outlet location (floor and stairwell), line size connected, water confirmed at outlet, fire apartment or unit number, and whether the stairwell is clear for other companies.

Basement and Below-Grade Attack

Basement fires present inverted flow-path challenges: heat and smoke rise toward the entry point at grade level, often creating intense conditions at the top of interior basement stairs.

Technique Selection

• Exterior access preferred: Bilco doors, walk-out basement doors, or below-grade windows allow horizontal attack and keep the team off the interior stairwell chimney.
• Interior stairwell attack: If no exterior access exists, the team advances down the stairs with a charged line, cooling the thermal layer above before descending, with a backup line at the top of the stairs.
• Flow path awareness: Opening the basement door at grade without water ready pulls fire and hot gases up the stairwell toward the entry team.

Coordination Requirements

The Firefighter II communicates ventilation requirements to Command (not unilateral roof cutting)—basement fires often need coordinated exhaust at grade level or horizontal openings before aggressive interior descent. Report hazards such as cluttered stairs, lightweight floor assemblies over the fire, or reports of occupants trapped below.

Attic Fire Attack

Attic fires occur in confined, low-clearance spaces with limited escape routes and rapid horizontal extension along roof trusses and cocklofts.

Offensive vs. Defensive Attic Considerations

• Offensive push: Feasible when access is via a scuttle or pull-down stair and the fire is localized; the team advances a short line, applies water in short bursts to avoid steam expansion in the confined space, and withdraws before ceiling collapse.
• Confinement: Close attic access doors to limit extension while exterior crews or coordinated ventilation requests relieve pressure.
• Defensive transition: Brown or black smoke from eaves, sagging roof decking, or truss involvement may require the coordinator to request a mode change and pull the team out.

Communication

Report attic access location, whether the fire is vent-limited or fuel-limited from the coordinator's vantage, extension into adjoining units, and any request for roof-group coordination or secondary line to protect the floor below.

Selecting and Communicating the Technique

The Firefighter II does not silently choose a tactic. JPR 5.3.2 requires that attack techniques are communicated to the attack teams. Use plain language at the door:

• "Grade-level push through side Alpha, kitchen fire, backup line to side Alpha door."
• "Standpipe on floor two, stairwell Bravo, apartment 2B, 1.75 attack with backup at the outlet."
• "Basement fire, exterior Bilco access on side Charlie, no interior stair entry."
• "Attic fire above bedroom two, short offensive push through hall scuttle, confine if heat does not drop in 60 seconds."

Matching technique to fire level—and ensuring every team member and the IC hear the plan—is the core competency of this JPR.
