NFPA 1003 ARFF common mistakes

NFPA 1003 ARFF · Understand the traps and how to avoid them.

Mistake 1

Uses ten-codes or department-specific radio codes during the initial report and omits the location until the end of the transmission.

Candidates carry over habits from structural fire or law-enforcement radio traffic and assume local codes are understood airport-wide.

What to do instead

Use plain language and the standard order: unit identifier, exact location (runway/taxiway designator plus grid coordinate), nature of emergency, and action taken. Announce 'emergency traffic' when the channel must be cleared.

Mistake 2

Reads the airport grid map by counting from the wrong corner and reports a gate number or terminal name instead of the grid coordinate, sending the response to the wrong taxiway.

Grid maps are rarely practiced outside a tabletop exercise, so candidates default to familiar landmark descriptions.

What to do instead

Practice converting a point on the airfield diagram to a grid reference and back until it is automatic. In the initial report, give both the runway/taxiway designator and the grid coordinate.

Mistake 3

Treats all aircraft as if fuel were carried only in the wings, and cannot say where fuel will pool after a gear collapse or a wing-root fire on a wide-body transport.

Study is based on a generic three-view diagram rather than type-specific fuel-system layouts.

What to do instead

Study the fuel-tank layout for the aircraft based at the airport, using the aircraft rescue and firefighting chart. Note center-wing tanks, horizontal-stabilizer tanks, fuel-dump ports, and where fuel flows when a wing is breached.

Mistake 4

Charges the line with dry chemical only and does not follow with AFFF, then reports the fire as extinguished.

Dry chemical produces a fast visible flame knockdown, which candidates mistake for final extinguishment.

What to do instead

Dry chemical does not cool the fuel or seal vapours. Follow with AFFF to establish a blanket, cool the area, and prevent reignition, and continue until the fuel source is secured.

Mistake 5

Fails to distinguish foam concentrate from finished foam solution and misstates the apparatus foam tank capacity or proportioning setting.

The terms are used loosely in training material and candidates memorise tank sizes without linking them to the proportioner.

What to do instead

Memorise tank capacity in concentrate, the rated proportioning percentage, and the resulting duration of foam flow. Check the proportioner setting before charging the line.

Mistake 6

Sets the proportioner to 3% for every incident without checking the concentrate label or whether the product is rated differently for the fuel involved.

3% is the most familiar number, so it becomes a default rather than a deliberate selection.

What to do instead

Read the concentrate label and the proportioner setting before charging. Match the percentage to the manufacturer's rating for the fuel and to the recommended application rate.

Mistake 7

Stops foam application as soon as visible flame disappears, allowing the fire to reignite from hot metal or an unsecured fuel source.

Flame-out is mistaken for a secured scene, and crews are eager to move to rescue or overhaul.

What to do instead

Maintain the foam blanket and continue application until the fuel source is isolated and hot metal is cooled. Re-apply after any disturbance of the blanket and keep a backup line charged.

Mistake 8

Cuts through a wing spar, pressurised strut, or hydraulic line while opening the fuselage for extrication.

Candidates apply structural-extrication habits from vehicles and do not consult aircraft-specific cut zones.

What to do instead

Use the aircraft rescue chart and manufacturer's emergency response guide. Identify the no-cut zones before operating, and cut only at designated points away from spars, struts, and pressurised lines.

Mistake 9

Commits the first-arriving ARFF vehicle to an offensive interior attack on a large external fuel fire instead of a defensive master-stream attack to cool the fuselage and support rescue.

Structural firefighting instincts favour an interior attack, and the rescue priority is not applied as a sequence.

What to do instead

Sequence the attack as rescue path, fuselage cooling, then extinguishment. Use turret or master stream on large fuel fires; reserve interior attack for a contained cabin fire with a viable rescue.

Mistake 10

Assumes the senior ARFF officer automatically becomes Incident Commander and ignores the unified command structure set out in the airport emergency plan.

Fire-service rank habits override the plan, and the airport emergency plan is treated as a document for administrators rather than responders.

What to do instead

Know that the plan defines roles and that unified command includes airport operations, EMS, and law enforcement. The ARFF officer may be a sector commander rather than the IC; confirm command at the first arriving unit.
