Sub-System Hazards Pre-Mitigation Mitigation Post-Mitigation

Probability

Severity

Risk Level

Probability

Severity

Risk Level

Training Not all mixers and loaders are adequately trained and qualified

Possible

Critical

High

Ensure that all personnel who will be loading aircraft are trained in hot loading procedures, with refresher each year. Provide simulation training for all mixers and loaders (agency and contractor) together throughout the season. Provide adequate briefings for all personnel prior to hot loading any aircraft.

Unlikely

Moderate

Medium

Base not approved for hot loading

Possible

Critical

High

Ensure base operations plan includes a supplement for hot loading of retardant and is approved at the appropriate level, refer to SABO. Ensure all personnel are trained on hot loading procedures.

Unlikely

Moderate

Medium

Unfamiliar with aircraft to be loaded

Likely

Critical

Extremely High

Specific type of aircraft will shut down prior to the first load at a new base each year. All personnel involved in the loading of aircraft will receive an orientation briefing for that aircraft to include proper hand signal use, and aircraft loading port valve connection and operation.

Possible

Negligible

Low

Aircraft Dangers of walking into turning propellers, or too close to jet engines

Likely

Catastrophic

Extremely High

Never walk through a propeller arc, even when engine is shut down. Do not walk under the wing at any time. Operate within the safety area around engines. Only load retardant on the side of the aircraft with non-running engines. Stay behind the wings of SEATs and S2s at all times. FWPT will be posted at front of aircraft where they can see all running engines, loaders, and aircrew.

Unlikely

Critical

Medium

High noise levels working near running engines

Almost Certain

Moderate

High

Only load aircraft on the side opposite running engines. All personnel should wear noise cancelling hearing protection while hot loading retardant. Only essential personnel allowed on the ramp during hot loading operations. Train on proper hand signals to be used during hot loading operations. Take breaks away from noise.

Unlikely

Critical

Medium

Velocity of exhaust/prop wash from running engines (thrust required for breakaway)

Likely

Moderate

High

Wear approved eye protection. Clear area before pilot takes engine out of ground idle. Ensure no one is behind engines when aircraft starts to move. Ensure Foreign Object Debris (FOD) walks occur on regular basis, so debris is not blown at personnel when aircraft starts moving. Secure loose objects within vicinity.

Unlikely

Negligible

Low

Aircraft can jump chocks while under ground idle

Possible

Critical

High

Pilot will remain at controls at all times during hot loading operations. FWPT will be positioned at front of aircraft during loading operations and maintain visual communication with both loaders and pilot.

Rare

Moderate

Medium

Heat from running engine(s)

Likely

Critical

High

Only load aircraft on the side opposite running engines. Only essential personnel on the ramp during hot loading operations. Train on proper hand signals to be used during hot loading operations. Operate within the safety area around engines. Take breaks away from heat.

Unlikely

Moderate

Medium

Human Factors Fatigue of ground personnel

Likely

Critical

Extremely High

Request additional staffing during times of high fire activity. Take breaks often, stay hydrated, ensure adequate rest facilities are available for all ground personnel. Ensure adequate rest between shifts.

Possible

Moderate

Medium

Heat stress

Likely

Critical

Extremely High

Utilize additional loaders/FWPTs during high activity. Recognize signs of heat stress at all levels and take action immediately. Stay hydrated, especially prior to beginning shift. Ensure adequate rest between shifts.

Unlikely

Moderate

Medium

Acceptance of high-risk activities as normal

Likely

Catastrophic

Extremely High

Emphasize importance of situational awareness as a means to recognizing risk. Provide risk management training for all personnel. Ensure thorough briefings/debriefings with special attention to risk management and preventing future accidents. Utilize risk assessments, JHAs, SMS, GARs etc. to assist in mitigating risk.

Unlikely

Catastrophic

High

Distracted personnel (aircrew, loaders, FWPT/RAMP)

Possible

Critical

High

Focus on task and identified role while hot loading.  Maintain situational awareness at all times. Do not distract others from their assigned task. Ensure communications are occurring at all phases of hot loading; use hand signals.

Unlikely

Critical

Medium

Incident Operations Subcommittee Updates the Next Generation Position Task Book for FFT1

Date:  May 7, 2026
Questions? 
Please contact: Incident Operations Subcommittee

The NWCG Incident Operations Subcommittee (IOSC) has updated the NWCG Position Task Book for Firefighter Type 1 (Squad Boss) (FFT1), PMS 311‑14. The FFT1 Position Task Book transitioned to the Next Generation (Next Gen PTB) format in June 2025 through the Incident Performance and Training Modernization effort. Since then, IOSC has received feedback from the wildland fire community regarding coding for one of the tasks. Task #13 has been updated to include the option of evaluation in a simulation.

See IOSC Memorandum 26‑01: Transition Plan for Implementation of Updates to the NWCG Position Task Book for Firefighter Type 1 (Squad Boss) (FFT1), PMS 311‑14 for more information.
