NFPA 1002 Driver/Operator - Aerial cheat sheet

Aerial types: aerial ladder (straight, rear- or mid-mount), elevating platform (articulating boom), water tower, and quint (pump, water tank, hose, ground ladders, aerial device).

NFPA 1901 requires a quint to carry 300 ft (90 m) of ground ladders, a minimum 300 gal (1,140 L) water tank, 850 gpm (3,200 L/min) pump, and 800 ft (240 m) of hose.

NFPA 1901 minimum aerial ladder: 50 ft (15 m) horizontal reach; typical straight ladders 75-110 ft, platforms 75-100 ft working height.

Aerial device load limits: tip load typically 250-750 lb (115-340 kg); the manufacturer's placard is the controlling value, not a rule of thumb.

Stabilizer spread is set by the manufacturer's load chart; full spread is required for maximum tip load and maximum extension.

Inspection items: turntable, boom sections, waterway, nozzles, rungs, rails, cables, hydraulic cylinders, pins, wear pads, ladder locks, and the aerial safety system.

NFPA 1911 governs in-service inspection, testing, and maintenance of fire apparatus, including annual and weekly checks.

Aerial device load test: NFPA 1911 requires a 200 lb (90 kg) test at the tip plus a 250 lb (115 kg) load at maximum extension for the structural test.

NFPA 1932 covers the use, care, and maintenance of ground ladders; NFPA 1911 covers apparatus-mounted aerial devices.

Daily/weekly check: fluid levels (engine oil, coolant, transmission, hydraulic oil, power steering), tire condition and pressure, belts, hoses, battery, lights, siren, and air brake system.

Air brake check: with engine off, the system should hold pressure; a loss greater than 3 psi/min (static) or 4 psi/min (with brakes applied) indicates a leak requiring repair.

Air compressor build-up: from 85 to 100 psi (586-689 kPa) in 45 seconds or less at fast idle for a typical system.

Hydraulic system: check reservoir level with the boom stowed per manufacturer; look for leaks at cylinders, fittings, and the PTO-driven pump.

Waterway and nozzle: inspect for cracks, corrosion, and blockage; drain and lubricate per manufacturer; verify the monitor and nozzle controls move freely.

Lubrication intervals follow the manufacturer's chassis and aerial lubrication chart; over-lubrication of cables and pins can attract grit.

Tire inspection: minimum tread depth 4/32 in (3 mm) on steering tires and 2/32 in (1.6 mm) elsewhere; check sidewalls for cuts, bulges, and weather cracking.

Record every check on the apparatus maintenance form; NFPA 1911 requires documentation of inspections, tests, and repairs.

Battery and charging: check electrolyte level on flooded batteries, terminal corrosion, and that the charging system maintains 13.8-14.5 V with the engine running.

Daily inspection form: list each item checked, condition found, corrective action, and the inspector's name, date, and time.

NFPA 1911 requires an annual performance test of the apparatus and aerial device; results are retained for the life of the vehicle.

Out-of-service criteria: any defect affecting safe operation (brakes, steering, aerial structural member, hydraulic leak, safety system) removes the apparatus from service until repaired.

Aerial device inspection levels per NFPA 1911: daily/weekly, monthly, annual, and a five-year load test.

Documentation must include the manufacturer's operational tests, load charts, and the most recent aerial test certificate carried on the apparatus.

Deficiency reporting: write the discrepancy, tag the apparatus out of service, and notify the officer and maintenance shop in writing.

Inspection records support liability defense and warranty claims; keep them retrievable by date and apparatus identification number.

Pre-trip inspection before every response: walk-around, lights, brakes, tires, fluids, aerial controls, stabilizers, and the PTO engagement.

Aerial apparatus has a high center of gravity and long rear overhang; swing wide on turns and watch the tail swing on the inside of the turn.

Stopping distance increases with weight; at highway speed allow at least a 4-second following distance, more in rain or on downgrades.

Use the engine brake or retarder on long downgrades; do not ride the service brakes, which can fade or overheat.

Height and length clearances: know the apparatus height with the boom stowed and the overall length including the rear step or ladder tip.

Backing requires a spotter at the rear; if no spotter is available, stop and get one - a backup camera does not replace a spotter.

Road speed with the aerial device deployed is zero; the aerial must be fully stowed and locked before the apparatus moves.

Weight distribution: keep the water tank and equipment loaded per the manufacturer; overloading reduces braking and stability.

PTO engagement must occur with the transmission in neutral or park, the parking brake set, and the apparatus stationary, per the manufacturer.

Position for the aerial tip to reach the objective with the boom at a safe angle; avoid operating near the maximum angle or full extension when possible.

Set the parking brake, chock the wheels, and engage the PTO before deploying stabilizers.

Deploy all stabilizers to the manufacturer's required spread; use pads or cribbing on soft ground to spread the load.

Check for overhead obstructions (power lines, trees, building overhangs) and underground hazards (vaults, septic tanks, utility lines) before setup.

Ground bearing pressure: a fully loaded outrigger can impose several thousand pounds per pad; soft soil may require cribbing or repositioning.

Maintain the minimum clearance from energized power lines per NFPA 70E and the manufacturer; treat all lines as energized until confirmed.

Level the apparatus within the manufacturer's tolerance (commonly 0-5 degrees) using the bubble level; the aerial's operating envelope depends on level.

Establish a collapse zone and scene control; the aerial tip and any raised equipment must stay clear of the fire building's collapse zone.

Spot the apparatus for the pump operator and aerial operator: the operator must see the tip and the objective, and communicate by radio or hand signals.

Only trained and authorized operators may operate the aerial device; NFPA 1002 requires demonstrated competency.

Pre-operation: verify the aerial safety system, boom locks, waterway valve, and that all personnel are clear of the boom's path.

Load the aerial per the manufacturer's tip load chart; account for tools, equipment, water in the pipe, and personnel (typically 250 lb per person).

Never move the apparatus with personnel on the aerial; never extend or rotate the boom into power lines or obstructions.

Use the aerial safety harness and belt, attach to the manufacturer-provided anchor, and keep the gate closed; do not stand on the top rung or rail.

Operate the aerial smoothly; avoid sudden starts and stops that shock-load the boom and can throw personnel off balance.

Emergency lowering: know the manual override or auxiliary pump procedure for lowering the boom if hydraulic power is lost.

Communication: the operator at the turntable and the person at the tip must maintain visual or radio contact at all times.

Cold-weather operation: warm the hydraulic oil, check for ice on rungs and the waterway, and follow the manufacturer's cold-weather limits.

Aerial waterway flow is typically 500-1,500 gpm (1,900-5,700 L/min) depending on the device; the master stream nozzle controls the pattern.

Pump pressure for an elevated master stream must overcome elevation: add 0.5 psi per foot of height (about 5 psi per 10 ft, or 1 bar per 10 m).

Aerial waterway friction loss is small compared with hose lays; the elevation head dominates the pump pressure calculation.

When supplying an aerial master stream, use large-diameter hose and a dedicated supply line; maintain at least 20 psi (1.4 bar) residual at the hydrant.

The pump operator must coordinate with the aerial operator before charging the waterway; trapped water in the pipe can freeze or burst it in cold weather.

Drain the aerial waterway after use and open the drain valve to prevent freeze damage; verify the nozzle is open to drain.

Fireground support: aerial apparatus supplies elevated master streams, ventilation access, rescue access, and water tower operations.

Relay or tanker operations: calculate required flow (gpm) times duration; a 1,000 gal tank at 500 gpm lasts 2 minutes without resupply.

Master stream reaction force: a 1,000 gpm stream at 80 psi produces substantial nozzle reaction; stabilize the apparatus and secure the monitor.

Emergency stop: release the controls, stop movement, and assess before resuming; never abandon the controls with the boom in motion.

Loss of hydraulic pressure: use the manual override or auxiliary pump to lower the boom and bring personnel down; follow the manufacturer's procedure.

Aerial device contact with power lines: stay in the bucket, warn others away, and do not touch the apparatus and ground simultaneously; call the utility.

Fire in the aerial or engine compartment: shut down the PTO, evacuate, and use the fixed suppression system or hand extinguishers from a safe distance.

Injury or fall from the aerial: stop operations, secure the scene, provide medical care, and preserve the scene for investigation.

Incident command: the aerial operator reports to the aerial officer or operations section chief; the apparatus officer retains control of the device.

Accountability: personnel on the aerial must be tracked by the incident accountability system; report entry and exit from the bucket.

Post-incident: complete the apparatus damage report, refuel, restock, and return the aerial to service only after inspection.

Rehabilitation and rotation: aerial operations are physically demanding; rotate operators and monitor for heat and fatigue.
