When charging electric GSE batteries, which safety practice is most important?
Answer: Charge only in a well-ventilated area away from sparks and open flames
Lead-acid batteries release hydrogen gas while charging, which can explode if it builds up near an ignition source.
What PPE is required when checking or adding water to a lead-acid GSE battery?
Answer: Safety glasses or face shield and acid-resistant gloves
Battery electrolyte is sulfuric acid, so eye and hand protection is needed to prevent chemical burns.
A tug's brakes feel soft and the vehicle rolls when stopped on a slight incline. What should the operator do?
Answer: Stop using the tug, tag it out of service and report the brake defect
Brake defects are critical safety issues, and the unit must be removed from service right away.
Before maintenance personnel work on a diesel GSE engine, what should be done first?
Answer: Shut down the engine, remove the key and apply lockout/tagout
Lockout/tagout prevents accidental startup that could injure the technician.
Where should fuel spills from GSE refueling on the ramp be reported?
Answer: To the airport operations or fire department per the station spill procedure
Fuel spills must be reported under airport spill procedures so they are contained and cleaned to prevent fire and environmental harm.
Which condition on a belt loader belt requires removing the unit from service?
Answer: The belt is torn, frayed or has missing cleats
Torn or frayed belts can catch clothing, drop bags, or create FOD, so the unit must be repaired first.
Why is a 'brake check' done when first driving GSE away from the parking area?
Answer: To confirm the brakes work before approaching aircraft or people
A brake test before entering active areas confirms the vehicle can stop safely near aircraft.
