CFA CFA Battery & Electric Forklift Safety 1 — Questions and Answers
Question 1: When charging a lead-acid forklift battery, what safety action must be taken first?
- Turn off the charger before connecting or disconnecting the battery (Correct answer)
- Add distilled water before starting the charge
- Check the battery voltage with a multimeter
- Remove the battery from the forklift and store it outdoors
Correct answer: Turn off the charger before connecting or disconnecting the battery
The charger must always be turned off before connecting or disconnecting a battery to prevent dangerous electrical arcing.
Question 2: What gas is released by lead-acid batteries during the charging process that creates a fire hazard?
- Carbon monoxide
- Nitrogen dioxide
- Hydrogen (Correct answer)
- Methane
Correct answer: Hydrogen
Lead-acid batteries emit hydrogen gas during charging, which is highly flammable and can explode if ignited.
Question 3: What is the minimum recommended ventilation requirement for a battery charging area?
- No special ventilation is required if the room is large
- Adequate airflow to prevent accumulation of explosive hydrogen gas (Correct answer)
- A single exhaust fan running once per shift
- Open windows on at least one side of the building
Correct answer: Adequate airflow to prevent accumulation of explosive hydrogen gas
OSHA requires battery charging areas to have adequate ventilation to prevent hydrogen gas from accumulating to explosive concentrations.
Question 4: How should an operator handle a battery that shows cracks or leaking electrolyte?
- Continue using it until the next scheduled maintenance
- Tape the crack and monitor for further leakage
- Remove the battery from service immediately and report it (Correct answer)
- Add extra distilled water to dilute the leaking acid
Correct answer: Remove the battery from service immediately and report it
A cracked or leaking battery is a serious safety hazard and must be taken out of service immediately and reported to a supervisor.
Question 5: What type of water should be added to a lead-acid forklift battery to maintain electrolyte levels?
- Tap water
- Softened water
- Distilled water (Correct answer)
- Filtered well water
Correct answer: Distilled water
Only distilled water should be added to lead-acid batteries because minerals in other water types contaminate the electrolyte and reduce battery life.
Question 6: An electric forklift battery should NOT be charged if its state of charge is above what percentage?
- 20%
- 30%
- 50%
- 80% (Correct answer)
Correct answer: 80%
Opportunity charging above 80% state of charge is generally discouraged as it can shorten battery life through increased heat generation.
