PITO PITO Battery Charging & Fueling Procedures 1 — Questions and Answers
Question 1: Why must ventilation be provided in a battery charging area for electric forklifts?
- To keep operators cool
- To disperse hydrogen gas released during charging (Correct answer)
- To reduce noise from chargers
- To meet building code for electrical rooms
Correct answer: To disperse hydrogen gas released during charging
Lead-acid batteries release hydrogen gas during charging, which is highly flammable and explosive if allowed to accumulate.
Question 2: Which class of fire extinguisher is appropriate for a battery acid spill that has ignited?
- Class A
- Class B
- Class C (Correct answer)
- Class D
Correct answer: Class C
Battery acid fires involving electrical equipment require a Class C extinguisher rated for energized electrical fires.
Question 3: Before connecting a charging cable to a forklift battery, the operator should first:
- Start the forklift to verify the battery is dead
- Turn off the charger (Correct answer)
- Check the battery water level
- Remove the battery from the forklift
Correct answer: Turn off the charger
The charger must be turned off before connecting or disconnecting cables to prevent dangerous electrical arcing.
Question 4: What personal protective equipment is required when adding water to a lead-acid forklift battery?
- Hard hat and steel-toed boots only
- Chemical splash goggles and acid-resistant gloves (Correct answer)
- High-visibility vest and ear protection
- Respirator and full-body suit
Correct answer: Chemical splash goggles and acid-resistant gloves
Battery acid (sulfuric acid) can cause severe chemical burns to eyes and skin, requiring splash goggles and acid-resistant gloves.
Question 5: When should distilled water be added to a lead-acid forklift battery?
- Before charging to dilute the acid
- After a full charge cycle is complete (Correct answer)
- Only when the battery fails to hold charge
- At the start of each shift regardless of charge level
Correct answer: After a full charge cycle is complete
Water should be added after a full charge because charging causes water to evaporate, and overfilling before charging can cause acid to overflow.
Question 6: Open flames and smoking are prohibited in battery charging areas because:
- OSHA requires non-smoking workplaces
- Hydrogen gas present during charging can ignite and explode (Correct answer)
- Charger equipment is sensitive to smoke
- Battery acid reacts with tobacco smoke
Correct answer: Hydrogen gas present during charging can ignite and explode
Hydrogen gas produced during battery charging is highly flammable and can be ignited by a spark, open flame, or cigarette.
