Forklift certification Certification Forklift certification Refueling and Recharging Procedures 3 — Questions and Answers
Question 1: What is the primary hazard when charging an electric forklift battery?
- Excessive noise
- Hydrogen gas released during charging (Correct answer)
- Radiation exposure
- Carbon monoxide buildup
Correct answer: Hydrogen gas released during charging
Lead-acid batteries emit flammable hydrogen gas while charging, which can ignite.
Question 2: Why must the charging area be well ventilated?
- To keep operators cool
- To disperse hydrogen gas and prevent explosive buildup (Correct answer)
- To dry the floor faster
- To reduce battery weight
Correct answer: To disperse hydrogen gas and prevent explosive buildup
Ventilation prevents flammable hydrogen from accumulating to dangerous levels.
Question 3: What should be prohibited in the battery charging area?
- Wearing gloves
- Open flames, smoking, and sparks (Correct answer)
- Using a fire extinguisher
- Reading the manual
Correct answer: Open flames, smoking, and sparks
Any ignition source can set off the hydrogen gas, so flames, sparks, and smoking are banned.
Question 4: When connecting a charger to a battery, what is the correct sequence?
- Turn charger on, then connect
- Connect the battery first, then turn the charger on (Correct answer)
- It does not matter
- Connect while the forklift is running
Correct answer: Connect the battery first, then turn the charger on
Connecting before energizing the charger prevents arcing sparks at the connector.
Question 5: What PPE is recommended when handling or watering lead-acid batteries?
- Sandals and a t-shirt
- Acid-resistant gloves, face shield, and apron (Correct answer)
- Only a hard hat
- Hearing protection only
Correct answer: Acid-resistant gloves, face shield, and apron
Battery electrolyte is corrosive sulfuric acid, so acid-resistant gear protects skin and eyes.
Question 6: Where should emergency eyewash and neutralizing supplies be located?
- In the manager's office
- In or near the battery charging/handling area (Correct answer)
- Locked in a storage cabinet offsite
- They are not required
Correct answer: In or near the battery charging/handling area
OSHA requires eyewash and acid-neutralizing facilities be readily accessible where batteries are charged or changed.
Question 7: When adding water to a lead-acid battery, when should it be done?
- Before charging when plates are exposed
- After charging is complete, filling to the proper level (Correct answer)
- While the forklift is operating
- Water should never be added
Correct answer: After charging is complete, filling to the proper level
Watering after charging avoids overflow, since electrolyte expands and rises during the charge cycle.
