When charging a lead-acid forklift battery, what safety action must be taken first?
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.
What gas is released by lead-acid batteries during the charging process that creates a fire hazard?
Answer: Hydrogen
Lead-acid batteries emit hydrogen gas during charging, which is highly flammable and can explode if ignited.
What is the minimum recommended ventilation requirement for a battery charging area?
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.
How should an operator handle a battery that shows cracks or leaking electrolyte?
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.
What type of water should be added to a lead-acid forklift battery to maintain electrolyte levels?
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.
An electric forklift battery should NOT be charged if its state of charge is above what percentage?
Answer: 80%
Opportunity charging above 80% state of charge is generally discouraged as it can shorten battery life through increased heat generation.
