16.5 Battery Charging

Print Page

Lead acid batteries contain corrosive liquids and also generate Hydrogen gas during charging which poses an explosion hazard. The following guidelines should be followed for battery charging areas:

  • A “No smoking” sign should be posted. 
  • Before working, remove all jewelry from hands and arms and any dangling jewelry to prevent accidental contact with battery connections (this can cause sparks which can ignite vapors). 
  • Always wear appropriate PPE such as rubber or synthetic aprons, splash goggles (ideally in combination with a face shield), and thick Neoprene, Viton, or Butyl gloves. 
  • A plumbed emergency eyewash station must be readily available near the station (please note, hand held eyewash bottles do not meet this criteria.) 
  • A class B rated fire extinguisher needs to be readily available. If none is available, contact EHS at 607-255-8200. 
  • Ensure there is adequate ventilation available to prevent the buildup of potentially flammable and explosive gases. 
  • Keep all ignition sources away from the area. 
  • Stand clear of batteries while charging. 
  • Keep vent caps tight and level. 
  • Only use the appropriate equipment for charging. 
  • Store unused batteries in secondary containment to prevent spills. 
  • Have an acid spill kit available. The waste from a spill may contain lead and neutralized wastes may be toxic. Contact EHS at 607-255-8200 for hazardous waste disposal. 
  • Properly dispose of your used batteries.
