16.5 Battery Charging

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.
