  • Cover batteries stored in boxes as sources of emergency power with a non-conductive rubber mat under the lid of the box.
  • Fit battery boxes with vents directed away from air inlets and sources of ignition.
  • During the change out of batteries, avoid naked flames and sparks in the immediate vicinity of the battery.
  • Chock batteries in their storage boxes to prevent movement under tow.
  • Do not lift batteries by their terminals.
  • Have plenty of ventilation, wear all required protective clothing and eyewear, remove jewelry, and exercise caution.
  • Specialty or non-conductive tools should be considered when performing maintenance on batteries.
  • Follow the manufacturer's instructions for testing, jumping, installing, and charging all batteries.
  • Only use spirit (alcohol) thermometers when measuring a battery's temperature.
