Hydrogen Gas

Flammable hydrogen gas is always present during battery recharging.

Industrial Lift Truck Operation

Hydrogen gas is potentially explosive if allowed to accumulate in a closed area. Below are requirements and recommended best practices to prevent injuries from hydrogen gas:

  • Post no smoking signs.
  • Use non-sparking tools.
  • Prevent open flames, sparks, or electrical arcs in the battery charging area to minimize the danger of explosion.
  • Provide adequate ventilation.
  • Open the battery cover when charging so the hydrogen gas can vent better. This is especially important in confined areas where the danger of accumulation is greatest.
