  • Converting Occupational Exposure Limits from mg m³ to ppm
    How do I convert mg m 3 to ppm at different temperatures and pressures? Back to top The number 24 45 in the equations above is the volume (litres) of a mole (gram molecular weight) of a gas or vapour when the pressure is at 1 atmosphere (760 torr or 760 mm Hg) and at 25°C
  • CCOHS: Garages - Batteries - Canadian Centre for Occupational Health . . .
    Lead-acid batteries can produce explosive gasses The vent caps allow these gasses to escape during charging Batteries should only be handled in well-ventilated areas by trained and authorized personnel When talking about lead-acid batteries, people usually call sulfuric acid "battery acid" or the "electrolyte"

  • Battery Charging - Industrial Lead-Acid Safety Hazards
    Sulfuric acid is the acid used in lead-acid batteries (electrolyte) and it is corrosive Note: workers should never pour sulfuric acid into flooded lead acid batteries (included in new watering a battery section) If a worker comes in contact with sulfuric acid when watering a battery or when handling a leaky battery, it can burn and destroy
  • Forklift Trucks - Batteries - Canadian Centre for Occupational Health . . .
    like sulfuric acid or salts that can conduct electricity when dissolved in water Lead-acid batteries can produce explosive mixtures of hydrogen and oxygen gases when they are being charged Note that in some cases, hydrogen gas has been found to interfere with
  • CCOHS: Sulfur Dioxide
    The resulting sulfuric acid solutions are very corrosive and very toxic Dike and recover contaminated water for appropriate disposal Other Information: Contact supplier, local fire and emergency services for help
