Health Hazard Information
  • Skin Absorption/Skin Contact
  • Eye Contact
  • Inhalation
  • Unlikely as lighter than air and non toxicNormally non-toxic and non-irritating but high pressure injection of gas may damage the skin tissue.
  • Normally non-toxic & non-irritating but as pressurized gas may cause physical damage to unprotected eyes.
  • At high concentrations in enclosed areas it may displace sufficient oxygen to cause headache and loss of consciousness. CO2 has health affects when present in concentrations greater than 0.5%
Section VII: Preventive Measures
  • Personnel
  • Protective Equipments
  • Leak and Spill Procedures
  • Waste Disposal
  • Avoid direct contact
  • Normally non-toxic & non-irritating but as pressurized gas may cause physical damage to unprotected eyes.
  • Provide self contained breathing apparatus for higher concentrations, provide over clothing, hand gloves, safety goggles & shoes.
  • if you are indoor and smell gas:
    • Close all the valve and allow proper ventilation
    • Evacuate the persons from the premises.
    • Do not ON electrical/electronic switches and do not use any electrical appliance.
    • Do not light any match stick and lighter.
    • Close all the valve and allow proper ventilation
    If you are outdoor
    • Do not start / allow any gasoline engine like bike, car and gen-sets.
    • Do not allow to smoke near the area.
    • In both the cases (indoor & outdoor) please contact HCGDL emergency numbers
  • Allow the gas to burn under control
Section VIII: First Aid Measures
  • First Aid Measures
    • If inhaled, remove the person to fresh air and offer artificial respiration if required get medical help.
    • In case of skin contact, wash the skin with plenty of water.
    • Wash the eye with cold water in case of eye contact. If affected due to high pressure cover the both eyes with loose sterile dressing and immediately provide medical treatment.
