Carbon Dioxide Safety Precautions
Carbon dioxide is a colorless, cryogenic liquid. At low concentrations, is odorless. At higher
concentrations carbon dioxide will have a sharp, acidic odor. At concentrations between 2 and
10%, Carbon dioxide can cause nausea, dizziness, headache, mental confusion, increased
blood pressure, and increased respiratory rate. If the gas concentration reaches 10% or more,
suffocation and death can occur within minutes. Contact with the cold gas can cause freezing
of exposed tissue. Moisture in the air could lead to the formation of carbonic acid that can be
irritating to the eyes. All forms of carbon dioxide are noncombustible. Carbon dioxide is
heavier than air and should not be allowed to accumulate in low lying areas.
WARNING Before using carbon dioxide, read the indications of hazard and the
instructions reported in the Safety sheet supplied by the manufacturer with reference to
the CAS number (Chemical Abstract Service) 124-38-9.
Use personal protection:
• Protective gloves : Loose fitting thermal insulated or leather gloves.
• Eye protection : Full face shield and safety glasses are recommended.
• Other protective equipment : Safety shoes when handling containers. Long sleeved
shirts and trousers without cuffs. Work clothing that sufficiently prevents skin contact
should be worn.
