CO2 Safety

First Aid

For inhalation: Remove to fresh air.

Perform CPR and administer supplemental oxygen to someone who is not breathing. Obtain medical attention.

Several pamphlets for individuals wanting more information on handling carbon dioxide are available from the Compressed Gas Association, Inc (CGA), 1235 Jefferson Davis Highway, Arlington, VA 22202, phone (703) 979-0900. More information is also available from OSHA (Occupational Health and Safety Administration) at www.osha.gov.

Our atmosphere contains .03% carbon dioxide. It is a colorless gas with a slightly pungent odor that is only noticeable in high concentrations. In high concentrations CO2 displaces oxygen and is an asphyxiant. CO2 is denser than air, and can collect in open pits and other areas below grade – especially with inadequate ventilation.

Depending on the strength of the concentration and length of exposure, lower concentrations may cause symptoms such as headache, sweating, rapid breathing, increased heart rate, dizziness, mental depression, visual disturbances, or shaking.

• Know the hazards.
• Inspect and maintain all piping, tubing, hoses and fittings at regular intervals and maintain the system in accordance with manufacturer’s instructions.
• Make sure there is adequate ventilation. Open to the air is not enough. CO2 can pool in stairwells and other semi-enclosed areas below grade.
• Develop and implement procedures to monitor the atmosphere for CO2, and provide local ventilation where levels may exceed the permissible exposure limit.
• Place appropriate warning signs outside areas where high concentrations of the gas can accumulate.

CO2 atmospheric safety analyzers and alarms are available.
