Carbon Dioxide Threatens Health and Life
Wednesday, February 1st, 2012Compressed Gas Association Issues Safety Alert
Due to recent incidents caused by incorrectly installed or poorly maintained carbonated beverage systems, the Compressed Gas Association, Inc. has issued a safety alert. Faulty systems can cause carbon dioxide to leak and hazardous levels of the gas to build up in enclosed areas leading to illnesses or even deaths to restaurant customers and workers and to emergency responders. Carbon dioxide is used in numerous workplaces and has been recognized for many years as a workplace hazard.
The principle issue with carbon dioxide gas is that it can quickly accumulate without the knowledge of the individuals present in the area. It is colorless and doesn’t smell. Since carbon dioxide is heavier than air, it gathers at floor level in improperly ventilated areas, including basements, pits, tanks, and sumps and outside areas like trenches or depressions where it displaces oxygen.
Carbon dioxide is naturally present in the air at low levels and normally does not cause any harmful effects. At higher levels, however, the physical effects include feeling an inability to breathe, increased pulse, headache, sweating, disorientation. With exposure to very high concentrations and/or over longer periods of time, damage to the retina, difficulty breathing, impaired hearing, nausea and vomiting, convulsions, and loss of consciousness can result. Deaths due to asphyxiation have occurred.
According to the Compressed Gas Association, some sources of hazardous concentrations of carbon dioxide are:
“-Carbon dioxide storage containers that are not properly vented to a well-ventilated area outside of the building not just into walls or ceilings;
-Leaking fittings, connections, piping/tubing/hoses, or storage container plumbing;
-Leaking carbonators, syrup pumps, bag in box (BIB) racks (i.e., any equipment using carbon dioxide); and
-Leaking beer keg connections and equipment.”
To avoid harm from carbon dioxide, detectors with alarm systems should be installed in areas where equipment is used. All systems using carbon dioxide should be installed and maintained according to the manufacturer’s directions. Proper ventilation is essential. Employees and any others using the equipment should be trained on how to use the systems and on the dangers and characteristics of carbon dioxide.
