Carbon dioxide is widely used in breweries and in the manufacture of carbonated drinks which makes brewers and carbonated beverage workers particularly at risk of exposure.
Workers entering enclosed areas when cleaning out tanks and vats are susceptible to exposure to high levels of CO2
Low concentration of carbon dioxide are naturally present in the air and are not harmful to human health.
However, high concentrations displace oxygen in the air causing immediate breathing difficulties and rapid onset of exposure symptoms. In addition, carbon dioxide is both colourless and odourless making it difficult to detect
