Beware that improperly installed or poorly maintained carbonated beverage systems can create hazardous concentrations of carbon dioxide (CO2) in enclosed areas, causing restaurant patrons and employees severe, sometimes fatal, harm.
CO2 in the gaseous state is colorless and odorless and not easily detectable. It can be deadly even when normal oxygen levels are present. Reaching hazardous levels of CO2 can occur quickly, without warning, and result in serious health issues or death. Because gaseous CO2 is 1.5 times heavier than air, leaking CO2 can accumulate at floor level in improperly ventilated or unventilated rooms and in low areas, such as basements. Even small slow leaks can cause hazardous concentrations of CO2.
Ventilation systems should exhaust from the lowest level and allow make-up air to enter at a higher point to maintain a safe environment. CO2 detectors with alarm systems should be installed in appropriate areas to detect hazardous concentrations levels. Butler Gas offers safe, effective systems for all gases, including CO2.
