The risks of CO2

There is no reason to put yourself at risk of dangerous levels of CO2! Even a small increase in CO2 concentration in the air is dangerous for humans. Normal outside air has an average CO2 concentration of only 0.04%. At a concentration of 1.5% CO2, people react with an increased heart rate; at 4% CO2 there is an immediate danger to life and health (IDLH).

As CO2 is used more and more in a wide range of applications, people are at risk of exposure to CO2 concentrations above the IDLH (Immediate Danger to Life and Health) value in their daily life, at work and during leisure time health) to inhale. For example fermentation gases in wineries and breweries or restaurants and pubs where carbonated soft drinks are served.

In order to avoid accidents, employers and employees must be aware of the risks of working with CO2 gas, be able to recognize early symptoms and be protected by a fixed or portable CO2 safety system.

Common symptoms of CO2 exposure include dizziness, headaches, poor sleep, fatigue, anxiety, eye changes, coronary artery disease, gastritis, kidney and liver damage, eye and skin burns, and dermatitis. These symptoms only occur when the NIOSH Standard Recommended Exposure Limit (REL) and/or the OSHA (Occupational Safety & Health Administration) Standard Permissible Exposure Limit (PEL) exceeds 5000 ppm.
