Carbon dioxide gas is a natural byproduct of the respiration system. It has a wide variety of industrial and practical uses, and is often transported in pressurized containers. Carbon dioxide must be handled, transported and stored with great care.
Skin Exposure
Carbon dioxide is often super cooled to condense the gas for more efficient storage. Skin exposure to this gas can cause immediate frostbite. Safety gloves and clothing should be worn when working with carbon dioxide.
Breathing
Carbon dioxide occurs naturally in the atmosphere at a level of .035 percent. Exposure to levels above this can cause difficulty breathing, nausea, dizziness and eventual depression of the central nervous system. Levels should be tested to ensure safety.
Eye Exposure
Carbon dioxide gas that leaks into an eyeball can cause serious damage. Always wear protective goggles, but in case of exposure rinse eyeball for up to 15 minutes in warm water and consult an ophthalmologist immediately.
Asphyxiant
Carbon dioxide is an asphyxiating gas, meaning it pushes other less asphyxiating gasses like oxygen out of an area. Increased levels of carbon dioxide may not kill you directly, but can be dangerous because they are removing oxygen, essential for life.
Valve Safety
When handling carbon dioxide gas in a pressurized container, never lift it by the cap. Also, do not try to pry open the cap with any other tool than an adjustable strap wrench, as this may lead to tank penetration. Keep upright during use and keep free from flames.
