There are many types of vasculitis. Each type involves inflamed blood vessels. However, most types differ in whom they affect and the organs that are involved. The types of vasculitis often are grouped based on the size of the blood vessels they affect.
Chlorine is supplied as a gas, liquid and a solid. The gas is 100 percent elemental chlorine (Cl2), and is supplied in 150 lb. cylinders (10 inches in diameter and about 55 inches high) and in 2,000 lb. (ton) containers (30 inches in diameter and 82 inches high).
At room temperature and pressure, carbon dioxide, or CO2, is a common gas, about 0.05 percent of the air at sea level by weight. It is also a product of combustion and the respiration of all animals. When chilled below minus 109 degrees Fahrenheit, it becomes a solid, called dry ice. Dry ice was first discovered and observed by French chemist Charles Thilorier in 1834. In 1925, the solid form of CO2 was trademarked by the DryIce Corporation of America as âDry iceâ. In the commercial production of dry ice, liquid carbon dioxide is chilled below minus 109 degrees Fahrenheit and compressed.
