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).
Chemical reference number (CAS): 124-38-9. At room temperature, carbon dioxide (CO2) is a colorless, odorless, faintly acidic-tasting, non-flammable gas. CO2 is the fourth most abundant gas in the earth's atmosphere. Depending on the temperature and pressure, carbon dioxide can also exist as a liquid or a solid. In its solid form, carbon dioxide is called dry ice because it slowly changes from a cold solid directly into a gas.
