Herbal teas and fruit teas should not be confused with true teas (black, green, white, yellow, oolong, etc., which are prepared from the cured leaves of the tea plant, Camellia sinensis), as well as from decaffeinated tea, in which the caffeine has been removed.
Physical Hazard. OSHA defines a physical hazard as a chemical for which there is scientifically valid evidence that it is a combustible liquid, a compressed gas, explosive, flammable, an organic peroxide, an oxidizer, pyrophoric, unstable (reactive), or water-reactive.hysical Hazard.

Volatile liquids and solids, or liquids and solids with a high vapor pressure or low boiling point, are soluble in gas. It becomes especially easy to dissolve liquids and solids such as these in a supercritical fluid because of the high density. As can be noted from the Mole Fraction Solubility. The Mole Fraction Solubility is simply the ratio of the sublimation (or vapor pressure) to the total gas pressure.
