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.

Even amorphous materials have some shortrange order at the atomic length scale due to the nature of chemical bonding (see structure of liquids and glasses for more information on non-crystalline material structure).hether a material is liquid or solid depends primarily on the connectivity between its elementary building blocks so that solids are characterized by a high degree of connectivity whereas structural blocks in fluids have lower connectivity (see figure on amorphous material states).
