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.

More energy is needed to separate them than short chain molecules which have only weak forces of attraction for each other. QUES: Name some of the compounds in the table and state whether the compound will be a gas, liquid, or solid state at room temperature (20oC). Hint: If the boiling point is below 20oC, then the liquid has already boiled and is a gas. What is the the boiling point trend in terms of the molecular weights of the compounds? At room temperature, the lighter alkanes are gases; the midweight alkanes are liquids; and the heavier alkanes are solids, or tars.
