Document Summary
Essentials of environmental, occupational, and radiological health sciences (hsci 202) Exposure scenarios: time of exposure at job and home are high, routes of exposure in workplace. Ingestion, inhalation (most common), skin contact, and skin absorption. Women that are pregnant are a large concern in the workplace: chemicals exposed: Mixed substance: prevent exposure wearing body suits, goggles, gloves, etc, sources: Solvents: material used to dissolve another material, inorganic solvents: Health effect vasodilators, local irritants, some neurotoxicity, cancer. Alcohols, ketones, esters, ethers, glycols, aldehydes, phenols: physical/chemical properties of solvents. Boiling point temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor. Flash point the lowest temperature at which enough vapor is given off to propagate a flame with an ignition source. Fire point temperature at which there is enough vapor to support continuous combustion. Auto ignition temperature at which combustion will automatically occur.
