4/14/2015R-4, File: Hazcom-R4.ppt11 IMPORTANT TERMS ACUTE: Effects usually occur rapidly as a result of short-term exposures and are of short duration. CHRONIC: Effects generally occur as a result of long-term exposure and are of long duration. REMOTE: Effects occur in internal organs caused by absorbed chemicals. LOCAL: Effects where visible irritation occurs at the site of contact. P.E.L.: Permissible Exposure Limit
4/14/2015R-4, File: Hazcom-R4.ppt12 IMPORTANT TERMS CARCINOGEN: capable of causing cancer. MUTAGEN: Capable of causing change in human DNA. TERATOGEN: Causes defects in embryos. TOXIC: A relatively small amount of this chemical can cause illness or death.
4/14/2015R-4, File: Hazcom-R4.ppt13 IMPORTANT TERMS STABLE: Chemical remains unchanged under normal circumstances. REACTIVITY: A substance’s tendency to undergo chemical reaction either by itself or with other materials with the release of energy. INCOMPATIBLE: Direct contact between incompatible chemicals causes dangerous reactions. WATER REACTIVE: Reacts with water to release a gas that is flammable or unhealthy.
4/14/2015R-4, File: Hazcom-R4.ppt14 IMPORTANT TERMS FLASHPOINT: The temperature at which a liquid or solid gives off enough vapor in air to form a flammable mixture. The lower the flashpoint, the more flammable the material. COMBUSTIBLE: Capable of being ignited. – Liquid with flashpoint between 100 and 200 degrees F. FLAMMABLE: A liquid chemical having a flashpoint of under 100 degrees F.
4/14/2015R-4, File: Hazcom-R4.ppt15 IMPORTANT TERMS Boiling Point: The temperature at which a liquid changes its phase to a vapor or gas, where vapor pressure of the liquid equals atmospheric pressure. Significant property for evaluating the flammability of a liquid, as flash point and boiling point are directly related. A liquid with a low flash point will also have a low boiling point, which translates into a large amount of vapors being given off.
4/14/2015R-4, File: Hazcom-R4.ppt16 IMPORTANT TERMS Melting Point: Temperature at which a solid changes its phase to a liquid. This temperature is also the freezing point depending on the direction of the change. For mixtures, a melting point range may be given. This is a significant property in evaluating the hazards of a material, as well as the integrity of a container (e.g., frozen material may cause its container to fail).
4/14/2015R-4, File: Hazcom-R4.ppt17 IMPORTANT TERMS SOLUBILITY: Amount of a material that will dissolve in water at ambient temp. SPECIFIC GRAVITY: Weight of a liquid in relation to water (H 2 0=1). If it has a specific gravity greater than 1, it is heavier than water. If it is lower than 1 it floats to the top. VAPOR DENSITY: Weight of a gas compared to air. Air = 1. Any gas with a VD of less than 1 is lighter and rises. Any gas with a VD of greater than 1 is heavier and will pool in low lying areas.
4/14/2015R-4, File: Hazcom-R4.ppt18 IMPORTANT TERMS Volatility: The ease with which a liquid or solid can pass into the vapor state. The higher a material’s volatility, the greater its rate of evaporation. This is a significant property in that volatile materials will readily disperse and increase the hazard area.
4/14/2015R-4, File: Hazcom-R4.ppt19 Toxicology: The study of poisons
4/14/2015R-4, File: Hazcom-R4.ppt21 Concentration or Dose Usually, but not always, the speed and magnitude of the material’s action is in direct proportion to the dose. Remember - dose makes the poison! Rate of absorption is affected by the rate of exposure. Rate of detoxification is possible only if rate of absorption is less than the rate the body can destroy or neutralize, eliminate or excrete the toxin.
4/14/2015R-4, File: Hazcom-R4.ppt22 Remember The lower the reported concentration, the more toxic the material.

4/14/2015R-4, File: Hazcom-R4.ppt24 Chemical Routes of Entry to the Body IngestionIngestion-by mouth InjectionInjection-cuts, punctures, etc. Skin AbsorptionSkin Absorption- through the skin. InhalationInhalation - by breathing the fumes.
4/14/2015R-4, File: Hazcom-R4.ppt25 Hygiene Precautions Routes of entry are vulnerable to infectious diseases. Preventive measures include: –Proper use of PPE. –No eating, drinking or using tobacco products (especially spitting) in the workplace. –Washing hands often.
4/14/2015R-4, File: Hazcom-R4.ppt26 Alarming but True... Reports of take-home toxin poisoning have been reported in 28 countries and 36 of the States in the U.S. Some of the incidents resulted in life-threatening illnesses. OSHA continues to issue citations for Hazcom at nearly twice the rate of the second nearest violation.
4/14/2015R-4, File: Hazcom-R4.ppt27 Steps to Prevent “HOME” Poisoning Shower before leaving work. Isolate work clothes and wash them separately. Avoid taking tools, supplies, and small amounts of chemicals into the home.
4/14/2015R-4, File: Hazcom-R4.ppt28 Physical Hazards: What can get you if toxins don’t… –Fire –Explosion –Radiation –Corrosives –Compressed Fluids –Etc….
