• Flash point: This is the lowest temperature at which a liquid gives off enough vapor to form a mixture with air that can be ignited by a spark. Liquids with Flash points below I OOoF are considered Flammable, and liquids with Flash points between 100 and 200oF are considered to be combustible. Flammable and combustible liquids require special handling and storage precautions. • Extinguishing media: This section should specify what kind of fire extinguisher to use. There are four classifications of fires: Class A for paper and wood, Class B for more Flammable materials such as liquids or greases, Class C for electrical fires, and Class D for fires involving metals or metal alloys. • Special firefighting procedures and unusual fire and explosion hazards: For example, some chemicals (Such as corrosives) must not be extinguished with water in case of fire. Section V - Reactivity Data When stored improperly, some chemicals can react with other chemicals and release dangerous materials. This describes the reaction of chemicals when they are mixed together with other chemicals, or when stored or handled improperly. Section VI - Health Hazard Data This section describes the health effects of the product, including signs and symptoms of exposure and medical conditions made worse by exposure. Acute (short-term) and chronic (long-term) effects of exposure must always be included. MSDSs often leave out chronic health information, such as whether a chemical causes cancer or birth defects. Routes of entry (inhalation, skin contact, swallowing) and emergency and first aid procedures must also be Included. Unfortunately, a lot ofMSDSr in circulation do not contain complete and accurate health hazard information. This section must also contain information on target organs (liver, kidneys or central nervous system), signs or symptoms of exposure, medical conditions generally aggravated by exposure, and emergency First Aid procedures. Section VII - Precautions for Safe Handling and Use (Spill or Leak Procedures) This section contains information on proper equipment to use and what precautions to follow if a spill or leak occurs. It should also describe safe waste disposal methods and precautions to be taken in handling and storing. Section VIII - Control Measures The MSDS must list control measures that can reduce or eliminate the hazard, including ventilation and other engineering controls, safe work practices, and persal protective equipment. k°�°'- p1 AUG 222017 ENVIRONMENTAL HEALTH DEPARTMENT
