The Material Safety Data Sheet must be in the English language. MSDS sheets are created for a variety of hazardous materials including compressed gases, flammable and combustible liquids, oxidizing materials, poisonous or infectious material, corrosive material, and dangerously reactive materials. MSDSs are prepared by the supplier or manufacturer of the material. A Material Safety Data Sheet (MSDS) is a document that contains information on the potential hazards and how to work safely with the chemical products, as well as safety precautions for storing, handling, and transporting chemicals and emergency procedures all related to the hazards of the material.įor proper identification of material hazards, a material safety data sheet ( MSDS) should be prepared and supplied with each chemical so that its safety precautions can be well understood. Determined and published by the American Conference of Government Industrial Hygienists (ACGIH).MSDS stands for Material Safety Data Sheet. Threshold Limit Value Similar to PEL above but are not legal standards for human exposure. Teratogen A substance that may cause physical defects in the developing embryo or fetus when a pregnant female is exposed to that substance. Sensitizer A substance which may cause no reaction in a person during initial exposures, but upon a later exposure will cause an allergic response to the substance. ![]() Limit: Exposure limit (8 hour), a 15 minutes short term exposure limit STEL, or ceiling © limit. PEL may be either time-weighted-average (TWA). Permissible Exposure A human exposure limit that is published and enforced by OSHA as a legal standard. Oxidizer A substance that readily gives up oxygen to stimulate combustion of an organic material. Mutagen Anything which can cause a mutation in genetic material of a living cell. Generally in units of mg of material per kg of subject body weight. Lethal Dose (LD50) The dose of a substance that will kill 50% of the test animals in a group over a specified period of time following exposure. Generally expressed in units of parts per million or mg of contaminant m3 of air. ![]() Lethal Concentration (LC50) The concentration of air contaminant that will kill 50% of the test animals in a group during a single exposure (inhalation exposure). Irritant A substance that produces irritating effect when it contacts skin, eyes, nose, or respiratory system. Incompatible The term applied to two substances to indicate that one material cannot be mixed with the other without the possibility of a dangerous such as fire, explosion or release of toxic vapors. Hepatotoxic, Nephrotoxic, Neurotoxic Substances which are toxic to the liver, kidneys and nervous system, respectively. Flash Point The lowest temperature at which a liquid gives off enough vapor to form an ignitable mixture and will burn when a source of ignition is present. Flammable Liquid A liquid having a flash point below 100 degrees more ignitable than combustible liquids. Corrosive A substance that causes visible destruction or permanent changes in human skin tissue at the site of contact, e.g. Combustible Liquid Liquids having a flash point at or above 100 degrees. Chronic Exposure A prolonged exposure occurring over days, weeks or years. Carcinogen A substance or physical agent that may cause cancer in humans or animals. Asphyxiant A chemical (gas or vapor) that can cause death or unconsciousness by suffocation. ![]() Acute Exposure An intense exposure over a relatively short period of time.
