Control Number: <br />509.02.01.003 <br />Version: <br />2.0 <br />Title: <br />Hazardous and Flammable Materials <br />Handling and Control Procedures <br />Page Number: <br />5 of 12 <br /> <br /> <br />Liquid Petroleum Gas (LPG) <br />A product of petroleum gases, principally propane and butane , which must be stored <br />under pressure to keep it in a liquid state. The flashpoint of LPG is -160°F and the <br />flashpoint for butane is -76°F. <br />LPG is extremely flammable and cylinders must be handled with care. Propane is <br />heavier than air and leaked vapors may accumulate in low areas such as drains. LPG <br />and natural gas are scented with a pungent odor. If an odor is detected, do not allow any <br />open flame or other source of ignition such as switching on a light. Vacate the area <br />immediately and call for professional assistance. <br />LPG is extremely cold and will cause frost bite if exposed to the skin. Wear protective <br />clothing when connecting or disconnecting cylinders. <br />Compressed Gas <br />Compressed gas includes oxygen, chlorine , argon, and acetylene . <br />Chlorine Gas <br />Chlorine is irritating and corrosive to all living flesh. Chlorine liquid is amber colored; gas <br />is greenish-yellow with a sharp, suffocating odor. Individuals working on a chlorine <br />system under normal conditions must wear the following p rotective equipment: <br /> Gloves that are polyvinyl chloride (PVC), Teflon®, or Kel-F®; <br /> Safety goggles or glasses ; and <br /> An approved respirator with a canister approved for chlorine. <br />A respirator is only good for about 10 minutes in atmospheres having one (1) to two (2) <br />% chorine. A respirator will provide protection under normal conditions if a small amount <br />of chlorine is released when making or breaking connection in a line. A shower, eyewash <br />station, and self-contained breathing apparatus or positive pressure airline and mask <br />must be available for use in an emergency. Staff and inmates who work with or could be <br />exposed to chlorine gas must be familiar with the MSDS. <br />3. Materials Classification <br />Flammable Class I Liquids <br />Class IA – liquids with flashpoints below 73ºF and a boiling point below 100ºF. <br />Class IB – liquids with flashpoints below 73ºF and a boiling point at or above 100ºF. <br />Class IC – liquids with flashpoints at or above 73ºF and below 100ºF. <br />Examples of Class I flammable liquids include the following: <br />Acetone Gasoline Methyl ethyl ether <br />Benzene Hexane Naphtha Y,M, & P <br />Contact cement (flammable) Lacquer thinner Petroleum ether <br />Denatured alcohol Lacquer Toludi (toluene) <br />Ethyl alcohol Methyl ethyl ketone Xylene (xylol)
