VIII. PYROPHORIC SUBSTANCES Characteristics • Warning: Pyrophoric substances ignite spontaneously upon contact with air. • All are flammable • Notify EH&S of use of pyrophoric prior to purchase to ensure proper safety equipment is available. Storage Precautions Potential Hazards Immediate Action Personal Protection • Use only in gas cabinet. Obtain approval from Fire Marshall prior to use. • Flow Restricting Orifice must be used when using silane. • Store in cool, dry, well-ventilated location • Materials must be stored under a blanket of inert gas. Fire • Ignites spontaneously on contact with air • May react violently with water oxidizing agents, halogenated hydrocarbons and alcohols Explosion • May be explosive when mixed with oxidizing materials Health • Can cause severe burns • Inhalation of some alkyl metal fumes can cause metal fume fever NOTIFY EH&S OF ANY RELEASE: • Beyond immediate work area • Causing injury • For fire, use dry sand or vermiculite • For phosphorous use water • Refer to MSDS – response must be material specific • Isolate area, and deny entry • Avoid breathing fumes • Keep upwind • Keep unprotected personnel away • Wear appropriate personal protection First Aid • Move victim to fresh air • Remove and isolate contaminated clothing • Remove material from skin immediately • In case of contact, flush skin or eyes with water for at least 15 minutes Common Pyrophoric Substances: Boron Butyllithium Cadmium† Calcium† Chromium† Cobalt† Diborane Dichloroborane 2-Furaldehyde Iron† Lead† Manganese† Methyllithium Nickel† Phorphorous, Yellow‡ Titanium† Selectride Silane †Finely divided metals form a pyrophoric hazard. ‡Phosphorous, Yellow should be stored and cut under water. 48
IX. CRYOGENIC FLUIDS Characteristics • Extremely low temperature (< -100°F) • Very large range of expansion from liquid to gas phase Storage Precautions Potential Hazards • Store only in Dewar flasks • Store in well-ventilated location Fire • Many are flammable • Some may condense oxygen from the air Explosion • Container may rupture if exposed to fire or relief valve fails Detection of Release Immediate Action Personal Protection Health • Although many are non-toxic, vapors in confined spaces can cause dizziness or asphyxiation • Contact can cause severe frostbite, burns. Eyes vulnerable to exposure • Cold boil off-gases condenses creating fog. • Most cryogenic liquids are colorless, odorless, tasteless except LOX which is blue. NOTIFY EH&S OF ANY RELEASE: • Beyond immediate work area • Causing personal injury • Extinguish fire using a suitable agent • Cool affected container, so not use water on material itself • Stop leak if you can do so without risk • Keep unprotected personnel away • Wear appropriate cryogenic protective clothing, eye protection and face shield • Use only in well ventilated places. • Cryogenics displaces oxygen. First Aid • Move victim to fresh air • If not breathing give artificial respiration • For frostbite, thaw frosted parts with water • Keep victim quiet • Maintain normal body temperature Common Cryogenic Fluids: Oxygen (LOX) Nitrogen (LN 2 ) Argon Hydrogen Helium Neon Xenon Liquefied natural gas (LNG) Expansion Ratio * (gas: liquid): Cryogenic Expansion Cryogenic Expansion Ratio Ratio Liquid argon 840 to 1 Liquid natural gas 635 to 1 Liquid fluorine 980 to1 Liquid neon 1,445 to 1 49
