Pyrophoric materials handbook

PYROPHORIC METALS References in the text to these general classes or groups of materials is always in small capitals to differentiate them from references to specific chemicals, the names of which are given in normal roman typeface. Some individual materials of variable composition (substances) and materials Pyrophoric chemicals are chemicals that will ignite in air (below 130 °F) in the absence of added heat, shock., or friction. Common pyrophoric solids include Titanium Dichloride and Phosphorous. Sodium, Butyllithium, and Lithium Hydride are spontaneously flammable in moist air, as they react exothermically with water. II. Hazard Assessment Once a pyrophoric material begins burning, it can be very difficult to extinguish. Pyrophoric-specific spill adsorbents and fire extinguishing materials include dry sand, powdered soda ash (sodium carbonate), calcium oxide (lime), Celite® (diatomaceous earth), and clay based kitty litter. Propylene oxide may react vigorously with oxidizing materials, anhydrous metal chlorides, acids, bases, clay-based adsorbent materials, and peroxides. Propylene oxide mixed with ammonium hydroxide, chlorosulfonic acid, hydrochloric acid, hydrofluoric acid, nitric acid, oleum (fuming sulfuric acid), or sulfuric acid causes violent reactions. ̶ Pyrophoric Lab Chemicals (list of examples) ̶ Pyrophoric ̶ Liquid Safety Video • UCI . ̶ Procedures for Safe Use of Pyrophoric Reagents 05/10/99 • UCSD . ̶ Handling Pyrophoric and Other Highly Reactive Materials Videos: ̶ Part One: Getting Ready ̶ Part Two: Transferring Pyrophoric Liquids ̶ Part Three: Working with Reactive Metals According to Webster's dictionary, "pyrophoric material" means "any material igniting spontaneously or burning spontaneously in air when rubbed, scratched, or struck, e.g. finely divided metals". Iron sulfide is one such pyrophoric material that oxidizes exothermically when exposed to air. A pyrophoric substance (from Greek πυροφόρος, pyrophoros, "fire-bearing") ignites spontaneously in air at or below 55 °C (130 °F). Examples are iron sulfide and many reactive metals including uranium, when powdered or thinly sliced.Pyrophoric materials are often water-reactive as well and will ignite when they contact water or humid air. They can be handled safely in atmospheres of @article{osti_288679, title = {Definition of safe feedslate and operating windows in an olefins plant}, author = {Chan, P S and Sellinger, D}, abstractNote = {Safety related procedures and practices have evolved over the years with the OSHA 1910 regulations established as the most recent benchmark. Documentation of the safe upper limits for flow or composition is now required along with the Due to a planned power outage on Friday, 1/14, between 8am-1pm PST, some services may be impacted. A limited list of pyrophoric chemicals is provided in Appendix B. For a detailed list of pyrophoric and water-reactive chemicals (not all inclusive), refer to Bretherick's Handbook of Reactive Chemical Hazards Sixth Edition Volume 1. 5.0 CONTROLLING HAZARDS Handling of pyrophoric and water-reactive chemicals are typically high risk activities and A pyrophoric substance is a substance that ignites spontaneously: that is, its autoignition temperature is below room temperature. Examples are iron sulfide and many reactive metals including uranium, when powdered or sliced thinly. Pyrophoric materials are often water reactive as well and will ignite when they contact wate
