Signs and Symptoms of Acute Ethylene Oxide Exposure: Signs and symptoms of acute exposure to ethylene oxide may be severe, and include dyspnea (shortness of breath), cough, pulmonary edema, pneumonia, and respiratory failure. Warning: Ethylene oxide is corrosive to moist tissues. Normalized Breakthrough Times (in Minutes) Chemical Information of DuPont or others covering any material or its use.

Provide: QUICK DRENCH (LIQUID) - Facilities for quickly drenching the body should be provided (when this chemical is in liquid form) within the immediate work area for emergency use where there is a possibility of exposure. Remove: WHEN WET (FLAMMABLE) - Work clothing that becomes wet should be immediately removed due to its flammability hazard (i.e., for liquids with a flash point <100☏).Ĭhange: No recommendation is made specifying the need for the worker to change clothing after the workshift. Wash skin: WHEN CONTAMINATED (LIQUID) - If this chemical is in liquid form, the worker should immediately wash the skin when it becomes contaminated. Skin: PREVENT SKIN CONTACT (LIQUID) - If this chemical is in liquid form, wear appropriate personal protective clothing to prevent skin contact.Įyes: PREVENT EYE CONTACT (LIQUID) - If this chemical is in liquid form, wear appropriate eye protection to prevent eye contact. Ethylene oxide and SO2 can react violently in pyridine solution with pressurization if ethylene oxide is in excess (Nolan, 1983, Case History 51).Įxcerpt from NIOSH Pocket Guide for Ethylene oxide : Violent reaction with m-nitroaniline, magnesium perchlorate, mercaptans, thiols, triethylamine. Violent polymerization occurs on contact with strong bases (alkali hydroxides, ammonia) or acids, amines, metallic potassium, oxides (aluminum oxide, iron oxide, rust), covalent halides (aluminum chloride, ferric chloride, tin(IV) chloride). Metal fittings containing magnesium, copper or silver should be avoided, since traces of acetylene in ethylene oxide may produce metal acetylides capable of detonating the vapor. Ethylene oxide vapor may be initiated into explosive decomposition in absence of air. Rapid compression of the vapor with air causes explosion. The autoignition temperature may be as low as 140☌ in presence of rust. Highly flammable, severe explosion hazard when exposed to flame. Avoid acids covalent halides such as chlorides of aluminum, iron (III), tin (IV) basic materials like alkali hydrides, ammonia, amines, and potassium catalytically active solids such as aluminum or iron oxides or rust, chlorides of boron, aluminum, tin, and iron some carbonates and metals such as copper and copper alloys (EPA, 1998)Ĭolorless gas at room temperature (b.p. Avoid air, heat, acids and bases, metal or metal chloride catalysts. Avoid metal fittings containing copper, silver, mercury or magnesium ammonia, oxidizing agents acids, organic bases amines certain salts alcohols mercaptans, ferric chloride magnesium perchlorate m-nitroaniline trimethylamine, potassium, tin chlorides alkanethiols bromoethane aluminum chloride aluminum oxide iron chlorides and iron oxides. Liquid is not detonable but the vapor may be readily initiated into explosive decomposition. Vapor forms explosive mixtures with air over a wide range. Vapor is heavier than air and may travel considerable distance to a source of ignition and flash back. Irritating vapors are generated when heated. Severe explosion hazard when exposed to heat or flame.
