Synonym:Borane-pyrrole; 1-Boryl-1H-pyrrol Section 2 - COMPOSITION, INFORMATION ON INGREDIENTS
Risk Phrases: 11 15 19 36/37 Section 3 - HAZARDS IDENTIFICATION EMERGENCY OVERVIEW
Highly flammable. Contact with water liberates extremely flammable gases. May form explosive peroxides. Irritating to eyes and respiratory system.Moisture sensitive. Potential Health Effects Eye: Contact with eyes may cause severe irritation, and possible eye burns. Vapors may cause eye irritation. Skin: May cause skin irritation. May be absorbed through the skin in harmful amounts. Prolonged and/or repeated contact may cause defatting of the skin and dermatitis. Ingestion: May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause headache. May cause unconsciousness. May be harmful if swallowed. May cause central nervous system depression. Inhalation: Inhalation of high concentrations may cause central nervous system effects characterized by nausea, headache, dizziness, unconsciousness and coma. Causes respiratory tract irritation. May cause narcotic effects in high concentration. Chronic: Prolonged or repeated eye contact may cause conjunctivitis. Prolonged or repeated skin contact may cause defatting and dermatitis. May cause liver and kidney damage. Section 4 - FIRST AID MEASURES Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Skin: Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists. Discard contaminated clothing in a manner which limits further exposure. Ingestion: If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid. Wash mouth out with water. Inhalation: Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. Notes to Physician: Section 5 - FIRE FIGHTING MEASURES General Information: Vapors can travel to a source of ignition and flash back. Wear appropriate protective clothing to prevent contact with skin and eyes. Wear a self-contained breathing apparatus (SCBA) to prevent contact with thermal decomposition products. Extremely flammable liquid and vapor. Forms peroxides of unknown stability. Extinguishing Media: Do NOT use water directly on fire. Use water spray to cool fire-exposed containers. Use foam, dry chemical, or carbon dioxide. Water may be ineffective. Section 6 - ACCIDENTAL RELEASE MEASURES General Information: Use proper personal protective equipment as indicated in Section 8. Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Remove all sources of ignition. Use a spark-proof tool. Section 7 - HANDLING and STORAGE Handling: Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Keep away from heat, sparks and flame. Avoid ingestion and inhalation. Use only in a chemical fume hood. Prevent build up of vapors to explosive concentration. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Storage: Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a cool place in the original container and protect from sunlight. Store in a tightly closed container. Refrigerator/flammables. Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION Engineering Controls: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits. Exposure Limits CAS# 45376-40-7: Personal Protective Equipment Eyes: Wear safety glasses and chemical goggles if splashing is possible. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin. Respirators: Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.

Conditions to Avoid: Prolonged exposure to air and sunlight may form unstable peroxides., incompatible materials, light, ignition sources, exposure to moist air or water. Incompatibilities with Other Materials: It is explosive with potassium hydroxide, sodium hydroxide, and sodium tetrahydroaluminate since caustic alkalies deplete the inhibitor. Reacts with potassium dioxide 2-aminophenol to form an explosive product. Reacts violently with metal halides. Forms explosive hydrogen gas with borane or lithium tetrahydroaluminate and reacts vigorously with bromine and calcium hydride+heat. Incompatible with sulfinyl chloride and oxidizing materials. Hazardous polymerization may occur in the presence of cationic initiators such as strong proton acids or selected Lewis acids. Hazardous Decomposition Products: Nitrogen oxides, carbon monoxide, carbon dioxide, oxides of boron, borane. Hazardous Polymerization: Has not been reported.
