Synonym:2-Butoxytetrahydrofuran, all isomers Section 2 - COMPOSITION, INFORMATION ON INGREDIENTS
Risk Phrases: 36/37 Section 3 - HAZARDS IDENTIFICATION EMERGENCY OVERVIEW
Irritating to eyes and respiratory system. Potential Health Effects Eye: Causes eye irritation. Skin: May cause skin irritation. Ingestion: May cause gastrointestinal irritation with nausea, vomiting and diarrhea. The toxicological properties of this substance have not been fully investigated. Inhalation: Causes respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. Chronic: No information found. 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. Skin: Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Ingestion: Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or 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: Treat symptomatically and supportively. Section 5 - FIRE FIGHTING MEASURES General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Water may be ineffective. Material is lighter than water and a fire may be spread by the use of water. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. Containers may explode when heated. Extinguishing Media: Use extinguishing media most appropriate for the surrounding fire. 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. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, observing precautions in the Protective Equipment section. Remove all sources of ignition. Provide ventilation. Section 7 - HANDLING and STORAGE Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Keep away from heat and flame. Avoid breathing vapor or mist. Storage: Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Containers should be dated when opened and tested periodically for the presence of peroxides. Should crystals form in a peroxidizable liquid, peroxidation may have occurred and the product should be considered extremely dangerous. In this instance, the container should only be opened remotely by professionals. All peroxidizable substances should be stored away from heat and light and be protected from ignition sources. 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 ventilation to keep airborne concentrations low. Exposure Limits CAS# 1927-59-9: CAS# 62987-01-3: Personal Protective Equipment Eyes: Wear chemical splash goggles. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin. Respirators: A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant respirator use.

Substances with similar functional groups form explosive peroxides. Conditions to Avoid: Light, ignition sources, excess heat. Incompatibilities with Other Materials: Strong oxidizing agents. Hazardous Decomposition Products: Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide. Hazardous Polymerization: Has not been reported Section 11 - TOXICOLOGICAL INFORMATION RTECS#: CAS# 1927-59-9 unlisted. CAS# 62987-01-3 unlisted. LD50/LC50: Not available. Not available.
