Chemical name: β,β'-Oxydipropionitrile
CAS Number: 110-61-2
Concentration: 98–100%
Impurities/stabilizing additives: Trace solvents, water under 2%, stabilized with antioxidants as required
Inhalation: Move victim to fresh air. Keep airway clear. If breathing has stopped, start artificial respiration and call for emergency medical assistance right away. Provide oxygen if available and qualified.
Skin contact: Remove contaminated clothing. Wash skin thoroughly with soap and water for at least 15 minutes. Seek medical attention if irritation persists.
Eye contact: Rinse eyes carefully and thoroughly with water for 15 minutes, lifting upper and lower eyelids. Remove contact lenses if present and easy to do, then continue rinsing.
Ingestion: Rinse mouth with water. Never give anything by mouth if unconscious. Do not induce vomiting. Seek immediate medical attention.
Most important symptoms/effects: Drowsiness, headache, unconsciousness, labored breathing, skin irritation, eye redness; delayed neurological symptoms may occur.
Suitable extinguishing media: Dry chemical, carbon dioxide, alcohol-resistant foam. Use water spray to cool exposed containers but avoid full water jet.
Specific hazards: Produces toxic fumes of hydrogen cyanide, nitrogen oxides, and carbon monoxide during combustion. This material is combustible and may emit hazardous vapors if exposed to high heat.
Protective equipment for firefighters: Self-contained breathing apparatus (SCBA) and full protective gear. Approach fire from upwind position. Contain run-off to prevent environmental contamination.
Special firefighting procedures: Evacuate area and fight fire from a safe distance. Avoid inhalation of hazardous combustion products.
Personal precautions: Evacuate unnecessary personnel. Ventilate area. Use personal protective gear, including respiratory protection.
Environmental precautions: Prevent entry into water sources, sewers, basements, or confined areas. Notify environmental authorities if major spill occurs.
Cleanup methods: Absorb with inert material such as sand or vermiculite. Shovel into labeled containers for disposal. Wash affected areas with water and detergent.
Handling of residues: Treat collected material as toxic waste. Dispose of in accordance with local, regional, and national regulations.
Handling: Avoid inhalation, ingestion, and skin or eye contact. Use only in well-ventilated areas or under chemical fume hood. Prevent formation of dust or spray. Keep away from heat, sparks, and open flames. Use sparking tools and explosion-proof equipment.
Storage: Store in a tightly closed container in a cool, dry, well-ventilated place away from direct sunlight and incompatible chemicals such as oxidizers, strong acids, and bases. Ensure containers stay upright and labeled. Avoid storing near food or drink.
Occupational exposure limits: Consult local regulations—there may be no established OSHA/ACGIH exposure limits. Take a cautious approach, considering its acute toxicity.
Engineering controls: Use local exhaust ventilation or chemical fume hoods. Ensure eyewash stations and emergency showers are accessible.
Personal protective equipment: Respiratory protection (appropriate certified respirator in case of inadequate ventilation), chemical-resistant gloves (nitrile or neoprene), goggles or face shield, impervious clothing and footwear.
Hygiene measures: Wash hands thoroughly after handling, remove soiled clothing and wash before reuse, do not eat, smoke, or drink where chemicals are handled.

Hazardous decomposition products: Hydrogen cyanide, carbon monoxide, nitrogen oxides.
Likely routes of exposure: Inhalation, skin absorption, ingestion, eye contact.
Acute toxicity: Oral LD50 (rat): 80–250 mg/kg. Toxic if absorbed through skin or inhaled.
Delayed effects: Symptoms of nervous system depression, tremors, convulsions, delayed neurological effects may occur after exposure.
Skin corrosion/irritation: Causes skin irritation; may be absorbed through skin with systemic toxicity.
Serious eye damage/irritation: Irritating to eyes, may cause burns.
Carcinogenicity: No indication from existing studies, but chronic effects are not well-researched.
Reproductive/Developmental effects: No significant data; caution advised.
Target organ effects: Central nervous system, respiratory system, liver.
Ecotoxicity: Harmful to aquatic organisms. Can cause long-term adverse effects in the aquatic environment.
Persistence and degradability: Moderately persistent in water and soil. Slowly biodegradable by microorganisms under some conditions.
Bioaccumulative potential: Low, based on octanol-water partition and persistence.
Mobility in soil: May migrate into groundwater if released to environment due to slight water solubility.
Other adverse effects: Air dispersal may occur from volatilization. Environmental release must be minimized.
Waste treatment methods: Collect and dispose in accordance with local, state, and federal regulations. Large quantities require professional chemical waste disposal.
Disposal of containers: Triple rinse empty containers prior to disposal or recycling, puncture and render unusable. Dispose of residues as hazardous waste.
Environmental caution: Do not allow material or wash water to enter drains, sewers, or water courses.
