Eye Contact: Rinse cautiously with water for 15 minutes while holding eyelids open. Do not rub eyes. Contact a healthcare provider.
Ingestion: Rinse mouth thoroughly. Never give anything by mouth to an unconscious person. Seek emergency medical help immediately. Do not induce vomiting.
Notes for Physicians: Monitor for delayed symptoms; treat symptomatically; consider administration of antidotes for cyanide toxicity such as hydroxocobalamin.
Self-Protection: Use suitable PPE to avoid exposure during rescue.
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam
Unsuitable Media: Water jets may spread fire
Specific Hazards: Generates toxic and irritating gases such as hydrogen cyanide and nitrogen oxides under fire conditions
Protective Equipment: Full protective gear including self-contained breathing apparatus (SCBA)
Advice for Firefighters: Approach from upwind; prevent runoff from entering water supplies; cool containers with water spray
Decomposition Products: Hydrogen cyanide, carbon monoxide, nitrogen oxides
Personal Precautions: Evacuate area, ventilate space. Wear full protective clothing with NIOSH-approved respirator.
Environmental Precautions: Prevent from entering drains, surface water, and soil.
Clean-up Methods: Absorb spills with inert material such as sand or vermiculite. Place waste in sealed chemical waste containers for disposal. Decontaminate surfaces with dilute bleach solution.
Notification Procedures: Report large releases to local regulatory authorities.
Secondary Hazards: Vapors may be flammable; keep away from ignition sources.
Handling: Work in a well-ventilated area or fume hood. Use chemical-resistant gloves and protective goggles. Prevent skin and eye contact. Avoid breathing dust or vapor. Do not eat, drink, or smoke in work area.
Storage: Store in tightly closed containers in a cool, dry, well-ventilated facility away from direct sunlight and incompatible substances such as oxidizers, acids, and bases.
Storage Temperature: Recommended between 2°C and 8°C to maintain stability.
Incompatibilities: Strong oxidizing agents, strong acids or bases
Special Requirements: Secure storage location with restricted access. Label containers clearly.
Exposure Limits: No established OSHA/NIOSH legal limits, but practice stringent industrial hygiene controls for toxic nitriles
Engineering Controls: Use local exhaust ventilation, process enclosures, or other engineering controls to keep airborne concentrations below recommended limits
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile, neoprene), chemical splash goggles, lab coats or coveralls. Use full-face respirator with appropriate cartridges if significant dust or vapor is present.
Hygiene Measures: Wash hands and face before eating, drinking, or smoking. Remove contaminated clothing and launder before reuse.
Monitoring Methods: Use gas detection instruments in high-risk areas.

Conditions to Avoid: High temperature, open flames, sources of ignition, direct sunlight, incompatible materials
Incompatible Materials: Acids, alkalis, oxidizing agents
Hazardous Decomposition Products: Hydrogen cyanide, carbon oxides, nitrogen oxides
Routes of Exposure: Inhalation, dermal, oral
Acute Toxicity: Estimated oral LD50 (rat): 80 mg/kg (toxic if swallowed). Inhalation LC50 (rat): data limited but potentially low with rapid onset of central nervous system effects.

Serious Eye Damage/Irritation: Causes moderate irritation, redness, tearing
Respiratory Sensitization: Not classified; toxic effects predominate
Skin Sensitization: Not classified; irritation noted
