Name: Allyl Chloroformate [Stabilized]
Chemical Formula: C4H5ClO2
Physical Appearance: Clear, colorless to yellowish liquid, sharp odor reminiscent of acid and ether combined
Common Uses: Synthesis of organic intermediates, laboratory reagent, contribution to pharmaceutical manufacturing
Hazard Classification: Highly flammable liquid, toxic on inhalation, skin contact, and ingestion, causes severe skin and eye burns, can damage respiratory systems
Label Elements: Flame, skull and crossbones, corrosive symbols
Primary Risks: Immediate burning sensation, coughing, tearing, dizziness, possible pulmonary edema
Additional Hazards: Reacts violently with water, alcohols, amines, strong bases
Chemical Name: Allyl Chloroformate
Concentration: Pure or stabilized with specific inhibitors to reduce hazardous reactions, percentage varies by supplier and stabilization method
Impurities: Trace levels of stabilizers and residual allies
Inhalation: Move to fresh air immediately. If breathing stops, provide artificial respiration and seek urgent medical attention
Skin Contact: Remove contaminated clothing, rinse skin with large amounts of water for at least 15 minutes. Chemical burns need prompt hospital treatment
Eye Contact: Rinse eyes gently but thoroughly with water for at least 15 minutes, keeping eyelids apart, seek immediate care
Ingestion: Do not induce vomiting, rinse mouth, seek emergency help without delay
Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, alcohol-resistant foam work best; water can cause dangerous reactions
Special Hazards: Forms toxic and corrosive gases on combustion, including phosgene, hydrogen chloride, carbon oxides
Protective Gear: Full-face self-contained breathing apparatus, chemical-proof suits preferred
Personal Precautions: Approach upwind. Keep unnecessary personnel away due to volatility and toxic fumes
Personal Protection: Wear full chemical splash suit, gloves, goggles, and use respiratory protection
Spill Cleanup: Ventilate area, use inert absorbents like sand or vermiculite, avoid letting spills contact water
Disposal: Use sealed, labeled chemical waste containers for all cleanup materials, handle as hazardous waste
Avoidance: Keep out of drains, surface waters, sewers to reduce environmental and explosion risk
Handling: Work in well-ventilated fume hoods, avoid inhaling vapors, prevent skin and eye contact, use spark-proof tools, limit quantities in use
Storage: Store in cool, dry, well-ventilated area, tightly closed, away from heat, sparks, and incompatible chemicals like amines and water
Segregation: Do not store with strong bases, alcohols, acids, or oxidizers
Engineering Controls: Use local exhaust ventilation, fume hoods, or glove boxes to reduce exposure
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene preferred), splash-proof goggles, flame-retardant lab coat
Respiratory Protection: Approved respirators for organic vapor exposure during high-risk operations or spill response
Hygiene Practices: Wash hands and face after handling, remove contaminated clothing promptly
Odor: Pungent, irritating
Boiling Point: 93°C-94°C
Melting Point: -80°C
Flash Point: 14°C (closed cup)
Vapor Pressure: Moderate, increases sharply with temperature
Solubility: Reacts with water
Density: Approximately 1.13 g/cm³ at 20°C
Stability: Stabilizers slow down hazardous decomposition, but instability increases with heat or exposure to moisture
Incompatible Materials: Strong bases, acids, water, alcohols, amines, oxidizers
Hazardous Decomposition: Hydrogen chloride, carbon monoxide, phosgene, other toxic gases
Polymerization: Can occur when stabilizer is absent or exhausted
Acute Effects: Severe burning and irritation of skin, eyes, mucous membranes, nausea, vomiting, lung irritation
Chronic Effects: Possible sensitization, long-term damage to respiratory tract, repeated skin contact amplifies sensitivity
Routes of Exposure: Absorbs through skin, inhalation of vapor, accidental ingestion
Carcinogenicity: Long-term effects under study, no confirmed cancer classification
Environmental Impact: Highly toxic to aquatic organisms, potential for long-term adverse effects in water streams
Persistence: Undergoes chemical breakdown, but byproducts such as hydrochloric acid and allyl derivatives remain hazards
Bioaccumulation: Low, but acute toxicity to life in water is significant
Waste Treatment: Incinerate in controlled facilities with suitable scrubbers for fumigants
Container Disposal: Triple rinse, vent used containers, puncture and dispose following hazardous waste regulations
Avoidance: Never pour down drains, avoid uncontrolled landfills
Shipping Category: Dangerous goods, flammable, toxic, corrosive
Packaging Requirements: Leak-proof, impact-resistant, segregation from incompatible substances
Handling: Mark clearly with hazard labels, provide emergency protocols for fire or leak response during transit
Incident Readiness: Drivers and handlers should have access to breathing protection and spill kits
Status: Regulated under hazardous substance laws due to flammability, acute toxicity, water reactivity
Labeling: Requires hazard pictograms, specific warnings, stringent storage signage
Workplace Controls: Agencies set occupational exposure limits and enforce training for handling and spill response
Community Right-to-Know: Facilities storing significant amounts must inform local emergency planning committees and follow public notification rules
