Chemical Formula: C3H8 (Propane), C4H10 (Butane)
Recommended Use: Fuel for heating, cooking, vehicles, industrial processes
Supplier: Major energy companies and gas distributors
Emergency Contact: Local fire department or specialized hazmat teams
CAS Numbers: Propane: 74-98-6; Butane: 106-97-8; Isobutane: 75-28-5
UN Number: 1075
Proper Shipping Name: Liquefied Petroleum Gas
Classification: Extremely flammable gas, fire and explosion hazard
Hazard Symbols: Flame
Signal Word: Danger
Risk Phrases: Extremely flammable, may cause suffocation by reducing oxygen
Health Effects: Asphyxiation at high concentrations, possible dizziness, headache, or nausea
Physical Hazards: Gas under pressure, leak risk, rapid vapor expansion can cause frostbite
Environmental Risks: Rapid vaporization may cause dense ground-level clouds
Main Ingredients: Propane 60-100%, Butane 0-40%
Other Components: Small amounts of propylene, isobutane, and odorant (ethyl mercaptan)
Purity: Typically above 95% hydrocarbon content
Impurities: Trace sulfur compounds, moisture, olefins
Physical State: Colorless gas, liquefied under pressure
Inhalation: Remove victim to fresh air, call emergency services if symptoms persist, give oxygen if breathing trouble starts
Skin Contact: For frostbite by direct contact, warm area gently with water, never use hot water or rub skin, seek medical help immediately
Eye Contact: Flush with water at room temperature, hold eyelids apart, get medical advice if irritation remains
Ingestion: Not expected route, treat as inhalation
Advice to Doctor: Treat symptomatically, monitor for oxygen deprivation
Suitable Extinguishing Media: Dry chemical powder, CO₂, water spray (to cool containers, not for ignition directly)
Specific Hazards: Leakage can form explosive air-vapor mixtures, containers may rupture under fire conditions
Protective Equipment: Full protective suit, self-contained breathing apparatus
Special Procedures: Isolate area, remove sources of ignition, cool tanks with water spray
Combustion Products: Carbon monoxide, carbon dioxide, possible unburned hydrocarbons
Personal Precautions: Evacuate area, ventilate, eliminate ignition sources, use non-sparking tools
Protective Equipment: Anti-static clothing, gloves, eye/face protection, positive-pressure respirators
Environmental Precautions: Prevent from entering drains, sewers, basements
Spill Response: Shut off leak source if safe, allow gas to dissipate outdoors, notify emergency responders
Clean-up: Absorbent material not suitable, control vapor cloud by water spray if needed
Handling: Avoid inhalation and skin contact, use in well-ventilated places, ground all equipment, follow fire safety practices
Storage: Store in cool, dry, well-ventilated location, upright cylinders, away from heat or flame sources, secure containers
Safe Practices: No smoking or open flames, check for leaks using soapy water, label storage tanks clearly
Incompatible Materials: Strong oxidizers, chlorine, fluorine, strong acids
Occupational Exposure Limits: Propane TWA 1000 ppm (ACGIH), Butane TWA 800 ppm (ACGIH)
Engineering Controls: Explosion-proof ventilation, regular leak checks, gas detectors
Personal Protective Equipment: Flame-resistant gloves and clothing, goggles, face shield, approved respiratory protection for confined spaces
Hygiene Measures: Wash thoroughly after handling, avoid contaminated clothing
Special Precautions: Static discharge prevention by bonding/grounding
Appearance: Colorless gas, faint hydrocarbon odor, odorized for detection
Odor Threshold: Ethyl mercaptan at 1-2 ppm
Melting Point: Propane: -188 °C; Butane: -138 °C
Boiling Point: Propane: -42 °C; Butane: -0.5 °C
Vapor Pressure: 800-1200 kPa @ 20°C
Solubility in Water: Slight
Density (vapor): Heavier than air (1.5-2.1 x air)
Flammability Limits: Propane 2.1-9.5%, Butane 1.8-8.4% (in air)
Autoignition Temperature: Propane: 450 °C; Butane: 405 °C
pH: Not available (gas)
Chemical Stability: Stable under normal use and storage conditions
Hazardous Reactions: Explosive mixtures with air, reacts with oxidizers
Conditions to Avoid: Heat, sparks, open flames, direct sunlight, temperature extremes
Incompatible Materials: Halogens, oxidizing agents, concentrated acids
Decomposition Products: Toxic gases (CO, CO₂) on combustion
Acute Effects: Central nervous system depression, dizziness, nausea, suffocation at high concentrations
Chronic Effects: Repeated exposure may sensitize skin, rare effects on lungs
Potential Routes: Inhalation most likely, skin contact less common
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, OSHA
Other Risks: Frostbite from rapid evaporation, cardiac sensitization at high concentrations
Ecotoxicity: LPG dissipates rapidly, low toxicity to aquatic or terrestrial life in gas phase
Mobility: High; vapor rises quickly and disperses outdoors, heavier than air so can collect in low areas
Persistence/Degradability: Not expected to bioaccumulate, degrades by atmospheric processes
Bioaccumulation Potential: None
Other Impacts: Release to confined spaces can displace oxygen, concern for confined animal or plant environments
Disposal Methods: Vent in well-ventilated location where ignition source is controlled, consult local disposal regulations
Container Handling: Return unused cylinders to supplier, puncture and destroy if permitted by law and after confirming empty
Special Warnings: Do not incinerate closed containers, avoid landfill or water release
Reuse: Only refillable cylinders with supplier’s approval
