Swallowed: Due to high volatility of product, this is not likely to occur.
Eyes: Do not delay – flood eyes gently with clean tepid water (not hot) for at least 15 minutes, or flush eyes for as long as possible with sterile saline solution. Seek medical attention.
Skin: Immediately bathe the area with large quantities of water (preferably tepid) for at least 15 minutes. If possible, remove any clothing splashed with liquid LPG that is not sticking to the skin. Place the injured person in a warm area and gradually rewarm the affected areas to normal body temperature. Do not apply any form of direct heat. Keep the person warm and comfortable. Loosen restrictive clothing. Gently cover the affected area with glad wrap or a wet, (not fibrous) material, ensuring that circulation is not restricted. Do not give anything to eat or drink. Never leave the injured person unattended. Keep contaminated clothing away from ignition sources as some gas may be given off during thawing. Seek medical attention.
Inhaled: Remove victim to fresh air. If breathing has stopped, or irregular, apply artificial respiration. Seek medical attention.
Advice to doctor: Treat symptomatically.
Fire/Explosion hazard: Evacuate area if required and remove ignition sources. Cut off gas supply if safe to do so – do not endanger life. Do not extinguish an LPG fire – allow gas to burn out. Drench and cool the LPG tank or cylinder with water spray from a safe distance. Wait for Emergency Services at a safe distance. Note: If ignition has occurred and water is not available or can’t be sprayed on the tank or cylinder safely, the metal may weaken from the heat and explode. The potential affected area should be evacuated immediately, and emergency services notified from a safe location. Note: If it is essential to extinguish the fire then use only dry chemical powder extinguishers.
Combustion products: Carbon dioxide, water vapour, traces of carbon monoxide and nitrogen oxides. Fumes, smoke, carbon monoxide and aldehydes can be formed during incomplete combustion. Note: Fire fighters may need self-contained breathing apparatus.
Advice to Firefighters: Temperatures in a fire may cause the tank or cylinder(s) pressure relief devices to open and release gas, or eventually rupture. Cool the tank or cylinder(s) exposed to fire by applying water spray from a protected location.
Personal precautions, protective equipment and emergency procedures: Evacuate area if required and remove ignition sources. Stop flow of gas/liquid if safe to do so – do not endanger life. Move people from potential affected area, keep up-wind. Notify emergency services. Stop flow of gas/liquid if safe to do so. Spray water mist to disperse the gas cloud but avoid spraying water directly on leaking container as this may increase leakage. Prevent spillage from spreading or entering underground drains by blocking with wetted cloths, sand or earth.
Safe handling: Use of safe work practices are recommended to avoid eye or skin contact. Do not drag, drop or roll cylinders. The uncontrolled release of a gas under pressure may cause physical harm.
Conditions for safe storage: Do not store near sources of ignition or incompatible materials. Cylinders should be stored upright, on a firm and stable surface. Cylinders should be stored in an accessible, well-ventilated area.
Additional details: Health and Safety at Work (Hazardous Substances) Regulations 2017, Hazardous Substances and New Organisms Act (HSNO) 1996, NZS 5433 Transport of Dangerous Goods on Land 2012, Relevant LPGA Codes of Practice, AS/NZS 1596 Storage and Handling of LP Gas 2014
Workplace exposure standard (WorkSafe January 2018):
Propane is a simple asphyxiant and displaces oxygen from air. It presents an explosion hazard.
Butane TWA 800 ppm, 1900 mg/m3
LPG 1,000 ppm, 1800 mg/m3
Ventilation: Use with adequate ventilation. Confined spaces and low-level areas should be well ventilated to prevent gas accumulating and displacing air. Flammable/explosive concentrations may accumulate in confined spaces and at low levels. Confined spaces should be tested for the presence of LPG prior to entry.
Personal protective equipment: The selection of PPE is dependant on a detailed risk assessment. The risk assessment should consider the work situation, the physical form of the product, the handling methods, and environmental factors.
Recommendations:
| Property | Details |
|---|---|
| Appearance | Colourless gas |
| Odour | Odorised (Ethyl Mercaptan) – rotten egg odour |
| Boiling point | –42°C (Propane), –0.5°C (Butane) |

Stability: Stable under normal conditions of use.
Conditions to avoid: Avoid heat, sparks, open flames, and other ignition sources.
Incompatible materials: Strong oxidising agents.
Hazardous decomposition products: Carbon dioxide, carbon monoxide.
Information on toxicological effects:
LPG has low toxicity under normal usage conditions. At high concentrations, it may act as an asphyxiant. Inhalation may cause dizziness and central nervous system depression. Direct contact with liquid LPG can cause severe cold burns or frostbite.
Ecotoxicity: LPG is not expected to have any significant environmental impact.
Persistence and degradability: LPG will rapidly evaporate and disperse in the atmosphere.
Disposal methods: Ensure cylinders are empty before disposal. Dispose of in accordance with local regulations.
