Liquefied Petroleum Gas

Move to fresh air. Do not leave the victim unattended. Keep patient warm and at rest. If unconscious place in recovery position. Seek immediate medical attention. If breathing is difficult, give oxygen if possible, or assisted ventilation. In the event of cardiac arrest, (no pulse), apply cardiopulmonary resuscitation.

Symptoms: Inhalation of vapours to high concentrations may cause asphyxiation.

Do not remove clothing that adheres due to freezing. Flush affected area with plenty of water. Continue for at least 15 minutes. If there are signs of frostbite, (blanching or redness of skin or burning or tingling sensation), do not rub, massage or compress the affected area. Send the casualty immediately to hospital.

Symptoms: frostbite, (blanching or redness of skin or burning or tingling sensation)

Remove any contact lenses. Flush eyes with water thoroughly and continuously for at least 15 minutes. Keep eye wide open while rinsing. If there are signs of frostbite, pain, swelling, lachrymation or photophobia persists, the casualty should be seen in a specialist health care facility.

Symptoms: frostbite, pain, swelling, lachrymation or photophobia

Large fire: Use water spray, water fog, water steam or foam. Small fire: Dry powder or carbon dioxide (CO₂) extinguisher, dry sand or fire fighting foam.

DO NOT use water jet. Simultaneous use of foam and water on the same surface is to be avoided as water destroys the foam.

LPG in gaseous phase is heavier than air, therefore explosive gas and air mixtures can accumulate in low non-ventilated areas. Vapours may travel long distances to ignition sources and flash back. Considerable amounts of toxic gas (CO, CO₂) may be emitted in case of fire. Containment vessels may explode under fire conditions.

Where possible stop the flow of gas, and if safe to do so. If the flow cannot be stopped allow the fire to burn out, whilst cooling containers, equipment and surroundings with a water spray.

Stop leak if safe to do so. Avoid direct contact with released material and breathing vapours. Stay upwind. Keep non-involved personnel away from the area of spillage. Alert emergency personnel. Enter area only if strictly necessary. A combustible gas detector can be used to check for flammable gas or vapours. Eliminate all ignition sources if safe to do so. Inform the downwind area in case of release of considerable amounts.

In case of release of considerable amounts of LPG, extensive amounts of explosive vapours heavier than air are formed which may travel long distances to the sources of ignition, therefore immediately inform the downwind area.

Prevent further leakage or spillage if safe to do so. Prevent spillage from entering drains or any place where accumulation may occur. Ensure adequate ventilation, especially in confined areas.

allow to evaporate

Ensure safe systems of work or equivalent arrangements are in place to manage risks. Smoking, eating and drinking should be prohibited. To avoid frostbite do not touch cold fittings, equipment, cylinders and tanks with liquefied gas barehanded.

Store in specifically designated storage facilities located in a safe distance from potential sources of ignition. Containers and tanks should be marked and warning boards should be placed as reference to safe equipment operation and product storage. For maintenance work or conservation, emptied tanks should be purged, and blanketed with inert gas (i.e. nitrogen).

Smoking, eating and drinking should be prohibited.

Ensure that all relevant regulations regarding explosive atmospheres, and handling and storage facilities of flammable products, are followed.

When performing various technical and production operations with LPG, vapours may be evolved into the atmosphere, and their concentration in workplace air should be controlled to the established acceptable level.

Wear petroleum product resistant gloves (e.g. acc. to EN 420, EN 388, EN 374-2, EN 374-3).

Wear safety goggles if eye contact may occur (e.g. acc. to EN 166).

When toxic gas is evolved during the work and employees are exposed to them, proper respiratory protection equipment, such as self-contained gas masks and self-contained breathing apparatus should be used. Respiratory protection equipment should be selected and used in accordance with the manufacturer's instructions and requirements established by law. NOTE. Filtering masks are hardly effective for protection against C₂, C₃ and C₄ hydrocarbons.

Wear protective clothing (e.g. acc. to EN 465) and other protection equipment. Protective clothes and equipment should be regularly inspected and maintained.

To ensure the compliance of ventilation and process equipment with requirements of environmental legal acts, emissions of such equipment are subject to check ups.

Stable at ambient temperature

No hazardous reaction when handled and stored according to provisions.

hazardous polymerization reactions will not occur

High ambient temperature. Avoid static electrical discharges and other ignition sources.

Avoid contact with strong oxidizing agents.

Partial decomposition (incomplete combustion) will evolve smoke, carbon dioxide, and highly harmful carbon monoxide. Concentration of toxic gas in a confined space or premises may reach a hazardous limit.
