LPG Gas Safety Information

Used correctly, LPG is a safe product. However, being a combustible fuel, we must recognise the potential dangers it can present and minimise risk to our customers, employees and the wider public alike.

At Flogas, we view Safety as our top priority. We have a rigorous process of Safety Management across our organisation and at customer installations. This includes a programme of random site audits, staff training for all depot staff and tanker drivers, and monthly performance reviews by myself at Board level.

The core foundation behind the process is a genuine culture of safety across all staff who place safety at the heart of everything we do. We never take safety for granted, and encourage our customers to take a similar approach. We would therefore encourage any-one using LPG to read through this Safety and Technical section, and consider your approach to safety.

The menu tabs on the left of this page have been designed to give customers an easily accessible guide to LPG and how best to manage it, from dealers storing and transporting large quantities of LPG to domestic users with a bulk supply, or even just a cylinder for a Barbecue (BBQ).

Please take the time to look through this section and familiarise yourself with its contents. While it covers all the basic safety advice you might normally require, it is not a complete and authoritative representation of the law. If you require more detailed technical information, please contact us and our technical team will be happy to help.

LPG - Properties & Hazards

LPG - Properties & Hazards


LPG is liquefied petroleum gas and is:

  • Obtained during the processing of crude oil, or direct from the North Sea.

  • Colourless and odourless. An odourising agent is added before distribution to give its characteristic smell.

  • Half as heavy as water when in liquid form. It will float on water before vapourising.

  • Easily liquefied by pressure, taking up only around 1/250th of its gaseous volume. This means that a large amount of LPG can be stored in a small place.

  • Either commercial butane or commercial propane. These are similar in use but propane has a lower boiling point and hence a higher storage pressure. Commercial propane is predominantly an outdoor fuel, commercial butane is predominantly an indoor fuel.

Fire Precautions - Cylinders


Action in an Emergency

  • Sound the alarm and summon the fire fighting services.

  • Evacuate all personnel, except those necessary to deal with the emergency, from the danger area (particularly if in path of any cloud).

  • Always approach fire or leak from upwind and ONLY if safe to do so.

Cylinder Troubleshooting

Cylinder Troubleshooting

Forklift Truck Cylinders

If you have connected a new forklift truck bottle (18kg/12kg) and find that no gas is reaching the engine, it is probably due to the excess flow valve being shut. This valve is designed to stop the gas flow if it becomes excessively large eg. if the hose were to rupture. The valve can close accidentally if a cylinder has been connected and the cylinder valve is turned on suddenly, as this will result in a very high flow rate. This can be rectified by closing the cylinder valve, stopping the gas flow for a few seconds and allowing the excess flow valve to react. SLOWLY reopen the cylinder valve.

Butane Cylinders

If the ambient temperature approaches freezing, vapour will not pass through the regulator due to insufficient internal pressure. The cylinder should be taken to a warm room and allowed to warm up naturally for approximately 1 hour. Do not apply external heat to the cylinder (e.g. putting the cylinder next to a radiator or fire).

Transport of LPG Cylinders

Transport of LPG Cylinders

Basic Requirements

  • These requirements do not apply to the transport of LPG by private persons for personal or domestic use, however the basic requirements set out below should be followed.

  • Any vehicle used to transport LPG cylinders should:

    • Be suitable for the task, of adequate strength and in good condition.

    • Permit the cylinders to be transported in the upright position.

    • Be open (preferred) or have adequate ventilation.

  • Drivers and members of the vehicle crew are not permitted to smoke in or near any vehicle that is being loaded or unloaded with or transporting LPG cylinders. Means of ignition i.e. cigarette lighters, lanterns, portable cooking stoves, etc are not permitted to be carried or operated on or in the vehicle.

  • Appliances may be carried as long as they cannot be operated whilst they are on the vehicle and their carriage does not present a risk of ignition. Appliances that are boxed or packaged would comply with this requirement.

  • Apart from members of the vehicle crew no passengers should be carried (this is a legal requirement if transporting more than 333 kgs (Net) of LPG.

Cylinder Gas Storage

Cylinder Gas Storage

Small Storage/ Display (in shops etc/ up to 70kg)

  1. No more than five bottles should be allowed on display with total contents no more than 70kg.

  2. Bottles larger than 20kg should not be displayed in shops eg 47kg cylinders

  3. If the shop is below residential premises then no more than 15kg should be stored/ displayed.

  4. No more than four bottles should be connected for demonstrating at any one time (total weight no more than 50kg).

  5. Do not display on staircases, near emergency exits or near to flammable materials.

  6. Bottles must be treated as FULL unless they are dummy bottles or have been certified as gas free. Only five cylinders are allowed - even if some of them are empty.

Cylinder Handling & Use

Cylinder Handling & Use

General Advice

  • Do not store or use bottles in the horizontal position. A leak could be very serious and liquid could enter gas lines.

  • Do not drop bottles off vehicles or platforms, as damage to bottles and valves can be caused.

  • Always display safety and operating notices prominently.

  • Don't change or store bottles in the presence of naked flames.

  • Trace leaks using liquid detergent solution, NEVER a naked flame.

  • Never store or use below ground level, as any leakage will collect at low levels. Storage should be well ventilated, preferably outdoors.

  • Don't use tools to operate bottle valves.

  • Propane bottles should not be used indoors for domestic appliances, due to their higher pressure.

  • Always replace safety caps/plugs when the bottle is empty or not in use.

  • Check hoses regularly. Ensure properly secured with hose clips. If hoses are damaged or showing signs of wear, replace them (using hose of correct quality)

Regulator Selection

Regulator Selection

Propane bottles contain considerably greater pressure than butane cylinders. Cylinder regulators designed for use with either propane or butane are not interchangeable because of:-

  • Their different design pressure.

  • The dissimilar bottle valves for the two gases.
