How to Store Gas Bottles Safely

Knowing how to safely handle compressed gas storage bottles is crucial. Many industries use different types of bottled gas for a variety of purposes, but in the end the risk they pose is the same.

Every year thousands of gas bottle-related accidents occur in workplaces across the country and many factors can contribute to this. These include poor staff training, incorrect installation and inaccurate filing procedures when handling sensitive compressed gas bottles.

Keep reading this quick and handy guide for an efficient overview of how to store and handle gas bottles safely, as well as all the up to date legal guidance surrounding this issue.

How should gas bottles be stored?

Gas bottles should be stored in well-ventilated places, away from areas where there could be possible ignition sources. This is incredibly important for two reasons:

  1. By storing the gas bottles in well-ventilated and preferably outdoor areas you are decreasing the risk of build-up in the case of a leak, which can have devastating impacts on the environment and wildlife.
  2. Keeping your gas bottles away from possible ignition sources is vital to avoid extremely damaging consequences, including possible explosions. Always keep gas bottles far away from naked flames.

Gas bottles should always be stored in a vertical position to reduce the chances of harmful gas leaks and very messy spillages. Chains or other appropriate securing measures should also be used to keep the bottles in place and prevent them from toppling over.

Do empty and full gas bottles need to be stored separately?

Yes, they do. Empty gas containers should be stored in a separate area (or gas bottle cage) away from full ones to avoid confusion. However, regardless of whether they are full or empty, gas bottles which have (or had) the same contents should always be grouped together to prevent any mix-ups.

How do I know if a gas bottle is empty?

All gas bottles are labelled with all the necessary information you require, including the tare disk weight. To check how much gas you have left if your bottle, or if it's empty, you simply need to weigh it. For example:

The total weight of a gas bottle is 25kg – the bottle weighs 13kg and the gas itself weighs 12kg. If you want to check how much gas is remaining place the bottle on a scale and if they show 14kg and the original bottle weight was 12kg, this would mean there is 2kg of gas left in the bottle.

On certain varieties, the window on your changeover unit will display a red colour indicator if your cylinder is empty.

With this being said, an LPG gas cylinder might seem empty, but could still contain LPG vapour – so you should treat all LPG gas cylinders as if they were full.

What are the legal requirements surrounding gas bottle storage?

There are certain guidelines outlined by HSE which should be followed for maximum safety for yourself, your staff and any equipment you have in your workplace. These include:

  • The maximum size of any LPG cylinder stack should not exceed 30,000kg
  • Cylinders should be stored preferably in the open air on a concrete or load-bearing surface
  • Containers should be stored with their valves uppermost
  • For storage indoors, no more than 5000kg may be stored in each purpose-designed building compartment and;
  • A maximum of five compartments may exist in a single building.

The BRITISH COMPRESSED GASES ASSOCIATION (BCGA) also outlines some recommended minimum requirements for how to handle gas cylinders including:

  • All personnel shall wear appropriate PPE
  • Cylinders shall not be rolled along the ground; this may damage or even open the valve and will also damage identifying labels, marks and symbols
  • A cylinder shall not be moved with the valve open

Top tip: The Manual Handling Operations Regulations (3) require first that an assessment of manual handling operations is conducted. Following the assessments, training should take place. Where the assessment indicates that the work exceeds guideline limits, wherever practicable the operation should be mechanised or handling aids provided.

Which type of signage is required on gas bottles?

Compressed gas cylinders are required by law to carry and display hazard warning signs and Control of Substances Hazardous to Health (COSHH) warning symbols to minimise the risk of injury.

It is also important to ensure you can clearly identify which cylinders are full and which cylinders are empty. Empty cylinders should be marked as such as full and empty cylinders require a different level of care and handling.  

Our top Gas Bottle Storage tips

No matter what industry you are working in, if you keep compressed gas cylinders on site it is vital to ensure you have taken all of the proper safety precautions. Here is a reminder of the key points to ensure you have implemented the appropriate safety measures when storing gas cylinders:

  • Don’t use gas cylinders in the horizontal position – in the event of a leak use detection fluid to trace it
  • Don’t change gas cylinders in the presence of naked flames
  • Always display safety and operating notices prominently
  • Always store cylinders in accordance with legal requirements
  • Never store below ground level, as any leakage will collect at low levels
  • Don’t use tools to operate gas cylinder valves – these should be firmly tightened or opened by hand only.
