Gas Cylinder Storage Regulations
Storing gas cylinders safely is a legal duty. This is a plain overview of the principles behind gas cylinder storage regulations — not legal advice.
In practice
Stored to the right standards
Ventilated, upright, secured and segregated — the basics that keep cylinder storage safe and compliant.
Risk kept off your site
No suitable space of your own? Our third-party storage takes the compliance burden away from your premises.
What safe cylinder storage requires
Good cylinder storage comes down to a handful of principles applied consistently. Get these right and most of the risk is controlled.
- Ventilation — store in a well-ventilated area, ideally outdoors, so any leak disperses.
- Upright and secured — cylinders stood upright and restrained against falling.
- Segregation — incompatible gases (for example oxidisers and flammables) kept apart.
- Ignition control, security and signage — away from heat sources, access-controlled and clearly signed.
Where cylinders should be kept
Outdoor, ventilated storage is generally preferred because a leak disperses safely. Indoor storage is not ruled out, but it has to work harder to be safe.
- Outdoors: ventilated, secured and shaded from extreme heat.
- Indoors: only with adequate ventilation, segregation and fire-safety measures.
- Empty cylinders: treat as if they still contain gas — residual pressure remains.
What safe storage looks like
Good cylinder storage is well-ventilated (ideally outdoors), keeps cylinders upright and secured, segregates incompatible gases (e.g. oxidisers from flammables), restricts ignition sources, and is signed and access-controlled.
- Store upright, secured against falling, in a ventilated area.
- Segregate flammable, oxidising and toxic gases appropriately.
- Keep away from heat/ignition; control access and sign the area.
For businesses without suitable space, Adams Gas offers third-party storage.
Storage, managed for you
Tell us what you hold
Let us know the gases, cylinder types and rough volumes you need stored so we can plan suitable, segregated space.
We store it compliantly
Your cylinders are held off-site to the right standards — ventilated, secured, segregated by gas and access-controlled.
Call it off when you need it
Stock is made available when you want it, keeping the cylinders, the space and the handling risk off your own premises.
Frequently asked questions
Can cylinders be stored indoors?
Outdoor, ventilated storage is preferred. Indoor storage must meet ventilation, segregation and fire-safety requirements.
How should different gases be segregated?
Keep incompatible gases apart — for example oxidisers away from flammables, and toxic gases separated. Grouping by hazard is the single most important storage control.
Do empty cylinders need safe storage too?
Yes — treat empties as if they still contain gas. They retain residual pressure and should be stored upright, secured and ventilated like full cylinders.
Can Adams Gas store cylinders for me?
Yes — our third-party storage holds and manages cylinders off-site to the right standards, useful where you lack suitable space.
