Gas cylinders as we are all aware are handled and stored in accordance with the environment that the gas cylinder is placed in.

Many accidents can be caused by the inappropriate storing of gas cylinders, so how do you store gas cylinders in confined spaces and what size of gas cylinder could be right for you?

Martek Marine are specialists in providing, dispatching and supporting businesses in the Marine Industry with gas products and services and our team has provided you with a small guide on 4 Reasons to Consider Your Gas Cylinder Size.

Storage – Where space is at a premium

It’s true to say that the space made available on a ship is maximised as there are so many components, however, when it comes to storing gas cylinders you must be selective on the size and how the cylinders are safely contained.

What you must consider when storing gas cylinders:

  • Allow cylinders to be stored under cover, preferably enclosed and not subjected to extremes of temperature
  • Be kept dry, clean and well ventilated (both top and bottom)
  • Have good access to delivery vehicles and reasonably level floor areas
  • Be large enough to allow for segregation of full and empty cylinders and permit separation of different medical gases within the store
  • Be totally separate from any nonmedical cylinder storage areas
  • Be sited away from storage areas containing highly flammable liquids and other combustible materials and any sources of heat or ignition
  • Have warning notices posted prohibiting smoking and naked lights within the vicinity of the store
  • Be secure enough to prevent theft and misuse

As you can see from the above list, gas is given enough room to breathe and contained well enough to ensure that no accidents happen in transit. However, if your vessel is struggling to cope with the demands of health and safety and/or you require just that little bit more space to manoeuvre there are different size gas cylinders available.


When mixed and or stored/transported to and from destinations, the gas must be transported in a safe and controlled manner.

Here are some typical examples you must consider:

  • Compatibility of gas with the storage device (materials that the cylinder is made of)
  • Compatibility of gases stored or transported together (chemical reactions between the gases in the case of leakage of both or when involved together in fire what may be the consequences)
  • Compatibility of gas with other goods
  • Any other safety concerns

Transporting gas cylinders full or empty is still a major safety concern, by using the correct type and size of gas cylinder avoids potential problems further on.

Aluminium or Steel – What is Better?

Gas cylinders are primarily made of 2 types of metals, Aluminum and Steel and come in different sizes.

The choice you have depends on the gas type stored within the cylinder Reactive Gas and Non-Reactive Gas.

For Non- Reactive Gases steel cylinders have major advantages; as an example, a 103L steel cylinder is more cost effective as you can actually double the amount of gas added to the cylinder making your gas more efficient for your needs.

Our Top Reasons Simplified…

As you can see from the list above there are lots of factors when considering your gas cylinder size, however, we like to make things easy and recommend you think about the following when placing your next order of gas.

  • How much gas volume do you require?
  • What is the gas mixture and how will that impact gas volume?
  • The shelf life of the gas
  • Whether or not your staff need to move the cylinders
