Warning sign - yellow triangle
Gas Signs
Gas needs clear signs: where cylinders are kept, where the emergency valve is, and what to do if you smell gas. These printable gas signs cover compressed gas, cylinders stored here, flammable gas, no naked flames, gas shut-off valve and an if-you-smell-gas notice. The if-you-smell-gas notice comes in two versions because the emergency number differs: 0800 111 999 for Great Britain and 0800 002 001 for Northern Ireland. Print in A5, A4 or A3 and fix them where they will be seen before anyone goes near the cylinders or the valve. For no smoking and fire signs, see the linked pages.

Questions
What should I do if I smell gas?
Open windows, avoid flames and switches, and call the National Gas Emergency Service. The number is 0800 111 999 in Great Britain. In Northern Ireland call 0800 002 001, and use the Northern Ireland version of the sign.
Is this sign for natural gas or bottled gas?
Both; choose the sign that matches your gas and your store.
Do I also need no smoking signs?
Usually; see the no smoking listing.
Can I rely on a sign for gas safety?
No. Gas work must be done by a Gas Safe registered engineer.
