Warning sign - yellow triangle
Danger Signs
Danger signs mark places where the risk is serious. These printable danger signs follow the familiar yellow triangle layout, or give you a plain red 'Danger' notice when you want maximum impact. Choose from electric shock risk, confined space, deep excavation, authorised personnel only and more, each in A5, A4 and A3 and both orientations. Keep out signs, high voltage signs and poison signs have their own pages, linked below, because their symbols and wording are different.

Print tips
- Print at "actual size" or 100%, not "fit to page", so the margins stay even.
- Use thicker paper or card (160gsm or more) if the sign will be handled.
- For outdoor or long-term use, laminate it or buy a rigid version.
Where to use it
- Plant rooms and switch rooms (with an electrical sign)
- Confined spaces, tanks and pits
- Excavations and trenches on private sites
- Gates to hazardous areas, with a keep-out sign
- Anywhere you want a strong, simple warning
Questions
What is the difference between danger, warning and caution?
Danger suggests the most serious risk, caution the least. The words are not a legal scale.
Which danger sign for electricity?
Use the electric shock sign here, or the high voltage and electrical warning pages linked below.
Should the sign say who may enter?
If entry is restricted, add an authorised personnel sign or a keep-out sign next to it.
Do these signs replace permits or barriers?
No. A sign supports other controls such as permit-to-work, barriers and locks.
