What does this sign mean?
A warning (yellow) sign used when no specific ISO symbol describes the hazard closely enough. The exclamation mark inside a yellow triangle with a black border is ISO 7010 W001 and means 'take care, there is a hazard here'; it only does its job when a line of text names the hazard.
Where does it go and when is it required?
Placed at the entrance to areas with mixed or temporary hazards: maintenance work, floors left wet after cleaning, loading bays behind shops, warehouses and plant rooms. Civil Defense inspectors expect it wherever a visible hazard is not already covered by a more specific sign.
Regulation notes: Civil Defense inspectors in Saudi Arabia and the UAE expect every visible hazard inside a facility to carry a clear warning sign when an operating licence is issued or renewed, and missing warning signage is a common reason for a delayed approval. In the UAE, OSHAD Code of Practice 17.0 requires Arabic to sit above English on safety signs.
- Mount at eye level (1.5–1.7 m) at the entrance to the hazardous area rather than inside it, so people read it before they step in.
- A4 is enough indoors and in corridors; use A3 at site entrances and wherever it has to be read from a distance.
- Add a line under the triangle naming the hazard, 'wet floor', 'maintenance in progress', and take temporary signs down as soon as the hazard clears, so staff never learn to ignore them.
This sign is also known as: general warning sign, general warning sign printable pdf, ISO 7010 W001 sign, caution triangle sign Arabic English. Shape and colours follow ISO 7010 / ISO 3864-1, reference W001.
