Hazard Warning Signs

These signs should be used to make people aware of a nearby danger.

For example, a flammable liquid store or a laboratory where radioactive substances are in use, should have an appropriate warning sign near the entrance.

Signs warning of a particular hazard consist of a black band in the shape of an equilateral triangle. The background within the band should be yellow with the pictogram indicating the type of hazard in black positioned centrally on the sign.
