Signs
3. Other signs
Signs with different features to those mentioned previously are employed in some particular cases to highlight certain hazards.
We shall now see what these situations are and the signs to use in each case.
3.1. Risk of falls, knocks and hazardous areas
When differences exist in heights, obstacles or other elements that might give rise to the risk of a person falling, knocking into or being hit by objects, panel signs or a safety colour may be used, as well as cordoning off the area.
Hazardous areas or areas with limited access in which there is a risk of people falling, objects falling, knocking into or being hit by objects, are to be identified by means of a safety colour.
In both cases, signalling by means of colours is to be carried out using alternating yellow and black stripes at an angle of 45º, as in the following figure:
3.2. Roadways
Whenever necessary, in order to protect workers, roadways are to be clearly demarcated by means of continuous stripes in a plainly visible colour, preferably white or yellow, taking into consideration the colour of the ground.
The demarcation should respect the necessary safety distances between vehicles and nearby objects and between pedestrians and vehicles.
3.3. Works entrances and perimeter
Signposting, which is mandatory, is to be carried out by means of pennants, ropes, metal or plastic nets or mesh, or demarcation tape, etc., in such a way that these are clearly visible and identifiable.
