Definition
Safety signs use internationally standard colours and symbols: red for prohibition and fire equipment, yellow for warning, blue for mandatory actions such as wearing a helmet, and green for emergency exits and first aid. They go at entrances, hazard zones and equipment.
Why it matters on a project
They get instructions across quickly to workers of many nationalities and languages. Old or excessive signs get ignored.
Measurement and pricing
By number for each type and size within safety costs.
Common mistake
Hanging generic signs everywhere with no link to the real hazard in the area, so they lose their value.
Frequently asked questions
What language should safety signs use?
Standard symbols matter more than text, with Arabic, English and the main workforce languages where needed.
How often are signs reviewed?
With routine inspections and whenever the work area or hazards change.
