Safety signs express a generally understandable safety message. It is given by the colour, shape of the mark and graphic symbol (pictogram). Safety information may be specified by verbal communication.
The purpose of these signs is to alert employees at construction sites to various risks associated with dangerous places where these people work.
Clear instructions are conveyed through signs that display symbolic representations or pictograms in white on a blue circular background. To further enhance the clarity of the message, some signs may also contain black lettering on a white background. These signs are designed to be easily understood and followed, ensuring everyone can navigate their surroundings safely and efficiently.
When specific actions or behaviours are prohibited, you may encounter signs that indicate this. These signs are easily recognisable by their red circle with a black action symbol inside, which is slashed to show that the depicted action is not allowed. Sometimes, additional wording in black letters on a white background may be added to clarify the prohibited activities.
It is essential to be aware of the signs that indicate the location of emergency-related facilities, such as fire exits, first aid points, and health and safety signs. These signs are easily identifiable by their white symbol and text on a green background. Knowing where these facilities are can help ensure the safety of everyone in the area during an emergency.
These signs notify individuals of potential hazards or hazardous situations that, while not necessarily life-threatening, still require caution. The signs typically feature a striking black hazard symbol enclosed by a vibrant yellow triangle, universally recognised as a symbol of caution and danger. If the situation calls for it, the sign may include additional text in clear black lettering against a bold yellow background to emphasise the warning further.
These signs aim to alert people of a possible danger that could be life-threatening or pose a hazardous situation. They typically display the word "Danger" enclosed in a red oval shape within a black rectangular frame.
