Answer

Safety signs are designed to an international standard to include shape and colour. The following colours are used:

Red indicates prohibition, often related to fire safety or emergencies, signaling actions that should not be taken.
Yellow serves as a caution to alert individuals to possible dangers or hazards in the area.
Green signifies a positive action, denoting safe conditions or first aid locations.
Blue denotes mandatory actions or information signage, indicating requirements that must be followed.

The standardization of these colour codes allows workshop users to be aware of hazards in the workplace, promoting safety and efficiency.
