The installation of safety signage is mandated by the Health and safety at work act 1974. Safety signs must be provided and maintained in circumstances where a health and safety risk or hazards are identified.
Mandatory safety signs consist of:
- Warning signs (warning of a hazard) – triangular signs with black pictogram and yellow background.
- Prohibition signs (prohibits an action) – round shape with black or white pictogram and either red edgings or a diagonal line.
- Mandatory action signs (prescribes specific behavior) – round shape with white pictogram and blue background.
- Emergency signs (information for emergency situations) – rectangular or square shape with white pictogram and green background.
- Fire safety signs (information for fire emergency) - combination of warning and emergency signs.

 Identification and wayfinding signs
Wayfinding signage can provide direction to a particular room or area and is important in large, complex buildings such as hospitals, educational facilities or transport terminals. In such cases, a uniform house style is considered desirable for consistency and clarity.
 Branding and advertisement
Effective wayfinding can not only produce a safer environment, it can also create a positive impression. The location and design of identification and wayfinding and other signage forms a major part of an organisation’s corporate image and may be specified in some detail by in-house design guides.
 Instruction and prohibition signs
Signage in buildings may also instruct users to behave in certain way (‘please knock before entering’) or prohibit them from undertaking certain activities (‘no eating or drinking’). This may reflect an organisation’s internal policies, such as prohibiting the use of mobile phones in certain areas.
