Safety signs are mandatory signs installed especially in work places so that employees are adequately warned if any danger takes place. Such signs help all employees to be aware of any potential danger and help them to either avoid such situations or be able to react quickly if caught in a dangerous situation. It is the duty of the employer to install relevant safety signs on the business premises.
Different types of mandatory signs
Mandatory signs should cover information on health and safety. Means of displaying such signs could be - posted on a signboard – an acoustic signal – a hand signal – even verbal communication.
Why are safety mandatory signs used

Employers' responsibility
In spite of making mandatory signs as clear and visually effective as possible when put up in the workplace, employers have the responsibility of explaining the meaning of these signs to the staff. This is in the event any calamity does take place, then the staff will now how to react quickly.
Supplementary signboards
Sometimes a supplementary signboard is used in the workplace. This type of signboard could have some text included, mainly to enhance its clarity. Signboards are normally printed on what is known as a 'carrier'. The carrier can be made of plywood, metal, plastic – or any other material which is suitable to the location where it is displayed.
Including text on mandatory signs
In years gone by including text on signs was allowed. However, since 2007 a rule has been passed that usage of text would not be allowed. However in the case of supplementary signboards, text could be used but with strictures that such text should not adversely impact the safety aspect of the signboard.

In the workplace, some of the common signs read 'workmen overhead', 'no tresspassing' 'fire' signs etc. The pictures depicting these signs need to be very clear and the message implied should be unambiguous.
