Mandatory signs and prohibited signs (EN ISO 7010:2020 compliance) are two types of safety signs used in workplaces to communicate important safety information to employees. However, they differ in their message and the actions required from individuals.
Mandatory Signs
Mandatory signs demand and require specific behavior from individuals using particular equipment, or while passing through an area. They are used to convey that a certain action is necessary in a particular location or situation, to ensure the safety of the individual or those around them. Mandatory signs are often in blue and white combinations, with a circular shape indicating the action that must be taken. These signs must be followed at all times to ensure a safe environment, and failure to follow them may result in accidents or injury. Examples of mandatory signs include “safety goggles must be worn” or “body harness must be worn” on construction sites.
Prohibited Signs
In contrast to mandatory signs, Prohibited signs indicate that a specific action or behavior is forbidden in a particular area or situation, and encourages an individual to avoid the action. These signs are used to convey potential hazards arising out of any specific activities or behaviors. Prohibited signs usually have a red, black, and white combination, and are generally circular or triangular and have a diagonal slash across the image to indicate what is not allowed. Examples include “no smoking,” “no eating or drinking,” and “no entry without permission.”
In summary, while mandatory signs and prohibitory signs appear similar, they serve different purposes. Mandatory signs indicate the necessary action required for safety, while prohibitory signs emphasize the actions that need to be avoided to ensure safety. To promote a safe and secure workplace environment, it’s essential to pay attention to the information on mandatory and prohibited signs and adhere to them closely.
