Mandatory Sign - All Cylinders Must Be Chained

Yes, according to the Australian Standard AS 1319, Mandatory Signs are used to clearly communicate instructions that must be followed to ensure safety or compliance. These signs are often seen in workplaces, construction sites, and areas where specific actions are required to prevent accidents or harm.

Key Features of AS 1319 Mandatory Signs:

1. Symbol and Color: They must have a white symbol displayed within a blue disc. The blue disc provides a strong contrast to ensure high visibility.
2. Message: They usually contain the word "MUST" to emphasize that the action is not optional but compulsory.
3. Purpose: These signs are primarily used to ensure that people follow safety protocols, such as wearing protective equipment or following specific safety procedures.

Following this standard is essential in maintaining a safe working environment and ensuring that all individuals understand mandatory requirements.
