What Are Mandatory Signs?

Mandatory signs instruct workers and visitors to perform a specific action or wear specific PPE in a designated area. They communicate ‘you must do this’ — as opposed to prohibition signs (you must not) or warning signs (be careful).

Under AS/NZS 1319-1994, mandatory signs use a blue circle with a white symbol. This standardised format gives instant recognition across all Australian worksites.

Common mandatory signs include: Hard Hat Must Be Worn, Hi-Vis Clothing Must Be Worn, Hearing Protection Required, Safety Glasses Must Be Worn, Safety Boots Must Be Worn, Safety Harness Must Be Worn, Wash Hands, and Authorised Personnel Only. Every mandatory sign in the NSS range is Australian-made. Order online today.

Frequently Asked Questions

What are mandatory signs and when are they required in Australian workplaces?

Mandatory signs instruct workers and visitors to perform a specific action or wear specific PPE. Under AS/NZS 1319-1994, mandatory signs use a blue circle with a white symbol. They apply wherever specific PPE or safety behaviours are needed to protect workers from identified hazards — hard hat signs in overhead hazard areas, hearing protection signs near noisy machinery, and safety glasses signs in chemical handling areas. WHS legislation requires every PCBU to communicate PPE requirements clearly. Mandatory signs are the AS 1319-recognised method for doing so. National Safety Signs supplies compliant mandatory signs for workplaces across Australia.

What colour are mandatory signs in Australia?

Under AS/NZS 1319-1994, mandatory signs use a blue circular background with a white symbol identifying the required action or PPE. This blue and white scheme applies consistently across all Australian workplaces. It separates mandatory signs from danger signs (red/black/white), warning signs (yellow/black), prohibition signs (red/white circle), and emergency signs (green/white). Blue in the safety sign system means ‘you must do this’. Workers and visitors recognise it instantly, regardless of language or literacy level.

Are hard hat signs mandatory on Australian construction sites?

Yes. Hard hat signs are mandatory on Australian construction sites and any workplace where overhead hazards exist. Under the Work Health and Safety Regulations and the model Code of Practice for Construction Work, head protection must be worn at all times in designated areas. Site managers and principal contractors must post mandatory PPE signs at all entry points and throughout zones where head protection applies. National Safety Signs supplies AS/NZS 1319 compliant hard hat mandatory signs in multiple sizes and materials.

What mandatory PPE signs do I need for a construction site?

A typical Australian construction site needs mandatory signs for: Hard Hat Must Be Worn (all work areas), Hi-Vis Clothing Must Be Worn (all areas), Safety Boots Must Be Worn (all areas), Hearing Protection Required (near noisy plant and equipment), Safety Glasses Must Be Worn (grinding, cutting, and chemical areas), and Safety Harness Must Be Worn (working at height areas). Site-specific hazards may require additional signs. National Safety Signs can supply a complete mandatory sign package — contact our team for a quote.

Can I order custom mandatory signs with specific PPE requirements?

Yes. National Safety Signs prints custom mandatory signs with your specific PPE requirement or instruction, maintaining full AS/NZS 1319 compliance in colour, layout, and format. Custom signs suit non-standard PPE requirements specific to your site or industry — for example, ‘Chemical Resistant Gloves Must Be Worn’ or ‘Face Shield Required Beyond This Point’.
