Mandatory Signs

Protect workers and visitors with high-visibility “mandatory” safety signs

In any workplace, safety starts with clear communication, and that begins with proper signage. A “mandatory” sign is essential in areas where specific actions must be taken to ensure the safety of employees, contractors, and visitors.

Unlike warning or prohibition signs, mandatory safety signs provide clear instructions that must be followed, such as wearing personal protective equipment (PPE), reporting incidents, or using specialised equipment. These signs are commonly found on construction sites, factories, warehouses, and other areas where hazards exist.

When safety precautions are non-negotiable, a required sign helps reinforce the seriousness of the situation. Whether you're managing a large industrial operation or a small workshop, the right “mandatory” signage can make all the difference in preventing injuries, accidents, and unnecessary exposure to risks.

Compliant with Australian Standards for workplace safety

Our “mandatory” signs align with Australian Standard AS 1319, which outlines the correct format for safety signage used in occupational environments. According to this standard, a compliant “mandatory” sign features a blue circular symbol on a white background, often with the word “MUST” to reinforce the action required.

We offer a wide range of “mandatory” signs, including:

• Hi-visibility jacket must be worn in this area
• Eye protection must be worn in this area
• Protective footwear must be worn
• Hearing protection must be worn in this area
• Masks must be worn in this area
• Respirators must be worn in this area
• Fall arrest equipment must be used.

These signs are essential across various industries, including construction, mining, logistics, manufacturing, chemical handling, and more. Wherever safety requirements exist, “mandatory” signs help ensure they are understood and followed.

If you want something specific, we can also design custom “mandatory” signs to suit your workplace. From unique instructions to specific PPE safety signs, we’ll work with you to create high-quality “mandatory” signs that are compliant, effective, and built to last.

“Mandatory” signage that’s built to last in harsh Australian environments

A safety sign is only effective if visible, so all our “mandatory” signage is made from strong, reliable materials designed to withstand demanding conditions. Choose from the following materials:

• Aluminium – Lightweight and corrosion-resistant, ideal for outdoor or indoor areas 
• Colorbond Steel – Durable and strong, perfect for construction sites or outdoor use
• Corflute – Cost-effective and lightweight, suitable for temporary or mobile signage needs
• PVC Foam Board – A sturdy indoor option with a clean, professional finish

We apply a free laminate coating to every sign to provide even more value. This helps protect against fading, cracking, and peeling, ensuring your “mandatory” signs remain readable for years, even in high-traffic or outdoor environments. Plus, you can choose between reflective and non-reflective options.

Support your workplace compliance with clear, consistent signage—from mandatory head protection to eye protection and beyond

Using the right safety signs isn’t just about ticking compliance boxes — it’s about creating a workplace where safety is second nature. Mandatory safety signs send a clear message: safety matters here, and precautions must be taken seriously.

By investing in high-visibility “mandatory” signage, you help:

• Improve compliance with legal and workplace safety standards.
• Reduce the risk of injuries, accidents, and incorrect PPE use.
• Provide employees and visitors with clear, consistent instructions.
• Ensure your site is prepared for inspections or safety audits.

From hard hat zones to eyewear requirements, our signs are designed to make safety second nature.

FAQs

What are PPE signs, and why are they important?

PPE signs are a type of “mandatory” sign used to indicate when personal protective equipment must be worn. These signs are crucial in environments where exposure to dust, noise, falling objects, or hazardous materials is likely. They help workers understand what safety gear needs to be carried or worn before entering a site, reducing the risk of injury and ensuring legal compliance. 

Their importance can’t be overstated — they’re a visual reminder that safety starts with the proper protection.

Where should mandatory construction signs be displayed?

Construction signs should be placed at all entry points and throughout the site, especially in high-risk areas. This includes zones where PPE is required, where heavy machinery is used, or where specific actions (like using fall arrest gear) are essential. Clear, well-positioned construction signs help prevent confusion, ensure workers and visitors are aware of potential hazards, and reinforce site safety rules.

Do I need different signs for employees and visitors?

Yes — it’s essential to consider your team and any visitors visiting your site. While workers are usually trained in site-specific safety procedures, visitors may not be. That’s why “mandatory” signs should be displayed prominently at entrances and throughout the site. This ensures that everyone, from full-time staff to delivery drivers and guests, knows the safety requirements and precautions they must follow.
