Arc flash incidents and electrical shock can cause severe burns, serious injury and damage to equipment, making clear hazard identification essential around energised electrical systems. A Warning – Arc Flash And Shock Hazard Sign provides an immediate visual reminder that electrical hazards may be present and that workers, contractors and authorised personnel should approach the area with appropriate caution.
Positioning this electrical warning sign near switchboards, electrical panels, control cabinets, substations and other high-voltage equipment helps alert people before they enter or work near a potentially hazardous zone. Clear signage can support safer work practices by increasing awareness of arc flash risks, electric shock hazards and the need to follow established site procedures before inspection, servicing or maintenance activities begin.
This arc flash warning sign is suitable for a wide range of Australian workplaces, including factories, warehouses, mining operations, construction sites, commercial buildings, manufacturing facilities, utilities, workshops and industrial plants. It can also be used in plant rooms, electrical rooms and restricted service areas where personnel may encounter live electrical equipment.
Sign Portal manufactures each sign in-house using premium materials and high-definition UV printing for sharp text, strong visibility and a professional finish. Designed for both indoor and outdoor use, the sign is made to withstand demanding Australian conditions, including exposure to sunlight, weather and busy industrial environments.
Standard sizes are available for convenient installation, while custom sizes, materials, wording and designs can also be produced to suit individual site requirements. Improve hazard awareness throughout your workplace with clear, durable electrical safety signage that helps workers recognise risks quickly and supports a safer working environment.

FAQ
Safety signs questions
What materials are best for outdoor safety signs?
For outdoor applications we recommend Aluminium Sheet, Aluminium Composite Material (ACM) or Polypropylene, depending on the environment. Solid aluminium provides the highest level of durability and corrosion resistance, ACM offers an excellent balance of strength, weight and value, while polypropylene is ideal for temporary outdoor signage where a lightweight solution is required.
What materials are best for indoor safety signs?
Foam PVC and polypropylene are popular choices for indoor safety signs because they are lightweight, cost-effective and provide excellent print quality. They are commonly used in warehouses, offices, schools, factories and commercial buildings.
What is the difference between ACM and solid aluminium?
Aluminium Composite Material (ACM), sometimes referred to as ACP, consists of two thin aluminium skins bonded to a polyethylene core. It is lightweight, rigid and widely used throughout the signage industry. Solid aluminium is manufactured from a single sheet of aluminium, making it more impact resistant and better suited to harsh outdoor environments, coastal locations and applications requiring maximum longevity.
Which material is the strongest?
In terms of strength and durability the general order is: Solid Aluminium, Aluminium Composite Material (ACM), Foam PVC and Polypropylene. The best material ultimately depends on the environment, expected lifespan and installation method.
Why should I choose reflective safety signs?
Reflective safety signs improve visibility during low-light conditions by reflecting light back towards its source. They are commonly used for regulatory signage, traffic management, construction sites, car parks, emergency exits and locations where signs need to remain visible at night.
Do your reflective safety signs comply with Australian Standards?
Our reflective materials are available in grades manufactured to meet the requirements of AS/NZS 1906.1:2017 for retroreflective materials where applicable. If your project requires a particular reflective classification, please let us know and we can recommend the appropriate material for your application.
Why can I see lines on some reflective signs?
Engineering Grade (Class 100) reflective material has a smooth appearance with no visible prism pattern. Higher-performance prismatic reflective materials, such as Class 400 and Class 1100, contain microscopic prisms that may be visible when viewed up close. This is a normal characteristic of the material and contributes to its increased reflectivity.
Which reflective grade should I choose?
Class 100 is suitable for general commercial and private property signage where good night-time visibility is required. Class 400 (or 400T) provides significantly higher reflectivity and is commonly used for public road signage and traffic management. Class 1100 offers the highest level of retroreflectivity for critical road safety applications including highways, intersections and high-speed environments.
Can I use any reflective sign on public roads?
No. Road authorities may specify minimum reflective grades, colours, sizes and sign designs. Requirements vary between states, councils and project specifications. Always confirm the required standard with the relevant road authority before purchasing.
Do you manufacture custom safety signs?
Yes. Sign Portal manufactures custom safety signs in-house. We can produce virtually any size, material or design, including company branding, site-specific information, custom wording and logos.
What fixing options are available?
Our safety signs can be supplied with pre-drilled holes, rounded corners, adhesive backing, cable tie holes or left blank depending on your installation requirements.
How long will my safety signs last?
The lifespan depends on the material, installation location and exposure to weather. Solid aluminium and ACM signs can provide many years of outdoor service when correctly installed, while indoor materials such as Foam PVC provide excellent longevity in protected environments.
Can you help me choose the right material?
Absolutely. If you're unsure which material best suits your application, our experienced team can recommend the most appropriate option based on your location, budget, installation method and expected lifespan.
Do your safety signs comply with Australian Standards?
Many safety signs are designed to align with the relevant Australian Standards; however, the applicable requirements vary depending on the type of sign and its intended use. If your project requires compliance with a particular Australian Standard or industry specification, please let us know so we can recommend the appropriate product.
Do I need approval before installing safety signs?
Some regulated environments, roadways and workplaces may require specific signage, sizes or installation methods. We recommend checking the applicable workplace, council or regulatory requirements before installation where compliance is mandatory.
