Warn workers of hot surfaces and steam with this AS 1319-compliant caution sign. The yellow and black format is instantly recognisable and meets Australian safety standards for hazard communication. Available in corflute, polypropylene, Colorbond, and vinyl in four standard sizes from 225×300 mm to 600×900 mm. Our fade-resistant inks maintain visibility through extended UV exposure and temperature fluctuations common in industrial settings. Pre-drilled holes, lamination, and reflective Class 1 or Class 2 overlays are optional add-ons to suit your mounting method and lighting. Trade customers enjoy bulk pricing; Australia-wide delivery takes 5–7 business days.
Final sign type, wording, size, placement and material depend on the site risk, project specification and applicable jurisdiction. Confirm the requirement with the relevant WHS adviser or regulator.

Frequently asked
What surfaces should display a 'Caution Hot' sign?
Pipes, boilers, steam vents, heated presses, ovens, and exhaust manifolds all warrant this sign. Place it within 30 cm of the hot surface so workers notice it before contact.
Is a larger sign always better for visibility?
Not necessarily. Choose size based on viewing distance: 225×300 mm for close work areas, 300×450 mm for general workshops, 450×600 mm for warehouse aisles, and 600×900 mm for open yards. Oversizing wastes material and cost.
Do reflective coatings work around hot surfaces?
Reflective grades provide different visibility performance. Choose the grade required by the project specification and site conditions, and confirm any road, traffic or high-risk requirement with the relevant authority before ordering.
Can I use corflute near steam or high-humidity areas?
Not recommended. Corflute absorbs moisture and can warp or delaminate. Choose polypropylene or vinyl for steam rooms, kitchens, and other damp environments.
How often should I replace a worn 'Caution Hot' sign?
Replace when text becomes illegible, colours fade significantly, or the sign shows physical damage. Laminated signs last longer; inspect annually and replace every 3–5 years depending on environment.
