Overview
The short answer, then the detail.
A Caution sign gives people clear information where they need it. It uses the ISO 7010 W001 general warning sign symbol. Choose 3mm Foamex, 3mm Dibond aluminium composite and self-adhesive vinyl in sizes from A4 (210 x 297 mm) to A1 (594 x 841 mm); the largest reads at about 24 metres. Free standard UK mainland delivery, no VAT added.
This Caution sign gives people clear information where they need it. It is typically used in offices, shops, warehouses and public buildings. The design uses a yellow warning triangle with black text, with the ISO 7010 W001 (General warning sign) symbol.
The CAUTION header flags a hazard people need to look out for; the text underneath says exactly what it is.
The legal background: the Health and Safety (Safety Signs and Signals) Regulations 1996 require employers to provide a safety sign where a risk cannot be avoided or controlled by other means. Warning signs use a yellow triangle with a black border.
You can have it printed on 3mm Foamex (rigid PVC foam board), light and easy to fix indoors or for short-term outdoor use, 3mm Dibond aluminium composite, rigid and weatherproof for long-term outdoor use and self-adhesive vinyl for smooth walls, doors, glass and equipment. Indoors, Foamex or vinyl is usually all you need.
Choosing a size: we allow about 1 metre of viewing distance for every 25mm of sign height, based on the distance-factor method in ISO 3864-1. That gives A4 (210 x 297 mm) (reads at about 8 m), A3 (297 x 420 mm) (reads at about 12 m), A2 (420 x 594 mm) (reads at about 17 m), A1 (594 x 841 mm) (reads at about 24 m).
Where to put it: At eye level where people will act on it.

Which size do I need?
A safety sign must be large enough to read from where people will see it. Our conservative guide, based on the distance-factor method in ISO 3864-1, is about 1 metre of viewing distance for every 25 mm of sign height (the shorter side). Use it with your own risk assessment.
| Size | Readable from up to about |
|---|---|
| A4 (210 x 297 mm) | 8 m |
| A3 (297 x 420 mm) | 12 m |
| A2 (420 x 594 mm) | 17 m |
| A1 (594 x 841 mm) | 24 m |
Well lit or internally lit signs can be read from further away; dim areas need larger signs.
