    Really effective warning sign. The red “Danger” header is very striking, and the additional messages are very readable from a distance. Delivery was slightly slower than I expected, but the quality makes up for it. Minor point: I’d like a slightly more weatherproof finish for long-term outdoor use.

    Top class sign. The layout is well thought out - the red danger section draws attention, while the detailed text beneath is unambiguous. The board is tough but not overly heavy, which made mounting simple. Since it went up, I feel much more confident that visitors understand the risk. Five stars!!!!!

    Bought this for our workshop where we store flammable liquids. The multi-message design is ideal — we don’t need separate signs for each warning. Print is super sharp, and the board hasn’t started deteriorating despite being outside. Exactly what we needed for compliance and safety. Excellent.

    This has helped us reinforce a very serious hazard clearly. The sign is big enough to be noticed, but not too large to dominate. It’s well made, though I knocked off a star because I had to source my own fixings — if it came with better mounting hardware, that’d be perfect.

    This sign is absolutely excellent - the “Danger – Flammable Vapour” warning is very bold, and the “No Smoking / No Naked Lights” messages are clearly laid out. We put it at the entrance to our fuel-storage area and it’s already stopped people making risky mistakes. The material feels very robust, even in damp weather. Really well made.
