About the sign
A no smoking or naked flames sign displays the familiar red prohibition symbol alongside clear text, leaving no room for misunderstanding. You will find it in fuel storage areas, workshops, plant rooms, and anywhere flammable materials or gases are present.
A well-placed sign communicates the hazard at a glance, even to visitors who are unfamiliar with the site. Keeping the message visible and legible reduces the chance of an oversight that could have serious consequences.

Questions and answers
Where is a no smoking or naked flames sign typically displayed?
It is most commonly used near fuel tanks, gas cylinders, paint stores, boiler rooms, and other areas where flammable substances are stored or handled.
Can I use this sign outdoors?
Yes. The outdoor option is finished with a UV laminate that protects against weathering, so it stays legible in exposed locations.
What is the difference between the sticker and the rigid sign?
The sticker is a laminated self-adhesive option suited to smooth indoor surfaces. The rigid PVC sign is more durable and can be screwed or fixed to a wall, door, or post.
Can I change the wording on the sign?
Yes. Use the AI designer in the chat to adjust the text, and the design will update to reflect your changes before you order.
Which size should I choose for a large warehouse or storage area?
For a large open space, a bigger format ensures the sign is readable from a distance. The viewing distance information on this page will help you decide.
