Prohibition Signs: The Art of Saying "NO"

What defines a Prohibition Sign?

These are the "Strict Parents" of the signage world. They legally forbid behaviour that is likely to cause a risk to health and safety.

Technical Spec (ISO 7010):

  • Shape: Round.
  • Colour: White background, red circular band, and a red diagonal crossbar.
  • Meaning: "Do Not," "No Access," "Stop."

Top Sellers:

  • No Smoking / No Vaping: Essential for compliant workplaces.
  • No Entry / Authorised Personnel Only: Keep people out of the server room or the warehouse.
  • No Mobile Phones: Because forklifts and texting don't mix.

Viking Tip: Don't be polite with these. You don't need "Please No Entry." You need a big red crossed-out circle that says "No Entry." We print them sharp and bright so they can’t be ignored.
