Warning Dangerous Site – Keep Out Signs | Hazard Signs
Product Summary
Protect your construction site or hazardous zone with our high-visibility Warning Dangerous Site – Keep Out Signs. Designed to clearly communicate that unauthorized access is prohibited, these signs play a critical role in preventing accidents and ensuring compliance with health and safety regulations. Whether you're managing a construction project, industrial facility, or restricted access area, these signs help enforce safety protocols and limit liability by warning individuals of potential risks.
Featuring bold lettering and universally recognized hazard symbols, these signs are part of our comprehensive range of hazard signs—ideal for use alongside other safety signage such as a danger sign, high voltage sign, toxic hazard sign, biohazard warning, or slippery surface sign. Ensure your site is fully covered with clear, concise messaging that reinforces safety boundaries.
Material & Print Options
Our Warning Dangerous Site – Keep Out Signs are available in two durable material options to suit various site conditions:
- Adhesive Vinyl: A flexible, self-adhesive option ideal for smooth indoor surfaces such as doors, walls, or windows. Easy to apply and suitable for temporary or semi-permanent use.
- 3mm Rigid PVC: A robust, weather-resistant plastic that delivers excellent performance in demanding outdoor environments. Ideal for long-term use on fences, hoardings, and site entrances.
All signs are printed with UV-resistant inks to maintain readability and vibrancy, even in harsh weather conditions. Graphics and text are designed for maximum legibility from a distance.
Installation Info
These signs are supplied without fixings, giving you the flexibility to choose the most suitable mounting method for your site. Depending on the surface and location, you can use cable ties, screws, nails, or adhesive pads (not included). Our rigid PVC option can also be drilled for custom fixings—perfect for installing on gates, fences, or hoarding panels.
For adhesive vinyl signs, simply peel and stick onto a clean, dry surface for a secure hold.
