Danger Highly Flammable LPG/No Smoking Outdoor Signs | Flammable Signs
Product Summary
Protect your workforce and comply with essential safety regulations using our Danger Highly Flammable LPG/No Smoking Outdoor Signs. Designed for use in high-risk environments such as construction sites, industrial zones, fuel storage areas, and facilities handling volatile substances, these hazard signs provide a clear and immediate visual warning of flammable gas presence and the strict prohibition of smoking or open flames.
As a critical component of your site’s safety signage system, these signs serve a dual purpose: warning personnel about the presence of highly flammable LPG and reinforcing the no-smoking policy to prevent ignition risks. The use of bold hazard iconography and high-contrast colours ensures maximum visibility and rapid recognition, even from a distance. Whether you're managing a temporary construction zone or a permanent industrial site, this danger sign helps reduce accidents and supports best-practice safety protocols.
Material & Print Options
To suit a variety of indoor and outdoor applications, our Danger Highly Flammable LPG/No Smoking Outdoor Signs are available in two durable materials:
- Adhesive Vinyl: A flexible, self-adhesive option ideal for smooth, clean surfaces such as metal, glass, or painted walls. Quick to apply and suitable for temporary or semi-permanent use.
- 3mm Rigid PVC: A robust, weather-resistant choice perfect for demanding environments. This option is designed to withstand harsh outdoor conditions, including UV exposure and moisture.
Both formats feature high-resolution printing with fade-resistant inks to maintain legibility and effectiveness over time. Please note: fixings are not included with this product.
Installation Info
Installation is quick and straightforward, whether you're applying the adhesive vinyl directly to a surface or mounting the rigid PVC version using your preferred fixings. The rigid signs can be easily drilled for screws or cable ties, depending on your site requirements. Ensure the mounting area is clean, dry, and free from debris to guarantee the best adhesion or securing results.
If your site features other risk areas—such as zones requiring slippery surface signs, high voltage signs, or biohazard warnings—consider integrating this signage into a comprehensive safety system for maximum compliance.
