Warning Highly Flammable Signs | Flammable Signs
Product Summary
Protect your workforce and remain fully compliant with our Warning Highly Flammable Signs, designed specifically for hazardous environments where flammable materials are stored, handled, or used. These high-visibility hazard signs provide clear warnings to staff, contractors, and visitors, helping to reduce the risk of fire-related accidents on construction sites, in industrial facilities, and across various commercial workplaces.
Part of our comprehensive range of hazard safety signage, these flammable signs are ideal for areas where explosive vapours or materials may be present. Featuring bold black text on a yellow background with the standard ISO 7010 warning symbol, this sign ensures immediate recognition and helps you meet the requirements of BS 5499 and the Health & Safety (Safety Signs and Signals) Regulations 1996.
Whether you're updating your site safety signage or outfitting a new location, our Warning Highly Flammable Signs are an essential addition alongside other important hazard warnings such as danger signs, high voltage signs, toxic hazard signs, and biohazard warnings. Maintain a safe working environment by making potential risks clearly visible to all.
Material & Print Options
To suit a variety of indoor and outdoor applications, our Warning Highly Flammable Signs are available in two durable material options:
- Adhesive Vinyl – Ideal for smooth, clean surfaces such as walls, doors, and equipment. Easy to apply and perfect for temporary or semi-permanent use.
- 3mm Rigid PVC – A robust and weather-resistant option suitable for long-term use in challenging environments, including construction sites and industrial zones.
Both material types feature high-resolution UV-stable printing to ensure long-lasting visibility, even in harsh conditions. The sign includes the universally recognised flame symbol in accordance with ISO 7010 standards, ensuring instant awareness of fire hazards.
Installation Info
Our Warning Highly Flammable Signs are designed for hassle-free installation across a range of surfaces. Please note that fixings are not included with this product, giving you the flexibility to choose the most appropriate method for your environment—whether that’s adhesive backing, cable ties, screw mounting, or sign holders.
The adhesive vinyl option is self-adhesive and can be applied directly to clean, smooth surfaces. For the rigid PVC version, we recommend using screws, sign frames, or industrial adhesives depending on your surface type and location.
