Do Not Extinguish With Water Sign | Prohibition Signs
Product Summary
Ensure safety and compliance in hazardous environments with our
Do Not Extinguish With Water Sign. Designed to warn personnel against using water to extinguish certain types of fires—such as those involving flammable liquids or electrical equipment—this clear and highly visible prohibition sign plays a crucial role in workplace fire safety. Displaying universally recognised symbols alongside bold, easy-to-read text, the sign delivers a critical safety message at a glance.
Ideal for construction sites, industrial premises, and commercial facilities, this sign helps to meet Health and Safety Executive (HSE) regulations and promotes responsible behaviour in the event of a fire. It is part of our broader range of
prohibition signs, which includes essential signage such as the
no entry sign,
no smoking sign, and
no admittance sign.
Material & Print Options
Choose the right material to suit your environment. Our
Do Not Extinguish With Water Sign is available in two high-quality formats:
- Adhesive Vinyl: Ideal for smooth indoor surfaces, this self-adhesive option is quick to apply and perfect for areas where drilling or screwing is not suitable.
- 3mm Rigid PVC: Built for durability, this rigid plastic sign is suited for both indoor and sheltered outdoor use, offering long-lasting visibility even in tough site conditions.
Both variants are printed using fade-resistant, high-contrast inks, ensuring the safety message remains clear and legible over time.
Installation Info
The sign is supplied without fixings to give you full flexibility in installation. Depending on your chosen material and location, you can mount the sign using screws, cable ties, adhesive pads, or any other suitable method. Ensure the sign is prominently displayed near fire extinguishers or equipment where water should not be used.
