M28 extinguishers are specifically designed to respond to fires involving only certain types of metals. It’s important each M28 unit is labelled as such to prevent misuse. This M28 fire extinguisher sign is constructed of sturdy, rigid plastic and coated with a photoluminescent, glow-in-the-dark coating for high visibility even in the dark. Universal BS EN3-5 graphics for consistency across signage. Meets compliance requirements of Fire Safety Order 2005. Affixes to any wall easily with standard adhesive such as sticky pads, ‘No-Nails’ or double-sided tape. Your choice of landscape or portrait orientation. Manufactured by Jalite.
