P50 service free extinguishers – end user video

To emphasise the advantages of the P50 service free extinguishers to end users, Safelincs created a short promotional video demonstrating the benefits and cost savings of the extinguisher.

The P50 extinguishers:

  • Do not require external service engineers. A simple annual visual inspection by the end user is sufficient
  • Do not require a refill after five years, as the firefighting chemicals are guaranteed for ten years
  • Can even be refurbished after ten years to give another ten year life

These extinguisher also help to reduce your carbon footprint, save time and even space, as the superior ratings mean that less P50 units are required to cover a building when compared to traditional extinguishers.

 

Introduction to foam fire extinguishers

When foam fire extinguishers first came into being, it was fair to say that they weren’t a massive success. Indeed, these early variants produced foam which was thick, gloopy and, because of the high animal protein content, smelled absolutely terrible. Thankfully, today’s Aqueous Film Forming Foam (AFFF) extinguishers are a distinct improvement.

AFFF extinguishers are painted red with a cream panel and are widely considered to be one of the best all-round units available. AFFF foam extinguishes and smothers flames when it is initially sprayed onto a fire. After this, it seals in combustible vapours under the film of foam and penetrates any absorbent materials, cooling the fire as the water in the foam evaporates. The spray nozzle on foam extinguishers allows a fire to be coated quickly and evenly. Furthermore, the spray of a foam fire extinguisher is non-conductive, therefore an AFFF extinguisher can be safely used near (but not directly on) live electrical equipment.

Foam is particularly effective on Class A fires (those involving paper, wood, etc) so they are a very good choice for offices or similar environments which contain a lot of fabrics. When used on flammable liquid fires (Class B), AFFF foam forms a film that prevents re-ignition of the flammable liquids by sealing the liquids off from oxygen. Class B fires also include man-made fibres which might liquefy in the heat of a fire.
