Hydro Spray Fire Extinguisher ID Sign Features and benefits: Durable and weather-resistant Rounded corners for safety Extinguisher ID information. Available in self-adhesive vinyl or 1mm rigid plastic Manufactured in the UK Our Hydro Spray Fire Extinguisher ID Sign clearly displays what a Hydro Spray fire extinguisher should and should not be used for. It is designed to be situated on or beside the corresponding fire extinguisher so that everyone is informed on how best to extinguish a fire before it becomes too dangerous. Hydro-spray is a brand name and a type of water extinguisher. Water extinguishers have an extreme cooling effect, lowering the temperature of flames and making it impossible for the fire to burn while smothering them with their high pressure. Hydro-spray extinguishers are useful against Class A fires such as wood, paper and fabric and must never be used on electrical, flammable liquid or flammable metal fires. This sign uses bright red and green colours as well as iconographic symbols of a fire extinguisher to allow people to quickly discern what it should or should not be used for.
