Extinguishing system for protecting the delivery area and the material storage

Located in Colnbrook near Heathrow International Airport, Grundon operates a large materials recovery facility (MRF) that processes and prepares paper, cardboard, metal and plastics such as polyethylene (PET) and polypropylene (PP). The materials are highly flammable and often highly self-igniting. To minimise the risk of fire, Rosenbauer developed a complete stationary solution for the MRF.

Impresses with

  • Highly effective fire fighting technology
  • Water supply: 28,000 l
  • Turret extinguishing system and temperature monitoring
  • Hotspot detection and targeted extinguishing agent use
"After intensive research and evaluating various solutions, I came across the Rosenbauer system and set out to work with them to develop a system for our plant in Colnbrook. The system is designed to handle fires at a very early stage. Foam can reduce the spread of fire. Throw ranges of up to 60 m with targeted extinguishing agent application ensures that the combustible material is safely reached over the entire length of our hall. The Rosenbauer technicians were competent and the entire installation went smoothly thanks to the professionalism and expertise of the Rosenbauer team."

"My roll in the department is primarily maintenance. I am also the fire safety officer for the department. It is extremely reassuring to know that if a fire breaks out in one of the two zones, it will be detected quickly and countermeasures are implemented automatically – 24 hours a day. The local fire department visits regularly to make sure they are familiar with our facility. The fire department is very impressed by the Rosenbauer extinguishing system and is confident it will reduce the negative impacts on life, the environment and costs in case of fire."

Initial situation

The materials are highly flammable and often highly self-igniting. The delivery hall in which the materials and the storage containers that receive the waste after sorting are handled and processed are particularly at risk. A fire would destroy the expensive plant, cause prolonged downtime and endanger humans and the environment. In order to ensure the protection of sensitive areas and materials from fire, Rosenbauer uses early detection via infrared and fast cooling with foam.

Due to a nationwide water shortage in industrial zones, supplying water to the extinguishing system was an additional challenge. Rosenbauer solved the problem by using two adapted containers that hold up to 28,000 litres of water. Since both containers can be stacked on top of each other, the scarce space on the company premises is used more efficiently.

Extinguishing system

At the heart of the Rosenbauer extinguishing system is the combination of infrared temperature monitoring and an RM15 turret extinguishing system with foam proportioning. If predefined temperature limits are exceeded, the system is activated and the detected hotspot is cooled with foam for up to two minutes at a time. This prevents fires from breaking out. In addition, cameras continuously monitor the sorting bunkers into which the hand-sorted recycling material is dropped from above, the delivery area and parts of the processing area.

The storage containers are also equipped with spray nozzles, which are triggered by flame detectors. When activated, the water-foam mixture is evenly distributed in the containers and the burning material thereby cut off from oxygen. The flames are smothered and the materials are cooled sustainably. The stationary fire protection system from Rosenbauer also helps to fulfil the rules of the "Fire Prevention Plan" from the responsible environmental agency, which mandates regular temperature monitoring for such operations in the recycling industry.
