We completed an upgrade project at the Bristol Royal Infirmary, which included the installation of a new Deck Integrated FireFighting System (DIFFS) on the hospital's helipad. We also modernised the manual firefighting system as part of the upgrade. The new DIFFS system is fully automated, with just a single push of a button, the system is activated in the event of a fire on the helipad. This upgrade has significantly enhanced the safety and security of the hospital's operations, while also minimizing the risk of potential fire hazards.
