Fire doors play a vital role in protecting lives, property and buildings from the devastating effects of fire and smoke. Fire doors are not like ordinary doors, they are carefully engineered safety devices which are designed to meet specific regulations to hold back fire for a specific period of time. This helps with the containment of fire and prevents it from spreading throughout a building.
The primary purpose of a fire door is to save lives. In the event of a fire, fire doors helps to keep escape routes clear or smoke and flames and allow people to evacuate safely. By compartmentalising a building, fire doors give occupants and emergency services valuable time to respond.
Fire doors act as a critical barrier to stop fire and smoke from spreading rapidly throughout a building. Fire doors are specifically designed to hold back fire for 30, 60 or 120 minutes (depending on their rating). This helps to significantly reduce damage caused to the rest of the building.
UK Fire Safety Legislation requires that all fire doors are correctly installed and maintained. Ensuring that fire doors are compliant with legislations and regulations protects you from legal penalties, and more importantly, ensure that your premises are safe and fit for you. Cooper & Donnelly Ltd is a third-party Accredited Company under the BM TRADA with the Q-mark Fire Installation and Fire Door Maintenance Scheme.
By limiting the spread of fire, smoke and heat, fire doors help to protect your building’s structure, contents and critical assets. This containment can dramatically reduce costs and business downtime after a fire.
