DOOR CLOSERS & CONTROLS
‘ When a door closer doesn ’ t function properly , it directly impacts the performance of the fire door it has been fitted to .’
doors where optimum clear opening widths are a key requirement such as hospital corridors .
The importance of inspecting closers
Fire doors are designed to prevent the spread of fire and smoke , creating time for people to evacuate the building . As is the case with all fire safety measures , it is essential that fire and entrance doors and the associated hardware , particularly the door closers , are kept in good working order .
Regular inspections play an important role in making sure wear and tear that may lead to defects are quickly detected and repaired .
Door closer inspection best practice
The following guidance is aimed at ensuring a robust inspection of door closers . This involves asking the following key questions :
• Is the closer fitted in the correct position ? Is it still attached correctly to the door and frame or has it become loose or dropped ?
• Has it been damaged in any way ?
• Does it allow the door to open smoothly ?
• Does it close the door in a controlled manner ?
• Are all of the screws and other fixings still tightly in place ?
• Are there any signs of fluid on the outside of the door closer or on the face of the door ?
The impact of faulty door closers on doors
When a door closer doesn ’ t function properly , it directly impacts the performance of the fire door it has been fitted to . More specifically , faulty door closers can result in doors :
• Not latching correctly when opened to 5 degrees or 75mm
• Taking too long to close – within 25 seconds is considered best practice
• Not easily opening by up to at least 70 degrees
