DESCRIPTION
AC Plant Glazing is a long-established family company providing a nationwide glazing service for quarry plant and other equipment such as cars, buses, coaches and HGVs.
Windscreen repair and replacement in quarries makes up only a small fraction of its overall business but is seen by its staff and customers as the greatest risk to safety. This is because of the working environment and the requirement to work at height when replacing most heavy plant and machinery’s windscreens.
Windscreens installed on operator’s cabs of larger equipment are often unsuitable for traditional mobile scaffolding methods. A few years ago, AG Plant Glazing developed its first Mobile Fall Prevention Device (MOFAP) to meet the safe working at height requirements of equipment used in quarries. The key objectives were to facilitate unencumbered access with potentially large pieces of glass whilst providing an overhead fall arrest anchor point for the fitter’s harness and allowing the screen removal and replacement work to be completed. The system is based on an inertia reel that does not inhibit movement but locks in the event of a fall.
Please see the entry in the 'Sharing good practice guide 2026' and watch the video to find out more about the solution.
