Are You Fixing Fire Collar Right?

Tuesday, May 14, 2013

On many occasions throughout my career, the simplest of faults found is when a fire collar is not fixed according the manufacturers data sheet installations. I mainly refer to retro-fit fire collars found to the underside of a concrete slab or a side of a wall. Contractors have incorrectly installed nylon pins, green plugs and screws, liquid nails and in some cases nothing at all. When, in fact, they should be using the correct steel expanding fasteners to concrete or the correct sized chipboard screws to plasterboard walls/ceilings.
