Roof Over-Netting Committee
With the involvement of the HSE, this committee was developed to evaluate the effectiveness and suitability of Roof Over-Netting (RON).
Roof Over-Netting is becoming more commonplace due to the need of replacing fragile roofs on industrial and agricultural buildings where it is not always possible to install safety netting under the roof structure. As a last resort, some installers have been forced to lay nets over the top of the roof, thus supplying a level of protection for roofers should they step or fall into the roof during their works.
The committee first discussed the methods employed by those FASET Members involved in this specialist work, with an aim of developing guidance for its safe use. It quickly became apparent that testing was required to evaluate the effectiveness of this method of netting, so a test rig was built with fragile roof sheets secured to perlins and over-netted.
A test mass was dropped into the test rig, with a variety of roof fixings, perlins and nets being used. This testing led to the need for another days testing, using a rig of a larger size with smaller bay centres to evaluate whether the net performed differently. The committee has recently met to agree in what format guidance should be produced and work is ongoing to develop this into something the industry can refer to.
Training for both operatives, supervisors and managers is now being developed which will cover safe working practices, installation methods and safety considerations. This training will be re-enforced with a syllabus of information to be delivered by the supervisor at each job.
