Dealing with contamination from bodily fluids can cause much debate, though in practice a simple and cheap spill kit - such as for blood contamination from grazes and minor cuts - can prove adequate. Newer synthetic carpets are much advanced from earlier types: modern fibres are typically made from polyethylene which provides a much softer surface and is less demanding on players' legs when compared with earlier carpets, although the heat impact of reflected solar radiation can increase fatigue significantly. Heated debate With the Women's World Cup in Canada having taken place on 3G pitches, some interesting issues have already arisen from the competition, the most prominent being the effects of heat from very high temperatures generated by the response of the synthetic material to solar radiation. The problems of elevated surface temperatures were reported back in 2007 in the Journal of Turfgrass and Sports Surface Science (Vol 83), with surface temperature differences between a green artificial surface and natural turf grass surface (which provided a much cooler and consistent temperature and which the IOG considers provides the best all-round playing experience) varying from 15C to 40C. While this research was conducted in Las Vegas, "even cities with cooler air temperatures might need to address the potential risks associated with elevated surface temperatures of artificial grass". Maintenance plan When planning maintenance, it is important to consider the standard of performance which is to be continually achieved from the playing surface, the amount and type of weekly usage, as well as the type of carpet used. As a general guide, 10 hours' of usage will require one hour of routine maintenance. However, the actual weekly maintenance input for a synthetic pitch might typically range between four and 17 hours. ('Synthetic Turf Study in Europe, 2012', KPMG). Keeping documented records of what takes place on a pitch it confirms what has been done, allows for budget planning and control, complies with funding requirements (where applicable) and can assist in mitigating compensation claims, especially spurious ones. The correct maintenance and deployment of non-socketed goalposts is an area that is relatively easy to comply with. However, complacency can creep in and "several serious injuries and sadly even fatalities have occurred in recent years as a result of unsafe or incorrect use of goalposts" (The FA Guide to 3G football turf pitch design principles and layouts', 2013). If you are interested in learning how to effectively maintain 3G pitches, the IOG and its partners are delivering a number of courses during July and August.

Chris Gray is head of education at the IOG. l Partners in 3G excellence Over a decade ago Redexim Charterhouse teamed up with industry experts to develop a range of artificial surface maintenance equipment and today there are Redexim models to suit all applications – from a light surface brush to a full deep clean, with product certification by the Synthetic Turf Council. For example, the Verti- Clean will pick up surface debris with a rotating brush, powered by ground wheels, and throw it onto a vibrating sieve. The sieve filters the infill material back onto the playing surface while retaining the debris in a lightweight hopper that can easily be removed for emptying. A PTO-driven version makes for easier removal of larger amounts of dirt, debris and detritus as the rotary speed of the brush can be varied. Replay Maintenance is at the forefront of every type of synthetic turf maintenance, employing a range of specialist machines, processes and techniques to improve porosity, enhance playing performance and recover player comfort. The Replay Revive procedure removes contaminants and reduces compaction. First, all large debris that has been left to decompose on the surface, to inhibit drainage, is removed. A self-propelled rotary brush unit then penetrates the surface to a defined depth to lift and filter the infill. The integral turbine vacuum extracts the fine contaminates before a rear-mounted, hydraulically- controlled brush passes over the surface to redistribute the infill.
