The editorial of my teaching society's bi-monthly magazine was concerned, recently, with Health & Safety on the dance floor, and among the issues mentioned were that the floor should not be slippery and that the area should be sufficiently warm. I was teaching in a studio at the weekend, it's an old building with an inadequate heating system, and it had been a cold night (early Winter here in UK). It was 0c outside, but only 11c inside. That was too cold for comfort. What do others think is the minimum temperature that is acceptable? Another recent discussion mentioned wax on the dancefloor, and I also wonder what others think about it's use. Parafin wax can easily sit on the surface of a wooden floor, and while a flat foot will find the floor has lovely feel, and is very stable, the edge of a heel can create a pressure point where the foot can all too easily shoot out from under the dancer, resulting in a nasty fall, or strain. When that happens, it is usually attributable to poor placement of the foot in relation the body's weight, but inexperienced dancers do not have enough control or understanding of the dynamics of the body in motion to place their feet perfectly every time. Does the hazard outweigh the benefit? And if the instructor recognises that is is a hazard, does he have a duty of care to change the floor preparation regime, or, if that is not under his control, to change studio? The issue of temperature is directly related, because at higher ambient temperatures, wax softens and soaks into a wooden floor differently from the way it behaves on a cold one.
