Hi, The extractor fan on the squash courts has a fault and has stopped working. This fan circulates the air out of the courts and, in particular, reduces the humidity of the air in the courts. As a result of this increased the humidity particularly if there are several hard matches played consecutively on cool wet evenings this means that the walls can get damp and slippery. An engineer has been contacted urgently to examine the fan and get it working again, meanwhile there is a risk that the court walls can get slippery in the late evening if the courts have been used consistently. My apologies for this problem which we are trying to sort out as quickly as possible. Regards Andrew Jennings Squash Captain.
