this is from Facebook but a timely reminder
Just a reminder if you use an extension lead no matter how short a distance you need it, always uncoil all of the lead, otherwise it can overheat and catch fire, An extension reel is an extension lead that rolls up, usually into the socket end, which in some cases has more than one socket on it (often 2 or 4). The cable in these extension reels can be any length from 2m to 25m. If the reel contains a particularly long cable then the danger is increased. Current flowing in a cable generates heat, this causes the temperature of the conductors to rise until the heat lost balances the heat generated. If the temperature gets too high the insulation on the cable softens and eventually melts. This can cause a serious hazard when using extension reels because the cable is tightly packed together. Excess cable in a loose jumble on the ground is far less likely to overheat than excess cable wound tightly on a reel
