In England the PAT is an integral part of the requirements of the Health and Safety Act of 1974. The 1974 Act states that if you are self employed (even if entertaining is not your main line of work) you are obliged to look after your own safety and that of anyone else who might be affected by your actions as far as is reasonably practical. As the employer it is your responsibility to make sure the mobile sound hire equipment is safe to use. The Executive of Health & Safety has stated the fact that one quart of all electrical accidents involves the usage of portable electrical appliances. The Mobil DJ system falls under the categorizations of "Where the electronic appliances being are supplied of hired out" and ” Where the general public may use the appliances in a school, bar, hotel establishment ect.".
The PAT will become more wide spread across other developing world countries as time goes past. Here in the Philippines Health and Safety are mystery words there is no wonder why there is so many Manila and Bangkok dangerous club and hotel fires in south east Asia music entertainment rooms.
Here the electrical fixtures and fittings are of very poor quality compared to the power connectors from Europe, there is no earth wire on the electrical apparatus circuit just two pins live and neutral. Another major problem is the plugs amperage being so low and not being able handle a vast amount of power passing through it. When I will do any upgrading of my music hire system I will not perchance the wires and sockets here but will have them shipped across here from the UK.
My last point on Disco equipment safety connectors start to convert all your plugs to 16 amp or 32 amp blue plug and sockets the type that you find in factory placers not the standard household remember stage lighting equipment safety first. The wiring use armored screen cable I know it cost an arm and a leg but in the long run much better and looks really professional also cutting down on the sound humming.
