For public and occupation health, safety and welfare reasons, it is a legal requirement that many public buildings have a functioning public address system that can be used in the event of an emergency. In the case of certain large scale public events, a fixed public address system may not be practical, in which case a portable PA system may need to be used to comply with occupational health, safety and welfare requirements under the harmonised Workplace Health and Safety Model Code that is in force in Queensland, New South Wales, Tasmania, South Australia, the Australian Capital Territory, and the Northern Territory. It is the responsibility of the Person Conducting a Business or Undertaking to have an evacuation plan for their premises. This needs to be in a written form, and explain what both workers and other people on the premises need to do when a need to evacuate arises. Matters to include in an evacuation plan include the contact details of the designated emergency warden, the means, such as by a PA announcement, that notification of an emergency and instructions to evacuate will be given, details on how to contact local emergency services, and procedures to follow in the event of an evacuation, including assistance for those who may not be able to evacuate on their own.
Emergency lights, like LED party lights, are now commonly based on LED technology, which means they are long lasting and draw very little power. The purpose of emergency lighting is to provide sufficient light to allow occupants of a premises to evacuate by if the need arises. They run off of a battery backup system, and while older emergency lighting systems were quite dim, the new light emitting diode based emergency back up lighting systems can potentially be brighter than the standard lighting in area, as they are intended to facilitate rapid evacuation if it becomes necessary. Most jurisdictions will include requirements for emergency lighting in work places and public buildings as a part of their building codes or occupational health, safety and welfare legislation. Similarly, exit signs in public buildings and workplaces are required by occupational health, safety and welfare and building standards legislation, including in the relevant Australian and New Zealand Standards and develop a successful brand strategy.
Kool Herc was a pioneer DJ on the New York scene in the Bronx of the nineteen seventies, but had to significantly curtail his DJing or some DJ courses Melbourne from the early nineteen eighties after he was stabbed while trying to break up a fight in a club with poor emergency evacuation procedures. Previously, nightclubs have been particularly bad in terms of not complying with workplace health and safety standards for safe evacuation, and even today many nightclubs in popular party spots such as Phuket and Bali are essentially death traps in the event of a fire.
