When organizing any kind of event such as a conference, convention, trade show, or other similar gathering, one should always ensure electrical safety. This is particularly true when you will be using any number of electrical equipment at the same time during the conference or event. Whether it is radios, televisions, sound systems, projectors, computers and laptops, phones, and various lighting and heating solutions, you are expected to be right on top of such electronic logistics, and to deliver as seamlessly and as efficiently as possible. This can only be done, however, with the assistance of a professional and licensed electrical contractor. It is not something that one can simply experiment and play around with, no matter how good you may be at basic electrical systems maintenance. The work required for checking, maintaining, and delivering emergency repairs to the electrical installations of a commercial building requires the kind of expertise that only comes from extensive education and experience.
All things considered, however, there are a few basic principles which you can double check yourself to make sure that electrical installations and systems will not be a cause of concern for public safety. This is important because unsafe or dangerous wiring or electrical work can lead to serious injury or death.
Some general measures by which you can ensure electrical safety during a public event include:
- The location of an organization of power lines or cables
- Environmental conditions such as rain, and the possible exposure of wires to the rain
- The layout of electrical systems and wiring, making sure all the while that public access routes are kept free and safe for the passage of people
- Power requirements, given the equipment that are proposed to be used, and access to primary and secondary power sources in case of an emergency
- The power supplies for non-permanent fixtures or equipment like cameras, lights, and makeshift booths, etc.
- Clear communication lines between event organizers and yourself, which may involve battery-operated radios or speakers.
Protecting exposed cables is of particular importance during public events. First of all, such cables should meet electrical safety standards such that adverse environmental or weather conditions will not adversely affect the electrical systems and installations.
Should such cables be routed across open areas, it is also important to prevent potential mechanical damage that might come from heavy equipment being dragged across such cables. One would also need to prevent incidents of tripping over such cables. In most cases, the most feasible solution is running cables along routes that are not heavily trafficked such as the sides of walls or fences, and providing cable routes where necessary, and securing these with cable ramps. Should you choose to make use of cable bridges that consist of hoisted installations over which cables can be run, then it should be of sufficient height, generally not less than 5.8 meters if installed across a road, to ensure that most vehicles will be able to pass safely underneath it. Such cable bridges should also be equipped with sufficient warnings or notices to make sure that the public is aware of the potential danger, and knows to practice safety in where they walk or pass through.
