The Arc Flash Hazard Analysis

By Iva Cannon


You may have heard about an arc flash from your colleagues or friends and not well understood what it this concept is all about. An arch flash is an occurrence which is as a result of a rapid release of energy from an arcing fault line between two phase bus bars. This can be a neutral or a ground. During the fault, the air acts as a conductor. The arc faults generally occur on bus voltages with more than 120 volts. An arc flash hazard analysis is necessary for an industry to ensure that workers safety is ensured.

The massive energy released by the fault burns the bus bars and vaporizes the copper and thus causing an explosive increase. This explosion is very devastating and it destroys everything on its path. This effect is very deadly and can cause great harm to individuals or workers around the area of damage.

There is a regulatory body which sets up regulations that ought to be followed to ensure safety for workers against these flashes. The industries are required to conduct a hazard assessment test to ensure that the electrical systems within the industry are properly functioning. The tests help prevent risks that could be posed to your personnel.

The analysis is led by an individual or group of qualified specialists. The specialists survey the framework and after that create a definite report identifying with the arch flash state in the business. The report will have proposals and guidelines on the best way to keep your representatives safe, enhance your framework, overhaul or how to maintain electrical framework. This report will suggest the proper defensive hardware for the laborers. It will likewise recommend the changes important to lessen the workforce exposure to these hazards.

There are various experts, technicians or analysts who can offer you such a service. They either work as own self employed individuals or under some company name. Those that are employed by professional firms would be more recommended for hiring. This is because most of them are highly qualified academically, experienced and certified by the regulatory bodies. When considering consulting a self employed expert, keenly look at the testimonials from former clients who were served by him or her.

The regulatory framework that imposes these guidelines requires that firms carry out several protective measures. These include; demonstrate their safety programs, provide personal protective equipment to workers, offer tools or safe working and give warning labels on equipment. They should also offer training for workers on the hazards of this occurrence.

The process of analysis is carried out by first collecting the necessary data about the power distribution system of the facility. The details on lengths of all cables are also taken. The facility should provide the maximum and minimum current voltages expected to enter in it. This data is then fed in to equations provided in the required standards. These equations then generate the required flash protection boundaries.

When looking to hire a firm to carry out the assessment for you, you should be cautious. Search for a firm which has experience, necessary tools and employs qualified staff. You can consult other industries for references to the best analyst they have dealt with.
