Arc flash analysis is the analyzing of energy explosions resulting from electrical arcs connected to a voltage phase in electric systems. The explosion has many likely origins, some of which can be deemed accidental, such as dropped tools and corrosion. Other factors include improper work practices and sabotage.
A flash explosion can be as hot as 35,000 degrees. That means it is a very deadly phenomenon. As an example of how prevalent these types of incidents are, it is estimated that in the united States of America that 5 to 10 people each day are the victims of an arc flash. Even though the risks will probably not be reduced to zero, by investigating equipment before an accident starts a firm can reduce the risk.
Laws are not enough to ensure the safety of employees. That's why states and organizations have implemented arc flash analysis policies to look into he safety of anyone working in the close vicinity of electricity and electrical equipment. One of the things that has come out of this is increased data collection. More up-to-date information on systems has been gathered so that the instances of explosions can be predicted and prevented before they start.
Initially the engineers that come into a firm will usually look at their power systems and short circuits. These investigations are crucial in uncovering whether it's OK for employees to use equipment. The work of the engineer should greatly reduce the prevalence of accidents at work.
One of the best ways to increase the risk to employees is for firms to embark on cost cutting exercises. These can compromise staff safety and leave employers liable to prosecution. As an example, NFPA tables are supposed to be a short-term solution until an engineer has done a complete inspection and has made recommendations. However, some firms will ignore reports and just use estimated levels of risk.
Some firms cannot even be bothered to bring an engineer into the firm. The thinking behind this is that it will save money and that the engineer is probably an expense not worth paying. This does not address the issues of making sure staff are in a safe environment. The best way of ensuring employee safety is to let engineers collect data and then act on the reports they have provided.
As arc flash blasts are calculated in term of time and energy, the inherent danger of forgoing analysis is obvious. If the engineer adheres to best case scenarios then workers will be exposed to high levels of risk. If anything does happen the firm could be liable. On the other hand, if the engineer calculates worst case scenarios they could end up buying too much safety equipment and wasting money.
Arc flash analysis is an important part of safety in the workplace. Engineers provide details reports to companies which should then be looked at an acted upon. They may cost money in the short term but can save money in the long run.
