There are many electrical hazards in industrial plants including arc blasts, shock and arc flash. These can result in serious injuries. Accidents involving electricity may sometimes be fatal. Industrial plant environments create potential for these events to occur not only to plant owners, but also to maintenance staff.

Electricians often assume that these hazards do not apply to them. These beliefs often persist until a major incident occurs that results in both financial and personal repercussions, that result in a change in policy within the plant.

Implementing policies that encourage a culture of electrical safety doesn’t have to be reactive. Taking steps to minimize the risks associated with electrical hazards will create a safe working environment for everyone, and not just the maintenance team.

One of the most important aspects of enhancing safety is establishing a routine for the maintenance of electrical equipment in the facility. This is not only vital for optimizing the performance of the equipment, but also ensuring reliability, safety and preventing unnecessary downtime.

A bit of mathematics at the end of the week. The

The first table shows three different installations. The old one is equipped with T8 fluorescent lamps that are at the end of their lifetime and dirty. That is why the luminous flux is so low for the 60W tube. In this situation, the need for a replacement is present. The choice is between a fluorescent tube, a LED tube or a completely new installation with controls. Controls reduce the average power consumption to 1/3 and less of the original load. We can estimate the new fixtures will consume 12W only when connected to controls that detect presence in the hall and reduce the lighting level in areas that are not in use. Each light point will be replaced. It is (often) possible to reduce the number of fixtures with a new installation. The example is concentrating on a one-by-one replacement to make it easier to understand.

The table above shows the sum of all costs for running and maintaining the installation each year and in total. The Retrofit Solution reaches an ROI after 2 years already. The New Installation with controls is going to turn back the high investment after 10 years. Both LED solutions do better than the conventional one, save energy and CO2 emissions. Let’s go green with LED light sources!

Across the U.S. approximately 4,400 people are injured and an additional 400 die each year resulting from electrical hazards annually. Add in electrical fire, and you have what results in an estimated $1.6 billion in property damage each year. Could these accidents have been prevented? When it comes to electrical safety, what you don’t know can hurt you.

GFCI stands for ground fault circuit interrupter. A GFCI is required in any areas with an increased risk of shock due to electrical hazards, such as water. In order to protect you from electrical hazards, a GFCI monitors electrical current, turning off an electrical circuit when it detects an imbalance - current flowing along an unintended path. Think of a GFCI as a small, extra-sensitive circuit breaker built right into an outlet to protect you against electrocution – even in outlets that are not grounded. GFCIs are currently required for use in:

Note: Never use GFCI outlets with refrigerators, freezers, or other appliances, as they could trip without your knowledge.

AFCIs stand for arc-fault circuit interrupters, and they protect you from electrical dangers, but of a different variety – those that create heat via arcing. Examples include a rodent chewing on a wire, driving a nail through a wire, or a device overheating where it is plugged into the wall. AFCIs detect this arcing, shutting down outlets before damage can occur. They are not found in wall receptacles like GFCIs, but instead are easily incorporated into your home or business’ main service panel in the form of specialized circuit breakers. AFCIs are required in:

Though you may have an older home or business where building codes do not require these outlets, proper home safety does. Regular outlets and circuit breakers are designed to protect the house's electrical system, not people. With these devices being so easy and inexpensive to install, why wouldn’t you want to protect yourself and others from the unnecessary electrical hazards overlooking them presents?

As of 2014, the National Electric Code (NEC), the nation’s singular code for safe electrical installation, has added the following standards for the safety of your home or business:

All 125-volt, single-phase, 15- and 20-ampere receptacles installed in a laundry room now require GFCI protection, whether or not a sink is present.

As dishwashers age, the risk of electrical shock increases, thus the latest requirement for GFCI protection on all dishwashers, whether they use a receptacle outlet or are hardwired in.

As of 2014, the NEC has recently added kitchen and laundry areas to the list of areas requiring AFCI protection. This includes all 120-volt, single-phase, 15- and 20-ampere branch circuits supplying not just outlets but also devices found in these rooms.
