4 Arc Flash Prevention Tips

An arc flash is nearly impossible to predict, but there are a few steps you can take to prevent one from happening at your facility.


First, why do arc flashes occur? They can happen for several reasons. The following are a few of the most common reasons an arc flash would occur:


โ€ข Build up of dust or corrosion on the insulating surfaces
โ€ข Rodents, bees, birds snapping leads at connections
โ€ข Human error
โ€ข Insulation failure

Keep reading to learn about some steps you can take to prevent an arc flash at your facility.

1. Invest in Effective Training


This is probably one of the best ways to prevent an arc flash. Make sure all of your workers that are working on energized electrical systems are qualified to do so. OSHA requires this training too. Lack of training is often cited as a reason for fines from OSHA. When you do this training make sure to document it thoroughly.

2. Perform an Arc Flash Study


An arc flash study can help to determine the incident energy level at all working locations. This will also help to determine the levels of personal protective equipment (PPE) needed

3. Wear Appropriate PPE


Wearing the proper clothing is key to protecting yourself it an arc flash would happen.
Some of the different types of PPE that you should consider wearing are listed below:
โ€ข Flame-resistant clothing
โ€ข Helmet or headgear
โ€ข Face shield
โ€ข Safety glasses
โ€ข Insulating gloves
โ€ข Shoes appropriate for electrical work (that contain no metal)

4. Mark Your Equipment


Make sure to mark your equipment to warn of hazards. This is a revision to NFPA 70 that took place in 2002. This will help your workers to be aware of where the hazards exist.

By taking these prevention steps, you can reduce the chance of an arc flash happening at your facility.

What does an electrical drawing consist of?

An accurate electrical drawing will commonly consist of several different things.  They will show the incoming lines including their voltage, size, capacity, and rating. They also show power transformers; listing their rating, winding connection and grounding means. In addition, they show incoming main switches and main and tie breakers. One of the most important things an electrical drawing may show is all of the main cable and wire runs with their associated isolating switches. Electrical drawings also show the feeder breakers and fused switches. Lastly, electrical drawings show all of the critical equipment; such as, batteries, generators, air conditioning, et cetera, and their voltage and size.

What are some electrical drawing services?

Some of the most important and common services included in an electrical drawings are as follows: short circuit calculations, coordination studies, load flow studies, safety evaluation studies, electrical safety procedures, efficient maintenance, and other engineering studies.

So, why do I need an electrical drawing?

Now you know what an electrical drawing is and what it may consist of, but you may still be wondering why you need to spend money on an accurate electrical drawing.  Electrical drawings are absolutely crucial for documenting, troubleshooting, and communicating information about your power systems on your site. They can help to ensure your system runs smoothly, efficiently, and most importantly: safely. They can even help you highlight potential risks that you can correct before a problem occurs. If all of these benefits donโ€™t convince you that you need an accurate and updated electrical drawing, maybe this will: electrical drawings that are updated and accurate keep your facility compliant with all of the code regulations.

Overall, having an electrical drawing is something you should have. There are tons of benefits to you as a company to have an updated and accurate drawing done.
