5 Arc Flash Risks for Solar Industry Personnel
January 15th, 2020
Arc Flash Risks And Dangers
Introduction to Arc Flash
The proliferation of solar panels used in industrial and commercial building is a reflection of the decreasing cost of the photovoltaic modules and the increasing interest in renewable energy sources. The widespread use of photovoltaic systems increases the risk of exposure to electrical safety hazards that are inherently associated to nonlinear power sources.
It is a well-known fact that the standard protection devices are inefficient in detecting short circuit faults in photovoltaic systems. In addition, it is now recognized that the maximum incident energy deployed by a DC arc flash in a photovoltaic system is higher, and in many instances significantly higher, than those estimated by using the guidelines given by the NFPA 70E and the CSA Z462-12 standards.
Use of the existing guidelines can result in personnel being exposed to much higher safety risks than previously thought – here we consider 5 Arc Flash risks prevalent in the solar industry.

Arc Flash In the solar Industry
With government plans to significantly increase the amount of energy generated through sustainable sources well underway, and with solar panels recognised as one of the most accessible ways for homeowners to make the switch, the solar industry is booming.
However, this is also an industry that comes with notable risks, particularly in terms of arc flash hazards.
The risk is so pronounced within the solar industry in particular due to the DC circuits found within typical PV installations, which can both generate and sustain arcs.
DC circuits present a greater challenge than AC circuits due to the constant-current source rather than constant voltage, which makes calculating arc energies difficult.
So just what are some of the biggest Arc Flash risks for Solar Industry Personnel?
The design systems of PV installations pose one of the greatest risks as there are many types of intermittent connection that the system can create which may then generate series Arc.
For example, anything from compression wire connections to soldered joints to the actual connectors that attach to the PV modules are all capable of creating intermittent connections and generating series arc. Quite simply, Arc Flash can occur remarkably easily within the solar industry, resulting in greater risk for solar personnel.

News: The largest solar power plant ever proposed in the UK will be reviewed by the Secretary of State within the next six months. Cleve Hill solar farm will occupy the north coast of Kent and, if built, provide up to 350MW (megawatts) of generating capacity.
Arc Flash Heat
The types of Arc Flash that can be generated within the solar industry are another major risk. With arcs capable of reaching more than 3000 degrees Celsius in temperature, these arcs not only cause fires but can also melt materials such as glass and metals including copper and aluminium. This can subsequently ignite any combustible materials and items in the surrounding area. In the solar industry, it is not only the direct risks of arc flash that must be considered but also the many possible indirect risks, too.
An Arc Flash event can expel large amounts of deadly energy. The arc causes an ionization of the air, and arc flash temperatures can reach as high as 35,000 degrees Fahrenheit. This is hotter than the surface of the sun.
Injury and Fatality of Arc Flash
Arc Flash Risks
With the possibility of fire (in recent years there have been notable instances in the UK, USA, and Australia of PC installations causing fires along with significant damage to both domestic and commercial properties) and molten metal, injury and even fatality is a major risk for solar industry personnel. The best way to mitigate this risk is by wearing the correct Arc Protective Clothing equipment for the environment and identified hazards.
Dedicated arc flash PPE can minimise injury when worn correctly.
System Maintenance
Maintenance of equipment is undoubtedly one of the most effective ways to quickly identify system faults and reduce the chance of arc flash. However, due to the nature of PV installations, adequate system maintenance can be tricky, and a lack of thorough upkeep poses one of the greatest risks to solar industry personnel. With combiner boxes generally being located at a distance from each other, proper maintenance can involve disconnecting entire sections of the system at a time.
Required Action
Perhaps the greatest risk of all is the risk that solar personnel take inappropriate action when arc flash is determined to be most likely. With DC circuits, there are different Types of Arc Flash that can occur, with each requiring different action to be taken. With series arc, for example, a shutdown of power and significant reduction in circuit flow is needed. With parallel arc, however, conductors must be shorted simultaneously resulting in zero array voltage. Understanding system management is the key to safety.
If you are working on live Solar Panels there is a possibility an Arc Flash could happen.
Make sure you and your team are working safely on live electricity with Arc Flash and Flame Resistant Clothing, see our full collection here.
Solar Fires – DC Arc Faults. Arc flash is a dangerous risk among those in the power industry. Arc flash is an electrical breakdown of the resistance of air that results in an electric arc, which can occur where there is sufficient voltage in an electrical system and a path to ground or lower voltage.

WHAT IS AN ARC FLASH?
Put simply: An arc flash is the light and heat produced from an electrical arc supplied with sufficient energy to cause significant damage, fire or injury.
An electric arc occurs whenever a circuit breaker, switch or isolator (Device) is opened and when there is current flowing in the circuit. However, most devices under normal operating conditions are designed to control the arc when opening or closing.
An arc flash may occur when the arc is uncontrolled and there is sufficient energy released to cause harm or damage.
Arc flashes occur both at high voltage and low voltage. There is little discrimination: low voltage arc flashes injuries are just as damaging as high voltage injuries.
An Arc Flash can cause minor injuries, third-degree burns and potential death as well as other injuries including blindness, hearing loss, nerve damage and cardiac arrest. Fatal burns can occur when the victim is several feet from the arc. Serious burns are common at a distance of 10 feet – arc flash can generate heat 4 times greater than the surface of the sun.

Arc Flash | Risk Reduction by Using Arc Flash Gloves
October 22nd, 2019
TraffiGlove – Arc Flash Gloves Specialists
The following article has been produced by TraffiGlove – Arc Flash Gloves Specialists. Special thanks for the permission to re-publish your article.
UNDERSTANDING ARC FLASH
The most common cause of all electrical injuries is arc flash – an incident which can change an employee’s life in the blink of an eye.
An arc flash is an electrical current that jumps from the intended path and travels through the air from one conductor to another. When an arc fault occurs, it causes the release of massive amounts of energy into the air, resulting in explosions which can reach up to 35,000 degrees Fahrenheit in an instant.
Such high temperatures can also vaporise metals, such as copper, which sustains the arc and amplifies its power.
WHAT ARE THE DANGERS?
Arc flashes only last for several milliseconds, but this is more than enough time for the superheated air and vapourised solids to cause significant injury to nearby workers. The intense light from an arc flash can also cause damage to the retina.
Not only this, but arc flashes are accompanied by a pressure wave and sound blast loud enough to damage hearing or even brain function. This so-called ‘arc blast’ also sends any loose debris, tools or equipment flying out from the fault at supersonic speeds causing further injuries.
WHAT ARE THE CONSEQUENCES?
An arc flash is a potentially fatal incident for any personnel in the vicinity.
Workers can suffer:
- First, second and/or third-degree burns, not only on the front but also the back
- Internal damage to vital organs from high amounts of voltage travelling through the body
- Blunt force trauma from the blast
- Shrapnel damage to the skin
- Damage to their sight
- Health effects from breathing toxic fumes
- Hearing loss
The consequences of arc flash incidents are often life-changing for the individuals involved, with treatment for burns, in particular, involving years of skin grafts and surgery.
REDUCING THE RISKS WITH ARC FLASH GLOVES
When an arc flash occurs, hands are usually the first body part to catch fire due to their close proximity to the fault. As such, workers should not wear gloves which may easily burn, ignite or do not provide any protection from heat.
Rubber insulating gloves have long since been the norm for tasks that carry an arc flash risk.
However, rubber gloves can be incredibly bulky and limit dexterity, making them difficult to work in. Due to this, many non-rubber, lightweight arc flash gloves are now entering the market.
Such gloves are made from material which is innately flame-resistant (leather, aramid, coated nylon, and glass) or treated.
These types of arc flash gloves are far more comfortable than their rubber counterparts and often provide more protection. These seamless knit solutions can also increase the level of cut protection of the EN 388 standard. However, you should always discuss your requirements with a safety specialist to ensure you wear the correct safety glove for the job.
TraffiGlove September best seller
September’s best-seller was announced as TraffiGlove’s TG5140. The glove is a close-fitting and flexible Cut C glove with a high tech MicroDex Nitrile Foam coating that provides excellent grip in wet, dry and oily conditions. The durability and glove life is also excellent.

Overhead Lines | Preventable & Fatal Risks of Electrocution & Arc Flash Incidents
October 8th, 2019Thank you to the Electrical Safety Authority for allowing us to republish this article.
Four Ontarians Critically Injured or Killed by Electricity in the Past 24 Hours
Mississauga, on (September 20, 2019) – In the last day, three confirmed electrical-related incidents that have involved four individuals have been reported on worksites across Ontario: two reported fatalities and two critical injuries. All of these incidents involved contact with overhead electrical wires.
The Electrical Safety Authority is supporting the Ministry of Labour while each of these incidents are investigated. “In the last 24 hours, four families have been tragically impacted by the dangers of electricity and we are incredibly saddened by this news,” says Dr Joel Moody, Chief Public Safety Officer with the Electrical Safety Authority. “Unfortunately, these incidents were preventable and it’s clear that more needs to be done to help Ontarians stay safe when working around electricity.”
In the last 10 years, 19 Ontarians have died after making contact with energised powerlines.
The events of the past 24 hours further reinforce the serious nature of electricity and need to always be vigilant when working close to or around energised wires.
Electrical Safety
To keep safe, ESA urges everyone to remember these safety tips when working around electricity – at home or on the job:
- Look up, look out and identify all powerlines around you. Make sure people and equipment stay at least three metres away to prevent an incident. Electricity can jump to you or your equipment if you’re too close to a powerline.
- Stay alert! Many incidents happen at the end of the day when people are tired or rushing to finish a job.
- Be aware. Drivers of dump trucks and other high reach vehicles must get a signaller to ensure that equipment doesn’t come within three metres of overhead powerlines.
- Hidden dangers. Overhead powerlines can be hidden by foliage. Tree trimming tools that contact a powerline can result in electrocution. Look closely to identify overhead powerlines running through trees and ensure that you and your tools are at least three metres away from powerlines at all times.
- Keep equipment away. Aluminium ladders, or ladders with aluminium parts, will act as conductors of electricity if they contact overhead powerlines. Even wooden ladders can contain metal and lead to a shock if contact occurs with a powerline.
- Don’t touch. If wires fall down on the truck or the ground, always assume they are still energised. Stay in the vehicle, call 911 and keep everyone back. Only the local utility worker on-site can confirm when the power is off and tell you when it’s safe to exit the vehicle.
About the Electrical Safety Authority
The Electrical Safety Authority’s (ESA’s) role is to enhance public electrical safety in Ontario.
As an administrative authority acting on behalf of the Government of Ontario, ESA is responsible for administering specific regulations related to the Ontario Electrical Safety Code, the licensing of Electrical Contractors and Master Electricians, electricity distribution system safety, and electrical product safety.
ESA works extensively with stakeholders throughout the province on education, training and promotion to foster electrical safety across the province. More information on the Electrical Safety Authority can be found at esasafe.com and on Facebook at www.facebook.com/ElectricalSafetyAuthority.
