Every garment is designed with exceptional quality and inherent properties to provide the ultimate wearer experience.
New Lightweight Arc Flash Resistant Clothing Range

Arc Flash Standards
New garments are half the weight and more durable than existing products.
ProGARM, the UK’s leading Arc Flash resistant clothing & protection specialists, has announced an innovative new range with waterproof trousers, jackets and coveralls set for launch.
The new products are designed with the purpose of providing comfort and durability to the wearer, utilising an advanced composition technique that has been found to last longer than its previous iteration. With fire extinguishing properties, the new lightweight range also offers ultimate protection against Flame and Arc Flash Hazards.
All of the new products meet EN regulations and have been tested to 100,000 abrasion cycles – providing an ideal alternative to ProGARM’s existing range, with the key differences being that the new garments weigh half as much, have a seamless shoulder to offer more comfort when in a harness whilst crucially, still providing the same levels of protection against an Arc Flash.
Lightweight, waterproof and removable hoods mean these new products combine durability with comfort, ensuring workers can do their job with maximum protection and efficiency.

Managing Director of ProGARM, Tony Arnett said of the new products, “This new range shows just how committed ProGARM is to giving workers the best protection against Arc Flashes, whilst providing the ultimate comfort in fit.
“We are constantly innovating and trying to produce quality PPE that gives workers at risk the best possible protection as well as allowing them to do their jobs without their garments hindering movements.”
These new garments are the latest addition in ProGARM’s growing collection of PPE and will be used in many different industries that are at risk such as power generation, petrochemical, rail and utilities to prevent serious harm or death. The coverall is the lightest ever produced and features inherent VXS+ fabric, providing the same strength, tear and tensile as ProGARM’s 6458. The fabric is also highly durable, with less than 3% washing shrinkage; as well as breathable and soft to wear.

6460 ARC FLASH PROTECTION Coverall
The latest Arc Flash resistant clothing release from ProGARM is the 6460 lightweight coverall.
The 6460 premium lightweight Arc Flash coverall in VXS+ is super light with 160gms fabric. It is designed specifically for workers in the utility and energy markets requiring a lighter weight solution. The coverall features abrasion resistance up to 100,000 cycles and the same tensile & tear strength of the heavier 6458 coveralls.

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.
