Electricity & Arc Flash
what is an arc flash?
An arc flash occurs when an electrical discharge travels through the air, releasing an intense burst of energy. This can happen due to various reasons such as voltage spikes, worn connections, cable strikes, or insulation gaps. The energy released can reach temperatures up to 35,000ºF (19,000ºC), causing severe burns, injuries, and even fatalities. Proper arc flash protection is crucial to minimise these risks.
Electricity & Arc Flash
box arc test
Arc protection class APC 1 or APC 2
Fabric is exposed to an electric arc confined in a specific box with a specific electrode arrangement. This special box design releases a constrained direct exposure on the fabric (unlike the open arc test).
APC 1
- Arc Protection Class 1
- Test current of 4 kA and test voltage of 400V
APC 2
- Arc Protection Class 2
- Test current of 7 kA and test voltage of 400V

Electricity & Arc Flash
open arc test
Fabric is quantified in terms of its Arc Rating, expressed in cal/cm2, that value being either
Arc Thermal Performance Value (ATPV)
Numerical value of incident energy at which the heat transfer through the test specimens is enough to reach the Stoll criteria with 50% probability
Energy breakopen threshold (EBT)
Numerical value of incident energy at which breakopen occurs with 50% probability
Energy Limit (ELIM)
Numerical value of incident energy below which there is no data point with the amount of heat transmitted through the product reaching the Stoll criteria, or with the fabric exhibiting breakopen. Calculated by averaging the three incident energy levels below the mix zone.
The ‘mix zone” is known as the range in testing between the lowest incident energy level that crossed the Stoll Curve, and the highest incident energy level that did not cross the Stoll Curve.

Electricity & Arc Flash
ELIM testing method
ELIM (Incident Energy Limit) is a key metric for assessing arc flash protection, distinct from the Box Test and Open Arc Test methods. ELIM measures the incident energy level at which a fabric or garment passes arc flash testing, providing a conservative and reliable measure of safety.
Key points:
Accurate safety measure: ELIM is closest to a 100% pass rate, offering the most dependable protection.
Maintain risk standards: Lower ELIM ratings should not lead to reduced incident energy values in risk assessments. Always uphold stringent safety practices.
Regulatory alignment: ELIM aligns with PPE regulations, ensuring consistent and effective protection.
Specify ELIM to ensure the highest safety levels in your work environment.

frequently asked questions
Conducting an arc flash study or risk assessment is the first step. This will help identify potential hazards and determine the necessary level of protection for your team.
Under arc flash clothing, it is recommended to wear non-melting, natural fibre garments such as cotton or wool. Avoid wearing synthetic materials like polyester or nylon, as they can melt and cause additional injuries in the event of an arc flash. Specialised arc-rated base layers are also available and provide an additional layer of protection.
Arc flash protection is essential in industries such as power generation, utilities, petrochemicals, rail, and industrial electrical sectors.
Conducting an arc flash study or risk assessment is the first step. This will help identify potential hazards and determine the necessary level of protection for your team.
Arc flash garments should conform to EN 61482-2:2020, EN ISO 11612 :2015 , and other relevant standards to ensure comprehensive protection against thermal hazards.
Arc flash clothing is specifically designed to protect against the intense heat and energy of an arc flash incident, while flame retardant (FR) clothing provides protection against flames and thermal hazards. Understanding the distinctions can help ensure your team has the appropriate level of protection for their specific work environment.
Conducting an arc flash risk assessment involves evaluating the potential for arc flash incidents in your workplace, identifying areas of high risk, and determining the necessary protective measures. It typically includes an analysis of electrical systems, equipment, and working practices.
Key standards for arc flash protective clothing include EN 61482-2:2020, which specifies requirements for materials and garments to protect against thermal hazards, and EN ISO 11612, which outlines general protective clothing requirements against heat and flame. Compliance with these standards ensures garments provide adequate protection.
The lifespan of arc flash protective garments can vary based on usage, laundering, and wear and tear. Regular inspections and adherence to manufacturer guidelines are crucial to determining when garments need replacement. Generally, if any damage or significant wear is detected, the garment should be replaced immediately.
Layering arc flash protective garments can enhance overall protection by increasing the level of insulation against heat and energy. Each layer adds a barrier, reducing the impact of an arc flash incident. Proper layering also helps in achieving the required Arc Thermal Performance Value (ATPV).
Yes, arc flash protective clothing can be customised to meet the specific needs of different job roles or environments. Customisation options include additional features like high-visibility strips, extra pockets, or specific garment designs that cater to the unique requirements of various industries and working conditions.
