Category 4 Gloves By ProGARM 

ProGARM Arc Flash Gloves provides Category 4 protection against arc flash with 50cal/cmaccording to IEC 61482-1-1:2009 ‘open arc’ test method.

Arc flash gloves sizes range from L-2XL and the form-fit, ergonomic design promotes superior dexterity and comfort – typically used to protect Substation SAP’s & Fitters, Commissioning Engineers, Cable Jointers, Overhead Linesmen and Utility Workers. The gloves provide arc flash protection to Category 4 50cal according to the open arc method.

The gloves are typically used in conjunction with “head-to-toe” arc flash clothing including arc flash helmets.

High-performance Kevlar lined arc flash gloves with 100% waterproof and windproof lining to keep hands warm and dry. Insulation made with Flame Resistant Nomex – for general protection against electrocution and shock insulating gloves are recommended depending on the working voltage levels.

Should you require guidance on selection and use of an Arc Flash Calculator please call Thorne & Derrick, the UK’s leading specialist distributor of electrical safety equipment for LV (Low Voltage), MV (Medium Voltage) and HV (High Voltage).

Glove | Care Information

ProGARM 2678 arc flash gloves must be carefully cleaned to ensure arc flash protection levels are maintained.

  • Do not bleach, boil or use soap based products – clean polo shirts using detergents only
  • Dirty clothing may lead to reduction in arc flash protection
  • Company will not accept liability for garments where care labels have been ignored, neglected, defaced or removed
  • Always store arc flash clothing in clean dry conditions
  • Do not store in places subject to direct strong sunlight

Safety Information

1. Prevent ignition by wearing arc flash gloves that will not ignite.
Arc flash injuries can occur anywhere on the body however hands are normally first to catch fire. Therefore you don’t want to wear arc flash gloves that will burn, catch fire, or not protect from heat. As well as injuries ignoring the need for proper electrical PPE can result in huge fines.

2. Wear arc flash gloves with sufficient protection.
Protection must be adequate for the specific threat (level of exposure) presented by the electrical equipment that you are working with. The arc rating of the machinery that the worker is using  should be written on the electrical panel. If it isn’t, it is imperative to check the manufacturer’s specifications. To choose the best arc glove for a job, you need to understand Hazard Risk Category (HRC) and Arc Thermal Protective Value (ATPV).

  • Hazard Risk Category (HRC) – safety standard showing the miniumum amount of PPE protection a worker needs in relation to the threat level of potential exposure. HRC categories range from 0 to 4, with 4 being the highest risk.
  • Arc Thermal Protective Value (ATPV) – is the incident energy level (measured in cal./cm2) that would cause a second-degree burn

The HRC and ATPV are determined through a flash hazard analysis that studies all the electrical circuits in the device capable of being energized and determines how much energy would be released in case of an arc flash. Once the risk of potential exposure is analysed the ATPV can be determined. The ATPV then guides you to the appropriate HRC level.

ASTM F1506 is the standard that determines the HRC of an arc flash glove whilst ASTM P S58 is the standard that determines ATPV. Choosing the right level of protection for the job ensures the arc flash gloves are comfortable and offer the highest level of protection possible.

Related Arc Flash Clothing Protection & Products


Arc flash clothing and garments in a layered combination deliver workwear protection against hazards according to IEC 61482 – PPE protects the worker against electric arc flash dangers. According to IEC 61482-1-1:2009 (encompassing NFPA 70E 2015) the 4 arc risk categories are numbered according to the severity threat and determine the clothing protection level required to protect against a minimum level of incident energy measured in calories / cm² – this is the ‘Open Arc’ test method and measures clothing protection level according to the Arc Thermal Performance Value (ATPV).

NFPA 70E Arc Flash Clothing

NFPA 70E outlines the requirements for safe work practices to protect personnel by reducing exposure to workplace electrical hazards.

The ‘Box Arc’ tests clothing materials and fabric according to a pass/fail test by exposure to electric arc produced by 4kA (Class 1) and 7kA (Class 2) short circuits – this is IEC 61482-1-2:2007.

Electrical Insulating & Arc Flash Protection Gloves

There is often misunderstanding about hand protection requirements and the type of glove required to provide protection against electrical shock (electrocution) or arc flash hazards. Electrical safety rubber insulating gloves provide voltage protection and arc-rated or flame-resistant gloves provide heat protection – it is critical to understand that voltage protection is provided by correctly tested rubber insulating gloves only. Arc-rated or flame resistant gloves DO NOT provide dielectric protection. Performing voltage testing or other energized and potentially energized work tasks, including absence of voltage testing, must NEVER be done using these types of gloves.
