Arc guide & info

Usage & Care

For full body protection, PC shall be worn close/fastened and other suitable PC & PPE shall be used (e.g. helmet and face screen, gloves with cuffs, footwear etc.) Sleeves must NEVER be rolled up during use of the garment. Each item must be of an equal or higher arc rating than that required by the Arc Flash protection boundary rating. For repairs/alterations, only Flame Retardant fabric and thread must be used. No undergarments which can melt should be used. PC & PPE must be stored in a dry, clean and ventilated area. Wear only clean, unsoiled and undamaged Protective Clothing and PPE. All garments should be washed in accordance with manufacturer’s instructions (available on request). Where garments are being laundered by external laundry companies, care should be taken to ensure that correct laundry procedures are being followed. We recommend Service Matters, an independent laundry company, who can provide this specialised laundry service to you. Failure to launder properly could adversely affect the integrity of the garment.

ARC rating explained







Lyngsoe ARC garments have CAT 4 ARC rating – the highest possible.

ARC Rating Explained

A value of the energy necessary to pass through any given fabric to cause with 50% probability a second or third degree burn. This value is measured in calories/cm². The necessary Arc Rating for an article of clothing is determined by a Hazard/Risk Assessment and the resulting HRC. Usually measured in terms of ATPV or EBT. Simple put the ARC rating determines the protective characteristics of the fabric. The higher the ARC rating value the greater the protection. When the product is sold to protect workers from arcing faults, clothing manufacturer are required in indicate the ARC rating.

Arc Flash

An explosive release of energy caused by an electrical arc. An arc flash results from either a phase to ground or a phase to phase fault caused by such occurrences as accidental contact with electrical systems, build up of conductive dust, corrosion, dropped tools, and improper work procedures. During an arc flash, the temperature can reach 35,000° Fahrenheit, and exposure to an arc flash can result in serious burn injury and death.
