EVOTECH ARC FLASH FULL BODY HARNESS
MSA premium EVOTECH Arc Flash Harness provides outstanding arc flash protection for utility company employees and contractors who work at heights. Its rugged design looks good on the job and is 30% lighter than comparable harnesses. Made from 100% Kevlar® webbing, the EVOTECH Harness is fire-resistant, so it maintains its performance in the event of a fall after an arc flash. The inherent properties of the harness help to maintain its color, making formal inspection easy. Designed to provide more comfort for the user, our Kevlar shoulder padding has no binding edge. Our patent-pending horizontal leg strap design conforms to the user’s body for increased support.
- Harness is lighter — by more than 1 lb — than comparable harnesses
- Moisture-wicking padding keeps users cooler
- Non-binding edge shoulder padding prevents neck chafing
- 100% Kevlar webbing is fire-resistant and self-extinguishing
- Reflectivity on shoulder padding provides increased visibility in low-light applications
- Patent-pending horizontal leg straps stay in place, providing more mobility and comfort
- RFID capability
- ASTM F887 tested with fire-resistant (FR) properties
- Meets CSA Z259.11 requirements
- OSHA 1910.269 & 1926 Subpart V compliant
Understanding Arc Flash
Arc flash - also known as arc fault or arc blast - is a dangerous release of energy created by an electrical fault. An arc flash is a phenomenon where a flashover of electric current leaves its intended path and travels through the air from one conductor to another, or to the ground. The results are often violent; serious injury and even death can occur as a result. Arc flash can be caused by:
- Dropping tools
- Accidental touching
- Material failure
- Faulty Installation
Three factors determine the severity of an arc flash injury:
- Proximity of the worker to the hazard
- Time for circuit to break
ASTM F887 Test requirements
The ASTM F887 standard outlines performance requirements of fall protection products for arc flash resistance. One requirement of the standard is that the webbing material must have a 7,000 lb tensile strength, which is higher than typical full body harness webbings found on the market. Additionally, the harness is put through an Electric
Arc Performance test that requires the product to self-extinguish within five seconds after being subjected to an arc flash and cannot melt or drip. Lastly, the harness is put through an ANSI Z359 drop test using a 282 lb test torso and must be able to meet the drop test requirements.
Arc Flash (AF) rated Products
When working conditions exist where people are subjected to potential hazards of extreme heat generation that could produce an arc flash, it is critical, particularly when working at heights, to use fall protection systems that not only resist AF exposure, but can perform in a fall situation as well.
AF rated products are designed to resist heat from an electrical arc flash. AF designated products have been tested to the applicable standards to maintain the required level of strength and performance with the ability to resist heat. Always look for the Arc Flash symbol for easy identification.
