Protecting the face and head region from arc flash hazards is crucial. The faceshield and helmet combination does the job effectively and barely restricts movement or causes an inconvenience.
The faceshield is designed to deflect blast energy away from the face, while absorbing any heat and spatter. The helmet is simply a mounting device for the faceshield, but is made of similar material. Standard faceshield and hardhats WILL melt in an arc flash; only use approved PPE.
A new add-on for the faceshield is the Nomex flap. The flay attaches to the bottom of the face shield, and hangs down to the chest. This creates a mechanical barrier between to cover the gap between the faceshield and chin area.
Although the faceshield / helmet achieve their 10ka/1sec Arc Flash rating without this flap, it is an approved extra feature suitable for some applications.
