Should Metal Closures be used in Arc Rated Clothing

The question of whether metal closures should be used on arc rated clothing is raised regularly by end users especially in relation to zippers and press studs. Hugh Hoagland from e-Hazard in the US recently posed the question “Can a shirt with a metal snap or a metal zipper meet ASTM F1506 and NFPA 70E?”. Hugh’s answer “This is a matter of opinion and there is some controversy about the issue”. So there appears to be no conclusive answer to this question so we thought we would clear up how and why Elliotts have approached this issue.
