There are misconceptions sometimes as to what the items we wear out in the field and appurtenances constructed to satisfy safety requirements. Hard hats aren't designed to stop a wide flange beam dropping on your head if the beam were to fall from above, hard hats are designed to protect your head from small items like drywall screws falling from above while a wall is being constructed (just an example).
Temporary safety rails constructed around an elevator shaft isn't designed to stop you from falling down the shaft under any and all conditions, they will make you aware of the opening when you get near (just an example).
There are items you where that are designed to stop you from getting hurt, a safety harness comes to mind for fall protection.
Those gloves your referring to Raider, is a new one on me, I don't have that type of construction experience of working in a power plant. I'm sure they are being touted as and end all, be all, but me thinks they are design to prevent most types of injuries, but not all. Take it for what it's worth.
BTW, JMHO
