Just looking for some insight on climbing helmets that are suited for line clearance work. I'm not around power a lot but figure I should be wearing the right one when I am.
Also, don't wear a sponge soaked in a saline solution under your helmet.
Z89.1-1997 also changed the alpha designations for the classes of electrical performance.
Class G (General) Helmets - This Is Equivalent To The Old Class A. Class G Helmets Are Proof Tested At 2,200 Volts.
Class E (Electrical) Helmets - This Is Equivalent To The Old Class B. Class E Helmets Are Proof Tested At 20,000 Volts.
Class C (Conductive) Helmets - This Class Provides No Electrical Insulation; The Alpha Designation Did Not Change From The Old Standard.
"The brain feels numb. Bright lights dance and flash. Your head feels abnormally large. A heavy weight appears to bear down on your head. You feel as if you were treading on air, with everything around you a blank. You are alone--the only being, the only object, the only tangible thing in the universe. You gradually sink into insensibility."[11]
