6. "Arc Rating" - ATPV or E_BT

"When garments are made with a different number of fabric layers in different areas of the garment, the arc rating for each area shall be designated. Pockets, trim, closures, seams, labels and heraldry shall not be considered as extra layers"

All Arc Flash garments are not created equal!!!
F1959 details the standardized test method, which must be employed to determine the thermal protective value of a textile material in an Electrical Arc application.

• Stoll Curve - curve used to predict the onset of a second degree burn
• Requires a minimum of 20 test data points
• Arc Rating:
  • ATPV: defined as the minimum incident thermal energy that causes the onset of a second degree burn when Stoll is reached without breakopen occuring
  • E_BT: defined as the average of five or more highest incident exposure energy values (without breakopen) below Stoll when breakopen occurs before reaching Stoll
  • We DO NOT recommend using E_BTAS because you will not be in compliance with F-1506 nor NFPA 70E and a second or third degree burn could result using this value. E_BTAS by definition is a rating above Stoll (occurence of second degree burn). E_BTAS is used primarily in the Rainwear standard (ASTM F1891).

Flame retardant clothing is a requirement!!!
"The employer shall ensure that each employee who is exposed to the hazards of flames or electric arcs does not wear clothing that, when exposed to flames or electric arcs, could increase the extent of injury that would be sustained by the employee." Not: Employee shall not wear clothing made from the following types of fabrics, either alone or in blends: acetate, nylon, polyester, rayon.
Clarifications - June 1994 - Employers must make a determination of whether or not 100% cotton or wool clothing worn by a worker is acceptable under the conditions to which the worker could be exposed. Clothing made from flame retardant or flame resistant materials, in accordance with ASTM F1506, is acceptable under the rule.

Clothing used must prevent second degree burn!!!
The protective clothing selected for a particular application shall have an arc protective rating (E_BT or ATPV) higher than the hazard to prevent the onset of a second degree burn

• Flash hazard analysis shall be done before a person approaches a hazard
• Employees working in areas where there is an electrical hazard shall be provided with, and shall use, appropriate protective equipment
• The entire flash suit, including the window, shall have energy absorbing characteristics that are suitable for the arc-flash exposure.
