Oregon Occupational Safety and Health Division Oregon Administrative Rules AO 2-2017 Division 2 Note 2 to paragraph (8)(b): This paragraph does not require the employer to estimate the incident heat energy exposure for every job task performed by each employee. The employer may make broad estimates that cover multiple system areas provided the employer uses reasonable assumptions about the energy-exposure distribution throughout the system and provided the estimates represent the maximum employee exposure for those areas. For example, the employer could estimate the heat energy just outside a substation feeding a radial distribution system and use that estimate for all jobs performed on that radial system. - (c) The employer must ensure that each employee who is exposed to hazards from flames or electric arcs does not wear clothing that could melt onto their skin or that could ignite and continue to burn when exposed to flames or the heat energy estimated under paragraph (8)(b) of this rule. - Note to paragraph (8)(c) of this rule: This paragraph prohibits clothing made from acetate, nylon, polyester, rayon and polypropylene, either alone or in blends, unless the employer demonstrates that the fabric has been treated to withstand the conditions that may be encountered by the employee or that the employee wears the clothing in such a manner as to eliminate the hazard involved. - (d) The employer must ensure that the outer layer of clothing worn by an employee, except for clothing not required to be arc rated under paragraphs (8)(e)(A) through (8)(e)(E) of this rule, is flame resistant under any of the following conditions: - (A) The employee is exposed to contact with energized circuit parts operating at more than 600 volts, - (B) An electric arc could ignite flammable material in the work area that, in turn, could ignite the employee's clothing, - (C) Molten metal or electric arcs from faulted conductors in the work area could ignite the employee's clothing, or…

Division 2 AO 2-2017 Oregon Administrative Rules Oregon Occupational Safety and Health Division [redacted phone](8)(e) generally requires protective clothing and other protective equipment with an arc rating greater than or equal to the employer's estimate of available heat energy. As explained earlier in this appendix, untreated cotton is usually acceptable for exposures of 2 cal/cm 2 or less. If the exposure is greater than 6 that, the employee generally must wear flame-resistant clothing with a suitable arc rating in accordance with [redacted phone](8)(d) and (e). However, even if an employee is wearing a layer of flame-resistant clothing, there are circumstances under which flammable layers of clothing would be uncovered, and an electric arc could ignite them. For example, clothing ignition is possible if the employee is wearing flammable clothing under the flame-resistant clothing and the underlayer is uncovered because of an opening in the flame-resistant clothing. Thus, for purposes of [redacted phone](8)(c), it is important for the employer to consider the possibility of clothing ignition even when an employee is wearing flame-resistant clothing with a suitable arc rating. Under [redacted phone](8)(c), employees may not wear flammable clothing in conjunction with flame-resistant clothing if the flammable clothing poses an ignition hazard. Although outer flame-resistant layers may not have openings that expose 7 flammable inner layers, when an outer flame-resistant layer would be unable to resist breakopen, the next (inner) layer must be flame-resistant if it could ignite. 8 Non-flame-resistant clothing can ignite even when the heat energy from an electric arc is insufficient to ignite the clothing. For example, nearby flames can ignite an employee's clothing; and, even in the absence of flames, electric arcs pose ignition hazards beyond the hazard of ignition from incident energy under certain conditions. In addition to requiring flame-resistant cl…
