Whenever a provision of this chapter states that only that equipment or those processes approved by an agency or organization other than the department of labor and industries, such as the Underwriters Laboratories or the Mine Safety and Health Administration (MSHA) and the National Institute for Occupational Safety and Health (NIOSH), must be utilized, that provision must be construed to mean that approval of such equipment or process by the designated agency or group must be prima facie evidence of compliance with the provisions of this chapter.
