(a) The purpose of investigations under this part is to make available flame lamps that may be safely used for detecting the presence of methane and deficiency of oxygen in mine atmospheres. Lists of such lamps will be published from time to time in order that State mine-inspection departments, compensation bureaus, mine operators, miners, and others interested in safe equipment for the mines may have information regarding permissible flame safety lamps. This part supersedes Schedule 7B, issued September 19, 1922, and goes into effect August 30, 1935.

(b) Any flame safety lamp that meets the requirements of this part will be termed permissible by MSHA and if actively marketed will be listed as such in publications relating to permissible mining equipment.
