Title Reducing the ignition risk from auxiliary fans.
Bibliographic information Sep. 1980, p.147-149. 8 ref.
Abstract Following a colliery explosion probably due to ignition from friction of an all-steel auxiliary ventilation fan, a committee was set up to consider all aspects of the ventilation of narrow drivages including the design, maintenance and methods of installation of auxiliary fans. Work carried out at the Explosion and Flame Laboratory of the Health and Safety Executive included the examination of the frictional ignition hazard likely to arise from the use of certain combinations of metals in the manufacture of fans, and has shown that a practical solution to the problem would be to retain the mild steel impeller but to make the casing of leaded (60/40) brass.
