87. Mr. David Adams
asked the Secretary for Mines whether the number of mechanically-driven auxiliary fans in coal mines in Great Britain has increased during the past year; and whether, in view of the dangers attending the use of these fans, he will take special steps to ensure that ventilation surveys are carried out wherever possible before such a fan is installed and also to ensure that the motor 2717 and switchgear of the fan, when installed, are covered by a Buxton certificate?
§ Captain Crookshank
The number of electrically-driven auxiliary fans showed an increase of 67 during the year ended 3oth June, 1937, as compared with the previous year. Electrically-driven auxiliary fans are mainly used in Scotland, and the divisional inspector has dealt fully with the subject in his recently published annual report for 1937, and made recommendations, including those made by the hon. Member. The question of strengthening the existing law will be a matter for consideration when the report of the Royal Commission is received.
