[1] He held significant posts in the mining, gas and coke industries both in South Yorkshire and nationally.
[3][a] Later in the war Brass was appointed Divisional Commander of Special Police for the Staincross Division of Yorkshire and became a Military Representative on Tribunals.
[3] In 1929 Brass was a member of the committee which examined the issues surrounding the replacement of rail mounted tubs with conveyor belts.
[3] On Saturday 22 September 1934 at 2:08 a.m. a violent explosion ripped through the Dennis section of Gresford Colliery.
[8] The official finding, as presented by the commissioner Sir Henry Walker, viewed with suspicion shot firing activities.
The other assessor, Mr Joseph Jones, was concerned about a possible firedamp build up on one of the faces which was ignited by an accident with a safety lamp or from a spark from a mechanised coalcutter.
He surmised that the explosion could have been caused by a gas build on one of the main access tunnels which was ignited by the telephone being called.
