HC Deb 18 July 1963 vol 681 c76W
32. Mr. MacDermot

asked the Minister of Housing and Local Government and Minister for Welsh Affairs when he expects to reach a decision upon the effectiveness of certain experimental fume arresters installed at a metal foundry in Cannock Chase.

Mr. Corfield

The arrestment plant was given its first trial run in April last. There have been teething troubles since, caused mainly by corrosion and metal fatigue. I cannot yet say when a final assessment of this pioneering project will be possible.
