HC Deb 04 March 1968 vol 760 c38W
Mr. William Edwards

asked the Minister of Power whether he will seek to introduce periodic lung-function tests for slate workers and other quarry workers.

Mr. Freeson

No. The responsibilities of my right hon. Friend arise from the Mines and Quarries Act, 1954, and he does not consider that this would be an appropriate measure for him to introduce under that Act.
