HC Deb 13 February 1922 vol 150 c658W
Sir H. NORMAN

asked the Home Secretary if there is any limit to the percentage of carbon monoxide in gas supplied for domestic use; if his Department is kept informed of the actual percentage in gas supplied; and, if so, will he state what it is in typical cases?

Mr. BALDWIN

I have been asked to answer. There is no statutory limitation of the proportion of carbon monoxide in gas supplied for domestic purposes. Information is obtained from time to time by the Board of Trade from which it is possible to estimate the proportion of carbon monoxide in the gas. There are very few cases in which it would appear that the proportion would exceed 20 per cent., and generally speaking the proportion is considerably below that figure.
