asked the Parliamentary Secretary to the Ministry of War Transport in view of the danger of poisoning by carbon monoxide from producer-gas vehicles, what special steps are being taken to warn those concerned of this danger?

A note on the possible danger from carbon monoxide has been sent recently to every operator of public service vehicles which are driven by producer-gas. The danger is also explained in the Manual of Instructions which will be distributed with each producer-gas unit allocated to operators of goods vehicles.
