The performance of every automatic contrivance to prevent overwinding as required by Regulation 7 of the Coal and Other Mines (Shafts, Outlets and Roads) Regulations, 1956, should be critically examined forthwith having regard to the results of the investigation of the overwind which is the subject of this Report.

Effective steps should be taken forthwith to eliminate the deficiencies that are found in any automatic contrivance to prevent overwinding.

The Code of Testing the Safety Equipment of Winding Engines which the National Coal Board have nearly completed should be reviewed in consultation with the manufacturers of winding engines and safety equipment. The Code should be modified Where necessary in the light of this Report and then applied without delay to the winding engines at the Board's mines. Copies of the Code should be made available to the owners of other mines where winding engines with automatic contrivances are used.

The safety equipment of every winding engine should be constructed, tested and maintained so that nothing can prevent any part of the equipment from taking that action by which it fulfils its purpose.

The advantages and disadvantages of using dynamic, regenerative or other electrical braking in conjunction with mechanical braking that is applied slowly when the automatic contrivance of an electric winding engine trips during that portion of a wind where normally the cages move quickly, should be reviewed at an early date in the light of this Report and of modem practice both in this and other countries.

Every emergency push button should be situated so that the winding engineman can easily and readily operate it from the place where he normally controls the winding engine.

Appropriate and effective steps should be taken where still necessary to prevent grease or oil from being deposited on the brake paths of every winding engine.

The safety catches in any headframe should be adequately supported and arranged so that they may be readily examined, tested and maintained in proper working order.

Effective arrangements should be made at every mine to ensure that any change in the telephone number or address of any official or person who must be notified of any emergency is circulated and posted where necessary at the appropriate time.
