Description

Works in which scrap metals are treated in any type of furnace for recovery of metal with a processing capacity exceeding 50 kg per hour, where this is the primary object of the works.

Works in which the processing capacity exceeds 5 000 tonnes per annum and in which metallurgi- cal slags or pulverised fuel ash or minerals are subjected to any size reduction, grading or heat- ing by processes giving rise to dust, including the subsequent handling of the products of any such process.

Works in which the installed capacity exceeds 0.5 tonne per hour and which are used for the destruc- tion by burning of wastes or refuse.

Works in which the processing capacity exceeds 200 tonnes per annum, and in which- (a) any products of pertroleum are prepared or used, except as solvent, in any chemical manufacturing process, not being a chemical manufacturing process described in any other specified process; or

(b) used lubricating oil is prepared for re-use by

any thermal process.

Works in which the installed capacity exceeds 1 000 tonnes per annum and in which the manu- facture of sulphuric acid is carried on by any process, and works for the concentration or distil- lation of sulphuric acid.

Works of the following kinds in which the in- stalled capacity exceeds 3 000 tonnes per annum, and in which-

(a) gas tar or coal tar is distilled or is heated in

any manufacturing process; or

(b) creosote or any other product of distillation of gas tar or coal tar is distilled or is heated in any manufacturing operation.

Works in which the installed furnace capacity exceeds 1 tonne and in which frit is made by fusion of minerals and quenching.

Works in which the installed capacity exceeds 0.4 tonne or, if the mode of operation is continuous 0.25 tonne per hour, and in which by the applica- tion of heat, lead is extracted from any material containing lead or its compounds and works in which compounds of lead are manufactured from metallic lead or its compounds by dry processes which give rise to dust and fumes.

Works in which the processing capacity exceeds 1000 tonnes per annum and in which-

(a) any methylamine or any ethylamine is made;

or

(b) any methylamine or any ethylamine is used

in any chemical process.

Works in which the installed capacity exceeds 200 tonnes (expressed as asbestos) per annum and in which the preparation and fabrication of asbestos is carried out.
