The Pottery (Health and Welfare) Special Regulations 1950

Ventilation

15.—(1) In the case of every workroom there shall be provided for the admission of fresh air into the room sufficient inlets suitably placed and so constructed or with such arrangements as to prevent a draught blowing directly from the inlet onto a worker.

(2) (a) The drying of pottery articles by means of heat shall, save as provided in sub-paragraphs (b) and (c) of this paragraph, be carried on only in drying stoves or in rooms set apart for that purpose.

(b) In so far as compliance with the foregoing requirement is not reasonably practicable by reason of the nature or size of the article or through lack of space, pottery articles may be left to be dried in a workroom, provided that in any such case (except where sub-paragraph (c) of this paragraph applies) ventilation shall so far as reasonably practicable be so arranged that there is not a flow of air towards the workers from the direction of the sources of artificial heat used for drying the articles.

(c) In the case of a workroom in which sanitary fireclay ware is dried by heat arising from the floor or from pipes near the floor, the requirements of sub-paragraph (b) of this paragraph shall not apply but the arrangements for ventilating the room shall, so far as reasonably practicable, be such as to facilitate the vertically upward movement of air from the articles being dried.

(3) Every drying stove, dryer and mangle shall be so ventilated that there is no flow of hot air from the stove, dryer or mangle into any place where any person works.

(4) In the case of vertical or tower mangles the pipes used for heating shall not be fixed below the level of the top of any opening at which workers put in or take off ware.

(5) The requirements of this Regulation shall be without prejudice to the provisions of Section 4 of the principal Act.
