758. Stills to be securely closed.
- There shall be no opening into any still except those in connection with the charging and discharging pipes, condensers, mandoors, and air cocks or valve upon the breast of head. The external orifice of an air valve must be so constructed and covered by a perforated metal plate as to make it impracticable by means of it either to introduce wash or abstract spirit, or to convey spirit vapour away for condensation elsewhere.
