(b)	when observed or recorded with such instrument or device as the Director-General may approve, to be darker than shade No. 1 on the Ringelmann Chart; or
(c)	to be of such opacity as to cause obscuration to a degree equivalent to smoke darker than shade No. 1 on the Ringelmann Chart.

(2) Section 11 of the Act shall not apply to the emission of dark smoke from any chimney where —

(a)	the emission of dark smoke is for a duration of less than 5 minutes in any period of one hour in a day; and

Methods of smoke indication

3.—(1) Every occupier of any industrial or trade premises in or on which any industrial plant or fuel burning equipment is situated shall, if required by the Director-General to do so, provide or install such instrument, equipment or device in or on the premises in accordance with paragraphs (2) and (3).

(2) The instrument, equipment or device referred to in paragraph (1) must be of such type and installed in such manner as will enable any person in charge of the industrial plant or fuel burning equipment to readily ascertain at all times and without leaving the boiler room, furnace room or control room, whether smoke is being discharged from any chimney on the industrial or trade premises.

(3) The instrument, equipment or device may include one or more of the following:

(a)	a smoke density indicator, recorder and alarm which will provide adequate indication in the boiler room, furnace room or control room of the density of smoke being discharged from the chimney;
(b)	a closed circuit television installation with the receiver located in the boiler room, furnace room or control room; or
(c)	any other instrument, equipment or device approved by the Director-General.

Standards of concentration of air impurities
