21. Restriction of exposure to ionising radiation

 

 

1) Every holder of an authority and every public conveyer shall, with regard to any activity he may undertake with a Group IV hazardous substance, with due regard to the dose limits prescribed in Annexure 2, take all necessary steps to restrict the extent to which employees and other persons may be exposed to ionising radiation.

 

2) Without derogating from the generality of subregulation (1), every holder shall, as far as is reasonably practicable, achieve the restriction of exposure to ionising radiation required under that subregulation by means of warning notices, controls and the design of facilities for shielding, ventilation, the containment of Group IV hazardous substances and the minimising of contamination, and further by providing and using safety mechanisms and warning devices.

 

3) In addition to taking the precautions required by subregulation (2), every holder shall provide such systems of work as will restrict the exposure of employees and other persons to ionising radiation and, in the case of employees or other persons who enter or remain in controlled areas, equip these persons with personal protective equipment.

 

4) Every holder shall ensure that all personal protective equipment referred to in subregulation (3) and equipment containing a Group IV hazardous substance, and other equipment used in work with such substance, is properly maintained.

 

5) An employee who is engaged in work with a Group IV hazardous substance--
a) may not, with due regard to the dose limits prescribed in Annexure 2, knowingly expose himself or any other person to ionising radiation to a greater extent than is necessary for the purposes of his work, and shall exercise reasonable care while carrying out such work;
b) shall make full and proper use of any personal protective equipment provided in terms of subregulation (3); and
c) shall forthwith notify his employer of any defect he may discover in any of the equipment specified in subregulation (4).
