(ii) a person whose ability to do the measurements is verified by an approved asbestos inspection authority;

(2) In order to comply with the provisions of subregulation (l)(d), an employer shall ensure—

(b) that representative measurements contemplated in subregulation 1 (d) are carried out at least every 12 months: Provided that whenever the OEL for asbestos is exceeded, regulation 11 shall apply.
