The Panel approved amendments to Schedule B and corresponding policy language to better reflect current scientific/medical knowledge and the system of occupational disease recognition in B.C. The Panel also amended the "Description of Disease" to include unilateral thickening as well as benign pleural effusion (unilateral and bilateral). In addition, the requirement that the thickening be "5mm thick and extending over more than a quarter of the chest wall" was removed. Corresponding changes were made to the policy language for this Item (RSCM #29.47). The effective dates of this amendment will be 30 days after first publication in the Gazette.
