Proposed changes to Workplace Exposure Standards and Biological Exposure Indices
WorkSafe are outlining proposed changes to Workplace Exposure Standards (WESs) and Biological Exposure Indices (BEIs). Some of these will affect a number of operations in the New Zealand extractives sector.
The following substances are affected:
- Flour dust
- Hydrogen sulphide
- Nitrogen dioxide
- Propylene oxide
- Styrene
- BEIs – Arsenic (elemental and soluble inorganic compounds); Benzene; Carbon disulphide; Carbon monoxide; Chromium VI (hexavalent chromium), water-soluble fume; Ethyl benzene; Fluorides; Mercury (elemental); 4,4-Methylene bis(2-chloroaniline) (also known as MOCA, MBOCA); 4-4-Methylene diphenyl diisocyanate (MDI); Methyl isobutyl ketone (MIBK); Pentachlorophenol (PCP); Phenol; Tetrahydrofuran (THF); Toluene diisocyanate-2,4- or 2,6- or mixture of isomers (TDI); Toluene; Trichloroethylene (TCE).
Reviews for each of these proposed WESs and BEIs have been carried out by WorkSafe. There are separate proposal documents for each of the proposed WES and one proposal document that covers all of the proposed BEIs. The proposal documents and the submission document are located here: Proposed changes to Workplace Exposure Standards and Biological Exposure Indices
Please contact Wayne Scott if you would like MinEx to co-ordinate an industry submission on any of the proposed changes. wayne@minex.org.nz or 021 944 336.
