Health Canada has evaluated the aspects of concern that prompted the special review of pest control products containing iodocarb (3-iodo-2-propynyl butyl carbamate) used in metalworking fluids. Based on the evaluation of the aspects of concern, Health Canada is proposing for public consultation the continued registration of iodocarb used in metalworking fluids and its associated end-use products registered for sale and use in Canada.
Iodocarb is an antimicrobial used as a material preservative (including paints, adhesives and caulks, paper coating, plastic, textiles, and liquid detergents) and industrial fluids preservative (metalworking fluids). It is also used as a joinery wood preservative and sapstain control chemical. For this special review, currently registered products containing iodocarb that are used as preservatives in metalworking fluids were considered and are listed in Appendix I of PSRD2024-02, Proposed special review decision for iodocarb (3-iodo-2-propynyl butyl carbamate) and its associated end-use products.
The evaluation of available relevant scientific information related to the aspects of concern indicated that iodocarb used in metalworking fluids showed acceptable risk when iodocarb is used according to the proposed conditions of registration, which includes new mitigation measures summarized below.
To protect workers (mixers/loaders) from exposure when treating metalworking fluids with iodocarb: when open pouring products containing iodocarb into metalworking fluid, the proposed maximum amount of iodocarb handled per day is limited to 1.25 kg a.i./person. If handling more than this, a closed transfer (injection) system is required.
To protect secondary workers (machinists) from exposure to iodocarb-treated metalworking fluids: a maximum concentration of iodocarb in metalworking fluid of 750 ppm.
For a full list of products containing iodocarb that are used as preservatives in metalworking fluids, please consult Appendix I in the Proposed Special Review Decision or visit the Pesticide Label Search database.
