4.23.1. Use-specific instructions for use
Microbiological tests to prove adequacy of preservation have to be undertaken by the user of C(M)IT/MIT products in order to determine the effective dose of the preservative for the specific matrix/location/system. If needed, consult the manufacturer of the preservative product.
4.23.2. Use-specific risk mitigation measures
- — Rinse the system (especially the dispensing pumps) with water prior to perform the cleaning step.
- — During handling phases (mixing and loading) and cleaning of the dispensing pumps, exposure to the product (corrosive and skin sensitizer product) has to be limited by use of PPE and application of technical and organisational RMM:
- — Minimisation of manual phases (process automation);
- — Use of a dosing device;
- — Regular cleaning of equipment and work area;
- — Avoidance of contact with contaminated tools and objects;
- — Good standard of general ventilation;
- — Training and management of staff on good practice.
- — PPE is as follows:
- — protective chemical resistant gloves (glove material to be specified by the authorisation holder within the product information);
- — protective coverall (at least type 3 or 4, EN 14605) which is impermeable for the biocidal product shall be worn (coverall material to be specified by the authorisation holder within the product information);
- — Eye protection;
- — Substance/task appropriate respirator if ventilation is inadequate.
- — The use of C(M)IT/MIT (3:1) containing products for the slimicide treatment in the wet-end stage of the paper manufacturing process is restricted to
- (a) curative treatments in plants connected to a slimicide-free water from a pulp mill and only for the treatment of the short circulation of the paper mill; and
- (b) preventive treatments,
and, for both cases, only if the factory’s waste water is purified in an on-site (full) industrial sewage treatment plant with a minimal capacity of 5 000 m3 per day as described in the Industrial Emission Directive 2010/75/EU (Best Available Techniques for the production of pulp, paper and board) and if a dilution of at least 200 times in surface water is achieved after the industrial sewage treatment plant.
