4.13.1. Use-specific instructions
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.
4.13.2. 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.
- — Use product only in premises that are connected to a STP.

5. GENERAL DIRECTIONS FOR USE OF THE META SPC 1
5.1. Instructions for use
- — The duration of the effect is dependent on the performance requirements of the customer for their preserved material and on the specific ingredients composition and pH of the preserved product.
- — Always read the label or leaflet before use and follow all the instructions provided.
- — Respect the conditions of use of the product (concentration, contact time, temperature, pH, etc.)
PRECAUTIONARY MEASURES DURING STORAGE AND TRANSPORT:
Keep in a well-ventilated place. The product as supplied may evolve gas (largely carbon dioxide) slowly. To prevent the buildup of pressure the product is packaged in specially vented containers, where necessary. Keep this product in the original container when not in use. Container must be stored and transported in an upright position to prevent spilling the contents through the vent, where fitted.
5.2. Risk mitigation measures
-
5.3. Particulars of likely direct or indirect effects, first aid instructions and emergency measures to protect the environment
- — Skin contact: Remove contaminated clothing and shoes. Wash contaminated skin with water. Contact poison treatment specialist if symptoms occur.
- — Eye contact: Immediately flush with plenty of water, occasionally lifting the upper and lower eyelids. Check for and remove any contact lenses if easy to do. Continue to rinse with tepid water for at least 30 minutes. Call 112/ambulance for medical assistance.
- — Ingestion: Wash out mouth with water. Contact poison treatment specialist. Seek medical advice immediately if symptoms occur and/or large quantities have been ingested. Do not give fluids or induce vomiting.
- — Inhalation (of spray mist): Remove victim to fresh air and keep at rest in a position comfortable for breathing. Seek medical advice immediately if symptoms occur and/or large quantities have been inhaled.
- — In case of impaired consciousness place in recovery position and seek medical advice immediately.
- — Keep the container or label available.
5.4. Instructions for safe disposal of the product and its packaging
- — Do not discharge unused product on the ground, into water courses, into pipes (e.g. sink, toilets) nor down the drains.
- — Dispose of unused product, its packaging and all other waste, in accordance with local regulations.
5.5. Conditions of storage and shelf-life of the product under normal conditions of storage
Conditions for safe storage, including any incompatibilities: Keep in a dry, cool and well-ventilated place, in the original container.
Shelf-life: 12 months
Protect from sunlight.
Recommendation: If a metal packaging is used, a varnish layer should be applied.
