Commission Implementing Regulation (EU) 2023/2704of 28 November 2023granting a Union authorisation for the single biocidal product GHC Chlor(Text with EEA relevance)

Commission Implementing Regulation (EU) 2023/2704 of 28 November 2023 granting a Union authorisation for the single biocidal product GHC Chlor (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EU) No 528/2012 of the European Parliament and of the Council of 22 May 2012 concerning the making available on the market and use of biocidal products OJ L 167, 27.6.2012, p. 1. , and in particular Article 44(5), first subparagraph, thereof, Whereas: (1) On 10 December 2018, GHC Gerling, Holz & Co. Handels GmbH submitted to the European Chemicals Agency (the Agency) an application in accordance with Article 43(1) of Regulation (EU) No 528/2012 and Article 4 of Commission Implementing Regulation (EU) No 414/2013 Commission Implementing Regulation (EU) No 414/2013 of 6 May 2013 specifying a procedure for the authorisation of same biocidal products in accordance with Regulation (EU) No 528/2012 of the European Parliament and of the Council (OJ L 125, 7.5.2013, p. 4). for authorisation of the same single biocidal product, as referred to in Article 1 of Implementing Regulation (EU) No 414/2013, named GHC Chlor of product-types 2 (disinfectants and algaecides not intended for direct application to humans or animals) and 5 (drinking water) as described in Annex V to Regulation (EU) No 528/2012. The application was recorded under case number BC-EN045705-33 in the Register for Biocidal Products (the Register). The application also indicated the application number of the related reference single biocidal product Arche Chlorine, recorded in the Register under case number BC-UQ045679-98. (2) GHC Chlor contains active chlorine released from chlorine as the active substance, included in the Union list of approved active substances referred to in Article 9(2) of Regulation (EU) No 528/2012, for product-types 2 and 5. (3) On 3 August 2021, the Agency submitted to the Commission its opinion ECHA opinion of 3 August 2021 on the Union authorisation of the same single biocidal product GHC Chlor (https://echa.europa.eu/opinions-on-union-authorisation). and the draft summary of the biocidal product characteristics (SPC) of GHC Chlor in accordance with Article 6(1) and (2) of Implementing Regulation (EU) No 414/2013. (4) In its opinion, the Agency concludes that the differences, proposed by GHC Gerling, Holz & Co. Handels GmbH, between the same biocidal product and the related reference biocidal product are limited to information which can be the subject of an administrative change in accordance with Article 11 of Commission Implementing Regulation (EU) No 354/2013 Commission Implementing Regulation (EU) No 354/2013 of 18 April 2013 on changes of biocidal products authorised in accordance with Regulation (EU) No 528/2012 of the European Parliament and of the Council (OJ L 109, 19.4.2013, p. 4). , and that based on the assessment of Arche Chlorine and subject to compliance with the draft SPC, the same single biocidal product meets the conditions laid down in Article 19(1) of Regulation (EU) No 528/2012.

(5) On 15 June 2023, the Agency transmitted to the Commission the draft SPC in all the official languages of the Union in accordance with Article 44(4) of Regulation (EU) No 528/2012. (6) The Commission also considers that the request made by Germany to adjust the conditions of the Union authorisation of the single biocidal product Arche Chlorine for its territory in accordance with Article 44(5), second subparagraph, of Regulation (EU) No 528/2012 also applies for the uses 2, 3 and 4 of GHC Chlor. This adjustment is justified in recitals 7 to 9 of Commission Implementing Regulation (EU) 2023/754 Commission Implementing Regulation (EU) 2023/754 of 12 April 2023 granting a Union authorisation for the single biocidal product Arche Chlorine in accordance with Regulation (EU) No 528/2012 of the European Parliament and of the Council (OJ L 100, 13.4.2023, p. 83). granting a Union authorisation for the single biocidal product Arche Chlorine in accordance with Regulation (EU) No 528/2012. (7) The Commission concurs with the opinion of the Agency and considers it therefore appropriate to grant a Union authorisation for the same single biocidal product GHC Chlor with the adjustments of the SPC as requested by Germany for its territory for the uses 2, 3 and 4 in accordance with Article 44(5), second subparagraph, of Regulation (EU) No 528/2012. (8) The expiry date of this authorisation is aligned to the expiry date of the reference single biocidal product Arche Chlorine. (9) The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on Biocidal Products, HAS ADOPTED THIS REGULATION:

Article 1

Risk mitigation measures For connecting or disconnecting the product containers as well as for maintenance or repair of the gas pipe system, the following risk mitigation measures (RMMs) are mandatory: an alarm system (trigger value corresponding to the acute exposure concentration (AEC): 0,5 mg active chlorine/m3 (or lower according to national legislation) which initiates safety procedures like wearing respiratory protective equipment (RPE) according to CEN standard EN14387: Respiratory protective devices – Gas filter(s) and combined filter(s) – Requirements, testing, marking (or equivalent);

application of local exhaust ventilation (LEV) (according to the national legislation) and low-pressure/vacuum are in place to avoid chlorine emission; the electrochemical sensors used for measurements to detect various chlorinated species in addition to chlorine itself; sensors to measure exposure also when the operators are using RPE according to CEN standard EN141 or equivalent. 5.3. Particulars of likely direct or indirect effects, first aid instructions and emergency measures to protect the environment Avoid breathing this toxic gas as much as possible. IF INHALED: Move to fresh air and keep at rest in a position comfortable for breathing. Immediately call 112/ambulance for medical assistance. Information for healthcare personnel/doctor: Immediately initiate life support measures, thereafter call a POISON CENTRE. IF SWALLOWED: Not applicable. IF ON SKIN: Take off all contaminated clothing and wash it before reuse. Wash skin with water. If skin irritation occurs: Get medical advice. IF IN EYES: Rinse with water. Remove contact lenses, if present and easy to do. Continue rinsing for 5 minutes. Call a POISON CENTRE or a doctor. 5.4. Instructions for safe disposal of the product and its packaging At the end of the treatment, dispose of unused product and the packaging in accordance with local requirements. Do not discharge unused product on the ground, into water courses, into pipes (sink, toilets…) or down the drains. 5.5. Conditions of storage and shelf-life of the product under normal conditions of storage Storage conditions: Airtight pressure tanks: Due to its chemical and physical properties, chlorine gas is always stored in dedicated carbon/steel recipients with special, dedicated valves. Chlorine packages for use within the EU should be constructed and labelled according to Directive 2010/35/EU of the European Parliament and of the Council (5) and the Agreement concerning the International Carriage of Dangerous Goods by Road (ADR) done at Geneva on 30 September 1957. See section 6 for further reference. Maximum filling 1,25 kg/l (80 % of volume approx.). Keep containers with chlorine tightly closed and store in a cool, dry and well-ventilated place. Tightly screw on the valve outlet protection seal and the valve protection cap when storing. Prevent cylinders from falling over. Protect from heat and direct sunlight, the temperature of the container should never be below 15 °C or above 50 °C. Chlorine should be kept away from reactive products (materials to avoid: reducing agents, combustible materials, metals in powder, acetylene, hydrogen, ammonia, hydrocarbons and organic materials). 6.
