These Regulations implement Commission Directive 2009/161/EU (O.J. No. L 338, 19.12.2009, p.87) which establishes a third list of indicative occupational exposure limit values for exposure to chemical agents at work. They do so by amending the definition of “national occupational exposure limit value” in the Merchant Shipping and Fishing Vessels (Health and Safety at Work) (Chemical Agents) Regulations 2010 (“the 2010 Regulations”) so that it includes a reference to the list of indicative occupational exposure limit values in the Annex to that Directive (regulation 2, new paragraph (d)).
