All the obligations in the EU legislation mentioned in MSN 1888(M+F) Amendment 3, which have affect in the UK prior to the 1st January 2021, are retained in UK law, with any necessary modifications, after the end of the EU Exit implementation period.

Amendment 3 updates references only.

The Merchant Shipping and Fishing Vessels (Health and Safety at Work) (Chemical Agents) Regulations 2010 (SI 2010/330) (the “Chemical Agents Regulations”) introduced requirements for the protection of workers from the risks related to exposure to hazardous chemical agents at work.

The Health and Safety Executive (“HSE”) and the Health and Safety Executive for Northern Ireland (“HSE(NI)”) have implemented similar protection from these risks through the Control of Substances Hazardous to Health Regulations 2002 (as amended) and the Control of Substances Hazardous to Health Regulations (Northern Ireland) 2003 (as amended) respectively (referred to in this notice jointly as “COSHH”).

The chemical agents regulations ensure the protection of seafarers and workers on ships, including fishing vessels, yachts and other small vessel of all types with workers on board, including those operating on inland waters.

This notice provides detailed information required to comply with the chemical agents regulations. Details are at paragraph 17.

It also seeks to provide general guidance to assist shipowners and employers in identifying, by means of risk assessments, any risks to those working on board as a result of exposure to chemical agents, which could have an adverse effect on their health and safety.

Where such risks are identified, the shipowner or employer must take appropriate measures to either remove those risks entirely or, where that is not possible, reduce them as far as is reasonably practicable.
