The COSHH Regulations are The Control of Substances Hazardous to Health Regulations 2002 (SI 2002/2677), which impose duties on employers and employees concerning the use of dangerous substances. They originally applied to non-sea-going UK ships but contained a disapplication to sea-going ships, i. e. ships that go beyond categorised waters. However, The Control of Substances Hazardous to Health (Amendment) Regulations 2004 (SI 2004/3286) extended the disapplication to all ships other than Royal Navy ships.
