The UK government, Scottish Government, Welsh Government and Northern Ireland Executive should work with employers, including health boards and trusts, to review the availability of qualified fit testers and take steps to increase the number of fit testers accordingly. Availability should be reviewed every three years in line with the Inquiry's Module 1 Report (Recommendation 4). The Health and Safety Executive and the Health and Safety Executive for Northern Ireland should update their guidance to employers to emphasise the need to ensure that sufficient fit-testing capacity is available.
