Question

Following new research from the University of Southampton - which found that working or travelling on an underground railway for a sustained period of time could have serious health implications due to the high level of airborne metals inhaled - will you now adopt the precautionary principles put forward by the Institute of Occupational Medicine and others who suggest that employers should aim to keep exposure to 'respirable' and 'inhalable' dust below 1 mg/m3 and 5 mg/m3 respectively?

TfL measures air quality regularly on the Tube and results show dust levels are consistently below the Workplace Exposure limits set by the Health and Safety Executive (HSE) as the enforcing body. They are also below the guidance levels recommended by the Institute of Occupational Medicine (IOM), at 1 mg/m3 and 5mg/m3 for 'respirable' and 'inhalable' dust respectively.
