Mr Steeds, who cleaned vents and lift shafts, discovered the dust he was exposed to contained dangerous levels of substances including asbestos, chromium, arsenic, silicates, and iron oxide. He won an employment tribunal earlier this year, which found his dismissal was unfair due to his "genuine and reasonable" belief that he and colleagues were in danger. Mr Steeds now believes all tube users should be aware of the risks, stating that hazardous waste was sometimes dumped on tracks and breathed in by passengers. Transport for London (TfL) maintains strict controls are in place to ensure safety from asbestos exposure and is currently considering the tribunal's findings.
