There are some categories of workers who require specific surveillance due to the nature of their employment:

• Workers exposed to sensitising agents are required to have lung function tests (Spirometry).
• Vision tests are required for some categories of employee. VDU/DSE users are required to be provided with screening for middle distance vision (Display Screen Regulations 1992). Similarly colour vision for a checker, distance vision for a driver, and peripheral vision for a fork lift truck driver.
• Forklift truck drivers are required to have checks which cover HSE requirements for standards of physical and mental health. Specifically vision, hearing, mobility, blood pressure and urine sample check.
• Night workers are required to have a fitness check which covers conditions which could be exacerbated by working at night.
