NHS Staff Exposed to Cancer-Causing Chemical

Thousands of NHS staff are at risk due to exposure to formaldehyde, a cancer-causing chemical comparable to asbestos. Research indicates that seven in 10 NHS pathology departments in the UK have exceeded the European Union's eight-hour workplace exposure limits for formaldehyde. These findings emerged from an analysis of airborne monitoring results and follow concerns raised by former NHS workers about high exposure levels.

The chemical, used for preserving tissue samples and in various industrial applications, is classified as carcinogenic by the International Agency for Research on Cancer. Studies link long-term exposure to nasal tumours, leukaemia, and damage to the respiratory, reproductive, and nervous systems.

While the EU implemented a binding workplace limit of 0.3 parts per million (ppm) over eight hours in 2021, the UK, post-Brexit, retains a higher limit of two ppm. Researchers advocate for aligning UK limits with EU standards, citing infrequent monitoring and frequent exceedances of the EU limit in UK labs.

Urgent regulatory action, including infrastructure upgrades, regular monitoring, employee education, and improved personal protective equipment, is recommended to enhance occupational hygiene in NHS pathology departments. Experts also stress the need for common guidelines for formaldehyde control and monitoring within the NHS.
