141 Basildon Maternity Staff Sue NHS Trust Over Nitrous Oxide Exposure 30 Times Legal Limit

More than 100 Basildon Hospital maternity staff are suing Mid and South Essex NHS Foundation Trust after 141 claims alleged hazardous Entonox exposure between 2018 and 2023.
An internal report found nitrous oxide levels reached up to 30 times the legal workplace limit, with claimants blaming poor ventilation, leaking gas lines and equipment connections in the maternity unit.
Staff reported fatigue, headaches, anxiety, brain fog and low B12; court filings seek more than £1,500 each for personal injury, and the trust has already paid £89,000 in settlements.
A BBC-seen report said staff were not told for 16 months that tests had breached safety limits, reinforcing the trust's 2024 admission of unacceptable delays in addressing a serious risk.
The trust says it has improved gas monitoring and installed equipment to remove nitrous oxide from the air; the case is due back in court in July amid similar concerns at other English trusts.
