Five fire crews and two specialist teams contained a chemical spill at a commercial premises on Gladys Avenue in Portsmouth, Hampshire, on 25 February 2026. The emergency response was triggered in the early afternoon, leading to local road closures and safety warnings for people living nearby.
Firefighters from Cosham, Southsea, and Portchester arrived at the scene at approximately 1:30 PM to investigate and manage the leak. They were supported by hazardous materials units from Winchester and Romsey, according to the Hampshire & Isle of Wight Fire & Rescue Service.
During the incident, police officers closed off Gladys Avenue and North End Avenue to manage traffic and keep the public safe. Residents in the immediate area were advised to stay indoors and keep all windows and doors closed to avoid breathing in any airborne fumes.
Paramedics attended the scene to provide medical help to several individuals who suffered from mild inhalation of the chemical fumes. No serious injuries were reported, and those affected were treated on-site without needing to go to the hospital.
The specialist teams successfully contained the spill and made the commercial premises safe by 4:09 PM. Once the area was declared secure, the road closures were lifted and residents were able to open their windows again.
