One person was taken to hospital and 28 others required treatment after a suspected chemical incident at the Jaguar Land Rover plant in Solihull.
West Midlands Ambulance Service (WMAS) sent its hazardous area response team to the scene on Sunday after several members of staff complained of feeling unwell following the application of floor sealant.
The workers were instructed to leave the site near Birmingham and remove their outer clothes in case of contamination, with some apparently being “hosed down”.
Posting on Twitter, the WMAS team said: “Our team alongside senior ambulance officers and ambulance crews responded to a suspected chemical incident at Jaguar Land Rover Solihull. Twenty-eight people were assessed and given advice at the site, with one person being transported to hospital with minor symptoms.”
Most of those who were assessed were said to have started feeling better once outside in the fresh air, with the crews having carried out its “remove, remove, remove” guidelines.
That involved telling those affected to get out of the immediate area, take off their outer clothing if affected, and remove any sign of the substance from their skin.
Signs of exposure to a hazardous substance can include odd smells and tastes, unexplained skin, eye or airway irritation, nausea, vomiting, twitching, sweating, disorientation and breathing problems.
The company employs around 10,000 people at their Solihull plant, but it announced last year that it would slash 1,000 jobs there because of plans to cut production at the site.
