Two people were taken to hospital after emergency services were called to a chemical spillage in Saham Toney.
Fire crews from Watton and Dereham, a heavy rescue pump from King's Lynn and the environmental protection unit from Sprowston were called to the chemical incident in a building in Bell Lane just before 9.45pm on Saturday.
Firefighters were at the scene until about 11pm. Gas monitors were used to check the air quality, but no further action was required.
An East of England Ambulance Service spokesman confirmed that an ambulance crew and an ambulance officer attended Bell Lane following reports that a man was having breathing difficulties.
The spokesman said: 'They treated a man, believed to be in his 30s, and a child, who were taken to Norfolk and Norwich University Hospital as a precautionary measure.'
Breckland police confirmed they were also at the incident with the ambulance service.
The police took to Twitter to say: 'Currently on scene at Chemical Incident in Saham Toney with @Norfolkfire & @EastEnglandAmb #ReadTheLabel #LessonsToBeLearnt #Teamwork'
