"It is a well-known phenomenon that because of the intensity of a large fire, the resultant plume of smoke and gas will contain a cocktail of harmful toxins."
Sailesh Mehta spoke to LBC Radio today regards the latest study that showed toxins had been found in and around Grenfell Tower. He said:
"Ideally, there should be a protocol after fires of such magnitude that would include toxicology reports and a mitigation strategy thereafter."
