I am not clear as to why you are being asked to do this. The smoke from burning modern furnishings and structural components is highly toxic,containing among other things hydrogen cyanide and carbon monoxide. Therefore the normal response is to leave the area. Fire fighters will have breathing apparatus, so are protected. There is a lot of literature about the toxicity of smoke. Here is one http://www.ncbi.nlm.nih.gov/pubmed/12184505 Obviously anything that can put the fire out is good thing, but people should still evacuate so as to avoid breathing the smoke. Sprinklers will reduce the quantity of smoke, but not eliminate it.
