Carbon-containing materials can release appreciable quantities of carbon monoxid

Question

Carbon-containing materials can release appreciable quantities of carbon monoxide (CO) in fires. Likewise, materials that contain significant amounts of nitrogen can generate hydrogen cyanide (HCN) and nitric oxide (NO) Materials with chlorine or fluorine in their molecules can generate hydrogen chloride (HCl) and hydrogen fluoride (HF). Finally, some products generate large amounts of soot, which affects the visibility. Indicate in the following table (by marking the appropriate cells with an X) which toxic gas species are likely to be generated for the six types of polymeric materials that are listed. Also indicate whether you expect the combustion products to contain large amounts of soot. read the supplement material

Explanation / Answer

All of them will produce CO, and CO2 due to carbon content....

Then, for:

PP = polypropylene, Small soot amount

PVC = polyvynil chloryl, HCl gas

PS = polystyrene, soot,

PTFE = Polytetrafluoroethylene, HF mainly and small soot

Nylon = polyamide; NOx mainly,

Wood = cellulose, mianly... expect high amount of soot
