Question Carbon-containing materials can release appreciable quantities of carbo

Question

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.

Explanation / Answer

1.polypropylene= CO2 and water.

2. from the combustion of PVC, the combustion products include CO( as asphyxiant), HCl( as pulmonary irritant) and some soot.

3 the combustion polypropylene in air produce( 200-600oC) CO, CO2, H2O and oxiginated hydrocarbons, aromatic and aliphatic hydrocarbons.soot also

4. PTFE=major product is CO2, significant amount of HF (Teflon), moderate amount of HCl( Neoflon)

5.nylon combustion products are, CO, CO2, HCN, H2O ,NH3 and NOx,

6. wood: CO, CO2, HIGH SOOT
