1 Identify and discuss three key features associated with the combustion of polymeric materials or compounds that are relevant to the safety and health of an EH&S or a FS professional responding to an incident involving these materials.

2 Air monitoring provides the following contaminant concentrations at the approximate center of a fire scene in which acres of automobile tires are burning: Carbon monoxide @ 1700 ppm; Carbon dioxide @ 7000 ppm; and Sulfur dioxide @ 600 ppm. Ignoring synergistic effects between these gases, which individual concentrations are considered life-threatening to the EH&S or FS professional responding to the scene? What combustion products are produced when materials made from polyacrylonitrile smolder and burn? What combination of properties is responsible for the selection of trinitrotoluene as a military explosive?

These answers have to be at least 200 words and written in APA format. I need this done by 10:30 p.m. tonight 9/2/14. If you can’t guarantee this please do not ask to do the work. If It is not returned by then I will not pay the remaining balance of what is owed.
