1. Describe an incident (fire, spill, explosion, etc) you have experienced (or research one on the Internet, professional journal, or scientific magazine article) that involved a polymeric or explosive material(s) and required mitigation. Please do not use the instances supplied in the textbook unless you intend to provide a lot more detail than what is included in the book. The following items must be addressed:
A) Describe the incident and identify the polymeric or explosive material(s) involved;
B) Discuss the chemical interactions of the material(s) involved in this incident or hazardous properties relevant to the incident;
C) Discuss the mitigation required or implemented.
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?
