Chemistry of Fires and Explosions
1. What are recommendations that NFPA 654 has for controlling dust to prevent explosions?
2. Explain what is meant by the Performance-Based Design Option. Why is it necessary?
3. What NFPA standard is used for Explosion Protection
4. What NFPA standard is used to determine the class and group for electrical equipment?
5. What is Fugitive dust
6. What type of detector is required when fire detection is incorporated into the process?
7. What types of things would go into an Inspection, Testing, Maintenance Program for facilities that have combustible dust?
8. What are the classes of flame retardant chemicals and what are the mechanisms of each in preventing or delaying fire ignition and/or growth?
9. What is the mission of the North American Fire Retardant Alliance? Who do they represent? What is their connection to the American Chemistry Council?
10. According to the Green Science Policy Institute (and other similar organizations) what is the concern with flame retardant chemicals?
11. What classes of flame retardant chemicals pose this concern? Which ones do not present a concern?
12. What are Persistent Organic Pollutants? Why is this a global concern?
13. Explain what is meant by the term ‘bioaccumulation’? Why are animals at the top of the food chain most susceptible to hazards?
14. Using NFPA 2001 and referring to the Clean Agent Fire Suppression presentation, determine the weight of HFC-227ea required to protect an enclosure 20-ft wide, 40-ft long, and 8 ft high at an ambient temperature of 60 F and an elevation of 6000 ft, using a 9% design concentration.
