60
-A petroleum product used to start or enhance a fire -gasoline, kerosene, paint thinner
61
List some observations from the NOVA video.
62
-No common accelerant used -business types burned are the same (craft, furniture and fabric stores) -took place near a highway -point of origin was stuffing and pillows -occurred near times of firefighter conferences -time delay device was a used (match, cigarette, rubber band with paper,)

What are the disadvantages to alternative fueled vehicles?
68
-CNG compressor in fueling system is expensive. -Electric- initially more money, batteries are expensive, heavy and don’t last, recharging situations not in place yet. -H 2 / Fuel Cell- manufacturing and operating costs are high, and high quality H 2 is expensive. -Hybrid Gas/ Electric – Still produce some polluting emissions.
