Which type of extinguisher can be used on all classes of fire?

A. Water

B. Foam

C. Class D

D. None of the above

Expert Solution

ANSWER:

EXPLANATION:

Water extinguishers are only used for Class-A type of fire (or fire due to combustible materials).

Foam extinguishers can be used for both Class-A and Class-B type of fires (Combustible materials and Flmmable liquids).

Class-D extinguishers uses a dry chemical which creates a barrier between the oxygen and the fuel element. Class-D extinguishers are usually designed for Class-D fires (fire due to inflammable materials), but they can be used as a multipurpose ABC extinguisher.

Note that it is usually not recommended to use Class-D extinguishers in an enclosed space, because the chemicals could be inhaled by the people nearby; although in some cases, it can be used for all ABC fires.

6.31. The exponential distribution can be used to solve Poisson-type problems in which the intervals are not time. The Air Travel Consumer Report published by the U.S. Department of Transportation reported that in a recent year, Virgin America led the nation in fewest occurrences of mishandled baggage, with a mean rate of 0.95 per 1,000 passengers. Assume that mishandled baggage occurrences are Poisson distributed. Using the exponential distribution to analyze this problem, determine the average number of passengers between occurrences....
