Question

Which fire protection system would be most appropriate for an unconditioned warehouse located In Chicago if the warehouse contains materials such as paper, wood and other type A combustibles?A. Wet pipe system
B. Dry pipe system
C. Deluge system
D. Clean agent system

Answer 1

Answer:

A. Wet pipe System

Explanation:

For fires as a result of type A combustibles, any technique can be used to either starve, or smother the fire.

Consider the large size of the warehouse, since most fire protection systems can get the job done, a key determining factor will now be cost.

The Wet pipe or water sprinkler system is the most cost effective as it can be easily installed and maintained in large buildings. This is because it does not need other resources apart from running water which is already available in the building.

As a result, the wet pipe system is apt for such a warehouse.

Answer 2

Answer:

B

Explanation:

Dry pipe system

Dry pipe sprinkler systems as the name implies are not filled with water, These sprinkler systems are intended for applications where the ambient temperature cannot be kept at a minimum of 40°F at all times. Dry pipe sprinkler systems can be commonly found in areas prone to freezing, such as the following:

Unheated warehouses

Commercial freezers

Unconditioned attics

Water-sensitive storage areas

The main advantages of dry pipe sprinkler systems are

ADVANTAGES

1) They are good for industrial and commercial spaces where piping is exposed to freezing temperatures.

2) The system iwill not rust since there is no water inside the pipes under normal conditions.

3) Sine it does not use water in the piping, surface condensation and dripping are less likely. This is a key advantage in areas where water-sensitive materials are stored.
