Yes

Question 26

what are four primary stages of fire

Answer 26

Incipent Smoke Flame Heat

Question 27

What causes most fires in a datacenter

Answer 27

overloaded electrical outlets.

Question 28

What suppression material is used for class A fire and what type of material is in a Class A fire

Answer 28

water, soda acid | common combustibles

Question 29

What suppression material is used for class B fire and what type of material is in a Class B fire

Answer 29

CO2, soda acid, Halon | liquids

Question 30

What suppression material is used for class C fire and what type of material is in a Class C fire

Answer 30

CO2, Halon | electrical

Question 31

What suppression material is used for class D fire and what type of material is in a Class D fire

Answer 31

dry powder | metal

Question 32

always full of water. Water discharges immediately when suppression is triggered.

Answer 32

Wet pipe or closed head system

Question 33

contains compressed air. Once suppression is triggered, the air escapes, opening a water valve that in turn causes the pipes to fill and discharge water into the environment.

Answer 33

dry pipe

Question 34

uses larger pipes and therefore delivers a significantly larger volume of water. these systems are inappropriate for environments that contain electronics and computers.

Answer 34

deluge system

Question 35

combination dry pipe/wet pipe system. The system exists as a dry pipe until the initial stages of a fire (smoke, heat, and so on) are detected, and then the pipes are filled with water. The water is released only after the sprinkler head activation triggers are melted by sufficient heat. If the fire is quenched before sprinklers are triggered, pipes can be manually emptied and reset. This also allows manual intervention to stop the release of water before sprinkler triggering occurs.

Answer 35

preaction system

Question 36

What are the most appropriate water-based system for environments that house both computers and humans together.

Answer 36

preaction system

Question 37
