Read the following paragraghs and answer questions 9 through 13.
If arson is a suspected cause of a fire it is important to ensure the proper preservation & collection of potential evidence at the scene. Fire investigators are typically responsible for gathering such evidence. If the investigator is not available, it is especially important for the firefighters on scene to take the necessary steps to salvage & collect potential pieces of evidence once the fire has been extinguished & the overhaul phase of the fire begins.
The fire department has the authority over a fire scene for as long as necessary to ensure a proper & thorough investigation. When the last Firefighter leaves the scene, the department’s authority is surrendered. Often a search warrant or written consent is required to re-enter or investigate the scene at a later time. For this reason it is important that all the evidence be tagged, marked & photograghed as soon as possible. If there is any doubt that further investigation may be needed it is important to leave personnel at the scene and the scene should be properly cordoned off with "DO NOT ENTER TAPE". As many firefighters should remain as necessary to guard the scene, to ensure scene safety and prevent residents and bystanders from entering the area. Under no circumstances should any body be allowed to enter the scene unless accompanied by a fire officer. Any entry, even by the owner of the premises, should be carefully logged. The persons name, time of entry, time of departure, description of any items taken & reason for entry should all be recorded.
9) If an investigator is not available what should firefighters do to assist in the investigation?
a) Salvage & collect evidence b) Tag, mark & photograph evidence c) It is not the firefighters responsibility, therefore they should simply extinguish & overhaul the fire. d) Begin the investigation themselves with the evidence they have collected e) both A & B
10) The fire department has the authority at a fire scene for how long?
a) Anywhere from 1-3 weeks b) Until the investigation is complete c) Until the last Firefighter leaves the scene d) Until the evidence is all collected e) Until the owner arrives
11) Evidence is usually collected during what phase of the fire?
a) suppression phase b) salvage phase c) overhaul phase d) extinguishment phase e) final phase
12) All of the following are true EXCEPT?
a) Search warrants are never needed to enter a fire scene. b) Salvaging & collecting evidence is always the responsibility of the fire investigator. c) Entrance to the fire scene must be recorded. d) Guards are sometimes required to protect the scene. e) The fire department has the authority of a fire scene for as long as necessary.
13) Entry into the fire scene is allowed.
a) only to the owner b) only to the owner if accompanied by a fire officer c) only to the owner if accompanied by a fire officer & entry is recorded properly d) only if accompanied by a fire officer & entry is recorded properly

A) Friction B) Gravity C) Inertia D) Distance
20) Back Pressure, sometimes referred to as Head Pressure, is measured in lbs per square inch (psi). The back pressure of water is .434 per foot of elevation. If the height of a water tank is 180 feet, what is the back pressure going to be at the bottom of this tank.
A) 7.8psi B) 78.1 psi C) 80.6 D) 88.1
See Answer Key below for answers & a brief explanation.
1) B (12). Solve by cross multiplying: 30/100 = ?/40
2) C (8,330). 40% of 2500 is 1,000. 1,000 x 8.33lbs = 8,330lbs
3) D (1 11/15). You must first convert the fraction to an "improper fraction" then multiply. You end up with 13/3 x 2/5 = 26/15 which is reduced to 1 11/15.
4) C ($175). $14 x 8 = $112, 3 x $21 = $63. $112 + $63 = $175.
5) A (36) The question asks for cubic yards, but the measurements are given in feet. You must first convert feet to yards then multiply 4 x 3 x 3 = 36 cubic yards. Tricks like this exist on many tests. Always read carefully & be on the lookout for such trick questions.
6) B (1/5). .20 is equal to 1/5. Again you can cross multiply to find the answer. 20/100 = ?/20. Answer 4/20 which reduces to 1/5.
7) C (178ft 9in). 3 1/4 x 55 = 13/4 x 55/1 = 178 3/4 ft, which equals 178ft 9in
8) D (15,618lbs). The tank is 1,000 cubic feet, therefore there are approx 7,500 gallons in the tank. To fill the tank it needs 1/4 its capacity, which is 1,875 gallons. This weighs 15,618.75lbs
9) e 10) c 11) c 12) a 13) d
14) C (42.5%). The range of the aerial is equal to 102ft - 55ft = 47ft. If it is was raised to 75 ft, 20 ft of the ladders 47 ft range is being used. Cross multiply & solve for X to get the percentage. 20/47 = x/100 = 42.5%.
15) A (Aerial ladder platform) It's range is only 25 ft.
16) C 17) C 18) D 19) A 20) B
