BCIT Reading Comprehension PreTest Practice- Part 2
Part 2 has 4 readings and 16 questions. You should be able to do all of the readings and score more than
65% (11/16 correct answers) in under 35 minutes.
If you do not score this well, we suggest that you get assistance to improve your reading speed and
comprehension skills. Among the many self-help programs available, the preparation books or kits for
the Scholastic Achievement Test (SAT) have proven effective. Other preparation kits that our students
have used successfully are the TOEFL (Test of English as a Foreign Language) and the International
English Language Testing System (IELTS). Public and school libraries, book stores, and the internet offer
these and more.
The Hazards of Excessive Heat
When the body heats too quickly to cool itself safely, or when you lose too much fluid or salt through dehydration or
sweating, your body temperature rises and heat-related illness may develop. Heat disorders share one common
feature: the individual has been in the heat too long or exercised too much for his or her age and physical condition.
Studies indicate that, other things being equal, the severity of heat disorders tends to increase with age. Conditions
that cause heat cramps in a 17-year-old may result in heat exhaustion in someone 40 years old, and in heat stroke in
a person over 60. Sunburn, with its ultraviolet radiation burns, can significantly retard the skin's ability to shed excess
heat. Acclimatization has to do with adjusting sweat-salt concentrations, among other things. The idea is to lose
enough water to regulate body temperature, with the least possible chemical disturbance--salt depletion.
The Heat Index, sometimes referred to as the apparent temperature, is given in degrees Fahrenheit. The Heat Index is a
measure of how hot it really feels when relative humidity is factored with the actual air temperature.
To find the Heat Index temperature, look at the Heat Index chart below. As an example, if the air temperature is 96°F
and the relative humidity is 65%, the heat index--how hot it feels--is 121°F
.
IMPORTANT: Heat index values were devised for shady, light wind conditions. Exposure to full sunshine can
increase heat index values by up to 15°F. Strong winds, particularly with very hot, dry air, can also be extremely
hazardous.
The Heat Index Chart shaded zone above 105°F shows a level that may cause increasingly severe heat disorders with
continued exposure or physical activity.
If the relative humidity is at 75%, what temperature puts you in extreme danger?
A.
B.
C.
D.
132°F
96°F
70°F
94°F
Exposure to full sunshine can increase heat values by as much as:
A.
B.
C.
D.
12°F
13°F
14°F
15°F
What conditions can affect heat related illness?
A.
B.
C.
D.
Age
Physical condition
Sunburn
All of the above
The heat index is a measure of:
A.
B.
C.
D.
The temperature of the earth

How hot it feels to your body
The boiling temperature of water
Aircraft Bolts
Aircraft bolts can be identified by an AN number. A breakdown of a typical bolt with an AN number
follows:
AN4-7
•
•
•
AN means the bolt is manufactured according to Air Force Navy specifications.
4 identifies the diameter of the shank in 1/16th inch increments
7 identifies the length of the shank in 1/8th inch increments
So, this particular bolt is a 1/4 inch diameter AN bolt that is 7/8 inch long measured from just under the
head to the tip of the shank. The bolt also has a drilled shank which means it can accept a cotter pin. Also,
bolt length may vary by + 1/32" to -1/64".
•
If the letter "e” follows the AN designation (ANe) that identifies a stainless steel bolt. The letter "H"
after AN (ANH) identifies a drilled head bolt. The letter “A” (AN4-7A) means the shank of the bolt is not
drilled.
AN Aircraft Bolt Dimensions
In constructing your airplane, you will not encounter many bolts larger than an AN8 (1/2 inch diameter). To
add a bit more confusion, if the dash number defining the length of the bolt has two digits, the first digit is
the length in whole inches and the second number is the length in additional 1/8" increments. In other
words, an AN5-14 bolt would be 1-1/2 inches long.
1. An AN3-6 bolt has a diameter of:
A.
B.
C.
D.
3mm
3/16 inch
3 inches
3/8 inch
2. The length of a bolt increases by increments of:
A.
B.
C.
D.
1/16”
1/8”
1/4”
3/8”
3. A bolt with a length designation 13
A. Is 13 inches long
B. Is 1-1/3 inches long
C. Is 13mm long
D. Is 1-3/8 inches long
4. If the bolt has an undrilled shank
A.
B.
C.
D.
It can accept a cotter pin
It has no threads
It requires lock wire
It cannot accept a cotter pin
Welding Equipment Set-Up
To avoid accidents, you must follow an organized procedure for assembling an oxyacetylene
unit.
1. Secure the cylinders in an upright position. A safety chain is commonly used to secure
cylinders to a portable cart so they do not tip over or get jarred (Figure 1). The cylinder
cart is designed to roll easily when tilted back on the wheels, yet be stable and secure
when stationary.
2. Remove the caps covering the cylinder valves once the cylinders are secured. The caps
match the size and colour of the cylinders. Oxygen cylinder caps may be red or green
and acetylene caps are black. Cylinder caps should always be in place when transporting
or storing cylinders.
3. Before attaching the regulators, “crack” the valves by opening them slightly, then
quickly closing them. This clears any dust or foreign particles from the valve outlets.
Stand to the side of the valve outlets and make sure they are not pointed toward you or
another person. Any particles inside the valves will be ejected with tremendous force.
4. Match the regulator connections to the cylinder valve connections. Start turning the nut
by hand (it should turn easily), then tighten it with a cylinder wrench. Do not force the
nut to start. If it is cross threaded it will not turn easily and the threads will be damaged.
Never over-tighten fittings. Remember, oxygen fittings have right-hand threads. Note
that the oxygen cylinder valve is externally threaded on the regulator connection, while
the acetylene valve is internally threaded.
Never lubricate fittings. Oil or grease combined with pressurized oxygen will
ignite and cause an explosion. Machined fittings need no lubrication.
5. Turn the pressure-adjusting screws out (counter clockwise) on both regulators. This
closes off the regulators so working pressure gauges are not permanently damaged
when high-pressure cylinder gases are allowed to flow through the valves.
6. Install reverse flow check valves (RFCVs) to regulator connections and tighten them.
Make sure to use RFCVs with correct arrow markings for the direction of gas flow. RFCVs
have left-hand or right-hand threads to match with corresponding connections.
7. Connect the hoses to the correct RFCV. The oxygen hose must be connected to the
right-hand threaded RFCV and the acetylene hose to the left-hand threaded RFCV. Avoid
over-tightening the fittings.
8. Turn the oxygen cylinder valve wheel counterclockwise very slowly to prevent damaging
the regulator. Watch the cylinder gauge. When maximum pressure is reached (the
gauge needle will stop), turn the valve all the way open until it stops.
9. Turn the acetylene cylinder valve wheel or wrench counterclockwise very slowly,
watching the cylinder gauge at the same time. When the pressure reaches maximum
pressure (when the needle stops), turn the valve ¼ to ½ turn more (this may vary
slightly) to maintain that pressure. The small amount of turning provides for a quick
closure of the valve should an emergency situation occur. If a cylinder wrench is used on
the acetylene cylinder valve, leave it on the valve. Note that when adjusting the cylinder
valves, working pressure gauges remain at zero.
Always stand to the side of the regulator and gauge faces in case the regulator fails.
10. Attach the RFCVs to the torch handle (remember to match the arrows to the direction of
the gas flow). Connect the hose to the RFCVs (Figure 2). According to the WCB, it is
advisable to use the RFCVs at both the torch handle and regulator hose connections.
Since RFCVs are sensitive and may become plugged, it is recommended that they be tested
once a week.
11. Place the welding tip on the torch handle and hand-tighten the nut. Never use wrench
or pliers to tighten the connection, as this can damage seals inside the tip.
12. Adjust the acetylene to correct working pressure first. Open the acetylene torch valve
no more than one turn. Turn (clockwise for higher pressure) the acetylene pressureadjusting screw until the working pressure gauge reads 3psi. This setting may vary, as
different tip sizes and torch designs require different pressures. Refer to manufacturer’s
specifications for correct settings. Next, close the torch valve gently, to prevent damage.
13. Follow the same procedure to adjust the oxygen to the correct working pressure. The
working pressure gauge should read 5 psi (again, this may vary).
The torch is ready to use, except there is always the possibility that one or more of the oxygen
or acetylene fittings may be leaking.

Leak Detection
With the cylinder valves open and gas flowing freely from the tank to the pressure regulator,
the working pressure gauge is set at 5 psi for oxygen and 3 psi for acetylene and the torch
valves are closed. The system is considered to be pressurized from the cylinders to the torch
valves and will remain so, if there are no leaks.
Before you start to use the torch, you should always check the line for leaks, whether the
equipment is being assembled for the first time or the set-up is used repeatedly. The line
should also be tested after any new cylinders or parts have been installed.
Larger leaks can be quickly detected by closing the cylinder valves after correctly setting the
working pressures. If a cylinder gauge shows a pressure drop, there is a leak. Smaller leaks may
be detected the same way, but it will take longer for the pressure drop to show on the gauge.
To quickly determine if a small leak is present, increase working pressures to 10 psi after
opening the cylinder valves. After adjusting the working pressure, close both cylinder valves
again and watch the cylinder pressure gauges for pressure drop. Make sure the torch valves are
closed.
If a gauge indicates a leak, use the following methods to pinpoint it:
1. Listen, smell and touch around connections, hoses and fittings for a leak.
2. If the leak cannot be found by those methods, apply a soapsuds solution to possible leak
areas (Figure 3). Bubble will appear if there is a leak.
Never use oil or flame near equipment when looking for leaks.
3. Repair the leak, if possible, then test the system again. When cylinder pressure readings
remain constant, the system is okay. Be sure to adjust back to recommended working
pressures after testing is done.
The equipment is ready for adjusting and lighting the torch.
Before lighting a torch the working PSI for
