Answer 3

Safety valve.

Question 4

Whats the function of the air transformer (regulator)?

Answer 4

Remove oil/water from air and regulate pressure to the inflation device.

Question 5

Answer 5

Drain petcock

Question 6

What is your primary goal after flotation equipment passes a leak test?

Answer 6

Completely deflate.

Question 7

What can be used as part of a mobility package to deflate flotation equipment?

Answer 7

Industrial portable vacuum cleaner.

Question 8

Describe a vacuum hose you use to deflate flotation equipment.

Answer 8

Light to medium weight, crush resistant, safety colored yellow material.

Question 9

What type of air nozzle do we use to inflate flotation equipment and clean dust from sewing machine motors?

Answer 9

OSHA approved self relieving safety tape.

Question 10

Name three air pressure indicators.

Answer 10

Water manometer, life raft test fixture, and 1.5 PSI gauge.

Question 11

What are manometers used for?

Answer 11

Inspect poopi suits when required to pressurize to required inches of water column.

Question 12

What may happen if you open both the air supply and feed valves of a test fixture at the same time?

Answer 12

PSI pressure gauge may over pressurize and break.

Question 13

For water manometers, how does 28 inches of water compare to PSI?

Answer 13

Its = to 1 PSI.

Question 14

How can you use a PSI gauge to obtain a direct reading of pressure on the multi-place rafts.

Answer 14

Install gauge to topping off valve of one flotation tube and air supply line to the other.

Question 15

What is the function of the dial push/pull gauge?

Answer 15

Measure tension and compression.

Question 16

When you pull from the top of a push/pull gauge what direction does the red indicator pointer rotate?

Answer 16

Clockwise.

Question 17

How do you set a new zero index?

Answer 17

By rotating the bezel of the dial indicator.

Question 18

How do you ensure accurate readings?

Answer 18

Maintain firm grip on the gauge.

Question 19

What are four main components of the triple beam scale?

Answer 19

Round platform, aft poise bar with poise block, beam pointer, and forward poise bar with poise block.

Question 20

What is the marked range on the aft poise bar?

Answer 20

0-1000g

Question 21

What is the approximate weight of an LPU-10/P CO2 cylinder?

Answer 21

143.5g

Question 22

What happens when you move the poise blocks or the CO2 cylinder without holding the beam pointer centered?

Answer 22

The triple beam scale will slam up or down.

Question 23

What factors do you consider when determining a location for the digital scale within a flotation equipment section?

Answer 23

Put it on a sturdy level surface out of direct sunlight.

Question 24

Which display key allows you to switch between the decimal pound and kilograms setting?

Answer 24

UNITS

Question 25

When weight checking a one man life raft CO2 cylinder, what components must be on the weighing pan?

Answer 25

CO2 cylinder, cable ball assembly, adapter clip, and universal adapter.

Question 26

What is the correct setting for the aft poise block when weighing an LPU-10/P CO2 cylinder?

Answer 26

100g notch.
