Deck 13: Pressure Hazards

Question 1

A swift return to the surface from diving or decompression during high-altitude flight may cause lung rupture.

Answer 1

True

Question 2

A boiler is an open vessel in which water is heated to form steam, hot water, or high temperature water under pressure.

Answer 2

False

Question 3

Safety hazards associated with boilers and other pressurized vessels include the following except:

A) Human error
B) Mechanical errors
C) Design errors
D) Proper operator training

Answer 3

D

Question 4

Pressure is the force exerted against an opposing fluid or thrust distributed over a surface.

Question 5

Which of the following is not an inert gas?

A) Helium
B) Argon
C) Oxygen
D) Neon

Question 6

The least effective preventive measure for overcoming potential pressure hazards is proper design.

Question 7

Approximately 79% of the atmosphere is oxygen, with the other 21% being nitrogen.

Question 8

Which of the following situations may cause a vacuum?

A) Shock waves
B) Pressures below the atmospheric level
C) High-temperature water
D) Ultrasonic waves

Question 9

Ultrasonic and X-ray waves are forms of destructive testing methods used to detect cracks or leaks.

Question 10

Boyle's law states that the product of a given pressure and volume is constant with a constant temperature.

Question 11

Pressure is the force exerted against an opposing fluid or thrust distributed over a surface.

Question 12

Atmospheric pressure is usually measured using a:

A) Pressure vessel
B) Ultrasound meter
C) Barometer
D) Vacuum gauge

Question 13

Boyle's law states that the product of a given pressure and volume is constant with a constant temperature.

Question 14

A) Boyle's law
B) OSHA standards
C) ASME codes
D) Dalton's law

Question 15

To reduce pressure hazards, keep pressurized hoses as long as possible.
