21
Q

The written authorization to perform operations (such as welding, grinding, cutting, and electrical drilling) that are capable of providing a source of ignition

A

Hot work permit

22
Q

Oxygen-enriched atmosphere

23
Q

What percent of fatalities in confined spaces are untrained rescuers?

A

24
Q

What is the process of ensuring that space remains free from release of energy or other hazards while the space is open for entry operations?

A

Isolation

25
Q

Any atmosphere that poses an immediate threat to life or that is likely to result in acute or immediate severe health effects

A

Immediately Dangerous to Life or Health (IDLH)

26
Q

How often should testing occur?

A

Prior to daily use, or at least once per month

27
Q

Any space, other than a confined space, which is enclosed by bulkheads and overheads

A

Enclosed space

27
Q

The command’s overall program for controlling, and, where appropriate, for protecting personnel from permit space hazards and for regulating personnel entry into permit spaces

A

Permit-required confined space program

29
Q

Hot work will not be accomplished in or near spaces containing more than ___% of LEL.

A

10

30
Q

Step 1 of Evaluating Confined Space Hazards

A confined space must meet the following atmospheric criteria prior to entry:

A

1) Percent of oxygen not below 19.5% or above 22%
2) Percent of LEL not above 10%
3) Parts per million of carbon monoxide not above 35 parts per million (PPM)
4) Other atmospheric hazards not above the published permissible exposure limit (PEL)

31
Q

An atmosphere presenting a potential for death, disablement, injury, or acute illness from one of more of the following causes:

1) A flammable gas, vapor, or mist in excess of 10% of its lower explosive limit (LEL)
2) An oxygen-deficient atmosphere containing less than 19.5% oxygen by volume or an oxygen-enriched atmosphere containing more than 22% oxygen by volume
3) Airborne combustible dust at a concentration that meets or exceeds its LEL (airborne combustible dust which obscure vision at five feet or less)
4) Any other atmospheric condition that is immediately dangerous to life or health

A

Hazardous atmosphere

32
Q

Step 2 of Evaluating Confined Space Hazards

Visual inspection of the space prior to entry should identity other hazards that may exist

A

..

34
Q

Placing locks and tags on energy isolating devices to prevent the system from being re-energized while work is still being performed by personnel

A

Lockout-tagout

35
Q

Spaces bordering a subject space in all directions, including all points of contact, corners, diagonals, decks, tank tops, and bulkheads

A

Adjacent spaces

35
Q

The process by which the hazards, that may confront entrants of a permit space, are identified and evaluated

A

Testing

36
Q

Any action resulting in any part of an individual’s body breaking the plane of any opening of the confined space, and includes any work activities inside the confined space

A

Entry

36
Q

How long is a copy of a permit required to be maintained following an entry?

A

3 months

37
Q

What is the primary means of eliminating atmospheric hazards?

A

Ventilation

38
Q

How often should compressed cylinders be visually and hydrostatically inspected?

A

Visually inspected monthly, and hydrostatically tested ever 12 years

39
Q

What is the optimum oxygen level?

A

20.8%

40
Q

An atmosphere having an oxygen concentration of less than 19.5% by volume

A

Oxygen-deficient atmosphere

40
Q

Any condition in a permit space that is not allowed by the permit during the period when entry is authorized

A

Prohibited condition
