A

Single hearing protection and placement in HCP.

32
Q

Noise levels equal to 96 dBA or greater require what?

A

33
Q

Industrial Hygienist and/or Occupational Audiologist take noise measurements to measure levels of noise where?

A

At different sites.

34
Q

Noise levels equal to 85 dB or greater (continuous or intermittent), or 140 dB peak sound level of impact or impulse noise,

Should be what?

A

Analyzed to determine the potential hazard,

Resurvey 30 days after any significant modifications or changes in work routine which could impact the noise exposure level.

35
Q

A

50 years.

36
Q

What shall be assigned to all potentially hazardous noise areas and operations?

A

38
Q

Hearing test done at MEPS shall not be used as a what?

A

Reference hearing test.

39
Q

Recorded on DD-2216.

40
Q

What is an STS?

A

Significant Threshold Shift (STS),

A change in hearing threshold relative to the current reference audiogram of an average of 10 dB or more at 2000, 3000, and 4000 Hz in either ear.

41
Q

Positive STS?

A

Poorer Hearing.

42
Q

Negative STS?

A

Better Hearing.

43
Q

If the STS is negative, the hearing levels of the monitoring audiogram are better than the reference audiogram, what could be the cause?

A

Either the Reference or monitoring audiogram may be in error.

44
Q

If a patient has a negative STS, when do you retest them?

A

The same day.

45
Q

If the negative STS retest showed no STS, assume what?

A

That the monitoring audiogram was in error.

46
Q

If the negative STS retest still showed improved hearing, assume what?

A

That the reference audiogram is in error.

47
Q

If retest still showed improved hearing, assume that the reference audiogram is in error, and establish what as the new reference?

A

The retest as the new reference audiogram.

48
Q

When do you retest a positive STS?

A

Retest after a 14 hour noise free environment,

May not be accomplished by the use of hearing protection,

To determine if the decrease of hearing is permanent.

49
Q

If a patient has a positive STS who should be notified?

A

Their supervisor.

50
Q

If a positive STS retest does not indicate STS, return to what?

A

Annual monitoring.

51
Q

If first positive STS retest showed STS and if frequencies below 3000 Hz are involved,

Screen for any medical issues through what?

A

Otoscopy and tympanometry.

52
Q

When do you HCP data on an SF 600?

A

A positive STS with frequencies below 3000 Hz.

53
Q

If first retest showed STS and if frequencies below 3000 Hz are involved,

If findings are abnormal, what needs to happen?

55
Q

Second audio retest can be administered when?

On the same day as the first retest.

56
Q

If the retests does not indicate STS,

The patient returns to what?

Results of the second retest are typically used to create what?

A

A re-established reference audiogram.

59
Q

Supervisors should be notified in writing within ____ days of positive STS?

A

21.

60
Q

A Permanent Threshold Shift (PTS) toward poorer hearing is reported to who?

A

Reported to the OSH office,

61
Q

What form number is,

Log of Navy Injuries and Occupational Illnesses?

A

OPNAV 5102/7.

62
Q

Within how many days is a worker notified of a permanent threshold shift?

A

Worker is notified within 21 days,

Worker’s signature on DD2216 will suffice as appropriate notice.

63
Q

What is a Noise Free Audiogram?

A

The physical exclusion period from noise is referred to as “auditory rest”.

64
Q

The 14 hour “auditory rest” is usually sufficient to allow what?

A

A temporary STS to return to pre-exposure levels.

65
Q

Noise Abatement Strategies:

Engineering Controls?

A

Primary means of protection,

Construction tools and equipment with various and many Noise Barriers or dampening (Acoustical enclosures),

Engineering design to eliminate or reduce the noise level of machinery, equipment, and other operating devices.

66
Q

Noise Abatement Strategies:

Administrative Controls?

A

The secondary means of protection,

Limiting times of exposure/enforcing safe stay time.

67
Q

What is the third and fourth noise abatement strategies?

A

Substitution of less noisy operations,

Personal Hearing Protection Devices.

68
Q

What are the Personal Hearing Protective Devices?

A

Ear plugs,

Straightaway muffs,

Circumaural Muff.

69
Q

What are examples of ear plugs?

A

Disposable,

71
Q

HCP training will be conducted when?

A

Training shall also be conducted on an annual basis.

72
Q

Hearing Protective Device Fitting:

Non-disposable hearing protectors require what?

A

Sizing and fitting.

Conducted by Medically trained personnel.

73
Q

Well-lighted visual inspection of the ear canal is necessary to determine whether any condition is present that would make use of ____ inadvisable?

A

Ear plug.

74
Q

Each ear canal will be sized how?

A

Separately.
