Who takes noise measurements to measure levels of noise at different sites?

Industrial Hygienist and or Occupational Audiologist

Perfectly

How long should records of noise measurements be kept by the measuring activity?

50 years

What code is assigned to all potentially hazardous noise areas and operations?

Risk Assessment Code (RAC)

How many days after should IH's resurvey after any significant modifications or changes in work routine which could impact the noise exposure level?

30 days

Baseline audiograms are done when?

Bootcamp or entering into the naval service

HCP personnel are required to have a hearing exam…

ANNUALLY

What does STS stand for?

Significant Threshold Shift

What is considered an STS?

A change in threshold compared to the current reference audiogram of 10dB or more at 2k, 3k, or 4,000 Hz in either ear

What does a Positive STS mean?

Worse hearing

What does a Negative STS mean?

Better hearing

What do you do if the STS is negative?

Could mean either the reference/monitoring audiogram may be in error ## Footnote **Retest the same day**

If retest showed no STS, what do you do?

Assume the monitoring audiogram was in error

If retest still showed improved hearing, what do you do?

Assume that the reference audiogram was in error ## Footnote **Establish the retest as the new reference audiogram**

If STS is positive what do you do?

Retest after 14 hours noise free Notify supervisor (so they can rest)

If retest does not indicate STS when do they get another audiogram?

Return to annual monitoring

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

Screen for any medical issues Record findings on SF600

If findings are abnormal upon ear exam what do you do?

further evaluation f/u until medically cleared

If findings are normal upon ear exam what do you do?

Perform 2nd retest

If STS is positive can a 2nd retest be administered on the same day as the first retest?

Yes

What if 2nd retest showed STS?

- Hearing protection is evaluated - Results are forwarded to audiologist - 2nd retest are used as re-established reference audiogram - Supervisor notified

The Safety Officers maintains records of:

* Noise hazardous areas * Noise hazardous equipment * Baseline and subsequent IH surveys

Supervisors must be notified in writing within how many days of positive STS?

21 days

What happens if a Permanent Threshold Shift (PTS) towards poorer hearing is identified?

* Reported to the OSH office for entry on OPNAV 5102/7 (Log of Navy Injuries and Occupational Illnesses) * Worker is notified within 21 days (signature on DD 2216 will suffice as appropriate notice)

Workers must be notified within how many days of positive STS?

21 days | (signature on DD 2216 will suffice as appropriate notice)

Noise Free Audiogram is also called what?

Auditory Rest

What is the purpose of the auditory rest?

To allow sufficient time for temporary STS to return to pre-exposure levels

How long is auditory rest?

14 hours

What are Noise Abatement Strategies?

* Engineering Controls * Administrative Controls * Substitution * PPE

What are Engineering Controls?

**Primary means of protection** * Noise barriers * Engineering design to eliminate/reduce noise level

What are Administrative Controls?

**Secondary** Limit times of exposure/ enforce safe stay time

What is Substitution?

Switch out for less noisy equipment

What is PPE?

Hearing protective devices

What are the 2 types of Hearing Protective Devices?

Ear plus & Muffs

What are the 4 types of ear plugs?

1. Single flange 2. Double flange 3. Triple Flange 4. Disposable

What are the 2 types of muffs?

1. Straightaway Muffs 2. Circumaural Muffs

Training Requirements for personnel in the HCP:

- Must receive training PRIOR to working in noise hazardous areas - Must receive annual training thereafter

Non-disposable hearing protectors require what?

* sizing and fitting * must be conducted by medically trained personnel
