who does the Medical Department Representative consult to determine the type of hearing protection devices to be used
Command IH survey
who does the Medical Department Representative report all permanent threshold shifts toward deteriorated hearing.
Safety officer
the Medical Department Representative report what information to the safety officer of those identified with permanent threshold shifts toward deteriorated hearing
name
rate/rank
work center
tome onboard
what are the responsibilities of the crew IRT HCP
Comply with noise hazard labels and wear hearing protection as required.
Undergo annual and any required follow-up audiometric testing if enrolled in the
HCP.
what are the program requirements of the HCP
Noise Measurement and Exposure Assessment
when are Noise Measurement and Exposure Assessment taken
part of the IH survey.
what is the Hazardous Noise warning decal, 8” X 10” number
NAVMD 6260/2
where will Noise warning decal be placed
posted to the outside doors/hatches leading into a hazardous noise
area.
what is the Hazardous Noise warning decal, 2” X 2” number
NAVMD 6260/2A
before implementing other methods of hearing loss prevention what must be done
Reduction of noise at the source must be explored first
when equipment that produce potentially hazardous noise should be what
modified to reduce noise levels wherever it is technologically and operationally feasible
when will modifications for noise abatement take place
during ship or equipment design, construction and testing.
Personnel working in or entering designated hazardous noise areas or utilizing noise hazardous tools or equipment shall shall have hearing protection devices at all times, and wear them without consideration of what
duration of exposure.
Areas or equipment where the noise level are equal to 84 dBA or lower require what type of hearing protection
none
Areas or equipment where the noise level are equal to 85 - 95 dBA require what type of hearing protection
single
Areas or equipment where the noise level are equal to 96 dBA or 165 dBP or greater require what type of hearing protection
double hearing
protection.
what personnel exposed to gunfire in a training situation or noise of a large caliber gun or missile firing, under any circumstance shall wear hearing protection.
All
what are the 3 hearing testing and medical surveillance
Reference Hearing Test
Monitoring hearing test
Termination hearing test
exposure to what noise level requires enrolment to HCP
96 dBA or greater
Record of noise measurements shall be kept by the measuring activity for how many years
50 years
what should be assigned to all potentially hazardous noise areas and operations
Risk Assessment Code (RAC)
All personnel entering into the naval service shall receive what type of audiogram
baseline
Hearing test done where shall not be used as a reference hearing test.
MEPS
what is a STS
Significant Threshold Shift
A change in hearing threshold relative to the current reference audiogram of an average of 10 dB or more in what Hz is considered a STS
2000, 3000, and 4000 Hz,
The STS may be what
positive
or
negative
a Positive STS means what
poorer hearing than the reference audiogram
a Negative STS means what
better hearing than reference audiogram
if there is a negative STS when should they retest
Retest the same day
negative STS same day retest show no STS what should assumed
that the monitoring audiogram was in error
negative STS same day retest still showed a negative STS what should be assumed monitoring audiogram was in error
Assume that the reference audiogram is
in error and Establish the retest as the new reference audiogram.
if there is a positive STS when should they retest
Retest after a 14 hour noise free environment to determine if the decrease of hearing is permanent
14 hour noise free environment may not be accomplished by what
use of hearing protection)
who should be notified of a STS
supervisor
If a positive STS retest does not indicate STS what should be done
Return to annual monitoring.
if a positive STS first retest shows a STS at 3000Hz and below what should be done
Screen for any medical issues through otoscopy and tympanometry.
otoscopy and tympanometry finding should be recorded where
SF 600
can second retest be administered on the same day as the first retest.
yes
if a second retest does not indicate a STS what should be done
Return to annual monitoring
if a second retest does indicate a STS what should be done
evaluate hearing protection
forwarded results to audiologist or qualified physician for review and
disposition.
if the results of a second positive STS are conclusive the results are used for what
create a re-established
reference audiogram
Supervisors should be notified in writing within how many days of a positive STS
21 days
Permanent Threshold Shift (PTS) toward poorer hearing. should ne reported to who
OSH office
Permanent Threshold Shift (PTS) toward poorer hearing. should ne reported to the OSH on what form
OPNAV 5102/7 Log of Navy Injuries
and Occupational Illnesses).
member is notified within how many days Permanent Threshold Shift (PTS) toward poorer hearing
21 days
workers signatures on what will suffice as appropriate notice
DD 2216
The physical exclusion period from noise is referred to as
auditory rest
how many hour auditory rest is usually sufficient to allow a temporary STS return to pre exposure level
14
what is the primary mean of noise abetment
engineering controls by means of engineering design
what is the second means of noise abatement
administrative control by limiting time of exposure and enforcing safe stay time
what are the other two abatement strategies in addition to engineering and administrative
Substitution of less noisy operations
Personal Hearing Protection Devices
wat are the types of hearing protection devices
Ear plugs
Disposable
Single flange
Double flange
Triple flange
Straightaway muffs
Circumaural Muff
when should personnel included in the hearing conservation program receive training
PRIOR to working in noise hazardous areas
Training shall also be conducted on an annual basis
Non-disposable hearing protectors require what
sizing and fitting conducted by trained medical personnel
Non-disposable hearing protectors require sizing and fitting will use Well-lighted visual inspection of the ear canal is necessary to determine
any condition is present that would make use of ear plug inadvisable
Each ear canal will be sized hw
separately
