5-3 Hearing Conservation Flashcards
CO Responsibility
Establish an effective Hearing Conservation Program
Safety Officer Responsibilities
Establish an effective Hearing Conservation Program
Division Officer
(a) Ensures proper noise hazard labeling of spaces and equipment.
(b) Ensures proper personnel training.
(c) Sends designated personnel for audiograms
MDR
Conducts training for all hands during INDOC (initial) and annually thereafter on
the Hearing Conservation Program
List of Training topics for HCP
1) Effects of hazardous noise.
2) Designated noise hazardous areas and equipment
3) Proper use and maintenance of HPDs.
4) The necessity for hearing testing.
5) Mandatory requirement to wear assigned hearing protection.
6) Off-duty hearing health hazard.
7) The effects of hearing loss on career longevity.
8) Communication in high-noise environments.
Who is informed of all PTS toward deteriorated hearing?
Safety Officer
Information reported to Safety Officer
1) Name
2) Rate/Rank
3) Work Center
4) Time onboard
All hands
Comply with noise hazard labels and wear hearing protection as required.
What measurements are taken as part of IH Survey
Noise measurements
NAVMED 6260/2
Hazardous Noise warning decal, 8” X 10”
Posted locations of NAVMED 6260/2
1) These will be posted to the outside doors/hatches leading into a hazardous noise
area.
2) However, if a door/hatch leads to the weather deck then there will be no decal
posted on the outer surface, but rather posted to inside of that particular door/hatch.
NAVMED 6260/2A
Hazardous noise label, 2” X 2”
Posted locations of NAVMED 6260/2A
Used to label smaller, individual pieces of equipment or tools that produce
hazardous noise.
Noise Abatement
(a) Reduction of noise at the source must be explored first before implementing other
methods of hearing loss prevention.
(b) Areas and equipment that produce potentially hazardous noise should be modified
to reduce noise levels wherever it is technologically and operationally
Double Hearing protection
noise level are equal to 96 dBA or greater or 165 dBP
No hearing protection
Noise levels less than or equal to 84 dBA
single hearing protection
Noise levels equal to 85 dBA or greater but less than 96 dBA requires single hearing
protection and placement in HCP
Double hearing protection
Noise levels equal to 96 dBA or greater require double hearing protection and placement in
HCP.
Record of noise measurements shall be kept by the measuring activity for how long
50 years
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.
How many types of hearing protection
3 types
Ear Plugs (4 types)
Straightaway muffs
Circumaural Muff
Personnel Training Requirements
All personnel included in the hearing conservation program shall receive training
PRIOR to working in noise hazardous areas and annually.
