what is NAVMED 6260/2
Hazardous Noise warning decal 8 X 10
where are NAVMED 6260/2 posted
outside hatch leading into hazardous zone
inside hatch when coming from weather deck
what is the NAVMED 6260/2A
Hazardous Noise Label 2 x 2
what is the 6260/2A used for
labeling individual pieces of equipment
define noise abatement
reduction of noise at the source by modifying areas or equipment
hearing testing are conducted when for medical Surveillance
reference hearing test
monitoring hearing test
termination hearing test
noise levels less than or equal to 84
no hearing protection required
85-95 dBA requires
singe hearing protection
96 or higher dBA requires
double hearing protection
who takes noise measurements
Industrial hygienist and/or Occupational Audiologist
when is a noise measurement resurveyed
30 das after significant modifications or changes in work routine
how long is a record of noise measurements maintained by measuring activity

define a significant threshold shift (STS)
change in hearing of an average of 10dB or more at 2000, 3000, or 4000 Hz in either ear
positive STS
poorer hearing
negative sts
better hearing
procedure for negative sts
better, but could be error
retest same day
retest shows improvement= set as new reference audiogram
procedure for positive sts
retest after 14 hours
notify supervisor
retest shows no sts= return to annual monitoring
yes sts below 3000hz, screen for med issues and record on SF 600
normal finding= second test same day
2nd test negative= return to annual monitoring
2nd test positive = forward results to audiologist
when are supervisors notified in writing of STS
withing 21 days of positive STS
