Basic recording criterion:
In Colorado, employers must record
work-related “Standard Threshold Shift”, or STS (an
average change of 10 dB at 2000, 3000, and 4000 Hz in either
ear, compared to baseline (age-adjusted) audiometric data as
measured by a qualified examiner - either certified
occupational hearing conservationist SUPERVISED BY AN
AUDIOLOGIST OR PHYSICIAN OR A LICENSED AUDIOLOGIST. Testing must be completed in accordance with OSHA regulations. All personnel and
measurement standards by our company meet OSHA guidelines.
Reconfirmation of STS:
If the annual audiogram shows a STS, a hearing retest may be
performed within 30 days. If the retest does not confirm the
STS, then the case need not be recorded. However, if the
retest confirms the STS, then the STS if work-related, must
be recorded within 7 calendar days of retest. If a retest is
not performed, then the case (again, if work-related) must
be recorded within 37 days of test.
work-relatedness: Work-relatedness must be determined
according to specifications of section 1904.5 of the general
recordkeeping rule. If an event/exposure in the workplace
caused or contributed to the shift in hearing or
“significantly aggravated” a previously existing hearing
loss, then the STS is recordable.
Forms: OSHA has also
updated its recordkeeping forms (now OSHA Form 300, 301 and
300A). Beginning January 1, 2004, employers will be required
to record hearing loss cases in a separate column. In 2003,
employers should record cases of occupational hearing loss
as an “injury” (single event acoustic trauma) or “other
illness” (long term noise exposure), as appropriate.

State plans: Although state-run OSHA plans were allowed to
continue utilizing more stringent enforcement criteria
during 2002, all are required to adopt the final federal
rule for hearing loss recordability, effective January 1,
Certain industries are not covered under the general hearing
conservation amendment 1910.95 (construction, agriculture,
oil and gas drilling, etc.), but are included under 1904. If
such employers choose to conduct audiometric testing
programs, then the hearing loss recordability provisions of
1904.10 will apply.
