WAC 296-817-50005
Conduct hearing protection audits at
least quarterly.
You must:
• Conduct audits at least quarterly to provide a
representative assessment of your workplace
– The assessment is representative if it:
▪ Covers all processes and work activities in your
business at full production levels
AND
▪ Covers all employees present on the audit day.
– If your business is mobile or involves variable
processes, auditing may need to be repeated more often than
quarterly
– Auditing does not need to be repeated more than monthly
as long as a reasonable effort is made to cover:
▪ The activities with greatest exposure
AND
▪ As many employees as possible.
• Assess exposures and hearing protection for the full
shift for each employee covered at the time of the audit.
