(1) You must use audiometric testing to identify hearing loss, which may indicate program deficiencies.

(2) You must take appropriate actions when deficiencies are found with your program.

A deficiency may be indicated when:

(a) Any employee experiences measurable hearing loss indicated by a standard threshold shift; or

(b) Any employee is not wearing appropriate hearing protection during an audit when auditing is used in place of baseline audiograms for short term employees (see WAC 296-817-500, Option to audiometric testing).

Note:	1. A standard threshold shift or audit deficiency does not necessarily indicate that a significant hearing loss has occurred.
	2. These criteria are intended to help identify where there may be flaws in your hearing loss prevention program that can be fixed before permanent hearing loss occurs.
	3. There are additional statistical tools and tests that may be used to improve the effectiveness of your program.
	4. Staff conducting audiometric testing and auditing may be able to suggest additional ways to improve your hearing loss prevention program and tailor it to your worksite.

(3) You must evaluate the following, at a minimum, when responding to a standard threshold shift:

(a) Employee noise exposure measurements;

(b) Noise controls in the work area;

(d) Employee training on noise and the use of hearing protection and conduct additional training as necessary.

Reference:	1. You may use the option of auditing hearing protection (see WAC 296-817-500) for employees hired or transferred to jobs with noise exposure for less than one year.
	2. You may also use audiograms provided by a third-party hearing loss prevention program in some circumstances.
	3. Details of these program options are found in WAC 296-817-500, Options to audiometric testing.
