The publication covers noise assessment, hazardous noise labeling, engineering controls, hearing protection, training, audiograms, reporting systems, and program evaluations. It requires annual hearing preservation training and hearing tests, command self-assessments, and tracking of hearing readiness.
Applies to: This Order provides policy to preserve the hearing readiness of Marines, assigned Sailors and hazardous noise-exposed civilian personnel.
The following personnel will be enrolled in the HCP: (1) All active duty and reserve Marines. (2) All active duty and reserve Sailors assigned with or supporting USMC forces. (3) All civilian personnel occupationally exposed to hazardous noise. (paragraph 4)
All Marine Corps commands will conduct an annual self-assessment of their HCP using Appendix D. (paragraph 4)
Engineering controls will be the primary means of eliminating or reducing personnel exposure to hazardous SPLs. (paragraph 6)
COs and OICs will ensure a hearing readiness status at these benchmarks: (1) 100 percent of Marines, Sailors and at-risk civilian personnel have reference (baseline) audiograms. (2) 85 percent of annual or periodic audiograms are performed within one month of previous annual or periodic audiogram. (3) 100 percent of active duty personnel leaving the service and civilian personnel no longer exposed to hazardous noise receive termination audiograms. (paragraph 6)
MRRS or equivalent DITPR-DON approved system such as ESAMS, WESS or other appropriate tracking tools must be used to document hearing readiness.
