Hearing Conservation Program
Caliber Construction Alaska LLC Hearing Conservation Program
The Program Administrator for Caliber Construction Alaska will be Nicholas Cherry.
Administrative responsibilities include: Coordination of and supervision of noise exposure monitoring.
- Identification of employees to be included in the HCP.
- Coordination and supervision of audiometric testing program.
- Supervision of hearing protector selection.
- Development of policies relating to the use of hearing protectors.
- Supervision of employee training.
- Coordination and supervision of record keeping.
- Evaluation of overall program.
While noise control systems are being evaluated and installed or where it is not feasible to decrease noise exposures to acceptable levels, it is required to establish a hearing conservation program. The required elements of the program are:
Monitoring
Noise exposure levels must be measured wherever they may reasonably be expected to be above an eight-hour time weighted average of 85 dBA.
For our Company, the following operations are known to be loud and until measured, assume levels are in excess of 85 dBA:
Jackhammer Operations
Sawing Operations
Compacting Operations
Monitoring will be conducted by Caliber Construction Alaska. Where possible, check with the main office to determine if historic data was conducted and can be used for specific operations.
Employee will have the opportunity to observe the monitoring in a manner that does not disrupt the work flow.
Noise Controls
Noise controls must be evaluated and implemented wherever employee exposures are at or above an eight-hour time weighted average of 90 dBA.
Remember: We expect superintendents/foremen to utilize controls where possible:
- Block the noise by building temporary barriers of plywood or other noise reducing material to block or absorb the noise from reaching the workers.
- Move equipment further away with the use of proper extension cords, additional welding leads, and air hoses.
- Reduce the noise by buying/renting/leasing equipment which is quieter and using appropriate hearing protection devices. Call supplier for alternatives.
Audiometric Testing Program
All employees with an eight-hour time weighted exposure of 85 dBA or above must be included in an audiometric testing program. A baseline audiogram must be established within the first six months of exposure and annual testing and evaluation must be done.
The Program Administrator will ensure that all affected employees participate in the company Audiogram Program which includes baseline testing as soon after orientation as possible but within 6 months of first exposure. Annual audiograms will be taken to compare to baselines and assess whether employee(s) have experienced measurable hearing loss. Exposure to noise will be minimized for 14 hours prior to obtaining this baseline exam and subsequent annual tests.
Annual Audiograms will be performed by Caliber Construction Alaska and review all audiogram and refer employees with questionable audiograms to Caliber Construction Alaska. If a standard threshold shift (an average shift in either ear of 10 dB or more at 2000, 3000, or 4000 Hz) is identified:
- The employee will be notified of the threshold shift within 21 days of this determination;
- The employee will be informed of the need for further evaluation if a medical problem is suspected;
- The use of hearing protection will continue to be enforced;
- The employee will be refitted and retrained in the use of hearing protection.
Hearing Protection
The employer must provide hearing protection for all employees that have an eight-hour time weighted exposure of 85 dBA or above, who have any continuous exposure at or above 115 dBA, or who have an exposure to any impulse noise levels above 140 dB.
Our Company will provide Hearing Protection (HP). If HP has been identified by the Company to be worn, employees are required to wear that HP during operations where noise levels are in excess. - see below.
Excavation and Backfill
Demolition
Grading
Dozer Operations
Excavator Operations
Loader Operations
Jackhammer Operations
Sawing Operations
Compacting Operations
Those operations identified in Section 1 of this program will require Hearing Protection until determined through monitoring that HP is no longer warranted.
The job positions for our company which require hearing protection are:
Laborer
Operator
Grade Checker
Training
Employers must provide annual training to all employees exposed to noise at or above an eight-hour time weighted average of 85 dBA. Training must include the following items:
- the effects of noise on hearing
- information on hearing protectors and their use,
- information on audiometric testing and its purpose, and
- the employees right to access to records.
The employer must maintain a written description of the training program.
The attached training document will be included as part of this written program.
Record keeping
Audiometric test records need to contain the following information:
- name and job classification of employee,
- date of audiogram,
- examiner’s name,
- date of last calibration of the audiometer,
- employees most recent noise exposure assessment, and
- employer (or his designated testing agent) shall maintain accurate records of the measurements of the background sound pressure levels in the audiometric test rooms.
Records Retention:
-
- Audiometric test records will be retained for the duration of the affected workers employment.
- Noise Exposure monitoring records are required to be kept two (2) years.
- All records will be provided to employee upon their request.

Hearing Conservation Checklist
Supervisor Involvement
Data indicate that employees who refuse to wear hearing protectors or who fail to show up for hearing tests frequently work for supervisors who are not totally committed to the hearing loss prevention programs.
Engineering and Administrative Controls
Controlling noise by engineering and administrative methods is often the most effective means of reducing or eliminating the hazard. In some cases, engineering controls will remove requirements for other components of the program, such as audiometric testing and the use of hearing protectors.
Hearing Protection Devices
When noise control measures are infeasible, or until such time as they are installed, hearing protection devices are the only way to prevent hazardous levels of noise from damaging the inner ear. Making sure that these devices are worn effectively requires continuous attention on the part of supervisors and program implementors as well as noise-exposed employees.
Administrative
Keeping organized and current on administrative matters will help the program run smoothly.
