Administration

This written hearing conservation plan serves as a record of the details of the hearing conservation program in place at this company. We have this program in place to protect the hearing of all employees in the company. Elements of our hearing conservation program include:

• Monitoring,
• Audiometric testing program,
• Hearing protection,
• Training and information, and
• Recordkeeping.

______ has overall responsibility for coordinating safety and health programs in this company. ______ is the person having overall responsibility for the Hearing Conservation Program. ______ will review and update the program, as necessary.

Copies of the written program may be obtained from ______.

Monitoring

The monitoring program is in place to provide an ongoing means of determining employee exposure to noise and protect employees based on excessive exposure. When monitoring information indicates that any em-ployee’s exposure equals or exceeds an 8-hour time-weighted average of 85 decibels, the employee is included in the hearing conservation program.

To determine employee exposure to noise, we use the following type of calibrated equipment: ______. The company notifies all employees exposed at or above an 8-hour time-weighted average of 85 decibels of the results of the monitoring by the following method. ____________________________________.

The company provides an opportunity in the following way for affected employees or their representatives to observe any noise measurements conducted: __________________________________________.

Appropriate hearing devices are selected for employees in the Hearing Conservation Program by the following method: ___________________________________________________________________.

Monitoring is repeated whenever a change in production, process, equipment, or controls increases noise exposures to the extent that either additional employees may be exposed at or above the action level or the attenuation provided by hearing protectors being used by employees may be rendered inadequate to meet the requirements of noise reduction.

The audiometric testing program is in place and available at no cost to all affected employees to ensure that noise exposures are kept at proper levels.

Audiometric testing

The program ensures that a valid baseline audiogram is established for exposed employees within six months of their first exposure (or within one year if mobile vans are used, with employees wearing hearing protection for any period exceeding six months) by the following method: ______________________________.

Audiometric testing is repeated __________________________________________________.

The company determines if a standard threshold shift (STS) has occurred by ________________________.

If subsequent audiometric testing of an employee whose exposure to noise is less than an 8-hour TWA of 90 decibels indicates that a standard threshold shift is not persistent, the company informs the employee of the new audiometric interpretation by ______________________________________________________ and discontinues the required use of hearing protectors for that employee.

Hearing protection

The company makes hearing protectors available to all employees exposed to an 8-hour TWA of 85 decibels or greater at no cost to the employees, according to the following procedures: ________________________.

The company ensures the use of available hearing protection by all affected employees by: ____________.

The company ensures that employees have a variety of suitable protectors that attenuate (lower) employee exposure at least to an 8-hour time-weighted average of 90 decibels, or 85 decibels or lower for employees who have experienced a standard threshold shift in their hearing, according to the following method: ______.

Appropriate hearing protectors available for employees to choose from include: __________________.

The company ensures evaluation for adequacy of the hearing protection attenuation for the specific noise environments in which the protector will be used, according to specifications given in an appendix to the standard, by: ____________________________________.

The company reevaluates attenuation whenever employee noise exposures increase to the extent that current hearing protectors no longer provide adequate attenuation, and then provides more effective hearing protection, according to the following method: __________________________________________.

Training and information

______ has a hearing protection training program for all employees exposed to noise at or above an 8-hour time-weighted average of 85 decibels.

We ensure employee participation in the hearing protection training program by: __________________.

Copies of the Occupational Noise Exposure standard are available to affected employees or their representatives.We also post copies of the standard in the following location(s): __________________ ______________________________________________________________________.

Refresher training is provided ______. We ensure that the training material is updated to be consistent with changes in the protective equipment and work processes by: ______________________________________.

According to the following method: _______________________________________________, we ensure that each affected employee is informed of at least the following information:

• The effects of noise on hearing;
• The purpose of hearing protectors, the advantages, disadvantages, and attenuation of various types, and instructions on selection, fitting, use, and care; and
• The purpose of audiometric testing, and an explanation of test procedures.

We also make informational materials pertaining to the Occupational Noise Exposure standard that are supplied by OSHA available to affected employees or their representatives by: __________________.

______ maintains accurate records of:

• Employee exposure measurements by: ______________________________.
• Employee audiometric test records by: ______________________________.

The company retains noise exposure measurement records and audiometric test records as required by OSHA. These records are made available to employees, former employees, representatives designated by the individual employee, and OSHA upon request, according to the following method: _________.

Program Evaluation Checklist | Occupational Noise Exposure

Use the following NIOSH checklist to evaluate your hearing conservation program.

Training and education

Failures or deficiencies in hearing conservation programs (hearing loss prevention programs) can often be traced to inadequacies in the training and education of noise-exposed employees and those who conduct elements of the program.

1. Has training been conducted at least once a year?
2. Was the training provided by a qualified instructor?
3. Was the success of each training program evaluated?
4. Is the content revised periodically?
5. Are managers and supervisors directly involved?
6. Are posters, regulations, handouts, and employee newsletters used as supplements?
7. Are personal counseling sessions conducted for employees having problems with hearing protection devices or showing hearing threshold shifts?

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.

1. Have supervisors been provided with the knowledge required to supervise the use and care of hearing protectors by subordinates?
2. Do supervisors wear hearing protectors in appropriate areas?
3. Have supervisors been counseled when employees resist wearing protectors or fail to show up for hearing tests?
4. Are disciplinary actions enforced when employees repeatedly refuse to wear hearing protectors?

Noise measurement

For noise measurements to be useful, they need to be related to noise exposure risks or the prioritization of noise control efforts, rather than merely filed away. In addition, the results need to be communicated to the appropriate personnel, especially when follow-up actions are required.

1. Were the essential/critical noise studies performed?
2. Was the purpose of each noise study clearly stated? Have noise-exposed employees been notified of their exposures and appraised of auditory risks?
3. Are the results routinely transmitted to supervisors and other key individuals?
4. Are results entered into health/medical records of noise exposed employees?
5. Are results entered into shop folders?
6. If noise maps exist, are they used by the proper staff?
7. Are noise measurement results considered when contemplating procurement of new equipment? Modifying the facility? Relocating employees?
8. Have there been changes in areas, equipment, or processes that have altered noise exposure? Have follow-up noise measurements been conducted?
9. Are appropriate steps taken to include (or exclude) employees in the hearing loss prevention programs whose exposures have changed significantly?

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.

1. Have noise control needs been prioritized?
2. Has the cost-effectiveness of various options been addressed?
3. Are employees and supervisors appraised of plans for noise control measures? Are they consulted on various approaches?
4. Will in-house resources or outside consultants perform the work?
5. Have employees and supervisors been counseled on the operation and maintenance of noise control devices?
6. Are noise control projects monitored to ensure timely completion?
7. Has the full potential for administrative controls been evaluated? Are noisy processes conducted during shifts with fewer employees? Do employees have sound-treated lunch or break areas?

Monitoring audiometry and recordkeeping

The skills of audiometric technicians, the status of the audiometer, and the quality of audiometric test records are crucial to hearing loss prevention program success. Useful information may be ascertained from the audiometric records as well as from those who actually administer the tests.

1. Has the audiometric technician been adequately trained, certified, and recertified as necessary?
2. Do on-the-job observations of the technicians indicate that they perform a thorough and valid audiometric test, instruct and consult the employee effectively, and keep appropriate records?
3. Are records complete?
4. Are follow-up actions documented?
5. Are hearing threshold levels reasonably consistent from test to test? If not, are the reasons for inconsistencies investigated promptly?
6. Are the annual test results compared to baseline to identify the presence of an OSHA standard threshold shift?
7. Is the annual incidence of standard threshold shift greater than a few percent? If so, are problem areas pinpointed and remedial steps taken?
8. Are audiometric trends (deteriorations) being identified, both in individuals and in groups of employees? (NIOSH recommends no more than 5% of workers showing 15 dB Significant Threshold Shift, same ear, same frequency.)
9. Do records show that appropriate audiometer calibration procedures have been followed?
10. Is there documentation showing that the background sound levels in the audiometer room were low enough to permit valid testing?
11. Are the results of audiometric tests being communicated to supervisors and managers as well as to employees?
12. Has corrective action been taken if the rate of no-shows for audiometric test appointments is more than about 5%?
13. Are employees incurring STS notified in writing within at least 21 days? (NIOSH recommends immediate notification if retest shows 15 dB Significant Threshold Shift, same ear, same frequency.)

Referrals

Referrals to outside sources for consultation or treatment are sometimes in order, but they can be an expen-sive element of the hearing loss prevention program, and should not be undertaken unnecessarily.

1. Are referral procedures clearly specified?
2. Have letters of agreement between the company and consulting physicians or audiologists been executed?
3. Have mechanisms been established to ensure that employees needing evaluation or treatment actually receive the service (i.e., transportation, scheduling, reminders)?
4. Are records properly transmitted to the physician or audiologist, and back to the company?
5. If medical treatment is recommended, does the employee understand the condition requiring treatment, the recommendation, and methods of obtaining such treatment?
6. Are employees being referred unnecessarily?

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 implementers as well as noise-exposed employees.

1. Have hearing protectors been made available to all employees whose daily average noise exposures are 85 dBA or above? (NIOSH recommends requiring HPD use if noises equal or exceed 85 dBA regardless of exposure time.)
2. Are employees given the opportunity to select from a variety of appropriate protectors?
3. Are employees fitted carefully with special attention to comfort?
4. Are employees thoroughly trained, not only initially but at least once a year?
5. Are the protectors checked regularly for wear or defects, and replaced immediately if necessary?
6. If employees use disposable hearing protectors, are replacements readily available?
7. Do employees understand the appropriate hygiene requirements?
8. Have any employees developed ear infections or irritations associated with the use of hearing protectors? Are there any employees who are unable to wear these devices because of medical conditions? Have these conditions been treated promptly and successfully?
9. Have alternative types of hearing protectors been considered when problems with current devices are experienced?
10. Do employees who incur noise-induced hearing loss receive intensive counseling?
11. Are those who fit and supervise the wearing of hearing protectors competent to deal with the many problems that can occur?
12. Do workers complain that protectors interfere with their ability to do their jobs? Do they interfere with spoken instructions or warning signals? Are these complaints followed promptly with counseling, noise control, or other measures?
13. Are employees encouraged to take their hearing protectors home if they engage in noisy non-occupational activities?
14. Are new types of or potentially more effective protectors considered as they become available?
15. Is the effectiveness of the hearing protector program evaluated regularly?
16. Have at-the-ear protection levels been evaluated to ensure that either over or under protection has been adequately balanced according to the anticipated ambient noise levels?
17. Is each hearing protector user required to demonstrate that he or she understands how to use and care for the protector? The results documented?

Administrative

Keeping organized and current on administrative matters will help the program run smoothly.

1. Have there been any changes in federal or state regulations? Have hearing loss prevention pro-gram’s policies been modified to reflect these changes?
2. Are copies of company policies and guidelines regarding the hearing loss prevention program available in the offices that support the various program elements? Are those who implement the program elements aware of these policies? Do they comply?
3. Are necessary materials and supplies being ordered with a minimum of delay?
4. Are procurement officers overriding the hearing loss prevention program implementer’s requests for specific hearing protectors or other hearing loss prevention equipment? If so, have corrective steps been taken?
5. Is the performance of key personnel evaluated periodically? If such performance is found to be less than acceptable, are steps taken to correct the situation?
6. Safety: Has the failure to hear warning shouts or alarms been tied to any accidents or injuries? If so, have remedial steps been taken?
