Records quite often get the least attention of any of the hearing loss prevention
program's components. But audiometric comparisons, reports of hearing protector use, and
the analysis of hazardous exposure measurements all involve the keeping of records.
Unfortunately, records are often kept poorly because there is no organized system in
place, and in many cases, those responsible for maintaining the records do not understand
their value. People tend to assume that if they merely place records in a file or enter
them into a computer, adequate record keeping procedures are being followed.
Many companies have found that their record keeping system was inadequate at the moment
accurate information was most needed. This has often occurred during the processing of
compensation claims. Problems can be avoided by implementing an effective record keeping
system, in which: 1) management encourages that the system be kept active and accessible,
2) hearing loss prevention program implementors make sure that all of the information
entered is accurate and complete, and 3) employees validate the information.
Hearing loss prevention program records should include all items for each phase of the
program: 1) hearing loss prevention audit, 2) monitoring hearing hazards, 3) engineering
and administrative controls, 4) audiometric evaluation, 5) personal hearing protective
devices, 6) education and motivation, and 7) program evaluation. Each phase generates its
own form of records, and the information from the various records must be considered in
order to evaluate the effectiveness of the hearing loss prevention program.
OSHA's record keeping requirements can be found in items no. 45-49 of Appendix A in
this document. For more information on this subject, readers may consult the recommended
readings at the end of this section, as well as the checklists in Appendix B. The reader
is also referred to the chapter on Emerging Trends and Technologies for a discussion of
the use of optical card technologies to store and retrieve hearing loss prevention program
Management should make available the facilities to store records and should provide
sufficient resources to process them quickly and accurately. The forms or computer format
used to gather information are the foundation of a good record keeping system. These forms
should be designed so that necessary actions are triggered and then documented. If a
company does not have the available resources to design a hearing loss prevention record
keeping system compatible with the general safety and health record system, the company
should turn to consultants for assistance.
Because hearing loss prevention program records can be complex, management should see
that program implementors are fully trained in the record keeping system and its function.
There should be working copies of records as well as archived copies. If an outside
contractor keeps the records, a method should be established to ensure that original
records are accurate, and are returned and entered into the company's files in a timely
Hearing loss prevention records are medical records and, as such, deserve the same
level of integrity and confidentiality as other medical records. The company needs to make
sure that these records are accessible only to program implementors, affected employees or
their designated representatives, and government inspectors. Increasingly, companies
maintain all of their employee health and safety records in a computer system. The use of
computers supports easy access and storage of data, provides for automatic triggering of
actions based on the data contained in the records, and generates hard copies to be
maintained as archives. Prudent managers will see that original copies of records
pertaining to individual audiometry and hazard exposure monitoring are retained in
personal medical or industrial hygiene folders.
The records should be made available at the time of audiometric testing. Having the
audiogram available will allow an instantaneous check of the new audiogram with the others
on record so that checks for threshold shift can be made and so that the reliability of
the new audiogram can be assessed. Having information about hearing hazard exposure,
hearing protector use, and related information available will allow the tester to make an
accurate and timely report to the employee of the outcome of the evaluation as well as
conduct the one-on-one training that is so important to hearing loss prevention program
Program Implementor Responsibilities
In most cases, hearing loss prevention program implementors will use a records system
and associated forms that were developed by someone else, and must adapt their own
procedures accordingly. The hearing loss prevention program implementor or operator must
make sure that all information entered in the records is accurate, complete, legible,
verifiable, and stated clearly so that the information does not need to be interpreted. If
the operator discovers, while reviewing a record, that an employee's noise exposure level
is not known, the measurements should be obtained and entered in the record. The same
applies to other kinds of information. Also, there should be no blanks left in the form,
since it is not possible to know whether a question did not apply or was overlooked. When
blanks appear, they should be filled in or marked with NA for "not applicable"
or INA for "information not available." Additional abbreviations should be
avoided unless their meanings are clearly stated on the form in which they appear.
Finally, original copies should always be available in an archive.
While management may provide the record keeping system and the necessary resources, the
program implementors must ensure that the system works. The most important attributes of
an effective record keeping system are standardization, maintenance, integration, and
documentation. Standardization ensures commonality and consistency of data and format.
Maintenance keeps records current and accurate. Integration of the recorded information
allows the program implementor to assess the impact of the program on employees' hearing.
Documentation of hearing loss prevention program elements permits analysis of long-range
implications since cause-effect relationships associated with hazardous exposure levels
only become evident over time.
Program implementors may wish to consider the following rule of thumb regarding how
long records should be kept: Keep all records until you leave - then let the next person
decide how long to keep the records. More practically, records should be kept for the
length of employment plus 30 years, just as is standard practice with medical records.
Thus, it is important for the program implementor to have resources for adequate records
storage facilities be they computer-based or in hard copies.
Employee hearing loss prevention records should be available and accessible, especially
at the time of regularly scheduled hearing tests. This is the ideal time for employees to
check on the status of their hearing, and to pass along their comments on the hearing loss
prevention program. Workers have a vested interest in the accuracy, validity, and
accessibility of their hearing loss prevention and other medical records. Once they have
been properly counseled, they should sign each audiogram to identify it as their own, and
to signify that they are aware of any changes in hearing. They should also verify the
accuracy of their medical history, any non-occupational noise and chemical-exposure
history, and past and current personal or work-related information.
