184.108.40.206 Whenever an employee is occupationally exposed to noise equal to or exceeding the NASA action level of 82 dBA Time-Weighted Average (TWA) for 30 days or more per year or can be expected to be exposed to 85 dBA TWA for any one day, Centers shall administer a continuing, effective HCP in conformance with the requirements of this section with all the affected employees included in the program. Exposures shall be computed without regard to any attenuation provided by the use of personal protective equipment.
220.127.116.11 NASA's allowable noise exposure limit is the equivalent to an 85 dBA, 8-hour TWA exposure using a 3 dB exchange rate as shown in Table 1 below.
|Table 1 |
Noise Exposure Limits
|Exposure level (dBA)||Hours||Minutes||Seconds|
a. Table 1 contains noise exposure levels and durations that are equivalent to this limit as calculated by the following formula where L stands for exposure level and T for duration: T (min) = 480/2 (L-85)/3;
b. Exposures exceeding the equivalent exposures in Table 1 shall be controlled, reduced, or eliminated through a hierarchical combination of engineering controls, administrative controls, and hearing protection devices;
c. Noise dose shall include all impact/impulse noise measured up to and including 140 dB peak; and
d. The action level is 82 dBA, 8 hour TWA.

f. Be individualized to meet Center-specific needs, configuration, and other relevant factors;
g. Contain provisions for a documented waiver process that accommodates specialized research project items or flight hardware.
22.214.171.124 Engineering Controls shall:
a. Be the first and primary means of controlling hazardous noise. The feasibility and cost of engineering controls may be considered when making decisions about these controls;
b. Attempt to reduce noise emissions (measured at operator position or equivalent) to below 85 dBA; and
c. Be reviewed to assess the adequacy of precautions that are planned and/or undertaken to control noise exposures.
126.96.36.199 Engineering projects, drawings, and operational plans, including noise control measures, shall be coordinated with affected management organizations and occupational health personnel in the early stages of the design and/or planning process and prior to contract award and/or authority to proceed.
188.8.131.52 Organizations responsible for introducing changes to facilities, operations, or procedures shall notify occupational health personnel of:
a. Any changes in operations or equipment that increases noise levels; and
b. Any new, uncontrolled, or previously unidentified areas, operations, or equipment that may produce hazardous noise or may not comply with the requirements of this section.
184.108.40.206 If engineering controls fail to reduce sound levels within the requirements specified in this section, administrative controls shall be utilized. Examples of administrative controls include access restrictions and time limitations in the hazardous noise area. Specific requirements for administrative controls include:
a. Maximizing the distance between the employee and the hazardous noise source to the extent practical; and
b. Identifying hazardous noise areas according to the following criteria:
(1) Areas determined to be hazardous noise areas shall be identified by posting with signs that conform to 29 CFR 1910.145, Specifications for accident prevention signs and tags requirements.
(2) Signs shall clearly indicate the presence of hazardous noise and state the requirement to wear hearing protection. The signs shall be posted at the entrance(s) to or the periphery of hazardous noise area(s).
(3) Decals or placards with similar statements shall be affixed to power tools and machines that produce hazardous noise levels, and caution signs shall be posted in areas where hazardous noise-producing tools and machines are used.
220.127.116.11 If both engineering and administrative controls fail to reduce sound levels to 85 dBA, 8-hour TWA or below, personal hearing protection shall be used to bring exposures to acceptable levels in accordance with the following:
a. All personnel who enter designated areas or who perform tasks where exposure to noise is greater than or equal to 82 dBA, regardless of the duration of exposure, shall be provided with personal hearing protection;

c. Earplugs shall be for the exclusive use of each employee and shall not be traded or shared;
d. Hearing Protection Devices (HPDs) shall attenuate employee noise exposure to an 8-hour, TWA of 85 dBA or less. For those employees with a Standard Threshold Shift (STS), HPDs shall attenuate exposure to an 8-hour, TWA of 82 dBA or less. HPD attenuation shall be determined by one of the following methods:
(1) The published Noise Reduction Rating (NRR) value may be used in accordance with the guidance in this section. When using the NRR of a hearing protector to predict protected exposure levels, the following de-rating criteria shall apply for all types of HPDs, where "NRR" is the manufacturer's Noise Reduction Rating. Required NRR = [(LA - 85) x 2] + 7, where LA is the measured ambient sound level to which the employee is exposed.
(2) Where it is not possible to provide the calculated value of Required NRR in (i) above, the Required NRR may be calculated using the employee's unprotected TWA exposure in place of LA. Required NRR = [(TWA - 85) x 2] + 7, where TWA is the employee's unprotected TWA exposure level. TWA values that are used in the calculation of required NRR shall reflect actual hours worked and all contributions to the employee's exposure.
(3) Real-world attenuation of a particular employee's field-fit HPD may be determined experimentally using a commercial fit-check system or other published method, such as those described in ANSI S12.68. Protected exposures shall be calculated from experimentally-derived attenuation data in accordance with the guidance provided by the particular method chosen.
e. The adequacy of HPD attenuation shall be re-evaluated whenever employee noise exposures increase;
f. Special hearing-protective equipment, such as sound-suppression or noise-cancellation communication headsets, shall be regularly inspected if they are used in hazardous noise areas;
g. Sound-suppression and noise-cancellation headsets that have been damaged, altered, or modified in any way that affect the attenuation characteristics shall not be used; and

18.104.22.168 Noisy areas shall be surveyed to determine if they are hazardous noise areas in accordance with the following requirements:
a. Measurement of potentially hazardous sound levels shall be conducted when any information, observation, or calculation indicates that an employee may be exposed to noise at or above the action level. This includes, but is not limited to, times where there is a need to document representative noise exposures, where employees complain of excessive noise, or where it is difficult to understand a normal conversation when the speaker and listener face each other at a distance of 3 feet;
b. Noise surveys shall also be conducted whenever any changes to facilities, equipment, work practices, procedures, or noise-control measures alter potential noise exposures. A review of hazardous noise sources and controls, employee exposures, and work practices and procedures shall be conducted for changed conditions whenever an employee experiences an STS;
c. In determining TWA exposures, all continuous, intermittent, and impulsive sound levels, from 80 dBA to 140 dBA, shall be integrated into the noise measurements;
d. Octave band analysis shall be conducted, as necessary, to establish the characteristics of the noise source and to help determine appropriate abatement techniques;
e. When a noise survey is performed, it shall determine the presence of compounding hearing-related circumstances present in the environment (e.g., certain solvents, heavy metals, carbon monoxide, heat, and vibration) to ensure proper mitigation;
f. Exposure monitoring shall be conducted when a noise survey shows that any employee or group of employees may be exposed to noise at or above 82 dBA, 8-hour TWA. The purpose of such monitoring is to determine the noise dose of the exposed employee and the representative exposure of similarly exposed employees and to determine appropriate noise abatement techniques;
g. All noise surveys and personal noise dosimetry monitoring shall be conducted in accordance with 29 CFR 1910.95 requirements, unless otherwise specified in this section;
h. Operational plans shall be reviewed to assess the adequacy of precautions that are planned and/or implemented to control noise exposures;

184.108.40.206 Medical surveillance shall be provided to all employees enrolled in an HCP in accordance with the following requirements:
a. Employees receiving medical surveillance shall undergo a baseline audiometric examination before beginning work assignments in hazardous noise areas;
b. If it is not possible to obtain the baseline prior to noise assignment, then employees shall undergo a baseline audiometric examination within 30 days of initial exposure to hazardous noise. During this 30-day period, employees shall wear personal HPDs, which reduce their exposure to 82 dBA TWA or below. When it is discovered that personnel have already been assigned to a position that may expose them to hazardous noise but have not yet had an audiometric examination, audiometry shall be conducted within 30 days of the discovery, and employees shall wear personal hearing protection that reduces their exposure to 82 dBA TWA or below;
c. Audiometric examinations shall include an audiogram, an otoscopic examination by an audiologist, physician, or CAOHC Certified Occupational Hearing Conservationist to determine any existing medical pathology of the ear, and an update to their medical history (occupational and personal) to document past noise exposure and other otopathological factors;
d. The employee shall have no apparent or suspected ear, nose, or throat problems that might compromise the validity of the audiogram. When an employee has an acute disease that may compromise the validity of the test, the audiogram shall be delayed until the condition has abated;
e. The exposure history taken at the time of the audiometric examination shall include ototoxic medications and exposure to ototoxic substances;
f. Personnel suffering from acute diseases of the ear shall not be placed in hazardous noise areas until the condition has abated, particularly if such diseases preclude the wearing of hearing protectors;
g. Centers shall take all possible measures to assure that employees who have participated in the HCP medical surveillance program receive a final audiometric examination prior to termination of employment, transfer to duties not involving noise exposures, transfer to another installation, or retirement. An annual audiogram, if completed within six (6) months of the termination, transfer, or retirement date, may be substituted for the final audiogram; and
h. When employees at a Center retain their "work role position" but change employers due to contract award to a new employer, all medical records applicable to hearing conservation shall follow them to their new employer, including their current baseline threshold.
220.127.116.11 Audiometric testing shall be performed upon initial assignment, and annually thereafter, in accordance with 29 CFR 1910.95, Sections (g) and (h) and as follows:

b. Personnel who conduct audiometric testing shall be familiar with the provisions of this section;
c. All baseline audiograms and confirmation audiograms following the identification of a STS shall be preceded by a period of at least 14 hours during which there is no known exposure to noise above 82 dBA TWA, on or off the job. Hearing protectors that lower workplace noise to the equivalent of 82 dBA TWA, using the appropriate noise-reduction rating, may be used to conform to this requirement;
d. An STS shall be logged as an OSHA-recordable event in accordance with 29 CFR 1904.10 if the answers to ALL of the questions below are "yes:"
(1) Did an annual age-corrected audiogram reveal a STS (10 dB shift or greater, averaging 2k, 3k, and 4k Hz) relative to the baseline audiogram in one or both ears? (Age correction permitted.)
(2) Is the employee's uncorrected hearing threshold level (averaging 2k, 3k, and 4k Hz) 25 dB or greater above audiometric zero in the same ear as the STS? (Age correction NOT permitted.)
(3) Is the STS work-related as determined by physician or other licensed health care professional, in consultation with the employer? This determination must be made in accordance with CFR 1904.5.
e. If during any medical evaluation or audiometric examination, the employee is identified as potentially unable to perform the job safely or has a hearing profile equal to or worse than that listed in Table 2 below, the employee and employer shall receive a written notification of the requirement to perform an Ability and Risk Evaluation. The written notification shall include results of the medical and work history with special emphasis on the association of any health conditions that may impair ability to safely perform the work expected in the position held (e.g., hear commands or signals) or the ability to wear appropriate personal hearing protection equipment in a hazardous noise area.
|Hearing Threshold Level (dB)||25||25||25||35||45||45|
18.104.22.168 The requirements for handling threshold shifts are as follows:
a. The STS may be computed using the age corrections described in OSHA 29 CFR 1910.95, Appendix F;
b. Each employee's annual audiogram shall be compared to his/her baseline audiogram to determine if the audiogram is valid and to determine if an STS has occurred;
c. The baseline of each ear shall be separately tracked;
d. A physician, audiologist, or CAOHC-certified Occupational Hearing Conservationist shall perform the hearing test and the comparison;
e. If an STS is identified and a confirmation audiogram is not performed within 30 days, the STS shall become a confirmed STS by default;
f. If the identified STS is followed by a confirmation audiogram and the confirmation audiogram does not confirm the STS, this second audiogram replaces the first one that suggested the STS;
g. If the identified STS is followed by a positive confirmation audiogram, the better of the two shall become the confirmed STS;
h. An audiologist or physician with hearing conservation experience shall review problem audiograms, including those showing an STS (either by confirmation within 30 days or by default) and shall determine whether there is a need for further evaluation.
i. When further evaluation is warranted, the employee shall be referred to an otolaryngologist or other qualified physician, or to an audiologist for further medical evaluation. See Section 4.8.3.l7, Referrals; and
j. A new baseline reference audiogram shall replace the original or previous baseline audiogram (in separate ears and not both ears, unless both ears meet criteria listed below) when:
(1) The reviewer determines that an STS is persistent on a retest (conducted no sooner than six (6) months later). The baseline shall be revised to the lower (more sensitive) value for the average. Employees assigned a new baseline audiogram, as a result of an STS, shall receive an audiometric re-evaluation six (6) months after this assignment to determine if a further STS has occurred.
(2) A "significant improvement" is shown if the average of thresholds at 2000, 3000, and 4000 Hz for either ear shows an improvement of 5 dB or more from the baseline and the improvement is persistent in the next test. The baseline shall be revised to the lower (more sensitive) value for the average. Age corrections shall not be used when determining "improvement."
(3) An audiologist or physician determines that reasons exist for not revising an employee's baseline audiogram. In such cases, the audiologist or physician must document the reasons for not revising the baseline.
k. The employee, employer, and environmental health staff shall be notified of an STS in writing within 21 days of the determination of the STS;
l. If the employee's uncorrected hearing threshold level, without age correction (averaging 2k, 3k, and 4k Hz) is 25 dB or greater above audiometric zero in the same ear as the STS, a work-relatedness determination shall be made for purposes of OSHA recordability. Based on the best available information, a physician or other licensed health care professional, in consultation with the employer, shall determine, in accordance with CFR 1904.5, whether the noise-induced STS is work-related;
m. Unless a physician has determined that the STS is not work-related, the following actions shall be taken:
(1) The employee's management and responsible safety and health office shall be notified of the occurrence of an STS or other work-related hearing loss.
(2) The work-related hearing loss shall be relayed to the Center's mishap reporting system.
(3) The employee shall be notified and examined by a physician or an audiologist for proper HPD fit.
(4) HPDs shall be re-evaluated for effectiveness, and the employee shall be refitted as necessary with HPDs offering a greater sound attenuation.
(5) The employee shall be trained or retrained on the hazardous effects of noise and the need to use hearing protection.
(6) The work environment(s) shall be investigated to determine if work practices or changes in equipment or procedures have increased the noise hazard. Abatement actions shall be instituted, as necessary, with engineering controls employed first to reduce the potential for exposure to the action level.
(7) Any administrative and work practices being utilized to reduce noise exposures shall be re-evaluated for effectiveness.
n. When an OSHA-recordable STS has occurred, the employer shall record the condition as a hearing loss on the OSHA 300 Log and maintain the record in accordance with 29 CFR 1904, Recording and Reporting Occupational Injuries and Illnesses;
o. The Medical Director shall determine if reassignment to work in a low noise area is indicated to prevent further hearing impairment and shall advise the employer accordingly;
p. The employer shall have ultimate authority and responsibility for employee reassignment; and
q. Where the same employee experiences any subsequent work-related STS as a result of occupational noise exposure, the work environment(s) shall be re-evaluated. If the employee continues to work in the hazardous noise area(s), engineering and/or administrative controls shall be employed that reduce that employee's noise exposure to no more than 50 percent of what was previously allowed for that employee.
22.214.171.124 Employees shall be referred to an otolaryngologist or other physician knowledgeable in hearing conservation or to an audiologist based on the following criteria:
a. Where further medical testing or referrals are needed, the employee shall be notified of the reason for the testing or need for referral;
b. When the examining physician refers an employee to a specialist, communication of relevant medical data shall be provided to the specialist; and
c. The following criteria are based upon the American Academy of Otolaryngology-Head and Neck Surgery referral criteria and shall be used for referral to a qualified physician or otolaryngologist for more comprehensive testing and/or treatment.

4.9.3 Process Description
220.127.116.11 Each Center shall have a written ergonomics program that includes at least the following elements:
a. Management support and employee participation;
b. Worksite analysis;
c. Job analysis;
d. Medical management;
e. Training; and
f. Program evaluation.
18.104.22.168 Management support of the ergonomics program shall be demonstrated at a minimum by approving a Center ergonomic policy. This starts at program/project initiation with the incorporation of ergonomic principles and requirements in procurement of furniture and equipment. Employees (and their designated representatives) shall have ways to report "MSD signs and symptoms," obtain responses to reports, and participate in developing, implementing, and evaluating each element of the program. Policies or practices shall not discourage employees from participating in the program or from reporting MSD's signs or symptoms. A method for employees to report MSD signs and symptoms and to get prompt responses shall be established. Employee reports of MSD signs and symptoms shall be evaluated to determine whether a MSD has occurred. Information to employees shall be periodically provided that explains how to identify and report MSD signs and symptoms.
22.214.171.124 A worksite analysis shall be performed where existing hazards and conditions exist, and where operations or areas with the potential to create hazards exist. This includes scrutiny and tracking of injury and illness records to identify patterns of traumas or strains that may indicate the development of MSD's. Whenever new ergonomic hazards are introduced to operations, a worksite analysis shall be performed.
126.96.36.199 Operations with significant ergonomic risk factors present shall be analyzed to fully define the ergonomic risk factors that result in MSD hazards. The ergonomic hazards must be eliminated, reduced to the extent feasible, or materially reduced using an incremental abatement process.
188.8.131.52 A medical intervention/management system shall be designed and implemented to eliminate or reduce the risk of development of MSD's through early identification and treatment by qualified medical providers. Concerted efforts shall be made to return employees to work as soon as possible.
184.108.40.206 Employees shall be provided proper ergonomic training to make employees aware of the ergonomics program, MSD hazards, and methods for eliminating MSD hazards.
220.127.116.11 The Ergonomic Program shall be re-evaluated periodically and identified deficiencies corrected. Metrics that document the efficacy of the ergonomics program shall be maintained and used to improve the program and to reduce MSD risks.
18.104.22.168 NASA recognizes the negative impact poor IAQ can have in the workplace on injuries, illnesses, and adverse health symptoms affecting employee productivity, morale, and absenteeism. This requirement establishes minimum standards for all NASA Center IAQ programs with regard to complaint investigation, IAQ testing, communication of IAQ information to employees, mold remediation, recordkeeping, and general requirements.
22.214.171.124 The CHMO shall establish and maintain an IAQ policy that is reflective of Federal guidance, provide coordination and communications with the NASA Centers, and provide technical and subject matter expertise.
126.96.36.199 The CHMO shall provide IAQ program oversight and assess compliance with this policy.
188.8.131.52 Centers shall ensure that they have a written IAQ program that is designed to ensure all indoor environments are safe and free from recognized hazards for human occupancy.
184.108.40.206 Centers shall ensure that their IAQ programs include provisions for:
a. Investigating IAQ complaints, offering technical guidance and support on minimizing the impact of constructions, renovation, and maintenance activities on IAQ, and recommending corrective actions to resolve all IAQ problems;
b. Evaluating the medical condition of employees who are potentially affected by exposure to indoor air contaminants;
c. Ensuring building heating, ventilation, and air-conditioning (HVAC) system designs and modifications meet recommended standards, including the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) guidelines for relative humidity and temperature, and do not adversely affect local exhaust ventilation systems used to control hazardous materials;
d. Providing housekeeping services that minimize dust accumulation and food wastes and maintain carpets in a manner which is sufficient to minimize the likelihood of IAQ complaints; and
e. Ensuring indoor work areas are free from contaminants (i.e., visible mold, pesticides, ozone from copiers, open chemical containers, outdoor sources, etc.) that contribute to IAQ problems.
4.10.3 Process Description
220.127.116.11 General IAQ investigations shall involve the cooperation of several organizations at a Center, including the affected individuals, industrial hygiene (IH), occupational medicine, building managers, janitorial staff, maintenance, and operations staff.
18.104.22.168 IAQ investigations shall follow four basic steps (these are not necessarily distinct stages and some may be intermixed depending on the situation and discretion of the investigator):
a. Identification of an IAQ concern;
