184.108.40.206 Unless specified elsewhere in this chapter, NASA Centers shall utilize OSHA Permissible Exposure Limits (PEL's), Threshold Limit Values (TLV's) issued by the American Conference of Governmental Industrial Hygienists (ACGIH) or specific NASA Health Standards issued by the OCHMO, whichever is more protective or whichever is selected by a competent person (See Appendix A).
Note: While the OSHA PEL's carry the weight of law, the majority of these regulations were adopted in 1970 from 1968 consensus values and most often do not reflect current scientific data. Additionally, there are currently only PEL's established for approximately 400 chemicals, which is a relatively small percentage of the thousands of chemicals that exist. For these reasons, NASA adopts the use of OEL's as a necessary and prudent practice.
220.127.116.11 The OCHMO shall provide guidance and advice to NASA Centers on OELs.
18.104.22.168 The Director of Health and Medical Systems shall ensure Center OEL policy and programs are assessed for efficacy through regular, periodic reviews.
22.214.171.124 At a minimum, Centers shall follow the OEL's required by law, recommended and established by acknowledged authorities, and those developed specifically by NASA and shall apply whichever is more protective in the judgment of a competent person, such as a Certified Industrial Hygienist (CIH).
126.96.36.199 Centers shall be responsible for monitoring the workplace and workforce, selecting the most appropriate and protective OEL's for the work being performed, and ensuring people with appropriate training implement OEL's.
188.8.131.52 Centers shall be responsible for developing OEL's in the absence of an existing OEL for a specific chemical.
4.2.3 Process Description
184.108.40.206 In the absence of a specific PEL, TLV, or NASA Standard, other sources of OEL's shall be utilized. These include the following: (1) The National Institute for Occupational Safety & Health's (NIOSH) Recommended Exposure Limits (REL's); (2) The American National Standards Institute (ANSI) Standards; (3) The National Academy of Science Recommendations; (4) The American Industrial Hygiene Association (AIHA) Workplace Environmental Exposure Levels (WEELs); (5) The Environmental Protection Agency (EPA) Recommendations; (6) The Deutsche Forschungsgemeinschaft (German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area) Maximum Allowable Concentrations; (7) The British Health & Safety Commission and Health & Safety Executive Occupational Exposure Limits and (8) Chemical manufacturers' recommended exposure values.
NOTE: When no established OEL exists for a specific chemical, a working OEL should be established by a competent person based on a thorough examination of the data available for that chemical and by following established industrial hygiene exposure limit setting guidelines. The process of establishing a working OEL should take into account chemical analogy, animal experimentation and extrapolation, and human experience and epidemiological data. In lieu of establishing a working OEL, Centers may take the approach of using control banding until an OEL is set by one of the organizations listed above. If Centers need assistance in determining OEL's, the Agency will pursue individual requests with the appropriate Federal agency or standard-setting organization.
220.127.116.11 Document the rationale used in establishing an OEL. The rationale should consider, summarize, and weigh the importance of all data. Additionally, experience and professional judgment shall be applied to weigh all information and apply an appropriate safety factor, based on the strength of the available data, before an OEL is established.
18.104.22.168 All of the available data used to establish the OEL shall be thoroughly documented.
22.214.171.124 Centers shall notify the OCHMO of all newly established OELs.
126.96.36.199 NASA Centers shall use a systematic and comprehensive approach to exposure assessment to anticipate, recognize, evaluate, and control health hazards in the workplace to effectively and proactively manage all EH programs.
188.8.131.52 The OCHMO shall provide guidance and advice to NASA Centers on occupational exposure assessment and management.
184.108.40.206 The Director of Health and Medical Systems shall ensure Center occupational exposure assessment and management policy and programs are assessed for efficacy through regular, periodic reviews.
220.127.116.11 Centers shall employ a systematic and comprehensive approach to exposure assessment, establishing and implementing effective exposure assessment and management programs to anticipate, recognize, evaluate, and control health hazards in the workplace.
4.3.3 Process Description
18.104.22.168 EH programs shall establish a written Occupational Exposure Assessment and Management Program whose purpose is to collect and organize available information on the workplace; the workforce; chemical, physical, and biological agents; existing exposure controls; historical exposure data; biological monitoring data; and any other available source of information such as OEL's.
22.214.171.124 The written program shall include program goals and objectives and shall include an initial comprehensive exposure assessment, which shall be maintained current.
126.96.36.199 The outcome of this exposure assessment effort shall be a complete summary of available, essential information on workers, tasks, chemical, physical and biological agents, potential exposures (factoring in frequency and duration) and potential health effects.
188.8.131.52 Center EH programs shall create similar exposure groups (SEG's) and define exposure profiles for all identified exposure groups. The exception to this requirement would be research and test operations, which do not lend themselves to having similar exposures.
184.108.40.206 A determination shall be made about the acceptability, unacceptability, or uncertainty of the exposure profile defined for each SEG. Uncertain exposures shall lead to further information gathering. Unacceptable exposures shall lead to control of the exposure. Acceptable exposures shall lead to a periodic programmed reassessment based on risk.
220.127.116.11 Exposure groups with unacceptable exposures shall be prioritized and a strategy developed for exposure control.
18.104.22.168 OM clinics shall be notified regarding action level and unacceptable exposures for medical surveillance purposes and to identify SEGs.
22.214.171.124 Exposure assessment programs shall have a component that involves continual information gathering for the purpose of setting priorities on exposure groups for additional characterization and further information gathering. This can be either qualitative or quantitative information and shall be used to enhance the basic characterization and better define exposure groups, their profile, and the risks posed by exposure profiles.
126.96.36.199 Engineering controls shall be applied first. Until engineering controls are implemented or when engineering controls are not feasible, administrative controls or PPE shall be used. PPE shall be used as a last control measure.
188.8.131.52 Exposures shall be periodically re-characterized and reassessed in order to update exposure groups and exposure profiles.
184.108.40.206 The following records shall be maintained in accordance with NASA's record requirements and this NPR:
a. Lists of SEG's;
b. Exposure profiles; and
c. Judgments of acceptability.
220.127.116.11 The integrity of critical data shall be ensured by adherence to OSHA, NIOSH, or other recognized sampling and analytical methods using properly calibrated equipment with the National Institute of Standards and Technology (NIST) traceability, where applicable.
18.104.22.168 The OCHMO shall provide guidance and advice to NASA Centers on sampling, analytical methods, and equipment calibration.

126.96.36.199 Centers shall develop policies and procedures to ensure that proper sampling techniques, analytical methods, and equipment calibration are used throughout the data collection process.
188.8.131.52 Centers shall ensure adherence to OSHA, NIOSH, or other recognized sampling and analytical methods and use properly calibrated equipment with the NIST traceability, where applicable.
4.4.3 Process Description
184.108.40.206 Centers shall develop written policies and procedures for sampling, analytical methods, and equipment calibration utilizing methods established by professional or regulatory bodies. At a minimum, these requirements shall address sample planning, sampling methodology, pre-survey calibration, survey performance, sample collection, post-survey calibration, sample documentation, shipment of sample media, equipment calibration and maintenance, and recordkeeping.
220.127.116.11 Engineering, administrative, and PPE controls, in hierarchical order, shall be applied as appropriate whenever the sample exceeds the applicable OEL. Engineering controls shall be applied first. Until engineering controls are implemented or when engineering controls are not feasible, administrative controls or PPE shall be used. PPE shall be used as a last control measure.
18.104.22.168 Results shall be maintained in accordance with NASA recordkeeping requirements.
22.214.171.124 NASA Centers shall protect the reproductive health of the workforce and others from exposures to hazardous materials and articles (chemical, biological, radiological, and physical) that are known or suspected of being capable of posing a hazard to human reproduction.
126.96.36.199 Potential reproductive and developmental hazards shall be identified, and appropriate exposure control measures shall be implemented.
188.8.131.52 Exposures shall be kept As Low as Reasonably Practicable (ALARP) since short-term exposures to reproductive hazards can result in long-term health effects, and a developing fetus may also be adversely affected by exposures lower than those generally considered safe for adults.

126.96.36.199 Center EH organizations shall perform additional workplace hazard assessments upon the request or when changes occur to ensure existing controls (engineering, administrative, and PPE) are adequate to protect workers from reproductive hazards.
188.8.131.52 The additional workplace hazard assessment shall include:
a. Identification of chemical, biological, physical, and radioactive agents in the workplace that present a potential exposure risk;
b. A qualitative exposure assessment of the concerned worker;
c. A review of work practices and PPE used, and recommendations for additional control measures, if needed; and
d. A review of past EH reports and historical sampling results, if available.
184.108.40.206 Nanomaterial, as currently defined by NIOSH, may pose an unusual risk to human health due to their unique composition, reactivity, size, and ability to cross cell membranes. All work with manufactured nanomaterial shall be prudently conducted in a manner that is responsible and safe.
220.127.116.11 The 18.104.22.168 OCHMO shall provide guidance and advice to NASA Centers on nanotechnology.
22.214.171.124 The Director of Health and Medical Systems shall ensure Center nanotechnology policy and programs are assessed for efficacy through regular, periodic reviews.
126.96.36.199 Centers shall ensure that all work with manufactured nanomaterial adheres to NASA's requirements as per 188.8.131.52 of this document.
184.108.40.206 Centers with nanomaterial shall have written nanotoxicology programs that are designed and implemented to ensure all work with manufactured nanomaterial minimizes exposures to an ALARP level, or to other exposure standards as described in this NPR.
4.6.3 Process Description
220.127.116.11 Center nanotoxicology programs shall encompass the requirements of this section.
18.104.22.168 Transportation, storage, use, and disposal of manufactured nanomaterial shall be conducted in accordance with all Federal, state, local, Agency, and Center requirements.
22.214.171.124 Workers potentially exposed to manufactured nanomaterials shall be informed of the risks associated through training programs, safety data sheets, labeling, and signage.
126.96.36.199 Centers shall conform to best available work practices, such as, but not limited to, those from NIOSH, OSHA, or FDA for products that utilize nanotechnology and/or contain manufactured nanomaterial.
188.8.131.52 Centers shall conduct Hazard Assessments (HA's) prior to beginning work with manufactured nanomaterial.
184.108.40.206 HA's shall be conducted by a competent person who shall identify appropriate engineering controls, administrative controls, and personal protective equipment to ensure worker safety.
NOTE: A competent person is a person who has acquired through training, qualification, and experience, the knowledge, skills, and professional judgment to identify hazardous materials and/or articles and who has the designated ability to manage those substances and/or articles that are brought onto the Center. This is generally an American Board of Industrial Hygiene (ABIH) CIH.
220.127.116.11 HA's shall evaluate several factors, including, but not limited to, the physical and chemical properties of the nanomaterial, the process by which it will be generated and/or used, and the adequacy of existing engineering controls (e.g., fume hood, glove box).
NOTE: In some instances, the competent person may recommend collecting occupational exposure measurements (e.g., sampling) to further understand potential hazards or to identify specific processes or equipment requiring additional engineering controls.
18.104.22.168 Exposures to manufactured nanomaterial shall be kept to a minimum ALARP by utilizing the basic hierarchy of controls described below, as prescribed by a competent person with the exception of a material being in solution or embedded in substrate where it cannot become airborne.
NOTE: Although traditional OEL's exist for many of the materials from which nanomaterial is made, the OEL for a nanomaterial of these substances is not yet clear. As a result, NASA approach for controlling exposures to nanomaterial differs from those of traditional hazardous materials covered in the section entitled Occupational Exposure Assessment and Management.
a. Engineering. These controls may include local exhaust ventilation and localized filtration.
b. Administrative. It is important to incorporate administrative controls, such as scheduling maintenance of fume hoods on off hours, and limiting potential exposure time, into operations involving nanomaterial's due to the ambiguity about nanomaterial OELs. The incorporation of good work practices helps to minimize exposure to manufactured nanoparticles.
c. PPE. Typical chemistry laboratory apparel and PPE shall be worn when working with manufactured nanomaterial. This includes long pants, shirts, and shoes, as well as safety glasses, laboratory coats, gloves, and eye protection. If the nanomaterial can become airborne (not in solution or embedded in substrate), then respiratory protection is required. Open sandals, shorts, and skirts are prohibited. Respiratory protection shall be utilized when local exhaust ventilation and filtration are not available or feasible for work involving manufactured nanomaterial not suspended in liquids or embedded in substrate. However, the preferred method for manipulating manufactured nanomaterial is in solution, and every effort should be made to design and implement effective engineering controls for any operation where manufactured nanomaterial are used.
22.214.171.124 Spill management shall be addressed emphasizing that all debris resulting from the cleanup of a manufactured nanomaterial spill shall be handled as though it were hazardous and include procedures for access control and cleanup of both dry and wet materials.
126.96.36.199 NASA Centers shall evaluate the potential exposure issues involved with the use of hazardous materials and articles.
188.8.131.52 Hazardous materials and/or articles shall not be procured or otherwise acquired until hazards have been analyzed and adequate controls selected.
184.108.40.206 Hazardous materials and/or articles shall not be brought onto Centers until adequate controls have been implemented.
220.127.116.11 The OCHMO shall provide guidance and advice to NASA Centers on hazardous materials and articles acquisitions.
18.104.22.168 The Director of Health and Medical Systems shall ensure Center hazardous materials and articles acquisition policy and programs are assessed for efficacy through regular, periodic reviews.

An annual audiogram, if completed within six (6) months prior to termination, transfer, or retirement date, may serve as the final audiogram; and
h. When workers 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.
18.104.22.168 Audiometric testing shall be performed upon initial assignment, and annually thereafter, in accordance with 29 CFR 1910.95, Sections (g) and (h) and additionally as follows:
a. Audiologists and/or physicians knowledgeable in hearing conservation shall oversee all audiometric testing conducted by CAOHC-certified Occupational Hearing Conservationists;
b. Personnel who conduct audiometric testing shall be familiar with the provisions of this section;
NOTE: An STS is defined as a decline in hearing threshold, relative to the baseline audiogram, of an average of 10 dB or more at 2000, 3000, and 4000 Hz in either ear.
c. All baseline audiograms and confirmation audiograms following the identification of an STS shall be preceded by a period of at least 14 hours during which there shall be no exposure to noise above 82 dBA TWA, on or off the job.

d. If during any medical evaluation or audiometric examination the worker is identified as potentially unable to perform his or her job safely or has a hearing profile equal to or worse than that listed in Table 3 below, the worker and his or her employer shall receive a written notification of the requirement to perform a Functional Ability Evaluation. The written notification shall include results of pertinent work history and relevant conditions, e.g., visual impairment, that may affect ability to safely perform the work expected in the position held or to wear appropriate personal hearing protection equipment in a hazardous noise area.
|Hearing Threshold Level (dB)||25||25||25||35||45||45|
22.214.171.124 The requirements for handling threshold shifts are as follows:
a. The STS should be computed using the age corrections described in OSHA 29 CFR 1910.95, Appendix F;

d. A physician, audiologist, or CAOHC-certified Occupational Hearing Conservationist shall perform the hearing test and make the comparison;
e. If an STS is identified and a confirmation audiogram is not obtained 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;
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 worker shall be referred to an otolaryngologist or other qualified physician, or to an audiologist for further medical evaluation, 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). Persons 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. The baseline shall be revised to the STS test which shows the lower (more sensitive) value for the average of thresholds at 2000, 3000, and 4000 Hz.
(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 improved test which shows the lower (more sensitive) value for the average of thresholds at 2000, 3000, and 4000 Hz. Age corrections shall not be used when determining "improvement."
(3) An audiologist or physician may determine 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 worker, employer, and Center environmental health staff shall be notified of an STS in writing within 21 days of the determination of the STS;
l. If the worker's uncorrected hearing threshold level (HTL), without age correction (averaging 2000, 3000, and 4000 Hz) is 25 dB or greater above audiometric zero in the same ear as the STS, a work relatedness determination shall be made;
m. Based on the best available information, a physician or other licensed health care professional, in consultation with the employer, shall determine whether the noise-induced STS is work-related;
n. Unless a physician has determined that the STS is not work-related, the following actions shall be taken:
(1) The worker'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 worker 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 worker shall be refitted, as necessary, with HPDs offering a greater sound attenuation.
(5) The worker shall be re-trained on the hazardous effects of noise and the need to use hearing protection.
(6) The work environment(s) shall be re-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 as a first priority to reduce the potential for exposure to the action level.
(7) Any administrative and work practices being utilized to reduce noise exposures shall be reevaluated for effectiveness.
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 worker reassignment; and
q. Where the same worker experiences any subsequent work-related STS as a result of occupational noise exposure, the work environment(s) shall be re-evaluated. If the worker continues to work in the hazardous noise area(s), engineering and/or administrative controls shall be employed that reduce that worker's noise exposure to no more than 50 percent of what was previously allowed for that worker.
126.96.36.199 Unless a physician has determined a standard threshold shift is not work related or aggravated by occupational noise, the following steps shall be taken when an STS occurs:
a. Workers shall be referred to an otolaryngologist/physician knowledgeable in hearing conservation or to an audiologist for more comprehensive testing when it is suspected medical pathology of the ear is caused or aggravated by the wearing of hearing protectors;
b. Workers shall be informed of the need for an otological examination if a medical pathology of the ear unrelated to the use of hearing protectors is suspected; and
c. Workers shall be referred for persistent failure to obtain a valid audiogram.
188.8.131.52.1 To support the identification of larger changes in hearing that may be medically significant or result in communication difficulties, the following American Academy of Otolaryngology—Head and Neck Surgery occupational hearing referral criteria are recommended:
(1) An average HTL at 500, 1000, 2000, and 3000 Hz greater than 25 dB HTL in either ear (Baseline Audiogram).
