HEALTH FACTORS

The Office of Occupational Medicine is currently reviewing and updating this section for specific chemicals.

NTP, carcinogenic classification as listed in or prior to the National Toxicology Program's (NTP) Eleventh Annual Report on Carcinogens. Search NTP for updated information.
    Known To Be Human Carcinogen (also known as HUMAN CARCINOGEN):
    There is sufficient evidence of carcinogenicity from studies in humans * , which indicates a causal relationship between exposure to the agent, substance, or mixture, and human cancer.

    Reasonably Anticipated to be a Human Carcinogen (also know as SUSPECT HUMAN CARCINOGEN):
    There is limited evidence of carcinogenicity from studies in humans * , which indicates that causal interpretation is credible, but that alternative explanations, such as chance, bias, or confounding factors, could not adequately be excluded,
    or

    there is sufficient evidence of carcinogenicity from studies in experimental animals, which indicates there is an increased incidence of malignant and/or a combination of malignant and benign tumors (1) in multiple species or at multiple tissue sites, or (2) by multiple routes of exposure, or (3) to an unusual degree with regard to incidence, site, or type of tumor, or age at onset,
    or

    there is less than sufficient evidence of carcinogenicity in humans or laboratory animals; however, the agent, substance, or mixture belongs to a well-defined, structurally related class of substances whose members are listed in a previous Report on Carcinogens as either known to be a human carcinogen or reasonably anticipated to be a human carcinogen, or there is convincing relevant information that the agent acts through mechanisms indicating it would likely cause cancer in humans.

    *This evidence can include traditional cancer epidemiology studies, data from clinical studies, and/or data derived from the study of tissues or cells from humans exposed to the substance in question that can be useful for evaluating whether a relevant cancer mechanism is operating in people.

IARC, carcinogenic classification as indicated by International Agency for Research on Cancer (IARC), IARC Monographs on the Evaluation of the Carcinogenic Risk to Humans. Data includes chemicals covered through Volume 88.
    Group 1: The agent (mixture) is carcinogenic to humans.
    The exposure circumstance entails exposures that are carcinogenic to humans.

    Group 2
    Group 2A: The agent (mixture) is probably carcinogenic to humans.
    The exposure circumstance entails exposures that are probably carcinogenic to humans.
    Group 2B: The agent (mixture) is possibly carcinogenic to humans.
    The exposure circumstance entails exposures that are possibly carcinogenic to humans.

    Group 3: The agent (mixture or exposure circumstance) is not classifiable as to its carcinogenicity to humans.

    Group 4: The agent (mixture) is probably not carcinogenic to humans.

SYMPTOM(S), potential symptoms as a result of inhalation, skin absorption, ingestion, or skin or eye contact. As listed in NIOSH Pocket Guide to Chemical Hazards (NIOSH No. 85-114), condensed from the NIOSH/OSHA Occupational Health Guidelines for Chemical Hazards (NIOSH No. 81-123).

HEALTH EFFECTS, Principal effect(s) of exposure to each substance, listed by OSHA Health Code and Health Effects. Health codes are used in determining if a violation of an air contaminant standard is serious or other-than- serious, based on guidelines in the Field Operations Manual, OSHA Instruction CPL 2.45B, chapter IV. All Health Codes and Health Effects are scheduled to be reviewed and updated under contract. For some chemicals, additional toxicology information has been added from other sources. Abbreviations for this information includes: SKIN IRR = Skin irritation; SKIN ABS = Skin Absorption; INGES ACUTE = Ingestion Acute; and INGES CHRONIC = Ingestion Chronic.

ORGAN, the organs which are affected by exposure to each substance. As listed in NIOSH Pocket Guide to Chemical Hazards (NIOSH No. 85-114), condensed from the NIOSH/OSHA Occupational Health Guidelines for Chemical Hazards (NIOSH No. 81-123).

HEALTH GUIDELINE, guidelines summarize pertinent information about chemicals for workers and employers as well as for physicians, industrial hygienists, and other occupational safety and health professionals who may need such information to conduct effective occupational safety and health programs. Recommendations may be superseded by new developments; readers are therefore advised to regard these recommendations as general guidelines and to determine periodically whether new information is available.

    CLASS, method classifications.

    The following method status classifications have been assigned to OSHA methods. Some of the classifications are obsolete, but will be encountered in various OSHA methods. NIOSH method classification is taken from the method evaluation status published in their methods.
Fully Validated:sampling and analytical methods that have been thoroughly evaluated for sampler capacity, analytical recovery, storage stability, precision, and limits of detection and quantitation by following established OSHA methods evaluation guidelines
Partially Validated:sampling and analytical methods that have been partially evaluated for sampler capacity, analytical recovery, storage stability, precision, and limit of quantitation by following established OSHA methods evaluation guidelines
Validated:similar to Fully Validated
Validated analytical method:analytical method that was thoroughly evaluated. The sampling method was not tested.
Stopgap:similar to Partially Validated
Not Validated:literature review and very limited or no evaluation data.

    Note special instructions on sampling or obtaining sampling media from the Salt Lake Technical Center. These instruction pertain to OSHA and 18(b) or 7(c)(1) state programs.
SECONDARY SAMPLING/ANALYTICAL METHOD (SAM2), Detector Tubes and Direct reading instrument information has not been reviewed, except as noted.
    ANL, any analytical method used in conjunction with a secondary sampling method. Some of these are NIOSH methods which are not in use by Salt Lake Technical Center.

    For other subheadings see Primary Sampling/Analytical Method(SLC1) above.

    DET TUBE, Detector Tubes are used for screening to determine whether additional sampling is needed. If detector tube readings exceed 1/2 the PEL, CSHOs should sample with the SLC1 method, if available. Under certain conditions, detector tubes can be used for compliance purposes. Contact SLTC for further information.

      NOTE: OSHA has evaluated detector tubes for internal use; however, the number and type of tubes is limited. OSHA evaluates detector tubes primarily to select tubes for OSHA use. OSHA does not certify detector tubes, nor endorse products of any manufacturer. The Safety Equipment Institute certifies detector tubes and more information regarding their program can be found at their www.seinet.org site. Omission of other manufacturers tubes does not mean the tubes have been found unsatisfactory.
COND, used primarily to specify HPLC conditions for the purpose of grouping chemicals together for analysis.

ART, Articles from published literature which may be prospective starting points for sampling or analysis of the chemical of interest.

WIPE, Indicates whether wipe samples can be used. For some chemicals, specific filter and solvent information is included. Information in this field has not been extensively reviewed.
