Label Abbreviations & Descriptions
Name: The substances are primarily listed by the chemical name as it appears in the OSHA PELs, 29 CFR 1910.1000, TABLES Z-1, Z-2, Z-3; the ACGIH TLVs; or by common name.

NFPA 704: National Fire Protection Association’s Standard System for the Identification of the Hazards of Materials for Emergency Response. The standard presents a simple, readily recognized, and easily understood system of markings (commonly referred to as the “NFPA hazard diamond”) that provides an immediate general sense of the hazards of a material and the severity of these hazards as they relate to emergency response.
Sampling method for OSHA compliance.
SLTC: Salt Lake Technical Center, OSHA. Sandy, UT 84070.
IMIS, IMIS code no.: The substance code currently assigned by OSHA to each substance in the integrated management system. IMIS Codes are reported on pre-printed OSHA-91B forms.
The following method status classifications have been assigned to 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|
|Not Validated:||literature review and very limited or no evaluation data.|
Note special instructions on sampling or obtaining sampling media from the SLTC. These instructions pertain to OSHA and 18(b) or 7(c)(1) state programs.
Analytical method instruments: Describesthe type of analysis performed at the SLTC. The following abbreviations are used:
|AAS||Atomic absorption spectroscopy|
|AAS/AES||Atomic absorption spectroscopy or atomic emission spectroscopy|
|AES||Atomic emission spectroscopy|
|CSC||Coconut shell charcoal|
|CVAA||Cold vapor atomic absorption spectroscopy|
|DID||Discharge ionization detector|
|FID||Flame ionization detector|
|FPD||Flame photometric detector|
|FTIR||Fourier transform infrared|
|GC-FID & GC-MS||Gas Chromatography-Flame Ionization Detector & Gas Chromatography-Mass Spectroscopy|
|GFF||Glass fiber filter|
|HPLC||High-performance liquid chromatography|
|ICP||Inductively coupled plasma|
|MCEF||Mixed cellulose ester filter|
|OES||Optical Emission Spectroscopy|
|OVS||OSHA versatile sampler|
|PCM||Phase contrast microscopy|
|TCD||Thermal conductivity detector|
|TEA||Thermal energy analyzer|
|UHPLC||Ultra High-Performance Liquid Chromatography|

Detector tubes, chip measurement systems and direct reading instrument information has not been reviewed, except as noted.
Colorimetric detector tubes and Dräger Chip Measurement Systems (CMS) are used for screening to determine whether additional sampling is needed. If these readings exceed ½ the PEL, CSHOs should conduct additional sampling.
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. Omission of other manufacturers tubes does not mean the tubes have been found unsatisfactory.

NTP, carcinogenic classification as listed in or prior to the National Toxicology Program's (NTP) Report on Carcinogens (RoC). Search NTP for updated information.
Known To Be Human Carcinogens (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 Human Carcinogens (also known 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,
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,
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 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.
AIHA Emergency Response Planning Guidelines - ERPG-1/ERPG-2/ERPG-3:
ERPGs are air concentration guidelines for single exposures to agents and are intended for use as tools to assess the adequacy of accident prevention and emergency response plans, including transportation emergency planning, community emergency response plans and incident prevention and mitigation.
