HazCom 2012 Nomenclature Descriptors
Substance – chemical elements & their compounds in natural state or obtained by any production process, including additives and impurities, but excluding any solvent which may be separated w/o affecting stability or changing composition.
Chemical – any substance or mixture of substances
Hazardous Chemical – any chemical classified as physical or health hazard, simple asphyxiant, combustible dust, pyrophoric gas or HNOC.
Container – any bag, barrel, bottle, box, can, cylinder, drum, reaction vessel, storage tank, or the like that contains a hazardous chemical.
HazCom 2012 Nomenclature Descriptors
Classification – Process used to: ID relevant data on hazards
Review data to determine hazards
Decide if chemical is hazardous using definition of hazardous chemical
Determine degree of health & physical hazards by comparing data with criteria for health & physical hazards
Common Name - Any designation or ID such as code name, code number, trade name, brand name or generic name used to identify chemical other than by chemical name
HazCom 2012 Nomenclature Descriptors
Immediate Use – Hazardous chemical will be under control of & used only by person who transfers it from labeled container & only within work shift in which it is transferred
Exposure or Exposed – Employee subjected in course of employment to chemical that has a physical or health hazard, & includes potential exposure
GHS HazCom Nomenclature Descriptors
Hazard Class – the nature of the physical or health hazards, e.g., flammable solid, carcinogen, oral acute toxicity.
Hazard Category – the division of criteria within each hazard class, e.g., oral acute toxicity and flammable liquids include four hazard categories. These categories compare hazard severity within a hazard class and should not be taken as a comparison of hazard categories more generally.
Hazard Statement – Statement assigned to hazard class & category that describes nature of hazard(s) for a chemical, including degree of hazard, e.g., fatal if swallowed, causes severe skin burns and eye damage, may cause drowsiness or dizziness.
HazCom 2012 Nomenclature Descriptors
Hazard not otherwise Classified (HNOC) – Adverse physical or health effect ID’d through evaluation of scientific evidence during classification process that doesn’t meet specified criteria for physical & health hazard classes.Doesn’t extend coverage to adverse physical & health
effects for hazard class, but effect either falls below cut-off value/concentration limit of hazard class or is under GHS hazard category not adopted by OSHA (acute toxicity Category 5)
HazCom 2012 Nomenclature Descriptors
• Physical Hazard – Chemical that is classified as posing one of
following hazardous effects:• Explosive• Flammable (gases, aerosols, liquids, or solids)• Oxidizer (liquid, solid or gas)• Self-reactive• Pyrophoric (liquid or solid)• Self-heating• Organic peroxide
• Health Hazard – Chemical classified as posing one of following
hazardous effects:• Acute toxicity (any route of exposure)• Skin corrosion or irritation• Serious eye damage or eye irritation• Respiratory or skin sensitization• Germ cell mutagenicity• Carcinogenicity• Reproductive toxicity
HazCom 2012 Nomenclature Descriptors
Label – Appropriate group of written, printed or graphic
information elements concerning hazardous chemical affixed
to, printed on, or attached to immediate container of hazardous
chemical, or to outside packaging.
Label Elements – Chemical Name, specified pictogram,
hazard statement, signal word & precautionary statement for
each hazard class & category.
Pictogram – Composition that may include symbol plus other
graphic elements, such as border, background pattern, or
color, intended to convey specific information about hazards of
chemical• 8 mandatory pictograms for application to hazard category; 1 non-
mandatory
HazCom 2012 Nomenclature Descriptors
Precautionary Statement – Phrase that describes recommended
measures that should be taken to minimize or prevent adverse effects
resulting from exposure to hazardous chemical, or improper storage or
handling.
Product Identifier – the name or number used for a hazardous
chemical on a label or in the SDS. It provides a unique means by which
the user can identify the chemical. The product identifier used shall
permit cross-references to be made among the list of hazardous
chemicals required in the written hazard communication program, the
label and the SDS.
Signal Word – Word used to indicate relative level of severity of hazard
& alert reader to potential hazard on label.• “Danger" used for more severe hazards
• “Warning" used for less severe hazards
• “Caution” not used by OSHA but by EPA
HazCom 2012 Nomenclature Descriptors
Safety Data Sheet – written or printed material concerning
a hazardous chemical that is prepared in accordance with
specified format outlined in GHS HazCom.
Trade Secret – Confidential formula, pattern, process,
device, information or compilation of info used in employer's
business, and gives employer opportunity to obtain
advantage over competitors who don’t know or use it. Appendix E of GHS HazCom sets out criteria to be used in
evaluating trade secrets.
Work Area – Room or defined space in workplace where hazardous chemicals produced or used, & employees present
HazCom 2012 Nomenclature Descriptors
Mixture – a combination or a solution composed of two or more substances in which they do not react.
Pyrophoric Gas – a chemical in a gaseous state that will ignite spontaneously in air at a temperature of 130 degrees F (54.4 degrees C) or below.
Simple Asphyxiant – a substance or mixture that displaces oxygen in the ambient atmosphere, and can thus cause oxygen deprivation in those who are exposed, leading to unconsciousness and death.
