2 Answers the question “What does OSHA mean by…?”  HazCom 2012 Nomenclature Descriptors The terms used for establishing the organization, the scope, and the meaning of words in the standard.  Hazard Descriptions Establishes meaning for physical characteristics. Types of Definitions in Standard Those that have been added, changed, or are important

3 Classification Chemical Common Name Container Exposure or Exposed Hazard Category Hazard Class Hazard not otherwise Classified (HNOC) Hazard Statement Hazardous Chemical Health Hazard Immediate Use Label Label Elements Physical Hazard Pictogram Precautionary Statement Product Identifier Safety Data Sheet Signal Word Substance Trade Secret Work Area HazCom 2012 Nomenclature Descriptors

4 Mixture Pyrophoric Gas Simple Asphyxiant Hazard Descriptors

5  Substance  Chemical HazCom 2012 Nomenclature Descriptors  Hazardous Chemical  Container

6  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

7  Classification – A Process  Common Name HazCom 2012 Nomenclature Descriptors

8  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

9  Immediate Use  Exposure or Exposed GHS HazCom Nomenclature Descriptors

10  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

11  Hazard Class  Hazard Category  Hazard Statement HazCom 2012 Nomenclature Descriptors 1 2

12  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

13  Hazard not otherwise Classified (HNOC) HazCom 2012 Nomenclature Descriptors

14  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

15  Physical Hazard  Health Hazard HazCom 2012 Nomenclature Descriptors

16 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

17  Label.  Label Elements  Pictogram HazCom 2012 Nomenclature Descriptors

18  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

19  Precautionary Statement  Product Identifier  Signal Word HazCom 2012 Nomenclature Descriptors

20  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

21  Safety Data Sheet  Trade Secret  Work Area HazCom 2012 Nomenclature Descriptors

22  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

23  Mixture  Pyrophoric Gas Hazard Descriptors  Simple Asphyxiant >130°F O2O2

24  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.
