Hazard Communication: GHS Training Valley City State University | Facilities Services • GHS is an acronym for the Globally Harmonized System for the classification and labeling for chemicals. • G = Globally • H= Harmonized • S= System • GHS was developed by the United Nations and is implemented worldwide. • The goal of GHS is to ensure employers, employees, and the public are provided with adequate, practical, reliable, and comprehendible information on hazardous chemicals. What is GHS? “A worldwide effort to standardize hazardous communication.” • In 2012, OSHA adopted the NEW GHS system. • What does this mean for VCSU? • New format for MSDSs Safety Data Sheets • New GHS labeling elements • • • • Pictograms Signal words Hazard statements Precautionary statements The NEW GHS System “The New Globally Harmonized System” SAFETY DATA SHEETS **See handout for new layout** • Primary use: the workplace • The SDSs should provide comprehensive information about a chemical substance or mixture. • Employers and workers use the SDSs as a source of information about hazards and to obtain advice on safety precautions. Role of SDSs • The new SDSs will have 16 categories (all the same and in the same location) • • • • • • • • • • • Identification of the substance or mixture and of the supplier Hazards identification Composition/information on ingredients First aid measures Firefighting measures Accidental release measures Handling and storage Exposure controls/personal protection Physical and chemical properties Stability and reactivity Toxicological information New SDS Format • These categories are mandated, but not enforced by OSHA • • • • • Ecological information (EPA) Disposal considerations (EPA) Transport information (DOT) Regulatory information Other information including information on preparation and revision of the SDSs. New SDS Format (cont.) • • • • GHS product identifier Other means of identification Recommended use of the chemical and restrictions on use Supplier’s details (including name, address, phone number, etc.) • Emergency phone number 1. Identification of the Substance/Mixture & Supplier • GHS classification of the substance/mixture and any national or regional information. • Categorized in 4 classes– from severe to not severe • GHS label elements, including precautionary statements (hazard symbols may be provided) • Other hazards which do not result in classification (ex. dust explosion hazard– those that are not covered by GHS) Hazards Identification • Substance • • • • • Chemical identity Common name, synonyms, etc. Impurities and stabilizing additives HNOC (Hazards not otherwise categorized)– new to GHS Mixture The chemical identity and concentration or concentration ranges of all ingredients which are hazardous within the meaning of the GHS and are present above their cutoff levels. Composition/Information on Ingredients • Description of necessary measures, subdivided according to the different routes of exposure (ex. inhalation, skin and eye contact, and ingestion) • Most important symptoms/effect, acute and delayed • Indication of immediate medical attention and special treatment needed, if necessary First Aid Measures • Suitable and unsuitable extinguishing media • Specific hazards arising from the chemical (ex. nature of any hazardous combustion products) • Special protective equipment and precautions for firefighters Firefighting Measures • Personal precautions, protective equipment, and emergency procedures • Environmental precautions • Methods and material for containment and cleaning up Accidental Release Measures • Precautions for safe handling • Conditions for safe storage, including any incompatibilities Handling and Storage • Control parameters (ex. occupational exposure limit values) • Appropriate engineering controls • Individual protection measures, such as personal protective equipment • Employees should be asking, “How do I protect myself?” Exposure Controls/ Personal Protection • • • • • • • • Appearance Odor Odor threshold pH Melting point/freezing point Initial boiling point and boiling range Flash point Evaporation rate Physical and Chemical Properties • • • • • • • Flammability (solid, gas) Upper/lower flammability or explosive limits Vapor pressure Vapor density Relative density Solubility(ies) Etc. Physical and Chemical Properties (cont.) • • • • • Chemical stability Possibility of hazardous reactions Conditions to avoid (static discharge, shock, or vibration) Incompatible materials Hazardous decomposition products Stability and Reactivity • Information on the likely routes of exposure (inhalation, ingestion, skin and eye contact) • Symptoms related to the physical, chemical, and toxicological characteristics • Delayed and immediate effects and also chronic effects from short-and long-term exposure • Numerical measures of toxicity Toxicological Information • Not required for OSHA • • • • • Eco toxicity (aquatic and terrestrial where available) Persistence and degradability Bio accumulative potential Mobility in soil Other adverse effects Ecological Information (new) • Description of waste residues and information on their safe handling and methods of disposal, including the disposal of any contaminated packaging. Disposal Considerations • Under DOT Jurisdiction Transport Information • Safety , health, and environmental regulations specific for the product in question. Regulatory Information • Mostly for shipping and receiving. • This section will include the manufacturer date of the chemical and the date the SDS was revised. Other Information GHS LABELING **See handout for new layout** • • • • • • • Product Identifier- chemical identity Supplier Identification- name, address, etc. Precautionary Statements- advice* Hazard Pictograms- visual warning* Signal Words- degree of hazard* Hazard Statements- nature of hazard* Supplemental Information- additional information about the substance GHS Labeling GHS Label • Pictograms will have a black symbol on a white background with a red diamond border/frame. Label: Pictogram Shape, Color, and Meaning • Signal words are used to emphasize hazard and discriminate between levels of hazard. • The signal word indicates the relative degree of severity of a hazard. The signal words used in GHS are: • “DANGER” (more severe) • “WARNING” (less severe) • **NOTE** “CAUTION” is NOT a signal word for the GHS. Label: Signal Words • A statement is assigned to a hazard class and category that describes the nature of the hazard(s) of a chemical; including, where appropriate, the degree of hazards. • Example for flammable liquids: • • • • • • • • Category 1– Extremely flammable liquid and vapors Category 2– Highly flammable liquid and vapor Category 3– Flammable liquid and vapor Category 4– Combustible liquid Fatal if swallowed Toxic if swallowed Harmful if swallowed May be harmful if swallowed Label: Hazard Statements • Precautionary Statement– a phrase that describes recommended measures to be taken to minimize or prevent adverse effects resulting from exposure to a hazardous chemical or improper storage or handling. • Ex. wear protective gloves, wear splash protection for face, keep away from heat/sparks/open flame • All labels and warnings shall be in English, and prominently displayed or readily available. Label: Precautionary Statements • Needs all the information from the original shipping label OR • Product identifier & words, pictures, symbols which provide at least general information regarding the hazards and which will provide the specific information regarding the physical and health hazards OR • Signs, placards, process sheets, batch tickets, operation procedures, etc. for stationary containers.
