  2. Office of Environmental Health & Safety Pam Fatland – Manager, Safety Program Tulane University - Office of Environmental Health & Safety (OEHS)

  3. To become familiar with: Objectives Tulane University - Office of Environmental Health & Safety (OEHS)

  4. What is GHS? • A worldwide initiative to promote standard criteria for classifying chemicals • Based on criteria-based definitions of physical, health, and environmental hazards • OSHA has not adopted environmental aspects because it does not have jurisdiction over environmental matters Tulane University - Office of Environmental Health & Safety (OEHS)

  5. OSHA HAZARD COMMUNICATION STANDARD • Revised March 26, 2012 (29 CFR 1910.1200) • Includes certain aspects of globally harmonized system of classification and labeling of chemicals (GHS) • Purpose: To understand chemical hazards in the workplace and how to protect yourself Tulane University - Office of Environmental Health & Safety (OEHS)

  6. OSHA HAZARD COMMUNICATION STANDARD Major changes include: • “Right to Know” changes to “Right to Understand” • Several definitions revised, changed, or deleted • “Hazard determination” now “hazard classification” • Significant changes to labels • Specified format for safety data sheets (formerly MSDSs) Tulane University - Office of Environmental Health & Safety (OEHS)

  7. OSHA HAZARD COMMUNICATION STANDARD • Under the OSHA HAZCOM standard, manufacturers of chemicals are required to classify the chemicals they produce and transmit that information to customers on labels and Safety Data Sheets (SDSs) Tulane University - Office of Environmental Health & Safety (OEHS)

  8.

  15. Transfer Containers Required Information Transfer containers can use GHS elements as stated on the shipping containers OR Can use label alternatives that meet the requirements of the standard Tulane University - Office of Environmental Health & Safety (OEHS)

  16. Transfer Containers Required Information (unless the container is intended for the immediate use of the employee who performed the transfer) • Product Identifier • Words, Pictures, or Symbols • General hazard information • Specific information about physical and health hazards Tulane University - Office of Environmental Health & Safety (OEHS)

  17. Product Identifier • The chemical name, Chemical Abstracts Service (CAS) Registry Number, or any other information that reveals the precise chemical designation of the substance. • It provides a unique means by which the user can identify the chemical. Tulane University - Office of Environmental Health & Safety (OEHS)

  18. Pictogram • A composition that may include a symbol plus other graphic elements, such as a border, background pattern, or color, that is intended to convey specific information about the hazards of a chemical. Tulane University - Office of Environmental Health & Safety (OEHS)

  19. Pictograms Tulane University - Office of Environmental Health & Safety (OEHS)

  20. Chemical Classifications Explosives, Self-reactive substances, Organic Peroxides – Chemicals which can release pressure, gas, and heat when subjected to shock, pressure, or high temperature • Examples: nitroglycerin, TNT, picric acid, sodium azide Exploding Bomb Tulane University - Office of Environmental Health & Safety (OEHS)

  21. Chemical Classifications Flammables, Pyrophorics, Self-heating substances, Self-reactives, Substances which emit flammable gas, organic peroxides – Chemicals which can ignite easily and burn rapidly, either spontaneously (pyrophoric) or from exposure to a high-temperature environment (autoignition), or a spark or open flame • Examples: gasoline, solvents, ether, hexane, alcohol, acetone Flame Tulane University - Office of Environmental Health & Safety (OEHS)

  22. Chemical Classifications Oxidizers, Organic Peroxides – Chemicals which promote combustion • Examples: oxygen, perchloric acid, nitric acid Note: Keep oxidizers away from flammables. Flame Over Circle Tulane University - Office of Environmental Health & Safety (OEHS)

  23. Chemical Classifications Corrosive to metals, Skin corrosion, Serious eye damage – Chemicals which can cause irreversible alterations/chemical burns to human tissue (Acids/Caustics) • Examples: sulfuric acid, nitric acid, hydrofluoric acid, ammonia gas, hydrochloric acid Corrosion Tulane University - Office of Environmental Health & Safety (OEHS)

  24. Chemical Classifications Carcinogens, Respiratory Sensitizers, Reproductive toxicity, Target organ toxicity, Mutagens, Aspiration hazards – Chemicals which can cause or are suspected of causing cancer or health hazards • Examples: benzene, chloroform, formaldehyde, carbon tetrachloride, dichloromethane Health Hazard Tulane University - Office of Environmental Health & Safety (OEHS)

  25. Chemical Classifications Gases Under Pressure – Gases which are stored in a container (cylinder, lecture bottle) under pressure • Examples: argon, nitrogen, chlorine, carbon dioxide, oxygen, acetylene Note: Cylinders must be chained and have protective caps in place. Gases Under Pressure Tulane University - Office of Environmental Health & Safety (OEHS)

  26. Chemical Classifications Irritant, Skin sensitizer, Acute toxicity, Transient Target Organ Effects (Narcotic Effects, Respiratory Tract Irritation) – Chemicals which can cause reversible inflammatory reactions (watery eyes, itchy skin) • Examples: formaldehyde, ammonia, hydrogen sulfide Exclamation Mark Tulane University - Office of Environmental Health & Safety (OEHS)

  27. Chemical Classifications Acute Toxicity – The ability of a chemical to produce a health effect or injury once it reaches a susceptible site in or on the body • Examples: lead and its salts, arsenic, dimethyl mercury, silica dust, cyanides, hydrogen bromide Skull and Crossbones Tulane University - Office of Environmental Health & Safety (OEHS)

  28. Chemical Classifications Aquatic Toxicity – The ability of a chemical to be hazardous to the aquatic environment Note: This pictogram is not enforced by OSHA. Environment Tulane University - Office of Environmental Health & Safety (OEHS)

  29. Chemical Classifications Under the GHS classifications, chemicals are also placed into categories. (It should be noted that these categories are OPPOSITE from the numbering systems that have traditionally been used in the U.S. such as the NFPA or HMIS ratings in which 4 was the most hazardous and 0 or 1 the least hazardous.) In the GHS system, Category 1 would be the most hazardous. Tulane University - Office of Environmental Health & Safety (OEHS)

  30. Signal Words A word used to indicate the relative level of severity of hazard and alert the reader to a potential hazard on the label. “Danger” “Warning” Tulane University - Office of Environmental Health & Safety (OEHS)

  31. Hazard Statement A statement assigned to a hazard class and category that describes the nature of the hazard of a chemical including, where appropriate, the degree of hazard. Tulane University - Office of Environmental Health & Safety (OEHS)

  32. Precautionary Statement A phrase that describes recommended measures that should be taken to minimize or prevent adverse effects resulting from exposure to a hazardous chemical, or improper storage or handling. Tulane University - Office of Environmental Health & Safety (OEHS)

  33. Supplier Information • Company Name • Company Address • Company Phone • Emergency Phone Tulane University - Office of Environmental Health & Safety (OEHS)

  34. Supplementary Information • Further detail of the hazards • Hazards not yet incorporated into GHS • Information not required by GHS Tulane University - Office of Environmental Health & Safety (OEHS)

  35. CHEMICAL LABELS – General Information • Required on all incoming containers, all transfer containers that will be left for a period of time, and on all containers that will be used by more than one person • You can label an entire shelf instead of each individual container if all containers on the shelf contain the same thing (Ex. specimen containers of ethanol) • Labels must be legible, in English with the full name of the chemical spelled out (no symbols or abbreviations) Tulane University - Office of Environmental Health & Safety (OEHS)

  36. Improper Labeling Tulane University - Office of Environmental Health & Safety (OEHS)

  37. Improper Labeling - Abbreviations Tulane University - Office of Environmental Health & Safety (OEHS)

  38. Documents that inform you of the hazards associated with a chemical and how to protect yourself from those hazards SDSs must be readily accessible in the work area where the chemicals are used Each company publishes its own SDSs with their address and emergency contact information. Thus if you have a chemical such as acetone from two different manufacturers, you will need an SDS from each company.
