Presentation Transcript

  1. Hazard Communication Office of Environmental Health and Safety Hunter College of CUNY

  2. Overview • Understanding the Hazard Communication Standard (29 CFR 1910.1200) • Chemical Properties and Characteristics • Labels • Spill Procedures • MSDS – Material Safety Data Sheets CUNY HazCom

  3. Purpose • The Hazard Communication Standard was created to ensure that the hazards of all chemicals produced or imported are evaluated, and that this information is transmitted to all employees CUNY HazCom

  4. Hazard Communication = Right to Know Employees have the right to know what kinds of hazardous chemicals they work with or are exposed to in their work environment and what possible health effects these chemicals might pose CUNY HazCom

  5. Elements of a Written Hazard Communication Program • Staff Responsibilities • Labeling Procedures • MSDS Procedures (obtaining / maintaining) • Training Program CUNY HazCom

  6. Information Requirements • Employees must be informed of: • Requirements of the Hazard Communication Standard • Operations in work areas where there are hazardous chemicals • Location/availability of written Hazard Communication Program CUNY HazCom

  7. Training Requirements • Employees must be trained in • Methods to detect the presence or release of hazardous chemicals • Physical and health hazards of chemicals in work area • Personal protection CUNY HazCom

  8. Where will you find chemicals at CUNY? • Cleaning supplies • Bleach, ammonia, detergents • Paint Shop • Paints, paint thinners, paint strippers • Laboratories • Assorted chemicals and chemical waste • Mechanical Rooms / Boiler Rooms • Oils, grease, cleaners CUNY HazCom

  9. What is a Hazardous Chemical? 2 Types of hazards: • Physical hazard • Flammables • Corrosives • Reactives • Health hazard Causing acute or chronic health effects (Neurotoxin, carcinogen, mutagen, teratogen, irritant, etc.) CUNY HazCom

  10. Flammables • Aerosols • Gases • Liquids • Solids CUNY HazCom

  11. Flammability FLAMMABLE = IGNITE EASILY • Vaporizes quickly at room temperature • May cause dizziness, nausea, and headaches if inhaled • Reacts violently with oxidizers CUNY HazCom

  12. Examples of Common Flammable Materials • Gasoline • Alcohol • Paint Thinner • Aerosol cans CUNY HazCom

  13. Fire Triangle 3 Necessary Ingredients for Fire FUEL something that will burn AIR oxygen IGNITION SOURCE spark CUNY HazCom

  14. Corrosives • Solid • Liquid • Gas CUNY HazCom

  15. Corrosivity CORROSIVE = BURNS • Destroy or damage living tissue irreversibly • Acids (low pH) or Caustics (high pH) CUNY HazCom

  16. The pH Scale CUNY HazCom 16 CUNY HazCom

  17. Examples of Common Corrosive Materials • Bleach (Sodium Hypochlorite) • Ammonia • Vinegar (Acetic Acid) CUNY HazCom

  18. Reactives States • Solids • Liquids • Gases Types • Air or water reactive • Shock, heat or friction sensitive • Explosive CUNY HazCom

  19. Examples of Common Reactive Materials • Metallic sodium • Metallic calcium • Dry picric acid Reactives should only be found in laboratories and should be carefully stored and monitored. CUNY HazCom

  20. Toxicity TOXIC = POISONOUS High Toxicity – small dose causes severe effect Chronic Toxicity – effect from repeated exposure over long periods of time Acute Toxicity – immediate and severe effect CUNY HazCom

  21. Classes of Toxicity Carcinogens - cancer causing or potentially cancer causing Irritants - non-severe, short term effect that is reversible Sensitizers - may cause allergic reaction after repeated exposure CUNY HazCom

  22. NFPA Hazard Diamond CUNY HazCom CUNY HazCom

  23. Labels • Every bottle ordered and received should come with an affixed label containing: • Name of product and constituents • Hazards • Manufacturer’s Name CUNY HazCom

  24. User Labeling • EVERY bottle must be labeled to identify its contents (even soap and water, if there is no original label) • You may use a piece of tape, a • sharpie, or print out a label – as • long as it is clearly legible and • includes the commonly • recognized name of the contents • (not the chemical formula) and its • hazard(s) Rubbing Alcohol Flammable CUNY HazCom

  25. Old Chemical Bottles Do not keep old bottles of chemicals that you will not use If a label is deteriorating or falling off, make a new one or the chemical will be considered as an UNKNOWN CUNY HazCom

  26. Routes of Exposure • Breathing (inhalation) • Skin contact (dermal absorption) • Swallowing (ingestion) • Puncture (injection) CUNY HazCom

  27. PPE Know what Personal Protective Equipment (PPE) is available and where to get it • Gloves • Eye protection (safety glasses, goggles) • Respiratory Protection • Apron / coveralls Some people may be sensitive or allergic to latex gloves CUNY HazCom

  28. What should you do if you spill a chemical or find a spilled chemical? CUNY HazCom

  29. Small Spill Clean up a spill only if you: • Are familiar with the substance that was spilled • Know the substance’s toxicity • Have adequate personal protective equipment • Feel completely comfortable cleaning it up CUNY HazCom

  30. Large Spill For a large spill that requires assistance to clean up, call: • Environmental Health and Safety • Public Safety CUNY HazCom

  31. Spill Kits A spill kit should be available in all areas where chemicals are stored or used The spill kit should contain (at a minimum): • Gloves & Goggles • Absorbent / Neutralizer • Scoop / mini shovel • Bag / container Restock the spill kit as soon as possible whenever anything is used or removed from it CUNY HazCom

  32. Fire Extinguishers 4 Classes • Class A - paper, lumber, cardboard, plastics. • Class B - gasoline, kerosene, organic solvents. • Class C - energized electrical equipment including appliances, switches, panel boxes, power tools, hot plates and stirrers. • Class D – combustible/pyrophoric/organometallic metals, such as magnesium, sodium, and potassium. These materials burn at high temperatures and will react violently with water, air, and/or other chemicals. Handle with care!! CUNY HazCom

  33. Gasoline, propane, and solvents. Computers, fax machines, and copiers. Trash, paper, and cloth. CUNY HazCom

  34. Fire Extinguisher Use If you use a fire extinguisher to put out a small fire, remember: Pull the pin Aim at base of fire Squeeze the trigger Sweep from side to side CUNY HazCom

  35. CUNY HazCom

  36. Safety Showers • Know the location of the nearest safety shower in case of emergency • Make sure it’s accessible, in good working order, and that its inspection is up-to-date CUNY HazCom

  37. Eye Wash • Know the location of the nearest eye wash in case a chemical comes in contact with your eye • Flush your eye(s) for at least 15 minutes • Eye wash stations should be flushed weekly CUNY HazCom

  38. Material Safety Data Sheets(MSDS) CUNY HazCom

  39. Where can you find an MSDS for a chemical? • An MSDS MUST be available anywhere a chemical is used or stored • Each person must know how and where to find an MSDS in the immediate area • An MSDS should be included with the purchase of a chemical. Many are available online. • Ask EH&S if you have having difficulty locating an MSDS or getting one from a manufacturer CUNY HazCom

  40. Sections of MSDS • Product Identification / Ingredients • Hazards • First Aid • Fire Fighting • Release Measures • Handling / Storage • Personal Protection • Physical / Chemical Properties • Toxicology • Disposal / Transport Information CUNY HazCom

  41. Product Identification / Ingredients • Chemical name, trade name, synonyms • CAS (Chemical Abstract Service) Number • Molecular Formula / Molecular Weight • Ingredients and Percentages CUNY HazCom

  42. Hazards • Warning Phrases • Danger! Flammable! Corrosive! • NFPA Ratings (0-4) for Health, Flammability, Reactivity, Special/Other • Potential Health Effects • Inhalation, skin contact, ingestion, chronic exposure CUNY HazCom

  43. First Aid • Information on what do in case of an exposure by • Inhalation • Ingestion • Skin Contact • Eye Contact CUNY HazCom

  44. Fire Fighting Information • Flash point • Auto ignition temperature • Type of fire extinguisher to use CUNY HazCom

  45. Release Measures • Measures to take if this material is released to the environment • Reportable Quantities • Coast Guard National Response Center (NRC) 1-800-424-8802 CUNY HazCom

  46. Handling/Storage • Ideal/preferred storage conditions (humidity and temperature) • Ventilation • Store away from incompatibles • Flammables / Corrosives cabinets CUNY HazCom

  47. PPE • Recommendations for types of gloves to be used (nitrile, latex, butyl) based on the specific chemical’s properties • Recommendations for respirator type and cartridge selection • Additional PPE (glasses, apron, shoes, etc.) • Exposure Limits • Permissible exposure limit (PEL) • Short term exposure limit (STEL) • Threshold Limit Value (TLV) CUNY HazCom
