  26. Combustible liquid Compressed gas Explosive Flammable Organic peroxide Oxidizer Pyrophoric Unstable (reactive) Water-reactive Physical hazards include any chemical that is: 2b

  27. Hazard communication program • Must comply with Hazard Communication Standard - 29 CFR 1910.1200 3a

  28. Hazard communication program Written program must include: • a list of hazardous chemicals present in the workplace • MSDS • labeling system information 3b

  29. Hazard communication program Written program must include: • employee training information • information regarding nonroutine hazards • methods of informing employers of other workers (contractors) 3c

  30. Hazard communication program • Written program does not have to be accessible to every work area and every work shift • Written program is available to workers upon request 3d

  31. Accessing Hazcom documents • Workers must know how to obtain, and the location of: • the written Hazcom program • lists of hazardous chemicals • MSDSs 4a

  32. Protective measures • Work practices • Engineering controls • Personal protective equipment 5a

  33. Material safety data sheets • Primary tool for getting detailed chemical information • Must be readily available 6a

  34. Material safety data sheets include • Chemical identity • Physical and chemical characteristics • Physical and health hazards • Primary routes of entry 6b

  35. Material safety data sheets include • PEL, TLV, other exposure limits • Whether it is a carcinogen • Precautions for safe handling/use • Recommended engineering controls 6c

  36. Material safety data sheets include • Emergency first aid procedures • Date of preparation • Name, address, phone number of manufacturer, importer, responsible party 6d

  37. Material safety data sheets • MSDSs may contain recommendations from ANSI 6e

  38. Material safety data sheets • MSDSs also provide information regarding: • signs and symptoms of exposure • personal protective equipment • spill and leak clean-up • labeling information 6f

  39. Each chemical must have an MSDS • MSDS must be available to downstream employers from: • chemical manufacturers • importers • distributors 7a

  40. Labeling requirements • Labels warn of potential dangers • Labels are not intended to be the sole source of information 7a

  41. Labeling requirements • Labels serve as an immediate warning • Labels must be keyed to MSDSs 7b

  42. Labeling requirements • Labels must contain: • the identity of the hazardous chemical • appropriate hazard warnings • the name, address of the chemical manufacturer, importer, other responsible party 7c

  43. Labeling requirements • Ensure that labels do not come off, become smudged or unreadable • For hard-to-label containers, use: • signs or placards • process sheets, or batch tickets 7d

  44. Labeling requirements • Be able to quickly identify the general hazard of any material: • NFPA system identifies: • Health hazards • Flammability hazards • Reactivity hazards • Special hazards 7e

  45. Labeling requirements • Be able to quickly identify the general hazard of any material: • HMIS system identifies • Health hazards • Flammability hazards • Physical hazards 7f

  46. Hazards of nonroutine tasks • Know what chemicals you work with and their hazards • Know the contents of pipes 8a
