  1. Hazard CommunicationGeneral

  2. Benefits of understanding chemical hazards Prevent injuries, deaths from: • Violent chemical reactions, fires, explosions • Burns, irritation, trouble breathing, nausea, diseases Timber Products Manufacturers Association

  3. Benefits of understanding chemical hazards Manufacturers, importers: • Classify chemical hazards • Provide labels, safety datasheets (SDSs) Timber Products Manufacturers Association

  4. Detecting hazardous chemicals • Air monitoring equipment • Appearance, odor • Physical, chemical characteristics • Unknown chemicals to be considered hazardous Timber Products Manufacturers Association

  5. Physical and health hazards • Chemical manufacturers or importers must classify chemicals according to the physical and health hazards • A chemical can have both physical and health hazards Timber Products Manufacturers Association

  6. Physical and health hazards • Hazard classifications have sub-categories • Warning statements, phrases, other label elements are specified after classification Timber Products Manufacturers Association

  7. Physical hazards: • Explosives • Flammable gases • Flammable aerosols • Flammable liquids • Flammable solids • Oxidizing liquids • Oxidizing solids • Oxidizing gases • Self-Reactive substances • Pyrophoric liquids • Pyrophoric solids • Self-heating substances • Organic peroxides • Corrosive to metals • Gases under pressure • Substances which, in contact with water emit flammable gases Timber Products Manufacturers Association

  8. Physical hazards • Pyrophoric gas - spontaneously ignites at 130°F or below • Combustible dust - build-up can ignite if suspended in air in confined area • Grains, sugar • Charcoal, soot • Chemicals (sulfur) • Metals (magnesium, aluminum) • Plastics, resins Timber Products Manufacturers Association

  9. Health hazards • Acutely toxicity • Skin corrosion or irritation • Serious eye damage or irritation • Respiratory or skin sensitization • Germ cell mutagen • Carcinogenicity • Reproductive toxin • Target organ systemic toxin • Single exposure • Repeated exposure • Aspiration hazard Timber Products Manufacturers Association

  10. Health hazards Simple asphyxiant - displaces oxygen in the air to create an oxygen-deficient atmosphere that can lead to unconsciousness, death Timber Products Manufacturers Association

  11. Health hazards Health effects: • Can occur rapidly after brief exposure (acute) • Long-term effects after prolonged, repeated exposure (chronic) Timber Products Manufacturers Association

  12. Hazards not otherwise classified (HNOC) • An adverse physical or health effect that does not meet the specified hazard classes • Belongs to a category that OSHA did not adopt from the United Nations’ Globally Harmonized System of Classification and Labeling of Chemicals (GHS) • An effect that falls below the cut-off value for a hazard class Timber Products Manufacturers Association

  13. Protective control measures • Engineering controls • Administrative, work practice controls Timber Products Manufacturers Association

  14. Protective control measures • Enclosing operations • Ventilation equipment • Substituting less hazardous chemicals • Safer chemical handling procedures Timber Products Manufacturers Association

  15. Personal protective equipment (PPE) • Used when hazards are not completely controlled or eliminated by other control measures • PPE selection based on hazard assessment and effectiveness of PPE Timber Products Manufacturers Association

  16. Personal protective equipment (PPE) • Chemical-resistant: • Goggles • Face shields • Gloves • Boots • Coveralls • Aprons • Respirators • Do not use damaged, malfunctioning PPE Timber Products Manufacturers Association

  17. Emergency procedures • Chemical emergencies can involve fires, explosions, burns, asphyxiations • Unknown chemicals are considered to be hazardous • Emergency responders manage: • Releases of unknown chemicals • Any potentially dangerous release • Others go to safe area, report emergency Timber Products Manufacturers Association

  18. First aid • First aid information is on the SDS • Report overexposures to any chemical • Get prompt first aid, medical attention Timber Products Manufacturers Association

  19. First aid Contact with corrosive, irritating chemicals: • Use emergency eyewash, showers • Flush eyes/skin with water Timber Products Manufacturers Association

  20. First aid Overexposure from breathing vapors, gases, aerosols, fumes, dust: • Move victim to safe area with fresh air • Get emergency medical assistance Timber Products Manufacturers Association

  21. First aid Ingesting chemicals: • Call poison control center, emergency medical responders • Have information from SDS available • Only induce vomiting or give water if advised by a medical provider Timber Products Manufacturers Association

  22. Written HazCom program OSHA’s HazCom standard includes requirements for: • Chemical classification • Safety data sheets (SDSs) • Labeling • Written HazCom program • Employee information, training • Provisions for trade secrets Timber Products Manufacturers Association

  23. Written HazCom program • Written HazCom program is not required if only handling unopened containers Timber Products Manufacturers Association

  24. Written HazCom program Written HazCom program: • Labels, warnings • Safety data sheets (SDSs) • Employee information, training • List of hazardous chemicals • How employees learn hazards of non-routine tasks • Hazards of chemicals in unlabeled pipes Timber Products Manufacturers Association

  25. Labeling overview • Labels warn of potential dangers • Labels are not intended to be the sole source of information • Labels serve as an immediate warning • Containers need labels • Pipes, fuel tanks, engines are not containers Timber Products Manufacturers Association

  26. Labeling overview While HazCom 2012 is phased in, you will still see labels meeting previous rule: • Identity of hazardous chemical • Appropriate hazard warnings • Name and address of manufacturer, importer, or other responsible party Timber Products Manufacturers Association

  27. Labeling - shipped containers • Product identifier (matches SDS and list) • Signal word (Danger = severe hazard; Warning = less severe) • Hazard statement (based on hazard class and category) • Pictogram (symbol to show hazard class) • Precautionary statement (safe use, storage) • Name, address, phone number of manufacturer, importer, or responsible party to contact for emergency information Timber Products Manufacturers Association

  28. Labeling - shipped containers Timber Products Manufacturers Association

  29. Labeling - shipped containers Timber Products Manufacturers Association

  30. Labeling - shipped containers Timber Products Manufacturers Association

  31. Labeling - shipped containers Timber Products Manufacturers Association

  32. Labeling - shipped containers OSHA-defined hazards - Simple asphyxiant: • No pictogram • Signal word = “WARNING” • Hazard statement = “May displace oxygen and cause rapid suffocation” Timber Products Manufacturers Association

  33. Labeling - shipped containers OSHA-defined hazards - Combustible dust: • No pictogram • Signal word = “WARNING” • Hazard statement = “May form combustible dust concentrations in air” Timber Products Manufacturers Association

  34. Labeling - shipped containers OSHA-defined hazards - Pyrophoric gas: • Flame pictogram • Signal word = “DANGER” • Hazard statement = “Catches fire spontaneously if exposed to air” Timber Products Manufacturers Association

  35. Labeling - in-house containers • Rely on labels on shipped containers • Re-label if label falls off • Re-label if label cannot be read Timber Products Manufacturers Association

  36. Labeling - in-house containers Transferring hazardous chemicals to another container: • Must label container if another person will use it • Must label container if it is available during another shift Timber Products Manufacturers Association

  37. Labeling - in-house containers Individual stationary containers (i.e., tanks) may use: • Signs • Placards • Batch tickets • Operating procedures These alternatives must provide the same information as would a label Timber Products Manufacturers Association

  38. Labeling - in-house containers Different system for in-house labels: • Product identifier • Words, pictures, symbols, or a combination of these, that provide at least general information on the hazards of the chemicals Timber Products Manufacturers Association

  40. Labeling - in-house containers HMIS system identifies: • Health hazards - Blue • Flammability hazards - Red • Physical hazards - Orange • Personal protection - White Hazard severity (0 to 4): • 0 = minimal • 1 = slight • 2 = moderate • 3 = serious • 4 = severe Timber Products Manufacturers Association
