Study Notes

Hazmat Incident Information Sources

  • Observations, reports from bystanders, and victim accounts provide vital information during a Hazmat incident.
  • Look for labels, placards, shipping papers, and Safety Data Sheets (SDS) for hazard specifics.
  • Emergency response vehicles must carry the most recent edition of the DOT Emergency Response Guidebook (ERG) for reference, available as a mobile app.

Emergency Response Guidebook (ERG)

  • ERG contains critical information on substance properties and hazard identification.
  • It includes placard meanings and recommended isolation distances.
  • Nine recognized chemical families are classified as DOT Class 1 through 9:
    • Class 1: Explosives
    • Class 2: Gases
    • Class 3: Flammable and combustible liquids
    • Class 4: Flammable solids, spontaneously combustible materials, water-reactive substances
    • Class 5: Oxidizing substances, organic peroxides
    • Class 6: Toxic and infectious substances
    • Class 7: Radioactive materials
    • Class 8: Corrosive substances
    • Class 9: Miscellaneous hazardous materials

Hazard Marking Systems

  • The USD marking system employs labels, placards, and markings for Hazmat transport in the U.S. and Canada.
  • Placards are diamond-shaped indicators placed on vehicles to represent broad hazard classes.
  • The United Nations and North American coding system employs four-digit numbers for specific Hazmat identification.
  • Labels are smaller than placards and indicate hazards specific to smaller packages.

Minimum Marking Requirements

  • Not all chemical shipments require placarding; specific quantities of Hazmat must be present.

Documentation for Hazard Identification

  • Bill of lading or freight bill carried by the truck driver provides transport details.
  • Waybill or manifest used for rail transport outlines Hazmat specifics.
  • Dangerous cargo manifest and air bills provide information for maritime and air transport, respectively.

Additional Resources

  • Dispatchers can gather information from sources like KEMRA, which has a comprehensive chemical database.
  • Essential information for KEMRA includes:
    • Chemical name, caller identification, incident location, shipper/manufacturer info, container type, carrier name, recipient details, local conditions, and situation description.

Fixed Facility Marking Systems

  • NFPA 704 system features a placard with four diamonds indicating specific hazards.
    • Red: Fire hazard level
    • Blue: Health hazard level
    • White: Special information
    • Yellow: Reactivity hazard level
  • Hazard levels rated from 0 (no hazard) to 4 (high risk).

Safety Data Sheets (SDS)

  • Obtain SDS from permanent facilities for detailed hazard information.
  • SDS provides chemical composition, potential hazards, first aid measures, and safe handling instructions.

Hazmat Incident Information Sources

  • Observations and victim accounts are crucial for assessing Hazmat incidents.
  • Important documents include labels, placards, shipping papers, and Safety Data Sheets (SDS) for understanding hazards.
  • Emergency response vehicles should carry the latest DOT Emergency Response Guidebook (ERG) for immediate guidance; available as a mobile app.

Emergency Response Guidebook (ERG)

  • ERG provides essential information on hazardous substance properties and identification.
  • It contains meanings of placards and guidelines for recommended isolation distances.
  • Classifications under DOT include:
    • Class 1: Explosives
    • Class 2: Gases
    • Class 3: Flammable and combustible liquids
    • Class 4: Flammable solids, spontaneously combustible materials, water-reactive substances
    • Class 5: Oxidizing substances, organic peroxides
    • Class 6: Toxic and infectious substances
    • Class 7: Radioactive materials
    • Class 8: Corrosive substances
    • Class 9: Miscellaneous hazardous materials

Hazard Marking Systems

  • The USD marking system uses labels, placards, and markings for Hazmat transport in the U.S. and Canada.
  • Diamond-shaped placards on vehicles indicate broad hazard classes.
  • The UN and North American coding system uses four-digit numbers for precise Hazmat identification.
  • Labels convey specific hazards associated with smaller packages.

Minimum Marking Requirements

  • Not all chemical shipments must be placarded; only those above specific Hazmat quantity thresholds require marking.

Documentation for Hazard Identification

  • The bill of lading or freight bill carried by truck drivers details transport specifics.
  • For rail transport, a waybill or manifest provides Hazmat information.
  • Dangerous cargo manifests and air bills convey information for maritime and air transport respectively.

Additional Resources

  • Dispatchers can utilize KEMRA, a chemical database, for gathering information.
  • Key details in KEMRA include chemical name, incident location, type of container, carrier name, and situation description.

Fixed Facility Marking Systems

  • NFPA 704 system features a placard with colored diamonds indicating specific hazard types:
    • Red signifies fire hazard level.
    • Blue indicates health hazard level.
    • Yellow signifies reactivity hazard level.
    • White represents special hazards.
  • Hazards rated from 0 (no hazard) to 4 (high risk).

Safety Data Sheets (SDS)

  • SDS must be obtained from facilities for comprehensive hazard details.
  • SDS includes chemical composition, potential hazards, first aid instructions, and handling guidelines.
