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.

- 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.
