  1. Chapter 26 Hazardous Materials: Information Resources

  2. Introduction • Chemical information available through variety of sources • Shipper and facility required to maintain certain documents • Know what information is available • Understand how to interpret the information in common sources

  3. Emergency Response Guidebook • DOT makes one copy for every emergency response apparatus in the country • Referred to as the DOT book or the orange book • Published about every three years • Provides information regarding potential hazards • One of the only books that provides specific evacuation recommendations

  4. Figure 26-1 The DOT Emergency Response Guidebook should be found in every emergency vehicle in the United States. It provides chemical emergency response information that is valuable to the first responder.

  5. Emergency Response Guidebook (cont'd.) • Consists of these major sections: • Placard information • ADR/RID marking system information • Listing by DOT identification number • Alphabetical listing by shipping name • Response guides • Table of initial isolation and protective action distances • List of dangerous water-reactive materials

  6. Figure 26-13 A large spill of ethyl isocyanate (ID 2481) is listed as having an isolation distance of 1,700 feet in all directions. In such a case, responders need to protect those persons downwind for 7+ miles.

  7. Emergency Response Guidebook (cont'd.) • Provides contact numbers for agencies in the U.S., Canada, and Mexico • Yellow section: numerical listing by DOT ID • Blue section: mirrors yellow, but alphabetical by shipping name • Orange section: 61 guides for more than 4000 chemicals • Three sections: potential hazards, public safety, emergency response

  8. Emergency Response Guidebook (cont'd.) • Emergency response section hints: • Fight fire from a distance using unstaffed monitors • Withdraw immediately if sound level from venting devices rises • Cool containers with flooding quantities of water until well after the fire is out • First aid section: basic medical treatment

  9. Using the DOT Emergency Response Guidebook • Resist rushing in • Approach incidents from an uphill/upwind direction • Identify the material by finding one of the following: • Four digit ID on placard/ID panel • Four digit ID number on shipping document or package • Name of material on shipping document, placard, or package

  10. Using the DOT Emergency Response Guidebook (cont’d.) • Look up the three digit guide number of the material in either: • ID number index • Name of the material index • Turn to the numbered guide

  11. Figure 26-14 Software is available that can plot toxic gas cloud plumes, which can help determine isolation areas and guide evacuation decisions.

  12. Material Safety Data Sheets • Result of the hazard communication standard • Employers with larger than “household quantities” must create MSDS • Required to have a variety of information • Intent is to protect employees working at the facility

  13. Material Safety Data Sheets (cont'd.) • Quality of information varies from MSDS to MSDS • Typical MSDS provides a worst-case scenario • Firefighter should rely more on technical information on MSDS • MSDS has remained the same since inception

  14. Using the MSDS Wisely • Always use more than one source of information • Determine action plan using MSDS • Determine chemical threat • Don appropriate level PPE • If material has released, follow evacuation procedure and secure building • Determine which extinguishing agents are required

  15. Accidents and How the MSDS Relates • Chemical information on MSDS usually presents hazards associated with particular product • Once product is placed in a process some factors may change • Increase, decrease, or elimination of hazards • Factors include: • Reactions with other chemicals • Changes in temperature, pressure, or physical characteristics

  16. MSDS in the Workplace • Employers to provide employees with an MSDS for every hazardous chemical • An MSDS provides information on physical/chemical characteristics and first-aid procedures • Example: Figure 26-16 in text

  17. MSDS in the Workplace (cont’d.) • Can be insufficient depending on provider • Vagueness • Technical jargon • Understandability • Product versus process • Missing information

  18. Shipping Papers • Shipping papers generally provide the following information: • Shipping company • Destination of packages • Emergency contact information • Number and weight of packages • Proper shipping name of materials • Hazard class of materials • Special notation for hazardous materials

  19. Mode of Transportation • Shipping papers are also called a bill of lading • Papers should be close to the driver • On tank trucks a duplicate set is located in a tube attached near landing gear • Hazardous materials are sometimes color coded • For rail, shipping papers are called consist or waybill and placed in control of the engineer

  20. Mode of Transportation (cont'd.) • Most railcars are identified well • Standard Transportation Commodity Code (STCC) • Seven-digit number • Number beginning with “49” are hazardous • On a ship, papers are called dangerous cargo manifest (DCM) and placed in control of the captain • In air, shipping paper are called Air Bills and placed in control of the captain

  21. Facility Documents • Those with an MSDS requirement: • Tier 2 form • Site plan • Those with extremely hazardous substances (EHS) • Emergency plan • Many facilities leave MSDS binder at gate with security guard • SARA reports updated annually and should be reviewed by responders

  22. Computer Resources • Chemical information texts are also available on CD-ROM • Use of Computer-Aided Management for Emergency Operations (CAMEO) program • Easily accessed • Can be used by first responders • Ability to provide vapor cloud model • MSDS electronically • CDs, Internet

  23. Figure 26-17 A toxic gas cloud projection model known as Aloha is part of the hazardous materials software program CAMEO.

  24. Chemtrec • Chemical Transportation Emergency Center • Information service provided by American Chemistry Council • Chemtrec service • Chemtrec is well connected • Chemtrec does not make regulatory notifications

  25. Chemtrec (cont'd.) • Responder should have the following information when calling Chemtrec: • Caller’s name and phone number • Name of the shipper or manufacturer • Shipping paper information • Canadian equivalent is called CANUTEC • Mexican equivalent is SETIQ • All three emergency contact numbers provided in DOT ERG

  26. Reference and Information Texts • Many texts available from a variety of sources • Every apparatus should carry several reference sources • DOT ERG is fairly easy to use • Reference texts slanted toward group that develops the text • No one book is the “only” book to use

  27. Figure 26-18 Several common hazardous materials reference sources, including the NIOSH pocket guide and the Sax guide to Dangerous Properties to Industrial Materials.

  28. Industrial Technical Assistance • Each community usually has a technical specialist in a given field • Many areas of the country have industrial mutual aid groups designed to assist each other • Each industrial facility usually has a person responsible for safety and health • Many facilities have industrial hygienists

  29. Lessons Learned • Obtain as much information as possible • Information combined with reference sources can provide useful data • Obtain as much information as possible prior to arriving on scene • Responders should not take risks attempting to get this information
