The Emergency Response Guidebook (ERG) 7 was developed jointly by the U.S. Department of Transportation, Transport Canada, and the Secretariat of Communications and Transportation of Mexico (SCT) for use by fire fighters, police, and other emergency services personnel who may be the first to arrive at the scene of a transportation incident involving hazardous materials. The ERG was developed to 1) aid first responders in quickly identifying the specific or generic hazards of the material(s) involved in the incident, and 2) protect themselves as well as the general public during the initial response phase of the incident. For the purposes of the guidebook, the “initial response phase” is that period following arrival at the scene of an incident during which the presence and/or identification of hazardous materials is confirmed, protective actions and area requirement are initiated, and assistance of qualified personnel is requested. It is not intended to provide information on the physical or chemical properties of dangerous goods. The ERG incorporates dangerous goods lists from the most recent United Nations (UN) Recommendations as well as from other international and national regulations. Show The ERG identifies small spills as those that involve quantities that are less than 200 liters for liquids and less than 300 kilograms for solids; and large spills than involve quantities that are greater than 200 liters and greater than 300 kilograms of solids. The guidebook then further subdivides an incident into daytime and nighttime situations. Basics of the ERGInformation on how to use the ERG and other supporting information including definitions and emergency response telephone numbers can be found in the white pages of the ERG. Then, the Guidebook is divided into four color-coded sections: yellow, blue, orange and green. The yellow-bordered pages index the list of dangerous goods in numerical order of 4-digit ID numbers. The user is provided with a corresponding guide number that references safety information in the orange section. The blue-bordered pages are similar to the yellow section, but they provide an index list of hazardous materials in alphabetical order by name. Again, the user is provided with a corresponding guide number that references safety information in the orange section. The user is also provided with the UN number that corresponds with the name of the hazardous material. The orange-bordered pages or orange guide is the most important section of the guidebook as this is where all the safety recommendations reside. The orange guide comprises a total of 62 individual guides, each providing safety recommendations and emergency response information to protect yourself and the public. Recommendations include potential hazards, public safety, and emergency response actions. The green-bordered pages recommend initial isolation or protective action distances for hazardous material spills that involve Toxic by Inhalation (TIH) material, chemical warfare agents, or produce TIH material when coming into contact with water. These distances differ based on whether the incident occurred during the day or at night. They also vary based on the size of the spill. In both the yellow-bordered and blue-bordered sections, an entry highlighted in green means an evacuation area needs to be established and the user should first refer to the green-bordered section. Intended Use of the ERGThe ERG was developed to assist responders that may be first to arrive at the scene of a transportation incident involving hazardous materials. For non-transportation related hazardous materials incidents, emergency responders should seek additional information to assist with interpretation of chemical properties and spill dynamics. This information may be acquired by contacting the manufacturer of the product, or by consulting an outside source. Clarification of CoverageThe ERG was developed to assist responders that may be first to arrive at the scene of a transportation incident involving hazardous materials. For non-transportation related hazardous materials incidents, emergency responders should seek additional information to assist with interpretation of chemical properties and spill dynamics. This information may be acquired by contacting the manufacturer of the product, or by consulting an outside source. Companion ResourcesNumerous references have been developed over the years to assist personnel responding to a hazardous materials spill. Many of these references present important information on strategies and techniques for hazardous materials spills and incident clearance. In addition, many references have been computerized to improve the mitigation time of responders. Potential references that may be used in conjunction with the ERG include:

 2020 ERG AuthorUnited States Department of TransportationSubjectHazardous MaterialsPublishedEvery four yearsPublication date 08/2020Websitewww.phmsa.dot.govThe Emergency Response Guidebook: A Guidebook for First Responders During the Initial Phase of a Dangerous Goods/Hazardous Materials Transportation Incident (ERG) is used by emergency response personnel (such as firefighters, paramedics and police officers) in Canada, Mexico, and the United States when responding to a transportation emergency involving hazardous materials. First responders in Argentina, Brazil, and Colombia have recently begun using the ERG as well. It is produced by the United States Department of Transportation, Transport Canada, and the Secretariat of Communications and Transportation (Mexico). The principal authors of the ERG are Transport Canada's Michel Cloutier and U.S. DOT's George Cushmac.[1] Guidebook ContentsThe ERG is primarily applicable for hazardous materials transported by highway and railway, but also is applicable for materials transported by air or waterway, as well as by pipeline. It was first issued by the US Department of Transportation in 1973, but later became a joint publication of the Department of Transportation (US DOT), Transport Canada (TC), and the Secretariat of Communications and Transportation (SCT) of Mexico, with collaboration with the Chemistry Information Center for Emergencies (CIQUIME) of Argentina. The ERG is issued every 4 years, with editions now being published in Spanish (Guía de Respuesta en Caso de Emergencia) and French. In 1996 it was published as the North American Emergency Response Guidebook, but by the next publication in 2000 "North American" was removed due to its use by several South American countries). The ERG "is primarily a guide to aid first responders in quickly identifying the specific or generic hazards of the material(s) involved in the incident, and protecting themselves and the general public during the initial response phase of the incident"[2] and should only be used for the "initial response phase" ("that period following arrival at the scene of an incident during which the presence and/or identification of dangerous goods is confirmed, protective actions and area securement are initiated, and assistance of qualified personnel is requested.") of an incident . It is divided into six color-coded sections (white [uncolored], yellow, blue, orange, green, and a second white [uncolored]). The ERG includes 62 "Guides" (found in the Orange Section) that identify the primary hazards associated with the applicable general category of hazardous material and general guidance on how to respond to incidents involving that general category of hazardous material. The primary purpose of ERG is to direct the emergency responders to the most appropriate of these guides, based on the incident. The ERG also provides guidance regarding recommended evacuation distances, if applicable, in the Green Section. SectionsWhite Section (front)The first section, with white page (uncolored) borders, provides the following:
Yellow SectionThe second section, with yellow page borders, references the material in order of its assigned 4-digit ID number/UN/NA number (which is often placarded with the other hazardous materials placards) and identifies the appropriate guide number to reference in the Orange Section). Items highlighted in green in this section will have evacuation distances included in the Green Section. Blue SectionThe third section, with blue page borders, references the material in alphabetical order of its name and identifies the appropriate guide number to reference in the Orange Section). Items highlighted in green in this section will also have evacuation distances included in the Green Section. Orange SectionThe fourth section, with orange page borders, includes the actual response guides. Each of the 62 guides provides safety recommendations and directions on how to proceed during the initial response phase (first thirty minutes) of the incident. It includes "health" and "fire or explosion" potential hazard information (with the more dangerous hazard listed first). For example, "the material gives off irritating vapors, easily ignited by heat, reactive with water"; "highly toxic, may be fatal if inhaled, swallowed or absorbed through skin"; etc. Next this section includes information for responders on appropriate protective clothing and possible evacuation information for either spill or fire is given. It also includes information on fighting fires (example, do not apply water to sodium), warnings for spills or leaks, and special directions for first aid (example, not to give mouth-to-mouth resuscitation if the materials are toxic). In the event of an unknown material, Guide #111 should be followed until more information becomes available. Green SectionThe fifth section, with green page borders, suggests initial evacuation or shelter in place distances (protective action distances) for spills of materials that are Toxic-by-Inhalation (TIH). These distances vary based on the size of the spill (small or large) and whether the incident occurs during the day or at night. Only materials that were highlighted in green in the Yellow and Blue Sections are included in the Green Section. This section also includes information regarding toxic gases that are produced when certain materials are spilled in water (as identified previously in this section). Finally, this section includes some very specific evacuation details for six common materials. White Section (back)The sixth section, with white page (uncolored) borders, provides the following:
