The Emergency Response Guidebook 2012 (ERG2012) Training Package is available in HTML as well as in Microsoft Office Power Point Format. The Emergency Response Guidebook 2012 (ERG2012) 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. The different placards used in the transport of dangerous goods are found on pages 6 and 7 of the ERG2012. Caution: The recommended guides should be considered as a last resort if the material cannot be identified by any other means.
Pages 8 and 9 of the ERG2012 depict the general shapes of railcars and road trailers used in the transportation of dangerous goods.
The ID Number is followed by the 3-digit guide number (ORANGE section) to refer to, as well as the name of material. Please note that some substances are highlighted in GREEN and should be treated specifically. Follow this link to access the Identification Number Index in the online Emergency Response Guidebook 2012. The name of the material is followed by the 3-digit guide number (ORANGE section) to refer to, as well as the ID Number.
Please note that some substances are highlighted in GREEN and thus will have to be treated specifically. Follow this link to access the Names of Material Index in the online Emergency Response Guidebook 2012.
This polymerization will produce heat and high pressure buildup in containers which may explode or rupture.
This section contains all the guides needed for the initial response phase of an incident involving dangerous goods.
The subsection Fire or Explosion or Health will appear first depending on the primary hazards of the type of substance. A suggested isolation area, as an immediate precautionary measure, irrespectively of the quantity involved. The reference to Table 1 - Initial Isolation and Protective Action Distances (GREEN section).
The distances show the areas likely to be affected during the first 30 minutes after the materials are spilled, and this distance could increase with time. The responders must choose a protective actions: evacuation, shelter in place or a combination of both (see page 288 of the ERG2012).
For any intermediate quantity, the distances would need to be estimated between the distances provided for small and large spills. Defines an area SURROUNDING the incident in which persons may be exposed to dangerous (upwind) and life threatening (downwind) concentrations of material.
The shape of the area in which protective should be taken actions (the Protective Action Zone) is shown in the figure below.
A list of materials which produce large amount of Toxic Inhalation Hazard (TIH) gases when spilled in water and identifies the TIH gases produced.
These Water Reactive materials are easily identified in Table 1 as their name is immediately followed by (when spilled in water). The materials are presented in alphabetical order and provide initial isolation and protective action distances for large spills (more than 208 litres or 55 US gallons) involving different container types (therefore different volume capacities) for day time and night time situations and different wind speeds. The following table gives a summary of tank properties, critical times, critical distances and cooling water flow rates for various tank sizes that may be involved in a BLEVE. An improvised explosive device is a bomb that is manufactured from commercial, military or homemade explosives. A Safe Standoff Distance Chart for various threats when improvised explosive device are involved is found on page 372 of the ERG2012.
Page 386 of the ERG2012 provides the telephone numbers of the provincial agencies that must1 be contacted for any incident involving dangerous goods.
Additionally, CANUTEC may2 be contacted in order to get more detailed technical information on the dangerous goods involved.
CANUTEC is the Canadian Transport Emergency Centre and is operated by the Transport Dangerous Goods Directorate of Transport Canada. Read carefully all the information provided in the ORANGE Guide and use jointly the GREEN Section if the substance is highlighted.


A tanker truck carrying the following product rolled over and is leaking from the top hatch. As an immediate precautionary measure, isolate spill or leak area for at least 50 metres in all directions. In the BLUE-bordered pages, explosives are not highlighted substances, therefore the GREEN section does not apply.
A rail car is leaking during the day, at a well-known facility in your area, where chlorine cars are handled. The Guide 124 indicates that this product is toxic and may be fatal if inhaled or absorbed through the skin.
Table 3 provides initial isolation and protective action distances for large spills (more than 208 litres or 55 US gallons) involving different container types (therefore different volume capacities) for day time and night time situations and different wind speeds. In this case, for a rail car, the initial isolation distance suggested in Table 3 is 1000 metres. Since there is a spill, the initial isolation and protective action distances must be taken from Table 1. In Table 1, the description “when spilled in water” indicates a substance is water-reactive. In this case, Table 2 must also be consulted where the TIH gases produced are listed, for each water-reactive substance. When searching for hydrogen cyanide in the BLUE section, there is a reference to Guide 117, which correspond to Gases – Toxic – Flammable (Extreme Hazard). Additionally, the protective action distances for day and night will have to be taken from the Table 1 and adapted. The Department of Transportation (DOT) Emergency Response Guidebook, ERG known as the "DOT Book" or the "Orange Book", is published almost every three years and covers Canada, Mexico and the USA.
The ERG is available as online reference and download, and also as an app that you can access on your phone.
If the chemical entry is highlighted in either the blue or yellow sections, it presents a toxic inhalation hazard (TIH) or a water reactive hazard. White pages contain general information about the guide, emergency contact information, guides for explosives, and visual identification references.
If neither the UNID or the chemical name are available, you will need to refer to the white section of the ERG.
Yellow Pages list the materials in numerical order by their UN ID number and provides the specific guide number for the orange section. Blue Pages list the materials in alphabetical order by their name and provides the specific guide number for the orange section.
Orange Pages are the initial action guides organized numerically by the three-digit guide number. Under Potential Hazards you will find information describing potential fire and explosion hazards and health effects upon exposure, with the highest potential hazards being listed first. The Public Safety section provides directions for taking immediate public safety and initial isolation measures. Green Pages provide information on initial isolation and protective distances, and also water reactive materials, which produce toxic gasses. Assuming the UN ID is 2901, or Bromine Chloride, you would have the exact guide number for the orange section, but you would also notice that this chemical is highlighted in green. Table 1 indicates an initial isolation distance of 400 meters (1250 feet) in all directions for a large spill.
Along with the ERG, the National Institute for Occupational Safety and Health is another great reference put out with the help of the CDC and is available online or by mail order.
116P), the material may undergo violent polymerization if subjected to heat or contamination. An asterisk (*) next to the ID number indicates to consult Table 3 for more information. This will result in a higher toxic concentration in the air and consequently, necessitate a greater Protective Action Zone. Catastrophic failure of the vessel is followed by the explosive release of boiling liquid and expanding vapour.
It is staffed by professional scientists experienced and trained in interpreting technical information and providing emergency response advice.


1689 – sodium cyanide) and not for the generated TIH gas (hydrogen cyanide) indicated in Table 2. It is a guide to aid emergency responders in quickly identifying the specific or generic hazards of materials involved in an emergency incident. The letter P following the Guide number in the yellow-bordered and blue-bordered pages identifies those materials that present a polymerization hazard under certain conditions. GO DIRECTLY TO THE GREEN SECTION AND START RECOMMENDED EVACUATIONS BEFORE TAKING ANY OTHER ACTION. These references include the Table of Placards, Rail Car, and Road Trailer identification charts.
This section should be the first one referenced on the guide page, allowing responders to make decisions regarding the protection of the emergency response team as well as the surrounding population.
It also describes the type of protective clothing and respiratory protection that should be worn by responders. You arrive at an accident where a trailer is spilling large quantities of a reddish yellow fluid. Best-case scenario you can see the UN ID number (yellow section) or you are provided the specific chemical name (blue section).
You can use all of the appropriate sections to determine the best actions to be taken with the featured chemicals. Generally involves a single small package, a small cylinder, or a small leak from a large package. Generally involves a spill from a large package, or multiple spills from many small packages. This section is made up of a table of initial isolation and protective action distances that should be referenced before you turn to the orange pages.
While these sections will help you with initial isolation distances they should not be relied on. Lastly, it lists preliminary evacuation distances for small and large spills and fire situations. Either would allow you to find the correct protective actions in the orange and green sections.
Once youOve transmitted emergency information to the proper authorities you will need to take actions to protect yourself and others by controlling the incident. Isolating, denying entry, and protecting people downwind for the appropriate distances should prevent further injuries due to exposure.
Responders should proceed initially by requesting local, state, and then federal assistance. DonOt try to run your scene with this book; you must get more detailed information on the chemical. The initial isolation distance is a distance within which all persons should be considered for evacuation in all directions from the actual source. You should get more specific information identifying the specific material as soon as possible. Responders must learn how to use the ERG and be familiar with the guide prior to an incident.
Protective action distances include the area immediately adjacent to and downwind from the initial isolation zone. Remember that the smallest initial isolation distance for any chemical listed in the green section of the ERG is 100 feet (30 meters).
The ERG provides a large amount of background material that could not be read during an emergency, like the list of the nine hazard classes used by the DOT. This area is in imminent danger of being contaminated by airborne vapors within thirty minutes of material release. It is important to be familiar with the abbreviations used in the ERG so you can reference it quickly and efficiently.
