1 The 2012 Emergency Response Guidebook (ERG2012) Developed jointly by:  Transport Canada (TC)  The U.S. Department of Transportation (DOT)  The Secretariat of Transport and Communications of Mexico (SCT) Used by fire fighters, police, and other emergency services personnel who may be the first to arrive at the scene of a transportation incident involving dangerous goods.

2 Application of the ERG 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. Assists first responders in making initial decisions upon arriving at the scene of a dangerous goods incident.

3 Limitations of the ERG It should not be considered as a substitute for emergency response training, knowledge or sound judgment. Does not address all possible circumstances that may be associated with a dangerous goods incident. Designed for use at a dangerous goods incident occurring on a highway or railroad. Limited value in its application at fixed facility locations.

4 Listed Materials Incorporates dangerous goods lists from the most recent United Nations Recommendations as well as from other international and national regulations.

5 Explosives Explosives are not listed individually by either proper shipping name or ID Number. They do, however, appear under the general heading "Explosives" on the first page of the ID Number index (yellow-bordered pages) and alphabetically in the Name of Material index (blue- bordered pages). The letter "P" following the guide number in the yellow-bordered and blue-bordered pages identifies those materials which present a polymerization hazard under certain conditions,

6 Transportation of Hazardous Materials Response First responders at the scene of a dangerous goods incident, should seek additional specific information about any material in question as soon as possible. The information received by:  Contacting the appropriate emergency response agency  Contacting the emergency response number on the shipping document  Consulting the information on or accompanying the shipping document

7 Table of Placards Pages 6 and 7 of the ERG depict the different placards used in the transport of dangerous goods. ORANGE Each group of placards is associated to a 3- digit guide number (ORANGE Section).

8

9 Rail Car and Road Trailer ID Charts Pages 8 and 9 depict the general shapes of railcars and road trailers used in the transportation of dangerous goods. ORANGE Each shape is associated to a 3-digit guide number (ORANGE Section).

10

11 ERG Format The book is divided into sections by the page border colors  Yellow  Blue  Orange  Green

12 Yellow-bordered pages Index list of dangerous goods in numerical order of ID number. This section quickly identifies the guide to be consulted from the ID Number of the material involved. YELLOW Some substances are highlighted in YELLOW and should be treated specifically

13

14 Blue-bordered pages Index list of dangerous goods in alphabetical order of material name. This section quickly identifies the guide to be consulted from the name of the material involved. BLUE Some substances are highlighted in BLUE and thus will have to be treated specifically.

15

16 Letter “P” Note regarding the YELLOW and BLUE bordered Sections If the guide number is supplemented with the letter “P”, it indicates that the material may undergo explosive polymerization if subjected to heat or contamination. Polymerization generates heat and pressure build-up inside containers, which may explode.

17 Distances for Yellow and Blue Pages That are Not Highlighted In the YELLOW or BLUE Sections, if the substance is not highlighted:  Use the suggested distances provided in the ORANGE Section, i.e.:  Isolate the area in all directions, as an immediate precautionary measure, to the minimum distance suggested under Public Safety, and increase the zone if needed;  Consider the evacuation distances suggested under Evacuation – Spill / Fire.

18 Distances for Yellow and Blue Pages That Are Highlighted For small and large spills use the Initial Isolation and Protective Action Distances suggested in the GREEN Section. In case of fire, use the distances provided in the ORANGE Guide, under Evacuation – Fire.

19 Orange-bordered pages Provides all safety recommendations Comprised a total of 62 individual guides, presented in a two-page format Each guide provides safety recommendations and emergency response information to protect yourself and the public The left hand page provides safety related information whereas the right hand page provides emergency response guidance and activities for fire situations, spill or leak incidents and first aid.

20 Orange Section Guides

21 Under Public Safety:  A suggested isolation area, as an immediate precautionary measure, irrespectively of the quantity involved. Under Evacuation:  A suggested evacuation perimeter for spill and fire situations AND/OR  The reference to the Table of Initial Isolation and Protective Action Distances (GREEN Section).

22 ERG 2012 Notes regarding the ORANGE Guides and the highlighted / non-highlighted substances  Each Guide covers a range of products, which present similar hazards;  Some specific substances (highlighted in the YELLOW and BLUE-bordered pages) must be dealt using simultaneously the ORANGE and GREEN Sections;  The GREEN Section indicates the specific distances to be used for each product;

23 Green-bordered pages Contains a table which lists, by ID number, TIH materials, including certain chemical warfare agents, and water-reactive materials which produce toxic gases upon contact with water. The table provides two different types of recommended safe distances which are "Initial isolation distances" and "Protective action distances".

24 Green Table Information The table provides distances for both small (approximately 200 liters or less) and large spills (more than 200 liters) for all highlighted materials. The list is further subdivided into daytime and nighttime situations.  Due to varying atmospheric conditions which greatly affect the size of the hazardous area.

25 Green Table Information Toxic by inhalation (TIH) Chemical Warfare Agents and Substances which produce toxic gases upon contact with water

26 Initial Isolation Zones 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. Defines an area SURROUNDING the incident in which persons may be exposed to dangerous (upwind) and life threatening (downwind) concentrations of material.

27 Daytime Versus Nighttime The distances change from daytime to nighttime due to different mixing and dispersion conditions in the air. During the night, the air is generally calmer and this causes the chemical to disperse less and therefore create a toxicity zone which is greater than would usually occur during the day. During the day, the chemical is generally dispersed by a more active atmosphere. The chemical will be present in a larger area; however, the actual area where toxic levels are reached will be smaller (due to increased dispersion).  It is the quantity or concentration of the chemical vapor that poses problems.

28

29 Protective Action Zone  Defines an area DOWNWIND from the incident in which persons may become incapacitated and unable to take protective action and / or incur serious or irreversible health effects;  For practical purposes, the Protective Action Zone is a square, whose length and width are the same as the downwind distance shown in the Table (see drawing next page);  The Protective Actions are: evacuation, shelter in place or a combination of both.

32 NAERG Examples ORANGE Find the ORANGE-bordered Guide-pages using the information provided; ORANGEGREEN Identify the suggested distances / zones in the ORANGE and/or GREEN Sections; Describe the main characteristics and hazards of the substance.

33 Example 1  A 1000-litre tote container is leaking. 1824

34  ID No. is 1824; YELLOW Guide 154  The YELLOW-bordered pages indicate that the name of the product is Sodium hydroxide, solution or Caustic soda, solution and refers to Guide 154; GREEN  The substance is not highlighted; there is no need to use the GREEN Section; Guide 154  The Guide 154 corresponds to Substances - Toxic and/or Corrosive (Non- Combustible);  As an immediate precautionary measure, the Guide suggests to isolate the spill or leak area in all directions for at least 50 metres for liquids; 1824 Example 1

35 Guide 154  In Guide 154, under the Potential Hazards Section, the Health hazards precede the Fire or Explosion hazards;  This type of substance is toxic by inhalation / ingestion / skin contact;  The contact with molten substance may cause severe burns to skin and eyes;  Fire may produce irritating, corrosive and/or toxic gases;  This type of substance is not combustible.

36  A drum containing this substance is punctured and is leaking on the ground Example 2

37  The ID No. is 2692; YELLOW  The YELLOW-bordered pages indicate that this substance is called Boron tribromide; Guide 157  It refers to Guide 157 and is highlighted; Guide 157  The Guide 157 correspond to Substances – Toxic and/or Corrosive (Non-Combustible / Water-Sensitive); GREEN  Since the substance is highlighted and there is a spill situation, the GREEN Section must be used to determine the Initial Isolation and Protective Action Distances; GREEN  For this product, the GREEN Section presents 2 separate entries for ID No. 2692: the 1 st one applies when the product is spilled on the ground and the 2 nd one, when it is spilled in water; 2692 Example 2

38 GREEN  In this case, the product is spilled on the ground and the Initial Isolation Distance suggested in the GREEN Section is 30 metres in all directions for a small spill and 60 metres in all directions for a large spill; GREEN  Additionally, the Protective Action Distances for day and night will have to be taken from the GREEN Section; Guide 157  The Guide 157 indicates that this type of substance (Boron tribromide) is toxic and non- combustible, but a fire will produce irritating, corrosive and/or toxic gases Example 2
