  railcars and road trailers used in the
  transportation of dangerous goods.

• 4) The YELLOW Section
• In this section, the substances are listed in
  numerical order of their 4-digit ID Numbers.
• The ID Number is followed by the 3-digit ORANGE
  guide number to refer to, as well as the product
  name.
• Please note that some substances are highlighted
  in YELLOW and should be treated specifically.

• The BLUE Section
• In this section, the substances are listed in
  alphabetical order of their shipping names.
• The name of the substance is followed by the
  3-digit ORANGE guide number to refer to, as well
  as the ID Number.
• Please note that some substances are highlighted
  in BLUE and thus will have to be treated
  specifically.

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
ERG2004

• 6) The ORANGE Section (Guides)
• This section contains all the guides needed for
  the initial response phase of an incident
  involving dangerous goods.

18
ERG2004

• 6) The ORANGE Section (Guides) contains

The section Health or Fire or Explosion will
appear first depending on the primary hazards of
the type of substance.

6) The ORANGE Section (Guides) contains

• 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).

21
ERG2004

• 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.

22
ERG2004
In the YELLOW or BLUE Sections, if the substance
is 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.

23
ERG2004
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 indicate the specific distances
  to be used for each product

24
ERG2004

• 36 ORANGE Guides refer only to non-highlighted
  substances (non-TIH)
• 21 ORANGE Guides refer to both highlighted and
  non-highlighted substances (TIH and non-TIH)
• 5 ORANGE Guides refer only to highlighted
  substances (TIH).

It is then very important to verify if the
substance found in the YELLOW or BLUE-bordered
pages is highlighted or not, in order to use the
relevant distances from the ORANGE and/or GREEN
Sections, according to the indications provided
in the ORANGE Section.
25
ERG2004

• 7) The GREEN Section contains
• The TABLE OF INITIAL ISOLATION AND PROTECTIVE
  ACTION DISTANCES suggests the distances useful to
  protect people from vapours resulting from spills
  involving dangerous goods, which are considered
• Toxic by inhalation (TIH)
• Chemical Warfare Agents and
• Substances which produce toxic gases upon contact
  with water
• In this table, the substances are presented in
  numerical order of their ID Numbers.

27
ERG2004

• 7) The GREEN Section also contains
• The TABLE OF WATER-REACTIVE MATERIALS WHICH
  PRODUCE TOXIC GASES provides for each of the
  materials listed, the toxic gas(es) produced when
  in contact with water.
• In this table, the substances are presented in
  numerical order of their ID Numbers.

ERG2004

• The TABLE OF INITIAL ISOLATION AND PROTECTIVE
  ACTION DISTANCES provides, for small and large
  spills
• The Initial Isolation Zone.
• The suggested Protective Action Zone, downwind,
  for day and night.
• 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.

30
ERG2004

• Initial Isolation Zone

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

31
ERG2004

• 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
ERG2004

• Protective Action Zone

33
ERG2004

• Protective Action Zone Day and Night

• It is important to note that Protective Action
  Zones do not only depend on the mere presence of
  gases/vapours but mainly on its concentration in
  the air
• During the day, there is an increase of the
  atmospheric disturbances creating a greater
  dispersion (dilution) of the gases/vapours, which
  results in a weaker toxic concentration in the
  air and thus requires a smaller Protective Action
  Zone than at night.
• During the night, the gases/vapours will calmly
  dissipate. This will result in a higher toxic
  concentration in the air and consequently,
  necessitate a greater Protective Action Zone.

34
ERG2004

• Small and large spills

• Small Spill Generally involves a single small
  package (e.g., a drum containing up to
  approximately 200 litres), a small cylinder or a
  small leak from a large package.
• Large Spill Generally, a spill which involves
  a large package (more than 200 litres) or
  multiple spills from many small packages.
• For any intermediate quantity, the distances
  would need to be estimated between the distances
  provided for small and large spills.

35

• 2) Look up the materials 3-digit Guide number in
  either
• The ID Number index (YELLOW-bordered pages)
• The name of material index (BLUE-bordered pages)
• Note if the substance is highlighted
• As a last resort, if the ID number or the name of
  material are not available, use the Table of
  Placards and/or the Rail Car Road Trailer
  Identification Charts.

How to use the ERG2004

• 3) Turn to the numbered guide (ORANGE-bordered
  pages)
• Read carefully all the information provided in
  the ORANGE Guide and use jointly the GREEN
  Section if the substance is highlighted.

41
How to use the ERG2004

• CAUTION If a reference to a guide cannot be
  found and the incident is believed to involve
  dangerous goods
• Turn to GUIDE 111
• and use it until additional information becomes
  available.

• If the incident involves explosives

• Use GUIDE 112 for all explosives, except
• For Class 1.4 Explosives, use GUIDE 114.
