back section of the white pages
Where is the four digit UN/NA ID number located?
Yellow border
Green highlighting in the yellow boarded index indicates that the substances are what
Gases or may release gases that are toxic and inhalation hazards p. 104
TIH is also also known as
Poisonous inhalation , hazard PIH
The P following the guide numbers indicates material is
polymerizes
What is a violent reaction that releases great amounts of heat and energy
Polymerization
Other terms denoting possible polymerization include:
M
S
I
monomer , stabilizer and inhibitors
What boarded pages of the ERG provide an index of dangerous goods and alphabetical order by name?
Blue border
Green highlighting on substances listed in the blue boarded pages indicates what
Release of TIH p. 105
What is the books most useful section color?
Orange bordered sections
What color boarded section provide safety recommendations in general hazard information
Orange bordered section
The potential hazard section addresses how many hazard types under separate headings ‘’’ WHAT IS LISTED FIRST ?
2 hazards:
fire or explosive hazards.
The highest Hazard potential is listed first.
What section provides some initial precautionary actions for first arriving or on scene personnel also provides general information regarding protective clothing, and respiratory protection recommendations and evacuation distances for small and large spills and for fires
The public safety section in orange board pages p. 106
What is the distance within which all personnel should consider for evacuation in all direction from hazmat spills or leaks?
Initial isolation distance
Initial isolation distance can be used to identify and establish what
Initial isolation zone p. 107
What personel will be involved in evacuation beyond the initial isolation phase
Awareness level personnel
What section describes emergency response topics including precautionary for incident involving fire, spills at leaks and first aid
3rd section in the emergency response section
p. 108
Who should never enter hazardous atmospheres or potentially contaminated areas?
Awareness level personnel
Who should not handle or touch contaminated or potentially contaminated victims at hazardous incident, even to provide basic first aid
Awareness level person
The ‘’ section consist of three tables. What are they?
Table 1: initial isolation and protective action distance
Table 2: water reactive materials which produced toxic gases
Table 3: initial isolation and protective action distance for (six common TIH)
green boarded
Table one in the green boarded section lists TIH materials by
Four digit UN/NA ID number p. 110
What conditions can significantly affect the size of a chemical hazard area?
Atmospheric p. 111
The warmer more active atmosphere common during the day disperses chemical contaminants more WHAT than cooler, calmer conditions common at night
Readily
Lower toxic concentration may spread over a larger area during the’’ as compared to the ‘’ when higher concentrations may exist in a smaller area
day/ night
The initial isolation distance provided in the ‘’. Pages are the distances within which all person should be considered for evacuation in the direction from an actual hazardous material spill/leak source. This distance will always be at least.
green bordered/ 100 feet
If hazardous materials are on fire or have been leaking for longer than what the ERG table does not apply
30 mins
Table 2 List, water reactive materials with produce large amounts of PIH gases and materials spilt in water. It also identifies the TIH gases produced as a result of the spill the materials are listed in ‘’ order. If the water reactive material is ‘’ a TIH and this material is ‘’ spilled in water table 1 /2 do not apply in the safety distances will be found within the appropriate ‘’ guide.
id # , not , not , orange
Isolation distance is provided in the ‘’’ boarded pages
Orange
Six ‘’’ hazards materials
Ammonia, anhydrous
Chlorine
Ethylene oxide
Hydrogen chloride
Hydrogen fluoride
Sulfur dioxide
toxic inhalation
Table 3( green boarded pages) has a chart to assist in the estimation of what
Wind speed
Wind speed is broken down into three descriptions, which are
Low medium and high
Wind speed estimates are not only useful for hazardous isolation and protective distances but can also be used for other emergency services such as:
AA
FT
F
air Ambulance landings
Firefighter tactics
Use of products such as foam p. 112
What is on the first page of an ERG?
A flow chart, addressing each step in the decision-making process, especially useful for new users. 113

Isolation perimeter p. 114
At any hazmat incident ‘’’ personnel should do all the following:
Isolate Incident/ deny entry
Prevent contaminated person/animal from leaving the scene
Avoid contacting contaminants
Remember that WMD agents may be deadly and small amounts and biological agents may not cause symptoms for several days
awareness level
What pages at the back of the ERG provide the differences between chemical biological and radiological incidences and possible indicators?
White pages p. 115
Awareness level personnel, maybe become an important witness if so, law-enforcement will want to know what you saw so once you do the following:
DO
TP
NW
PE
Document your observation
Take pictures photos if possible
Make note of other witnesses
Protect evidence
Any photo or video maybe come what and phones maybe
Evidence/confiscated
’’’’’’ personnel should collect and provide as much information as possible, including:
Chemical involved known
placard/ label if, visible
Location of inciden
Size of incident
Direction in which the plume is moving
Altitude and movement of the plume
Color of the smoke
Significant changes and conditions

Description of a vehicle involved/any identification marks numbers or placards p. 117
Awareness level
The orange boarded pages organizes individual guides presented in two page format featuring three sections, the left page lists “”” the right page provides “””
