Guide 111
Use when the dangerous placard is displayed or the material is unknown
Use the table of markings labels and placards when…….
Materials can’t be identified by the shipping papers, numbered placard or orange panel number page 8-9
GHS stands for?
Globally harmonized system of classification
Yellow pages are for?
If you have the 4 digit ID number
Blue Pages are for?
If you have the name of the material
If the material in the yellow and blue pages is highlighted green?
Without fire
With fire
If there is no fire
Go to table 1 of green pages
Identify initial isolation distances
Then consult orange guide
With fire
Orange guide for evac distances
Then green table 1 downwind distances
For explosives divisions 1.1,1.2,1.3,1.5 use guide….

For explosives divisions 1.4, and 1.6 use guide……

Orange page guides contain what info?
P
P
E
-Potential Hazards-
Fire or Explosion
Health
-Public Safety-
Protective clothing
Evacuation
-Emergency response-
Fire
Spill or leak
First aid
Green Pages provide what info?
Initial Isolation and protective action distances.
Small spills and large spills
Isolation distances day or night?
Used to protect people from vapors resulting from spills that are considered toxic by inhalation (TIH or PIH)
Using the green pages the + symbol means ?
Distance can be larger in certain atmospheric conditions
Table 2 of Green Pages contains
Water reactive materials which produce toxic gases. List materials that produce large amounts of TIH when spilled in water.
Initial isolation zone
Area surrounding the incident in which persons may be exposed to dangerous and life threatening concentrations
Protective Action zones
downwind from the incident
could become incapacitated
unable to take protective action.
incur serious or irreversible health effects.
NRC is what?
National Response Center
Ran by Coast guard
Need to be notified of spill
Table 3 of the green pages
List initial isolation and protective action distances for TIH materials more commonly encountered I.e. large spills Ammonia Chlorine Ethylene oxide Hydrogen chloride Sulphur dioxide
Protective actions decision factors to consider
-The dangerous goods- Degree of health hazard Chemical and physical properties Amount involved Containment of release Rate of vapor movement
-the population threatened-
Location
Number of people
Time available to evac or shelter in place
Ability to control evac or shelter
Building types
Special institutions i.e. Nursing homes, prisons
-weather conditions-
Effect on vapor and cloud movement
Potential for change
Small spill considered
55 gallons or less
Large spill size
Greater than 55 gallons
Two types of class b foams
Regular AFFF protein based mostly for petroleum based products
ARFF Alcohol resistant foam
AEGL
Acute exposure guideline level
What guide for red class placard? Has flame with line under it
Guide 127
What guide for a corrosive class 8 placard. Half white half black with liquid pouring on metal and hands
Guide 153
ERG is used when
Initial phase of a transportation incident
Double digit? on the top of a un label ghs label
Intensification of that hazard
PIH
TIH
Poisonous inhalation hazard
Toxic inhalation hazard
In green pages + means?
Distance can be larger in certain atmospheric conditions
If guide has a p next to it?
Material may suffer from violent polymerization
Corrosive placard what guide ?
153
Flammable class 3 what guide ?
127
Un number starting with X
I.e. X88 means what
Will react dangerously with water
Un number with a zero?
Follows a single digit i.e 30 is flammable liquids
