Upwind, uphill, or upstream At a safe distance Read placard or orange panel |
|
|
If entries are highlighted in green, and THERE IS NO FIRE, what steps should be followed within ERG? |

IF THERE IS A FIRE or A FIRE IS INVOLVED = Also consult orange guide |
|
|
What does an entry with "When Spilled in Water" within green section of ERG mean? |
Materials produce large amounts of Toxic Inhalation Hazard (TIH) gases when spilled in water |
|
|
What area SURROUNDING the incident in which persons may be exposed to dangerous (upwind) and life threatening (downwind) concentrations of material? |
Initial Isolation Zone = SURROUNDING |
|
|
What 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? |
Protective Action Zone = DOWNWIND |
|
|
What if more than one tank car containing TIH materials involved in the incident is leaking? |
LARGE spill distances may need to be increased |
|
|
Which Protective Action Distance should be chosen if it is not clear whether the spill is on land or in water, or in cases where the spill occurs both on land and water? |
Choose larger Protective Action Distance |
|
|
What means are to keep everybody away from the area if they are not directly involved in emergency response operations? |
Isolate Hazard Area and Deny Entry |
|
|
What means to move all people from a threatened area to a safer place? |
Evacuate |
|
|
What means people should seek shelter inside a building and remain inside until danger passes? |
Shelter In Place |
|
|
What is used when evacuating the public would cause greater risk than staying where they are, or when an evacuation cannot be performed? |
Shelter In Place |
|
|
What should you direct for Shelter In Place? |

|
|
What is considered NIGHT time? |
Between sunset and sunrise |
|
|
What symbol or shape is the Protective Action Zone considered for practical purposes? |
Square - length and width are the same as the downwind distance |
|
|
What symbol or shape is shown where the spill is located? |
