3 Awareness Level Actions At Hazmat Incidents Flashcards
Isolation and protective distances in the erg are based on
Open areas associated with transportation avenues, not fixed facilities or urban settings
When the four digit UN code is located where would it be found in the erg
Yellow section
When a chemical name is known it can be found where in the erg
Blue section, spelling is key, may be off by a few letters
By locating the placard how can it be looked up in erg
Find three digit code associated with placard in the table of placards in front of the book
The shape and profile of a container can be referenced where in erg
White pages, front of book. Then reference guide number to the Orange section of the book
What enables responders to locate the most specific initial action guide in erg
Four digit code or chemical name
The purpose of the yellow section of erg
Quickly Id material to reference orange guide section
If the material is highlighted in the yellow or blue section it means
Toxic inhalation hazard
Blue pages of erg provide
Alphabetical chemical names with corresponding four digit codes
Most important part of erg
Orange section, initial action guides
Left and right side of orange initial action guide to erg
Left side, safety related info
Right side, emergency response guidance, first aid, spill or leak action, firefighting action
Each guide portion in the Orange, initial action guide, is designed to cover similar materials and contains three sections:
Potential hazards, public safety and emergency response
No the otentia, hazards section, where is the highest hazard listed
First
What does the public safety action of Orange action guides provide
General info of isolation and PPE, Evac distances, fire situations
Common first aid recommendations of erg
Call ems, assistance, move victims to fresh air, flush contaminated skin and eyes with running water
Awareness level should not enter
Hazardous atmospheres or contaminated areas
Awareness level cannot handle or touch
Potentially contaminated victims, even for basic first aid
Green pages, table of initial isolation and protective action distance provides two different recommended safe distances
Initial isolation
Protective action distance
Protective action distance
Downwind distance from hazmat where protective actions should be implemented.
Small, and large spills defined by erg
Less than 53 gallon small, up to 55 gal drum
More than 53 gal is large
What are Evac distances divided into night and day
Atmospheric conditions differ and will be more dispersed during warmer day than cooler night.
Single most important factor for Evac distances
Concentration of contaminant in air
Initial isolation distance
Initial distance of evac in all directions always at least 100’
Initial isolation zone
Circular zone, radius equal to initial isolation distance, where people may be exposed dangerously upwind, and life threatening down wind.
If hazmat is burning or leaking longer than 30 min
Green section isolation zones and distances don’t apply, and Orange must be referenced
Usa popular emergency response center
Chemical transport emergency center CHEMTREC, non government.
When in contact with an emergency response center the person should collect and provide what info
Caller name, call back# and fax Location and nature of problem Name and ID of material Point of origin Carrier name or reporting marks Container type and size Local conditions and resources Injuries and current conditions Emergency services already notified
Emergency response centers will provide
Confirm chemical emergency or not Record details Tech assistance Contact shipper of material and experts Provide shipper with callers contact info to deal with them
Most important way of awareness and ops to ensure safety of themselves and others
Isolation and scene control
Isolation and scene control involves
Physically securing by establishing perimeters, denying entry, preventing contaminated people and items from leaving, Evac, defend in place
Isolation perimeter
Outer cordon, outer perimeter
Outer boundary controlled to prevent entrance of public or unauthorized people
Isolation perimeter can be expanded and reduced as needed
True false
True
If involved in terrorist incident personnel should
Document observations,
Take pictures
Make note of witness observations
Protect evidence
Erg is primarily designed for use where
Road and rail
