English term

emergency action level

English Science Nuclear Eng/Sci
emergency action level (EAL): A specific, predetermined, observable criterion used to detect, recognize and determine the emergency class of an event. An EAL could represent an instrument reading, the status of a piece of equipment or any observable event, such as a fire.


I have provided a definition for "emergency action level" as you can see. Yes, this definition is quite simple and I can understand it. What I cannot understand is the relationship between the three words of "emergency action level".

Does it mean the extent to which an action is urgent/vital/important/necessary? Or it means the level at which you should take an emergency action?

Do you think there are any other options?
Responses
5 +3 the level of INPUT signal at/above which emergency action is required
5 +1 the level at which emergency action must be taken

What I am trying to say is that definitions provided by other colleagues best describe "action level" not "emergency action level"
Masoud Kakouli Varnousfaderani (asker) Sep 5, 2016:
Action level vs emergency action level action level: The level of dose rate or activity concentration above which remedial actions or protective actions should be carried out in chronic exposure or emergency exposure situations.
emergency action level (EAL): A specific, predetermined, observable criterion used to detect, recognize and determine the emergency class of an event. An EAL could represent an instrument reading, the status of a piece of equipment or any observable event, such as a fire. In this sense, it is not strictly an action level as defined above, but has essentially the same function.
Masoud Kakouli Varnousfaderani (asker) Sep 5, 2016:
I think, based on the definition that I provided, there are no words which show actions should be taken
Masoud Kakouli Varnousfaderani (asker) Sep 5, 2016:
Daryo and others Let's supoose that"emergency action level" is only one value, a limit that if exceeded means "urgent action needed, but there is another term in IAEA terminology and its "action level" (without the word "emergency") and it means: the level of dose rate or activity concentration above which remedial actions or protective actions should be carried out in chronic exposure or emergency exposure situations. So, if what you believe is true, there are no differences between these two separate terms!

Furthermore, I think the definition that I provided clearly states that it is a criterion used to calssifiy accident: determine the emergency class of an event.
Daryo Sep 5, 2016:
NO "emergency action level" ... is simply a criterion used to classify the level of accidents. ...?

NO it's NOT and it CAN'T BE - if you want to use a variable (the value/intensity of an input signal) as a criterion for classification of accidents, you will need several value limits to define several levels/classes of accidents while "emergency action level" is only one value, a limit that if exceeded means "urgent action needed"
Masoud Kakouli Varnousfaderani (asker) Sep 5, 2016:
Any ideas about my posts in Discussion section?
Masoud Kakouli Varnousfaderani (asker) Sep 5, 2016:
I think definitions provided below are more or less describing "action levels", not "emergency action levels". Agree?
Masoud Kakouli Varnousfaderani (asker) Sep 5, 2016:
Now that I'm thinking I believe that "emergency action level" does not refer to taking action based on level of criticality. It is simply a criterion used to classify the level of accidents.
There are two terms based on IAEA terminologies, one is "emergency action level" and the other is "action level". If "emergency action level" means taking actions based on criticiality of accidents. So, what is "action level"? Based on IAEA, action level means: The level of dose rate or activity concentration above which remedial actions or protective actions should be carried out in chronic exposure or emergency exposure situations.
Masoud Kakouli Varnousfaderani (asker) Sep 5, 2016:
These criteria were not used as emergency action levels (EALs)6 which would trigger implementation of predetermined public protective actions without additional assessment and judgement off-site.

At the preparedness stage, there is a need to develop an emergency classification system based on observable conditions and measurable criteria (emergency action levels).

the level at which emergency action must be taken

that's the meaning

"must" rather than "should" be taken

sorry: should read "emergency"

neutral Daryo : you managed to make it as ambiguous as the original version! it could refer to the intensity of the fire as much as to the intensity of the firefighting efforts!

the level of INPUT signal at/above which emergency action is required

the "level" is the level of the INPUT signal, NOT the level/intensity of the response to the emergency situation

clue:
"... used to detect, recognize and determine the emergency class of an event"
=>
it's about the input of information, not the response

"input signal" in the most general way, as understood in cybernetics i.e. any information in any shape or form that is entering the system, be it a reading of temperature / luminosity / vibrations / radiation / magnetic field / humidity / sound level etc etc that is of such intensity that something is seriously wrong and immediate action is required
Note from asker:
If by signal you mean such as when you use your TV remote control to send a signal to your TV, I don't agree with you that much. I think it is the level/intensity of accident at/above which emergency action is required. Thanks for sharing your idea in advance. I added two sentences containing this word to see if this help.
