How do you find an ERG? Doc Oph. A value of 0 means that the material poses essentially no hazard, whereas a rating of 4 indicatesextreme danger. Contact information for need to know agencies have been updated. The ERG is divided into sections, each with its own color. An electroretinography (ERG) test, also known as an electroretinogram, measures the electrical response of the light-sensitive cells in your eyes. Reference and ground electrodes are commonly made of a highly conductive material that is fixed to the patient with paste. The ERG helps first responders quickly identify the hazard(s) of the materials and protect themselves and the general public during the initial response phase of an incident. Curr Diab Rep. 14:526. Using this model he was able to demonstrate the physiology underlying different ERG sources by altering the level of anesthesia and observing the loss of different ERG components. Well, dig it out and lets take a look at the coffee stained headache. For non-transportation related hazardous materials incidents, emergency responders should seek additional information to assist with interpretation of chemical properties and spill dynamics. His background ranges in experience from urban to rural response and from Type 3 to Type 1 teams. 6 Which is the most dangerous Toxic Inhalation Hazard?
