It includes health, life, vigor, war, courage, anger, and love. fERG is useful for assessing macular function in conditions such as age-related macular degeneration, however good fixation from the subject is required. The imwaveplicit time of the a-wave is measured from the time of the flash to the trough of the a-wave. YELLOW - Materials ordered by 4-Digit UN/NA Number. This section of the ERG describes the distances necessary for initial isolation around a chemical incident as well as the distance downwind that persons must be protected. The yellow-bordered pages index the list of dangerous goods in numerical order of 4-digit ID numbers. When looking for a chemical name, remember that just a few letter off can be the difference between an acid, base, or even an oxidizer. (2003).
