Color Hazard Orange Explosive Red Flammable or combustible Green Non-flammable gas Yellow Reactive oxidizer or organic peroxide White Toxic/Poisonous or infectious substance The resulting mfERG waveforms (shown below) are similar in shape to those of the light-adapted ffERG: there is an initial negative deflection (termed N1), followed by a positive deflection (termed P1), and a second negative deflection (termed N2). An example of a common pERG stimulus is shown below (See Figure 3, left). The trace below (See Figure 3, right) shows the pERG from a visually-normal individual (average of 150 responses). Rapid flicker is a useful stimulus for assessing cone-pathway function, because rod photoreceptors generally cannot follow rapid flicker. Yellow: This section is key in determining what exactly is involved in your incident. In 1908, Einthoven and Jolly separated the ERG response into three components: a-wave, b-wave, and c-wave, which are further described below. White, Yellow, Blue, Orange, Green, White What information is in the First white pages of the ERG? Example mfERG responses from a normal eye are shown below. The amplitude and implicit times of the a- and b-waves are quantified in the same manner as that for the dark-adapted responses shown in panel B. They form part of the back of the eye known as the retina. The marking must be on two opposing sides of a bulk packaging. (2015).

A minimum set of responses that should be obtained has been defined by the International Society for Clinical Electrophysiology of Vision (ISCEV) in 1989, which were most recently updated in 2015. mfERG responses are recorded under light-adapted conditions from the cone-pathway. The source of the P50 is debated, but there is some evidence suggesting that it is generated by RGCs with additional contributions from more distal sites. Another type is a fine thread placed on the cornea. The system uses a color-coded diamond with four quadrants in which numbers are used in the upper three quadrants to signal the degree of health hazard (blue), flammability hazard (red), and reactivity hazard (yellow).
