Over time, the dark checks become light, and the light checks become dark (typically at a rate of 4 reversals per second). Certain conditions including complete congenital stationary night blindness, melanoma-associated retinopathy, and juvenile X-linked retinoschisis produce a characteristic abnormality of this response that has been termed electronegative. Specifically, the a-wave has a normal (or nearly normal) amplitude, whereas the b-wave is markedly attenuated. It includes health and fire or explosion potential hazard information (with the more dangerous hazard listed first). BLUE Materials ordered by dangerous goods material name. The pERG waveform consists of a small negative deflection near 35 ms, termed the N35 component, a positive deflection near 50 ms, termed the P50 component, and a negative deflection near 95 ms, termed the N95 component. As an emergency responder, its crucial to understand how to use the emergency response guidebook (ERG) before an incident ever happens.
