Emergency exposure guidance levels

Chapter 5 Toxic Release and Dispersion Models Table 5-7 Emergency Exposure Guidance Levels (EEGLs) from the National Research Council (NRC) (all values are in ppm unless otherwise noted) ... 

It should be noted that, for establishment of a 1-h Emergency Exposure Guidance Level (EEGL) for another halocarbon, the NRC (NRC 1996 Bakshi et al. 1998) recommended application of a single interspecies UF of 10 to the cardiac sensitization test with the dog. Because blood concentrations of several halocarbons rapidly reached equilibrium, the NRC also extrapolated this 10-min test to the longer time period of 1 h. Controlled human data were not available for many of the materials considered by the NRC, whereas human data are available for HCFC-141b. 

National Academy of Sciences (NAS)/National Research Council (NRC) emergency exposure guidance levels (EEGLs) and short-term public emergency guidance levels (SPEGLs). 

Emergency exposure guidance levels (EEGLs for 15 min, 1 h, and 6 h) for emergency situations resulting in exposure of personnel for less than 24 h.
