Hazard quotient is the level of exposure divided by the provisional RfD then rounded to one or two significant
decimal places or digits. See Worksheet E01 for summary of exposure assessments. Hazard quotients >0.5 and
<1.5 are shown to two significant digits. All others are rounded to one significant decimal place or integer.
