Using the following data, determine the probit constants and the LC50: Question 2: Chapter 2 question \# 2-34 The Immediately Dangerous to Life and Health (IDLH) concentration is defined as the concentration "that poses a threat of exposure to airborne contaminants when that exposure is likely to cause death or immedicte or delayed adverse health effects or prevent escape from such an environment." The IDLH implies a 30 min maximum exposure time. 3. The IDLH for chlorine gas is 10ppm. Use the probit equation for chlorine deaths to estimate the fraction of fatalities due to exposure at the IDLH for 30 min. b. Estimate the maximum exposure or evacuation time to result in no more than 1% fatalities at the IDLH level
