After calculate the density per hour of average maximum surface of the earth from the distance below-wind of chlorine gas, we did modeling experiment harmful danger distance(LOC) from the distance below-wind of chlorine gas about the density; TLV-TWA(Threshold Limit Values-Time Weighted Average), IDLH(Immediately Dangerous to Life or Health)-American legal restriction density used for evaluation of harmful possibility of danger, total release time(Strength), the release quantity per minute and an inhalation dosage(Dose) on depending change of the wind speed and the temperature. According to the result of modeling experiment, harmful danger distance was the following outcome, in case of the wind speed 2m/sec, it was 6.4Km;in case of the wind speed 10m/sec. it was 9Km, so the harmful danger distance responded to the change of the wind speed sensitively. And as a determinate cause of release time of harmful poisonous material is the temperature, in case of 20℃, the release time was 2’10”; in case and 35℃, it was 2’, so the release time increased when the circumference temperature was low. Moment inhalation dosage was, in case of wind speed 2m/sec, more than 1,000,000ppm and in case of 10m/sec, it was about 2,000ppm. Besides we give a result that in case of the circumference temperature 20℃, it was about 200,000ppm but in case of 3 5℃, it was 600,000ppm. So
