Consequence Evaluation of Chlorine Release in Latex Glove Manufacturing by ALOHA and MARPLOT- การประเมินการรั่วไหลของสารคลอรีน ในโรงงานผลิตถุงมือยางแห่งหนึ่งในจังหวัดสงขลา ด้วยโปรแกรม ALOHA และ MARPLOT

Abstract

Chlorine is a toxic substance. Its leakage causes severe health effects and maybe lethal. Planning to control relevant safety measures is critically important. The purpose of this study was to evaluate the effect of chlorine leakage from storage tanks in chlorine dispensing process in a rubber glove factory in Songkhla province. Seasonal simulations were performed for 3 seasons by using ALOHA (Area Locations of Hazardous Atmospheres) and MARPLOT (Mapping Application for Planning and Local Operational Tasks). The results showed that in the summer, there was a maximum leakage at ERPG-3 (20 ppm concentration) at and escape distance of 852 meters, in winter at 825 meters and in the rainy season at 815 meters in the rainy season. There will be a spread of chlorine to the northeast. Winter and summer will spread to the southwest. Leakage distance at ERPG-2 (concentration 3 ppm). The rainy season has the highest spread at a distance of 2 kilometers to the northeast. Winter and summer are equal at 1.7 kilometers to the southwest. The leakage level at the ERPG-1 level (concentration 1 ppm) in the rainy season has the highest spread at a distance of 3.1 kilometers to the northeast. Winter and summer are equal at 2.6 kilometers to the southwest. Therefore, planning to support in the event of an emergency in each season must cover the spread at ERPG-1, 2 and 3 levels. Which can use the leakage distance to be used in the preparation of emergency plans with factories that are at risk of chemical leakage in the same area.
