储运联合车间乙烯罐区的风险评价与安全管理

RISK EVALUATION AND SAFETY MANAGEMENT IN THE ETHYLENE TANK FARM OF JOINT STORAGE AND TRANSPORTATION WORKSHOP

乙烯是一种无色微甜味的气体,易燃。与空气混合能形成爆炸性混合物,遇明火、高热能引起燃烧爆炸。与氟、氯等能发生剧烈的化学反应,具有较强的麻醉作用。吸入高浓度乙烯可立即引起意识丧失,无明显的兴奋期,对眼及呼吸道粘膜有轻微刺激性,液态乙烯可致皮肤冻伤。长期接触,可引起头昏、全身不适、乏力、思维不集中。因为乙烯是重要且危险的化工原料,所以必须加强对乙烯罐区的安全管理。

Ethylene is a colorless and slightly sweet gas that is flammable. If it mixes with air, explosive mixture can be formed, which will cause combustion explosion in the event of open fire and high heat energy. Violent chemical reactions may occur when it contacts with fluorine and chlorine, which has strong anesthetic effect. Inhalation of high-concentration ethylene can cause immediate loss of consciousness, no obvious excitement, and slight irritation to the eyes and respiratory mucosa. Liquid ethylene can cause skin frostbite. Long-term contact with ethylene can cause dizziness, general discomfort, fatigue, and no concentration of thinking. Because ethylene is an important and dangerous chemical material, it is necessary to strengthen the safety management of the ethylene tank farm.
