Abstract
On April 21, 2021, four workers died because of gas poisoning while attempting to maintain an agitator in a reactor at Heilongjiang Kailunda Technology Co., Anda, Heilongjiang Province, China. The event was characterized as a major incident occurring within a confined space. This article analyzes the incident by comparing China's and the US's safety regulations and standards regarding entry into confined spaces. The article concludes with the lessons learned and puts forward suggestions for the prevention of such incidents and for safety improvements in China.
期刊介绍：
Process Safety Progress covers process safety for engineering professionals. It addresses such topics as incident investigations/case histories, hazardous chemicals management, hazardous leaks prevention, risk assessment, process hazards evaluation, industrial hygiene, fire and explosion analysis, preventive maintenance, vapor cloud dispersion, and regulatory compliance, training, education, and other areas in process safety and loss prevention, including emerging concerns like plant and/or process security. Papers from the annual Loss Prevention Symposium and other AIChE safety conferences are automatically considered for publication, but unsolicited papers, particularly those addressing process safety issues in emerging technologies and industries are encouraged and evaluated equally.
