A semi-quantitative methodology for risk assessment of university chemical laboratory

Investigative Analysis of Safety Risk Assessment at a Science and Technology University: Analysis of 2019 Risk Assessment and 2021 Actual Accidents

“…A semiquantitative methodology comprising matter−element extension theory (MEET) implemented with a combination ordered weighted averaging (C-OWA) operator has been proposed to assess risks in a university chemical laboratory. 8 The applicability of the proposed method has been tested using real cases, and it has been shown to be a useful tool for risk assessment and management in university chemistry laboratories. Jang et al attempted to adopt a financial approach in risk assessment.…”

Inherent Hazards Assessment and Classification Method for University Chemical Laboratories in China

“…The industry is fraught with many types of hazardous chemicals, complex and changeable chemical reaction processes, and dangerous facilities. The chemical laboratory is a hazardous workplace laden with many flammable, explosive, highly toxic, high-temperature, and high-pressure substances. − University chemical laboratories are more dangerous than industry laboratories due to their lower safety investment, looser safety management and neglectful safety atmosphere. − In recent years, chemical laboratory accidents have occurred frequently in Chinese universities . Examples include: an explosion occurred in the laboratory of Beijing Jiaotong University on December 26, 2018, resulting in the death of three graduate students; a reactor explosion occurred in the laboratory of the Institute of Chemistry, Chinese Academy of Sciences on March 31, 2021, resulting in the death of a graduate student; a deflagration accident occurred in the laboratory of Nanjing University of Aeronautics and Astronautics on October 24, 2021, resulting in two deaths and nine injuries .…”

“…Pluess et al further compared LARA with Hazard and Operability studies (HAZOP), Failure Mode, Effects, and Criticality Analysis (FMECA), and Preliminary Hazard Analysis (PreHA), confirming that LARA can effectively identify hazards and assess risks, and is easier to implement because it does not require experienced analysts . Li et al proposed a semiquantitative risk assessment method using Combination Ordered Weighted Averaging (C-OWA) operator and Matter-Element Extension Theory (MEET) to evaluate the integrated risk of university chemical laboratories mainly from human, equipment, material, environmental, and management factors . However, existing research lacks an effective quantitative evaluation method for the inherent hazards of university chemical laboratories, and the research on risk classification management strategies for university chemical laboratories is insufficient.…”

Quantitative risk assessment of college campus considering risk interactions

“…Rahman created a framework to quantify the safety of high-rise structures on the campus, and the outcome revealed that buildings housing the chemical department are at risk [ 6 ]. Li et al presented a semi-quantitative approach using the Combined Ordinal Weighted Average ( C -OWA) operator and the Matter-Element Extension Theory (MEET) to assess and evaluate the risk in chemical labs of universities [ 7 ]. Chi-square and correlation tests were used to prove that the infrastructure and operations of labs, libraries, and power plants within college campuses may be vulnerable and prone to major accidents [ 8 ].…”
