Reliability evaluation of a medical oxygen supply system by FTA based on intuitionistic fuzzy sets.

The main objective of healthcare centers is to ensure a consistent and high-purity oxygen supply for the safety of patients. Pressure Swing Adsorption (PSA) is a commonly used technique for supplying medical oxygen by eliminating nitrogen from the ambient air. Due to the increased fire risk associated with oxygen, any malfunctions in the oxygen supply system can lead to serious hospital fires.

Using fuzzy cognitive map in bow tie method for dynamic risk assessment of spherical storage tanks: A case study.

The present study aimed to perform a dynamic risk assessment of liquefied petroleum gas (LPG) in spherical storage tanks using the Hazard and Operability (HAZOP) method. The "LPG release from spherical storage tank" scenario was determined to be a top event based on the risk level. The causes and consequences of this scenario were then specified using the Bow-Tie method.

Dynamic risk assessment of hospital oxygen supply system by HAZOP and intuitionistic fuzzy.

Events such as oxygen leakage in the oxygen generation systems can have severe consequences, such as fire and explosion. In addition, the disruption in the oxygenation systems can lead to a threat to patients' lives. Thus, this study aimed to identify the significant deviations in the oxygen supply system as critical equipment at hospitals based on the Hazard and Operability (HAZOP) method.

Scoping Review of 5 Common Occupational Cancers and Their Related Exposures.

Occupational cancers can be avoided by removing dangerous chemicals from the workplace or limiting occupational exposure. Approximately, 10 major risk factors account for 85% of all occupational cancers. This scoping review study aimed to determine the most important chemical carcinogens related to 5 known occupational cancers.

Understanding factors influencing workers' unsafe behaviors through social network analysis in the mining industry.

. In this study, we aimed to discover why workers engage in unsafe behaviors and reach a deep understanding of all causes influencing unsafe acts among workers in a mining industry. We also aimed to determine which causes play a more important role in the occurrence of unsafe acts.
