Key Terms to Review (22)
American Institute of Chemical Engineers (AIChE): The American Institute of Chemical Engineers (AIChE) is a professional organization that represents chemical engineers and promotes their interests. AIChE provides resources, networking opportunities, and a platform for discussing important issues related to chemical engineering, including ethics and safety. It also plays a vital role in establishing professional standards and best practices that guide chemical engineers in their work.
Conflict of interest: A conflict of interest occurs when an individual's personal interests, whether financial, relational, or otherwise, potentially interfere with their professional responsibilities and decision-making. This situation can undermine trust and integrity in professional fields, especially in chemical engineering, where ethical decision-making is crucial for safety and public welfare.
Deontological ethics: Deontological ethics is a moral theory that emphasizes the importance of rules and duties in determining the morality of actions. This approach holds that some actions are intrinsically right or wrong, regardless of their consequences. In the context of ethics and safety in chemical engineering, this means prioritizing adherence to established guidelines and principles to ensure safety and integrity in engineering practices.
Environmental Impact Assessment: An Environmental Impact Assessment (EIA) is a systematic process used to evaluate the potential environmental effects of proposed projects or actions before they are carried out. This assessment helps identify any adverse impacts, allows for the consideration of alternative approaches, and ensures that measures are taken to mitigate negative consequences on the environment, thus promoting ethical and safe practices in engineering.
EPA Guidelines: EPA guidelines are a set of regulations and recommendations established by the Environmental Protection Agency aimed at protecting human health and the environment. These guidelines provide a framework for waste management, sustainability assessments, hazard identification, and ethical practices in chemical engineering, ensuring that industries operate within safe and environmentally sound parameters.
Failure Mode and Effects Analysis (FMEA): Failure Mode and Effects Analysis (FMEA) is a systematic method for evaluating processes to identify where and how they might fail and assessing the relative impact of different failures. This proactive approach helps engineers prioritize potential failure modes based on their severity, likelihood, and detectability, making it an essential tool for ensuring safety and reliability in engineering applications.
Fault Tree Analysis (FTA): Fault Tree Analysis (FTA) is a systematic, deductive method used to analyze the causes of system failures. It visually represents the various pathways that can lead to a specific undesired event, often called a top event, by mapping out the combinations of faults or failures that contribute to it. This technique is essential for enhancing safety and reliability, particularly in fields like chemical engineering where understanding risks and ensuring safety is crucial.
Hazard Analysis: Hazard analysis is a systematic approach used to identify, evaluate, and prioritize potential hazards associated with a process, equipment, or operation. This process is crucial for ensuring safety and preventing accidents by proactively addressing risks before they lead to harm. By understanding the potential hazards, engineers can design safer systems and implement effective risk management strategies.
Hazard and operability studies (hazop): Hazard and operability studies (HAZOP) are systematic assessments used to identify potential hazards and operational issues in chemical processes. This method focuses on evaluating how deviations from normal operating conditions can lead to safety risks and inefficiencies, ensuring that all aspects of a process are analyzed thoroughly. By identifying these issues early, HAZOP helps improve safety and reliability in chemical engineering practices.
