Реальные аварии и роль process control
Цель: Изучить тему «Реальные аварии и роль process control» и закрепить её практическими заданиями и самопроверкой.
2 акад. часа чтение и разбор теории, решение задач, работа со схемой или виртуальным стендом и проверка понимания.
Основной материал
Uploaded Chemical Process Dynamics and Controls discusses Bhopal, Three Mile Island and Texas City to show how instrumentation, procedures and safety systems interact. The lesson is not «один датчик спас бы все», а системный: design, maintenance, alarms, operator training and safety culture matter together.
Texas City style lesson
Ignored/disabled high-level protection, startup procedure problems and relief/blowdown design combined into catastrophic event. Multiple weaknesses aligned.
Normalization of deviance
When nuisance alarm constantly ignored or bypass remains for months, abnormal state becomes accepted. This is organizational hazard as much as technical.
Практическая работа
Choose one incident from source and create barrier analysis: initiating event, failed controls, failed alarms/protections, organizational factors, lessons for instrumentation.
Самопроверка
• Why accidents rarely single-cause?
• How maintenance affects safety?
• What is normalization of deviance?
• Why nuisance alarms dangerous?
• Why procedures and automation must match?
