A good article is found on the above title, narrating lessons from five less known accidents. The lessons are,
- containment of water from fire fighting operations to avoid contamination of water sources in the rundown
- to consider all auxiliary equipment also as important as main plant equipment for understanding hazards
- not to ignore hazards and need for monitoring even during shutdown
- positive isolation, purging and checking for hazardous atmospheres (using flame is not a correct check for presence of flammable atmosphere)
- follow written approval system to override interlocks
- follow safety permit procedures
- identify the correct equipment before taking up work
- communicate with clear identification while handing over the equipment for maintenance
- ensure physical check by another agency before permitting equipment operation/maintenance
- hazards from dust, propagation of dust explosions
- preparation of emergency response management, with detailed instructions for every type of emergency
- good house keeping
- establish process safety management procedures
- inculcate good safety culture, starting from the top management
