Map interacting jobs in a risk review
Assess interactions as well as individual task hazards. Review overlapping work and coordinate timing, areas and equipment use.
Safe work
What changes during a shutdown?
HSE chemical-plant permit guidance considers isolation, draining, flushing, risk assessment and communication together.
Before opening a process line
HSE maintenance guidance addresses isolation and stored energy. Confirm equipment identity before breaking containment.
Handing over isolation information
HSE highlights preparation, information exchange and cross-checking by the incoming shift. ‘Under maintenance’ is insufficient isolation detail.
Communicating a stop-work concern
Korean OSH Act article 52 addresses imminent-danger withdrawal, prompt reporting and action, with conditions for protection against adverse treatment. It is Korean law.
Residual pressure after draining
HSE isolation guidance addresses draining, isolation and changing process conditions. Operating a drain is not proof that residual hazards are gone.
