On an industrial estate the governing fire is the one next door
A tank fire at a small chemical plant in Ulsan on 14 October hurt nobody and evacuated about 7,000 people, almost all of them from the construction site across the boundary. Fire safety design bases stop at the fence.
On a turnaround the thing that kills the contractor is not a fire
Two contractors died during preventive maintenance at a refinery last week, with no fire involved. The maintenance window's lethal hazard is isolation — and contracts buy it as a procedure, not as engineering.
On a hydroprocessing unit the detection layer is specified for the wrong gas
A fatal separator rupture last week released hydrogen-rich gas. Infrared point gas detectors cannot see hydrogen at all, and flame detectors that confirm on a hydrocarbon signature barely see the fire.
On an NGL train the governing fire is a jet fire, not a pool fire
Construction started this week on a fifth NGL fractionation train in the UAE. On gas processing plant the credible fire is a pressurised jet, and fire protection qualified on a pool-fire curve does not cover it.
Ammonia is a toxic release problem wearing a fire scope
Three ammonia announcements in ten days show where Gulf capacity is going. Ammonia is flammable on paper and toxic in practice, and a fire scope written for hydrocarbons protects the wrong consequence.
Fire protection during a shutdown is a contract gap, not a site discipline problem
In the past ten days the industrial fires that killed people were on plant that was not running. The non-operating state is the high-consequence state, and it is the one most contracts leave unowned.
Changing foam concentrate is a system change, not a procurement decision
The regulatory clock on fluorinated foam has started, and the instinct is to treat the changeover as a purchase order. It is not. Swapping the concentrate invalidates the basis on which the whole foam system was approved.
Fire water demand on a process plant: which scenario actually governs
The largest single demand is rarely the design case. What decides the size of the whole system is the combination you are required to assume happens at once.
