Planning for weather events is sometimes overlooked. Here is a recent story where all the planning and preparation worked when it needed to.
The
strike of lightning at dawn on Monday on the (company name omitted) alumina
plant, located in the municipality of (name omitted), forced the refinery to
stop production for a few hours. The situation was as circumstantial as it was
unusual, as even veteran workers could not recall a similar incident, although
it was quickly resolved.
The
event occurred around 5:30 a.m., when the systems that govern the activity
became unbalanced, and around 9:00 a.m. the alumina plant had returned to
normal, without causing damage to the machinery. The foundry area of the
aluminum factory was not affected by the lightning.
The
storm caused the shutdown of the three units of the steam department , which is
essential for production at the plant, since the entire production system to
obtain alumina from bauxite depends on this gas.
Bauxite is first crushed
in the digestion department, which relies on steam to increase its pressure and
complete the crushing. Once this process has been carried out, the raw material
is heated and diluted with caustic soda. Hence, the plant stopped, as one of
the first and essential steps in the production chain was disabled. In
addition, if the situation continued over time, the excess current produced by
the storm could have compromised the integrity of the equipment.
The
interruption caused surprise and some initial fright among the staff, although
the lightning rod system worked correctly and there was no damage to the
machines or any risk to the operators.
On our travels when we visit plants we will talk about extreme
weather events and how our host plans for them. We will bring this story up
when we talk about lightening.
We would be remiss if we did not state that we are so happy to write about an incident that resulted in no injuries.
