I can fully understand this as I had worked in a R&D chem lab for a
battery manufacturer many, many years ago. Back then, we had the full
complement of lab safety equipment including a so called expolsion proof
room with spring loaded trap door in the ceiling and reinforced walls.
We always knew what the dangers were and how to protect ourselves from
them.
However, I think that many (most?) SLA installations are in mechanical
engineering oriented departments. They are not familiar with chemical
handling and their mindset is geared towards installation of machine
tools. Therefore, because of their culture and experiences, much of the
SLA hazards are overlooked.

WOW!!! I could never get that through my management.
