While I agree that preservation of life is a high priority, one must
evaluate the business reality of what you're saying.
Take a 50-story office building (or in Dallas's case, a couple dozen of
them), in which you want a battery plant. The first floor is off limits
(public access, lobby use, etc) as well as the fourth to the fiftieth. That
means you have two floors of battery to power the other forty-seven? Not to
mention the safety issues in hauling that amount of DC power up to the
fiftieth floor. Throw in the proposed bans on diesel backup generators and
you might as well forget batteries altogether.
Or do you propose all existing carrier hotels (typically high-rises) be
dismantled and replaced with large numbers of three-floor buildings? While
short buildings may be a necessity in earthquake-prone areas like
California, they're simply not economically viable in the rest of the
I understand there are safety implications for the public, facility staff,
and emergency services. I would support a proposal for mandatory markings,
access control, environmental containment, fume ventilation, or any other
reasonable safety measures; I can't support any proposal that effectively

This is disturbing, I think that people, environment and property are
the crux of importance in the order stated.
Above the 3rd floor is a risk to human life and therefore
unacceptable, being A First Responder Operational (FRO)
I can clearly see this as a serious risk, technical details of
burning acid fumes omitted.
