The paint formerly used on some storage tanks contained aluminum powder, which reflected heat from the surface of the tanks. Why did experts recommend grounding these tanks and storing only noncombustible material in them? Why is the installation of an automatic sprinkling system recommended in machine shops that use lathes to fabricate titanium parts? Be specific.
