Your comment makes me think of this guy:
https://en.wikipedia.org/wiki/Rick_Rescorla#Corporate_securi...TL;DR: he got hired as a security officer for Morgan Stanley's WTC offices, and he made the employees regularly practice evacuations.
> Rescorla wanted the company out of the building because he continued to feel, as did Hill, that the World Trade Center was still a target for terrorists and that the next attack could involve a plane crashing into one of the towers.[17] He recommended to his superiors at Morgan Stanley that the company leave Manhattan office space, mentioning that labor costs were lower in New Jersey and that the firm's employees and equipment would be safer in a proposed four-story building. However, this recommendation was not followed because the company's lease at the World Trade Center would not terminate until 2006. At Rescorla's insistence, all employees (including senior executives) then practiced emergency evacuations every three months.[18]
> After Dean Witter merged with Morgan Stanley in 1997, the company eventually occupied 22 floors in the South Tower and several floors in a building nearby. Rescorla's office was on the South Tower’s 44th floor.[4] Feeling that the authorities lost legitimacy after they failed to respond to his 1990 warnings, he concluded that employees of Morgan Stanley, which was the largest tenant in the World Trade Center, could not rely on first responders in an emergency and needed to empower themselves through surprise fire drills, in which he trained employees to meet in the hallway between stairwells and go down the stairs two by two to the 44th floor.[15] Rescorla's strict approach to these drills put him into conflict with some high-powered executives, who resented the interruption to their daily activities, but he nonetheless insisted that these rehearsals were necessary to train the employees in the event of an emergency. He timed employees with a stopwatch when they moved too slowly and lectured them on fire emergency basics.[15][18]
