Security is PvP, safety is PvE. Different game, different tactics.
Humans are reckless idiots. If circumventing safety systems means they can go home 15 minutes earlier (or if it's the only/simplest easy to get reach some unrealistic high daily goal dictated from higher ups), some of us will happily risk their own health, and that of a whole city, to do so.
Still though, security is fighting against an opponent who searches for weak points and exploits them to the max. "Safety" protects against random natural accidental events (either internal or external in origin). If someone is just trying to get home, they want to get the job done quickly sure, but their intent is not to cause damage, their actions aren't targeted. It's a different risk profile.
Maybe my examples are bording on sabotage, eg "sabotage by accident".
