Ok, not 100%. Human Factors can be critical in a lot of cases. Similar to security, designers try to eliminate the system's reliance on human actions wherever possible.

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.
