Sure. Even a history of safety success contributes to this. We haven't had an accident in 3000 days, what was dangerous about this job again? Also what's this stupid policy for anyway, I've never seen anybody even come close to (non-dangerous-sounding fate) while working here.

But probably the policy is in place because it used to happen before the policy was in place. It's just not obvious to people who have never seen the consequences before.
