I completely disagree, though, you're not getting my point. There is a type of "standard" warning that I routinely ignore, the "don't cut yourself with the tablesaw" warnings. Or "knife is sharp". Like, yeah, that's why I'm using the knife.
A warning I won't ignore is one written by a friend about something unusual or unexpected. "The supposedly insulated handle on this pot will melt your fingers off"
I just think that comic sans draws my eye in, in a way that Copperplate instructions from HR do not. Don't tell HR, or they'll start using Comic Sans.
These are fonts that are not just eye-catching, but actively painful to look at for how striking they are, to the point that they're even maybe a bit hard to read (but you still end up reading them, because it's hard to look away.) These are fonts that scream at you — fonts HR would never dare to use, even knowing they "work", because it'd be unprofessional to be that attention-grabbing. It'd be the typographic equivalent of blowing an airhorn in a small room in order to interrupt someone.
(Though actually, oddly enough, something about that typography makes me feel threatened even without the image. I think that particular tight leading with all-caps lettering using a high-weight sans-serif font, puts me in mind of specific public civic-engineering uses of typography to warn people away from high-voltage power substations, large AM radio transmitters, hydro-dam spillways, etc. It's a subtle thing, but it's enough to make it really not look like your standard HR print-out.

Seeing that on something is just unsettling — for purely typographic reasons!)
