From activities I've undertaken where safety is genuinely the top priority—including aviation,
Not sure it is appropriate to this thread, but i have posted similar comparisons - makes the FAA ("we're not happy until you're not happy" ) seem benign and their materials & trainings scintillating, memorable, accessible, (and of course free). FSDO will send a Tech or Rep any mutually convenient time your group wants to schedule, on any Av related subject, safety especially, on their dime. My inbox receives webinar options for trainings several times/week as well as notices of on-site seminars at local facilities within about 100 mi radius.
Safety training has to be thorough enough that an incident - almost any incident - provokes a series of effective, rote responses.
Matrix for decision about reporting requirements.
Clear expectations supported by clear, routinely updated, and culturally reviewed materials and resources for same.
IME, the best safety enhancer would be an effective means to sort & prevent people who are out of control on most of their runs.
However, this would be antithetical to ski area financial interests. I don't think it is exaggerating to guess that close to 1/4 & possibly as many as 1/3 of skiers on black and steep blue groomers can't efficiently control their speed or turn shape and incidence . But nobody is going to want to ski at an area that makes skiing sedate, or gets a rep for being "fascist".
Again, necessary subject we all need to work toward. But a digression to the thread topic.
