There are better ways to be covered without having a nurses station and paying $25 per hour. Actors in a small haunt know how to offer some assistance, you even have little course if necessary. Or for a little larger deal, you have your own security staff, kind of inspired by the Las Vegas casino thing. They might make $10 an hour and are yours with the intention of just getting help in a timely manner. Mostly their job is to direct people to the exits or onward to the next section of entertainment. Kind of like store keeper just say hello so shopp lifters may chose not to strike since they have been aknowledged.
Some may already be people with those skills but that isn't thier special intent.
I have had about 3 younger girls a year go from the first room into something else that caused asthma attacks and hyperventilation. So the only way to restore their breathing was with oxygen bottles and people that knew where and what oxygen bottles were for. Some didn't have their little spray bottle, others had no idea they had a problem like that. It wasn't fog machines, it was just too many things happening at one time going from a regular room to dark odd shaped hallways.
Actual injuries are actually very low in a poll of lots of haunted houses. Fire people and security people tend to overlap these skills rather than having an ambulance on standby like an Evil Kenevil jump where someone is definitely going to get messed up.
Another fabulous post from the U.S.Department of Wild Imaginings, now in spectaclar stereo, sponsored by the Adhesives and Sealants Council, suggesting ways to stick things together since the 1800s. Not fabulous in a gay way. Your results may vary. Illinois residents add 8% sales tax.
