Considering there are no antidotes to most toxins that come from most marine organisms I really wonder what an adequate sum would be. It is one thing to get a little coral slime in a scratch or cut, but to have that some mucous or even worse chemical toxins applied directly to highly absorbent oral tissues seems like more risk than I would want to take. There are not a lot of people in an average home that no how to do a tracheotomy or put in an intubation tube before someones windpipe fully closes. I doubt even many homes have epinephrine for allergic reactions such as would be used for bee stings. Nope, I would not do it, even if sitting in a vehicle in an emergency room parking lot. It is doubtful a hospital in midwest U.S.A would think to stock any antitoxins for marine toxins anyway.
