Did Shelley Winters Have A Disaster Kit On The Set Of The Poseidon Adventure?

I always wondered if one of the best disaster movies of all time, The Poseidon Adventure, which starred Gene Hackman, Ernest Borgnine, Red Buttons, Roddy McDowell, Stella Stevens, Jack Albertson, Shelley Winters, Leslie Nielsen and Pamela Sue Martin had a couple of disaster kits on hand just in case of an emergency since it was filmed primarily in water where the potential of drowning was extremely possible. With the dangerous swim that Shelley Winters had to perform in the movie, I think having a couple of disaster kits on the set would have been the smart thing to do.
