My research is from real life incidents in non domestic toilets. I will not go into individual cases especially on an AIBU thread but will talk generally. I also look at sexual assaults, being trapped and cleanliness but I will answer your question about rushing to the toilet.
The urge to defecate can be a precursor to cardiac arrest. This is well known. The Valsalva maneuver to force faeces out if constipated puts more pressure on a compromised system as discussed in academic articles which have looked at why this causes many cardiac arrests on the toilet. There’s also academic articles to show survival rates of people after a medical event on a toilet and the factor is whether they are seen to collapse and/or heard.
Nausea is a precursor to many incidents eg. Brain haemorrhage, seizures. When someone thinks they are about to vomit, they head to the nearest toilet because they don’t want to vomit over their desk/ on the shop floor/ over the gym equipment/ over people on the dance floor.
People go to toilets to take illegal drugs, therefore it’s the place people overdose. It’s the most common place for doctors to die from overdoses in a hospital environment.
In schools there’s been a problem with spiked vapes leading to seizures. As far as I know, there’s been no deaths from spiked vapes in school toilets but teachers who have had to do cpr in school corridors have raised the concerns about completely private toilets - where children go to vape. This is from research from Bath University.
People have even died choking to death in restaurant toilets because they start choking and rush to the loo because they are embarrassed. They collapse and people don’t realise until it’s too late, especially when people are drinking and in large groups.
These events add up to many deaths and injuries, some of which have the opportunity to be preventable. Like the one I prevented. I expect she was a fresher at university, and she had had too much to drink in the nightclub, feel sick so went (rushed?) to the toilets without any friends, choked on vomit and stopped breathing. She is alive because as soon as we all entered the Ladies, we immediately saw her because of a 15cm floor to door gap. If it has been an ‘inclusive’ or unisex design it would have been hours before someone was aware. When I have researched other incidents like this in the U.K., the outcome has been different.
The design of a non domestic toilet can make a life or death difference to an occupant at their most vulnerable. It’s irrelevant what gender they are. However, the safest design is one that can only be permitted in a single sex environment. That’s when sex is relevant.
A floor-door gap in a non domestic toilet is similar in function to a car seatbelt. A bit annoying but it’s designed in because if you did need it, it could save your life.
