This method is so corrosive and toxic that they have to send rescue workers in with complete hazmat suits. Think of the movie the Hot Zone. When they come out they have to be decontaminated with a firehose spraying them down before they can take the suit off.
It may be effective, but it is painful and a hazard to anyone that comes to rescue you without proper gear. You could take out an ambulance or fire department easily. If contemplating this, you need to post warning signs all over the vehicle or residence so they don't smash a window or break down a door to get to you contaminating them. Emergency workers expect to go home at the end of their shift, not in a bodybag.
There was an article somewhere about a kid in Japan in an apartment building that did this and almost 100 people were sick because of it. In the US, it seems most do this in a vehicle. IDK why, but it would guarantee you are the only person with the effects if you were to be in a more isolated place. But, the notes all over your car are going to tip someone off. This made its way to the US around 2015, and responders didn't know what it was as they were smashing glass to get to the person, thus causing them harm. On first glance, a bottle of detergent and a pesticide container look harmless enough if you don't also look for a bucket or bowl with fluids in it. The hydrogen sulfide is colorless. You MIGHT smell rotting eggs, but cars today are so tightly sealed up that they may not leak it outside. And, if they are wearing N95 routinely now due to COVID, they might not smell it.
