I'm no lawyer, but I could imagine it being construed as interfering with emergency services if you wound up in a situation where first responders might take it seriously.

It's for static stuff being responded by firefighters to as opposed to DOT placards handling actual hazcom so I don't think you would be cited for improper DOT hazcom.

Where you would run into trouble is if you ever need a first response to your car and the ambulance shows up and the barely educated tech freaks out and requests the fire departments paramedic instead. I think that runs a little pricier and obviously has implications on response time in case you've like had a heart attack on the road.

A combination of combustion, toxicity and explosivity. You could be lit on fire, exposed to something that would like to react with the delicate mechanisims that operate your biology, and finally exposed to a rapidly expanding gas cloud and anything it picked up between you and the source of the explosion.

tert-butyllithium and pentaborane are the only two compounds that I can find that fit 4-4-4, but even then they aren't oxidizers.

Both of those are acutely poisonous compounds that burst into flames when exposed to a wide variety of different substances, such as water or air

I had an idea to make a video about the craziest stuff ever investigated as rocket fuels and I figure the regular posters here might have a few suggestions I’ve missed - my shortlist so far:

Chlorine trifluoride oxidizer
Hydrazine
Fuming nitric acid
Liquid Ozone
Lithium-fluorine-Hydrogen
‘Devils venom’ (nitric acid/hydrazine)
Dimethylmercury
Nitroglycerine

Obviously ‘Ignition’ has many great stories, but it’s 40 years old and who knows what innovation in insanity have transpired in intervening decades.

Is ClF3 a 0 on the toxicity scale because ClF3 is actually not significantly toxic or because it will oxidize into substances so quickly you don't need to worry about its toxicity?

That particular 0 refers instead to flammability. ClF3 is a ludicrous compound that will react with a lot of stuff, but it does so as an oxidizer and thus won't innately burn upon contact with heat. In that respect it's like O2 gas but far less easy to control.

How would you test the toxicity?

Experiment 1: Added ClF3 to mouse food. Result: Food caught fire.
Experiment 2 Added ClF3 to mouse's water. Result: Water caught fire.
Experiment 3: Administered ClF3 to mouse intravenously. Result: Mouse caught fire.

It's a gas so it'd be "make mouse huff it.' Use a chamber made of a metal that readily forms a passive layer.

I should have, but i was phone posting and I wanted to edit the post when i got back home, but then I immediately fell asleep.

I should have also mentioned, it was used in auxilliary rocket booster on Mirage IIIc, before being replaced by kerosene, except Kerosene is not hypergolic with nitric acid, so small amounts were still used as a starter.

Always use premium hypergolic fuel to prevent premature detonation.
