Interesting story unfortunately this MSDS was in circulation since (I thought) 1994 so you have not told us much new.
What may be interesting is your local poison centre's expression of
"sudden death" try to get a statement on paper.They may have looked in George Gobles website (www.autofrost.com).
If you do same you may learn a lot more about refrigerant toxicity in general and r134a in particular.
NB R134a is only flammable at the conditions you stipulated + oxygin and spark.
NB Anybody able to direct me to Toxicity studies (min 150 pages) of R134a, have so far not seen any of them. Recent TNO study Netherlands
is as far as I know not yet released to customers "Elf Atochem et al"
but small publications predict --no harm when using R134 within the 1000 ppm limit.
