health hazards acute and chronic: dizziness, headache, mild gastric
symptoms, & (in high concentrations) unconsciousness, and death due
to the reduction of the oxygen level in air below that required to

effects of overexposure: hlth haz: before suffocation could occur, the
lower flamm limit of acetylene in air would be exceeded; poss
causing both an o*2-deficient & an explo atmosphere. Acetylene is
simple asphyxiant & anesthe tic. As narcotic gas/intoxicant, it
