A fatal laboratory accident with toxic gases inhalation.

Three university students were exposed to toxic vapours (acryloyl chloride 96% and methacrylic anhydride 94%) in a laboratory accident. They all gave a history of minimal exposure and presented with mild symptoms. One patient died on the same day. The other two cases were uneventful. This paper reports on these three cases, followed by a discussion on irritant gas intoxication.
