I took one photo that I did not prepare this blog, zoomed in and noticed it was carrying a substance called butadiene. According to wikipedia, butadiene is mainly used to produce synthetic rubber.
Most butadiene is polymerized to produce synthetic rubber. Acute exposure results in irritation of the mucous membranes, Higher levels can result in neurological effects such as blurred vision, fatigue, headache and vertigo. Exposure to the skin can lead to frostbite. (Source: Wikipedia)
Nasty but useful stuff, I guess.
