SAFETY PROFILE：
Unsaturated aliphatic hydrocarbons do not differ greatly from paraffins, particularly insofar as their toxic effect on working personnel is concerned. Ethylene and some of its homologs occur in manufactured and natural gases. Ethylene can be used as an anesthetic, and on inhalation in sufficient quantity it can be an asphyxiant. However, the greatest hazard from its use is the danger of fire and explosion. Prolonged or repeated exposures to high concentrations of various olefins have caused certain toxic effects in animals, such as liver damage and hyperplasia of the bone marrow (due to butene-2), but no corresponding effects due to industrial exposures have been discovered in human beings. The diolefins butadiene and isoprene are more irritating than paraffins or mono-olefins of the same volatility. The α-olefins (e.g., 1-octene, 1-octadecene) are particularly reactive because the double bond is on the first carbon. In general the olefins have comparatively low toxicity, but are fire and explosion hazards.
