NIOSH Registry of Toxic Effects of Chemical Substances (RTECS) Identification Number: KU5340000

Chemical Description and Physical Properties:

colorless compressed gas, with characteristic odor
molecular weight: 28.00
vapor pressure: 8100 kPa at 15°C
molecular formula: C2H4
boiling point: -104°C

Incompatibilities: Reacts with strong oxidants causing fire and explosion hazard. Reacts violently with aluminum chloride, benzoyl peroxide and carbon tetrachloride, bromotrichloromethane, carbon tetrachloride, chlorine, chlorine dioxide, nitrogen dioxide, nitromethane and aluminum chloride, and ozone.

Exposure Limits

OSHA Permissible Exposure Limit (PEL):

Maritime: 29 CFR 1915.1000 Table Z-Shipyards -- Simple Asphyxiants. The limiting factor is the available oxygen which shall be at least 18 percent and be within the requirements addressing explosion in subpart B of part 1915.

American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): Simple Asphyxiant; Appendix A4 - Not Classifiable as a Human Carcinogen

Health Factors

Carcinogenic Classification:

International Agency for Research on Cancer (IARC): Group 3, not classifiable as to its carcinogenicity to humans

Potential Symptoms: Drowsiness; unconsciousness

Health Effects: Simple asphyxiant (HE17); Explosive (HE18)

Notes:

  1. Metabolized to ethylene oxide, a known carcinogen, which forms 2-hydroxyethyl adducts with hemoglobin and DNA. However, the health effects of long-term or repeated exposure to ethylene are not known.
