ETHYLENE OXIDE (5 PPM - 200 PPM) IN NITROGEN

SECTION 2: Hazards identification

EMERGENCY OVERVIEW Release of this product may produce oxygen-deficient atmospheres (especially in confined spaces or other poorly ventilated environments); individuals in such atmospheres may be asphyxiated. Low concentrations of Ethylene Oxide can be irritating to eyes and upper respiratory system: inhalation of low levels of this gas may also cause nausea, vomiting, and numbing of the sense of smell. Additionally, Ethylene Oxide is potentially carcinogenic to humans.

Exposure Limits Irritant Sensitization Reproductive Hazard Mutagen Yes No Yes Carcinogenicity --NTP Yes IARC Yes OSHA Yes EYE EFFECTS: Over-exposure to the eyes may cause irritation (i.e. redness, stinging). SKIN EFFECTS: N/A. 1 INGESTION EFFECTS: Ingestion unlikely. Gas at room temperature. INHALATION EFFECTS: Due to the small size of this cylinder, no unusual health effects from over-exposure are anticipated under normal routine use. The most significant, acute effect associated with a release of this product would be for the potential development of oxygen-deficient atmospheres. If this product is released in a small poorly ventilated area, an oxygen-deficient environment may occur.
