INHALATION: High concentration of vapor will produce irritation of the respiratory tract and the lungs. Prolonged exposure may cause systemic effects. EYES: Contact with liquid may result in severe eye irritation. Exposure to concentrated vapor may result in corneal edema. SKIN: Contact with liquid may result in severe skin irritation, burns and possible skin absorption. INGESTION: May cause systemic poisoning. (USCG, 1999)

· May cause toxic effects if inhaled or ingested.

Reactivity Profile · 1 Eintrag

2-ETHYLHEXYLAMINE reacts with oxidizing materials (NTP, 1992). Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.

First Aid · 2 Einträge

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
