Health Hazards Information -Recommended PersonalprotectveE4uipment: Self-contained breathing
apparatus; safety goggles; Symptoms Following Exposure: Central nervous system depression ranging
from dizziness and incoordination to anesthesia and respiratory arrest, depending on concentrations and
extent of inhalation. Irregular heartbeat is rare but is a dangerous complication at anesthetic levels;
General Treamzent for Exposure: INHALATION: protect victim against self-injure if he is stuporous,
confused, or anesthetized; apply artificial respiration if breathing has stopped; avoid administration of
epinephrine or other sympathomimetic amines; prevent aspiration of vomitus by proper positioning of
head; give symptomatic and supportive treatment. INGESTION OR ASPIRATION no treatment re-
quired; Toxicity by Inhalation (Threshold Limit Value): Data not available; Short-Tenn Inhalation
