EMERGENCY OVERVIEW
************************************************************************
* Colorless liquid. Irritating odor. Toxic fumes are released in *
* fire situations. Causes skin irritation. Harmful if inhaled. *
* Can cause death if too much is breathed. Clear all personnel *
* from area. Wear full protected equipment. Contain liquid to *
* prevent contamination of soil, surface water or ground water. *
************************************************************************
POTENTIAL HEALTH EFFECTS (See Section 11 for toxicological data.)
EYE: May cause pain. May cause slight transient (temporary) eye
irritation. Vapors may irritate the eyes at about 100 ppm
perchloroethylene.
SKIN: Short single exposure may cause skin irritation. Prolonged
or repeated exposure may cause severe skin irritation,
even a burn. Repeated contact may cause drying or flaking
of skin. A single prolonged exposure is not likely to result
in the material being absorbed through skin in harmful
amounts. Did not cause allergic skin reactions when tested
in guinea pigs.
INGESTION: Single dose oral toxicity is considered to be
extremely low. Small amounts swallowed incidental to normal

————————————————————————
handling operations are not likely to cause injury; swallowing
amounts larger than that may cause injury. If aspirated
(liquid enters the lung), may be rapidly absorbed through
the lungs and result in injury to other body systems.
INHALATION: In confined or poorly ventilated areas vapors can
readily accumulate and can cause unconsciousness and death.
Dizziness may occur at 200 ppm perchloroethylene; progressively
higher levels may also cause nasal irritation, nausea, incoordi-
nation, drunkenness; and over 1000 ppm, unconsciousness and
death. A single brief (minutes) inhalation exposure to levels
above 6000 ppm perchloroethylene may be immediately fatal.
Based on structural analogy and/or equivocal data in animals,
excessive exposure may potentially increase sensitivity to
epinephrine and increase myocardial irritability (irregular
heartbeats). Alcohol consumed before or after exposure may
increase adverse effects.
SYSTEMIC (OTHER TARGET ORGAN) EFFECTS: Signs and symptoms of
excessive exposure may be central nervous system effects and
anesthetic or narcotic effects. Observations in animals include
liver and kidney effects.
CANCER INFORMATION: For hazard communication purposes under OSHA
Standard 29 CFR Part 1910.1200, this chemical is listed as a
potential carcinogen by IARC and NTP. Perchloroethylene has
been shown to increase the incidence of tumors in certain
strains of mice and rats. Other long-term inhalation studies
in rats failed to show tumorigenic response. Human data are
limited and have not established an association between
perchloroethylene exposure and cancer. Perchloroethylene
is not believed to pose a measurable carcinogenic risk to
man when handled as recommended.
TERATOLOGY (BIRTH DEFECTS): Birth defects are unlikely.
Exposures having no effect on the mother should have no effect
on the fetus. Did not cause birth defects in animals; other
effects were seen in the fetus only at doses which caused toxic
effects to the mother.
REPRODUCTIVE EFFECTS: In laboratory animal studies, effects on
reproduction have been seen only at doses that produced
significant toxicity to the parent animals. In animal studies,
has been shown not to interfere with fertility.

————————————————————————
EYE: Flush eyes with plenty of water.
SKIN: Wash off in flowing water or shower.
INGESTION: Do not induce vomiting. Call a physician and/or
transport to emergency facility immediately.
INHALATION: Remove to fresh air. If not breathing, give
artificial respiration. If breathing is difficult, oxygen
should be administered by qualified personnel. Call a physician
or transport to a medical facility.
NOTE TO PHYSICIAN: Because rapid absorption may occur through
lungs if aspirated and cause systemic effects, the decision of
whether to induce vomiting or not should be made by a
physician. If lavage is performed, suggest endotracheal and/or
esophageal control. Danger from lung aspiration must be
weighed against toxicity when considering emptying the stomach.
If burn is present, treat as any thermal burn, after
decontamination. Exposure may increase “myocardial
irritability”. Do not administer sympathomimetic drugs unless
absolutely necessary. No specific antidote. Supportive care.
Treatment based on judgment of the physician in response to
reactions of the patient.
