Health Hazards Information - Recommended Personal Protective Equipment: Protective respirator;
rubber gloves; clean clothes; Symptom Following Exposure: Inhalation of dust causes irritability,
tremors, and collapse. Ingestion causes nausea, vomiting, diarrhea, and irritation of the gastrointestinal
tract. Contact with dust causes irritation of eyes and moderate irritation of skin; General Treatment for
Exposure: Get medical attention following all overexposure to heptachlor. INHALATION: move to
fresh air; if exposure to dust was severe, get medical attention. INGESTION: lavage stomach with
warm tap water (unless convulsions are imminent); fats and oils should be avoided, as they increase
the rate of absorption of all chlorinated hydrocarbons. EYES: wash repeatedly with water. SKIN: flush
with water, then wash with soap and water; Toxicity by Inhalation (ThresholdLimit Value): 0.5 mg/m3;
Short-Term Inhalation Limits: 2 mg/m3 for 30 min.; Toxicity by Ingestion: Grade 4; oral LD, = 40
mg/kg (rat); Late Toxicity: Liver damage may develop; Vapor (Gas) Irritant Characteristics: Data not
available; Liquid or Solid Im'tant Characteristics: Data not available; Odor lbeshold 0.02 ppm.
Fire Hazards - Flash Point : Not flammable; Flammble Limits in Air (%): Not flammable; Fire
Extinguishing Agents: Not pertinent; Fire Extinguishing Agents Not To Be Used: Not pertinent; Special
Hazards of Combustion Products: Irritating and toxic hydrogen chloride fumes may form in fires;
Behavior in Fire: No data; Ignition Temperature : Not pertinent; Electrical Hazard: Not pertinent;
Burning Rate: Not pertinent.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common MateriaLs: No
reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent;
Polymerizalion: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Health Hazards Information - Recommended Personal Protective Equipment: Safety glasses; gloves;
similar to gasoline; Symptoms Following Exposure: INHALATION irritation of respiratory tract,
coughing, depression, cardiac arrhythmia. ASPIRATION: severe lung irritation, pulmonary edema,
mild excitement followed by depression. INGESTION nausea, vomiting, swelling of abdomen,
depression, headache; General Treatment for Exposure: INHALATION: maintain respiration; give
oxygen if needed. ASPIRATION: enforce bed rest; administer oxygen. INGESTION: do not induce
vomiting. SKIN OR EYES: remove contaminated clothing, wipe and wash skin area with soap and
water; wash eyes with plenty of water; Toxicity by Inhalation (Threshold Limit Value) : 500 ppm; Short-
Term Inhalation Limits: 500 ppm for 30 min. ; Toxicity by Ingestion: Grade 0; LD,, above 15 glkg; Lute
Toxicity: None; Vapor (Gas) Irritant Characteristics: Vapors are nonirritating to the eyes and throat;
Liquid or Solidlrritant Characteristics: Minimum hazard. If spilled on clothing and allowed to remain,
may cause smarting and reddening of the skin; Odor Threshold: 220 ppm.
