ISOPHTFIALIC ACID 221
Not pertinent.
Health Hazards Information - Recommended Personal Protective Equipment: Self-contained breathing
apparatus with full face mask; rubber gloves; Symptoms Following Exposure: Inhalation irritates eye,
nose and throat; causes central depression and has some anesthetic effect. Contact of liquid with eyes
causes severe irritation and possible tissue damage. Skin is irritated by liquid and may crack on
prolonged contact. Ingestion causes irritation of mouth and stomach; General Treatment for Exposure:
INHALATION remove victim promptly from contaminated atmosphere; if breathing has stopped, give
artificial respiration and oxygen. EYES: flood with water for at least 15 min.; consult an eye specialist
as soon as possible. SKIN: flood with water. INGESTION: do not induce vomiting; call a doctor;
Toxicity by Inhalation (Threshold Limit Value): 10 ppm; Short-Term Inhalation Limits: Data not
available; Toxicity by Ingestion: Grade 2; oral LD,, = 2,330 mg/kg (rat); Lute Toxicity: Data not
available; Vapor (Gas) Irritant Characteristics: Vapors cause moderate irritation such that personnel
will find high concentrations unpleasant. The effect is temporary; Liquid or Solid Irritant
Characteristics: Causes smarting of the skin and first-degree burns on short exposure; may cause
secondary burns on long exposure; Odor ZRreshold Data not available.
Fire Hazards - Fhh Point (deg. F): 205 OC, 184 CC; Flammable Limits in Air (%): 0.84 - 3.8; Fire

Health Hazards Information - Recommended Personal Protective Equipment: If without adequate
ventilation, use respirator with dust filter, goggles, and gloves; Symptoms Following Exposure: May
cause slight to moderate irritation of eyes, skin, and mucous membranes on prolonged contact.
Ingestion may cause gastrointestinal irritation; General Treatment for Exposure: INHALATION:
remove victim to uncontaminated area; get medical attention if complications arise. INGESTION: get
medical attention if complications arise. EYES: flush with large amounts of water for 15 min.; get
promptly medical attention. SKIN: wash with water; Toxicity by Inhalation (Threshold Limit Value):
