142 DINITROCRESOLS
gloves; protective clothing; Symptoms Following Exposure: Inhalation or ingestion causes loss of color,
nausea, headache, dizziness, drowsiness, and collapse. Eyes are irritated by liquid. Stains skin yellow;
if contact is prolonged, can be absorbed into blood and cause same symptoms as for inhalation; Generd
Treatment for Exposure: INHALATION: remove from exposure; get medical attention for
methemoglobinemia. EYES: flush with water for at least 15 min. SKIN: wash well with soap and
water. INGESTION: induce vomiting, if conscious; give gastric lavage and saline cathartic; get medical
attention; Toxicity by Inhalation (ThresholdLimit Value): 1 mg/m3; Short-Tern Exposure Limits: Data
not available; Toxicity by Ingestion: Grade 4; oral LD,, 42 mg/kg; Late Toxicity: May cause liver
damage, anemia, neuritis; Vapor (Gas) Irritant Characteristics: Data not available; Liquid or Solid

Health Hazards Information - Recommended Personal Protective Equipment: Dust mask; goggles or
face shield; protective clothing; rubber gloves; Symptoms Following Exposure: Very high fever is
prominent sign of intoxication following absorption of a toxic dose of dinitro-o-cresol. Inhalation of
dust may cause same symptoms as ingestion. Ingestion causes a feeling of well-being, profuse sweating,
yellow urine, increased basal metabolism, marked thirst, vomiting, convulsions, coma, and death.
Contact with eyes causes irritation. Contact with skin causes local necrosis and dangerous systemic
effects. Note: Some authorities recommend that all exposed workers have blood tests regularly to
determine the level of this substance. Further contact should be avoided if the level exceeds 20
micrograms per gram; General Treatment for Exposure: INHALATION: apply ice packs to promote
heat loss; replace fluids and electrolytes; allay anxiety. INGESTION: same as for inhalation; also, give
large amounts of water and induce vomiting; get medical attention. EYES: flush with water for at least
15 min. SKIN: wash thoroughly with soap and water; Toxicity by Inhalation (ThreshoMLimit Valw):
0.2 mg/m3; Short-Tern ExpoureLimits: 1 mg/m3, 30 min.; Toxicity by Ingestion: Grade 4; LD,, <SO
mg/kg (rat); Lute Toxicity: Data not available; Vapor (Gas) Irritant Characteristics: Data not available;
Liquid or Solid Irritant Characteristics: Data not available; Odor Threshold Data not available.
