Routes of Entry: Inhalation-XX   Skin-XX    Ingestion-XX

Health Hazards(Acute and Chronic):

  Inhalation: Inhalation of mist may cause mild upper

respiratory irritation. May be absorbed from the mucous

membranes.

  Ingestion: A lethal dose of boric acid is 5-30 grams for

an adult. 100 ml of this solution contains no more than 2

grams of boric acid.

  Skin Contact: Boric acid can be absorbed through the skin

with symptoms paralleling those for ingestion.

  Eye Contact: May cause irritation and redness if splashed

in the eyes.

  Chronic Exposure: Prolonged absorption causes weight loss,

vomiting, diarrhea, skin rash, convulsions and anemia.

Kidneys and liver may be particularly susceptible.

Carcinogenicity: NTP-No   IARC Monographs-No    OSHA-No

Signs and Symptoms of Exposure: See "Health Hazards" above.

Medical Conditions Generally Aggravated by Exposure:

  Persons with pre-existing skin disorders or eye problems,

or impaired liver, kidney or respiratory function may be

more susceptible to the effects of this solution.

Emergency and First Aid Procedures:

  Inhalation: If inhaled, remove to fresh air. Give oxygen

for breathing difficulty. Call a physician.

  Ingestion: Get immediate medical attention. Induce

vomiting by giving several glasses of water and sticking

finger down throat. Never give anything by mouth to an

unconscious person.   Skin Contact: Flush with plenty of

water for at least 15 minutes. Open cuts will absorb boric

acid.

  Eye Contact: Flush eyes with plenty of water for at least

15 minutes.
