HEALTH HAZARD AND FIRST AID DATA
________________________________________________________________
PRIMARY ROUTE(S) OF ENTRY: Inhalation and ingestion. Eye
contact. Skin contact. Skin
absorption.
EFFECTS OF ACUTE EXPOSURE:
Harmful by ingestion, inhalation or skin absorption.
Irritant. LC50: Not available
LD50: ORL-Rat 2660 mg/kg
EYES: Causes irritation.
SKIN: Causes skin irritation. May cause desquamation. Can
be absorbed through damaged skin causing symptoms
similar to ingestion.
INHALATION: Causes respiratory tract irritation. Irritating to the
mucous membranes. See ingestion.
INGESTION:
Causes gastrointestinal irritation. May cause central nervous
system depression, (headache, nausea, vomiting, dizziness,
abdominal pain, etc...) diarrhea, oliguria, anuria, erythema,
mascular rash, kidney damage, cardiovascular collapse, shock and
death if ingested in large amounts. Toxic effects may be
delayed.
EFFECTS OF CHRONIC OVEREXPOSURE:
May cause nose irritation, dyspnea, abdominal pain, reversible
erythema and/or rash, central nervous system effects, dizziness,
macular rash and lung damage. Animal studies show that ingestion
of large amounts of borates over prolonged periods of time cause
a decrease in sperm production and testicle size in male
laboratory animals and developmental effects of fetuses of
pregnant female laboratory animals.
TERATOGEN (yes); REPRODUCTIVE TOXIN (yes); Not fully investigated.
FIRST AID:
EYES: Wash eyes and skin with copious quantities of water for
at least 15 minutes. Call a physician.
SKIN: Remove contaminated clothing. Wash skin with soap and
water. Call a physician. Wash clothing before reuse.
INHALATION: Remove patient to fresh air. Administer artificial
respiration or CPR if breathing has ceased. Call a
physician.
3
INGESTION: Induce vomiting. Give large quantities of water or
milk. Get immediate medical attention. Never
give anything by mouth to an unconscious person.

Wear dust mask. If more than TLV, do not breathe vapor. Wear
appropriate OSHA/MSHA approved chemical cartridge respirator.
VENTILATION: Adequate ventilation to maintain vapor/dust below TLV.
SKIN PROTECTION: Impervious gloves. Apron or clothing to protect
skin. Sufficient to protect skin.
EYE PROTECTION: Safety goggles.
OTHER PROTECTIVE EQUIPMENT: Make eye bath and emergency shower
available.
SPILLAGE OR LEAKS PROCEDURES:

SPECIAL PRECAUTIONS OR COMMENTS
________________________________________________________________
Teratogen!!! Reproductive Toxin!!! Irritant! Do not breathe
dust. Avoid all contact with the product. Avoid prolonged or
repeated exposure. Use adequate ventilation.
NOTES TO PHYSICIAN:
Gastric lavage with 5% sodium Bicarbonate is suggested. This
should be followed by saline catharsis. Assure adequate
hydration. Borax is not considered an acute poison. After
ingestion or absorption into the bloodstream of large amounts (15
grams or more), symptoms may appear after 24-72 hours. Borates
are readily dissipated through the urine (70% in the first 24
hours).
