Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. May be absorbed through damaged or
abraded skin in harmful amounts.
Ingestion:
Causes gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause central nervous system depression, characterized
by excitement, followed by headache, dizziness, drowsiness, and
nausea. Advanced stages may cause collapse, unconsciousness, coma
and possible death due to respiratory failure. May cause tissue
anoxia, characterized by weakness, headache, dizziness, confusion,
cyanosis (bluish skin due to deficient oxygenation of the blood),
weak and irregular heart beat, collapse, unconsciousness,
convulsions, coma and death.
Inhalation:
May cause respiratory tract irritation.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Chronic
poisoning by boron compounds, borism, may be little more than dry
skin and mucous membranes, followed by appearance of a red tongue,
patchy alopecia (hair loss), cracked lips, and conjunctivitis.
Infants and young children are more susceptible to boric acid
poisoning than adults.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Flush skin with plenty of soap and water for at least 15 minutes
while removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists. Wash clothing before reuse.
Ingestion:
Call a poison control center. If swallowed, do not induce vomiting
unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Get medical aid.
Inhalation:
Get medical aid immediately. Remove from exposure to fresh air
immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen.
Notes to Physician:
Antidote:
None reported.
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear.
Extinguishing Media:
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Avoid generating dusty conditions. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Minimize dust generation and accumulation. Avoid contact with eyes,
skin, and clothing. Keep container tightly closed. Avoid ingestion
and inhalation.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances. Keep containers tightly closed.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Always use
a NIOSH or European Standard EN 149 approved
respirator when necessary.
