Section 4 - FIRST AID MEASURES
SWALLOWED
If poisoning occurs, contact a doctor or Poisons Information Centre.
鈥? IF SWALLOWED, REFER FOR MEDICAL ATTENTION, WHERE POSSIBLE, WITHOUT DELAY.
鈥? For advice, contact a Poisons Information Centre or a doctor.
Where Medical attention is not immediately available or where the patient is
more than 15 minutes from a hospital or unless instructed otherwise:
鈥? Induce vomiting with fingers down the back of the of the throat, ONLY IF
CONSCIOUS.
鈥? Lean patient forward or place on left side (head-down position if possible) to
maintain open airway and prevent aspiration.
NOTE: Wear a protective glove when inducing vomiting by mechanical means.
鈥? In the mean time, qualified first-aid personnel should treat the patient
following observation and employing supportive measures as indicated by the
patient's condition.
鈥? If the services of a medical officer or medical doctor are readily available,
the patient should be placed in his/her care and a copy of the MSDS should be
provided. Further action will be the responsibility of the medical specialist.
鈥? If medical attention is not available on the worksite or surroundings send the
patient to a hospital together with a copy of the MSDS.
EYE
If this product comes in contact with the eyes:
鈥? Immediately hold eyelids apart and flush the eye continuously with running
water.

Section 4 - FIRST AID MEASURES
鈥? Ensure complete irrigation of the eye by keeping eyelids apart and away from
eye and moving the eyelids by occasionally lifting the upper and lower lids.
鈥? Continue flushing until advised to stop by the Poisons Information Centre or a
doctor, or for at least 15 minutes.
鈥? Transport to hospital or doctor without delay.
鈥? Removal of contact lenses after an eye injury should only be undertaken by
skilled personnel.
SKIN
If skin or hair contact occurs:
鈥? Flush skin and hair with running water (and soap if available).
鈥? Seek medical attention in event of irritation.
INHALED
鈥? If fumes or combustion products are inhaled remove from contaminated area.
鈥? Lay patient down. Keep warm and rested.
鈥? Prostheses such as false teeth, which may block airway, should be removed,
where possible, prior to initiating first aid procedures.
鈥? Apply artificial respiration if not breathing, preferably with a demand valve
resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if
necessary.
鈥? Transport to hospital, or doctor.
NOTES TO PHYSICIAN
For acute or repeated short term exposures to boron and its compounds:
鈥? Nausea, vomiting, diarrhoea and epigastric pain, haematemesis and blue-green
discolouration of both faeces and vomitus characterise adult boron intoxication.
鈥? Access and correct any abnormalities found in airway and circulation.
鈥? A tidal volume of 10-15 mg/kg should be maintained.
鈥? Emesis should be induced unless the patient is in coma, is experiencing
seizures or has lost the gag reflex. If any of these are present, gastric lavage
should be performed with a large-bore tube after endotracheal intubation or in
the presence of continuous respiratory action.
鈥? Activated charcoal is probably not of value though its use might be indicated
following gastric evacuation. Catharsis might be useful to eliminate any borates
remaining in the gastro-intestinal tract (magnesium sulfate: adults, 30 gms:
children 250 mg/kg).
鈥? Peritoneal dialysis and haemodialysis remove some borates.

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
No data are currently available to establish a causal link between
inhalation exposures to sodium tetraborates and chronic respiratory and/or
systemic effects.
An occupationally important toxic effect of the sodium tetraborates is
their acute irritant effect when in contact with skin and the mucous
membranes of the eyes, nose and other sites of the respiratory tract.
The irritant properties increase with decreasing water of hydration due
to the exothermic effect of hydration. The TLV-TWA of 1 mg/m鲁 for the
anhydrous and pentahydrate forms and 5 mg/m鲁 for the decahydrate is thought
to be protective against the acute irritant effects.
PERSONAL PROTECTION
EYE
鈥? Safety glasses.
鈥? Contact lenses may pose a special hazard; soft contact lenses may absorb and
concentrate irritants. A written policy document, describing the wearing of lens
or restrictions on use, should be created for each workplace or task. This
should include a review of lens absorption and adsorption for the class of
chemicals in use and an account of injury experience. Medical and first-aid
personnel should be trained in their removal and suitable equipment should be
readily available. In the event of chemical exposure, begin eye irrigation
immediately and remove contact lens as soon as practicable. Lens should be
removed at the first signs of eye redness or irritation - lens should be removed
in a clean environment only after workers have washed hands thoroughly. [CDC

POTENTIAL HEALTH EFFECTS
ACUTE HEALTH EFFECTS
SWALLOWED
The material is highly discomforting to the gastro-intestinal tract may cause
severe mucous membrane damage and may be harmful if swallowed in large quantity
Individuals vary greatly in their susceptibility to poisoning and symptoms may
appear after a few weeks or many years of exposure.
Considered an unlikely route of entry in commercial/industrial environments.
Borate poisoning causes nausea, vomiting, diarrhoea and pain in the upper
abdomen. Often persistent vomiting occurs, and there may be blood in the faeces.
There may also be weakness, lethargy, headache, restlessness, tremors and
convulsions. All borates cause similar effects; the lethal dose is over 30
grams. Poisoning initially stimulates the central nervous system before causing
depression, as well as disturbing the digestive system, causing skin eruptions,
and damage to the liver and kidneys. Borate is mostly eliminated from the body
via the kidneys.
EYE
The material is highly discomforting to the eyes and is capable of causing pain

and severe conjunctivitis. Corneal injury may develop, with possible permanent
impairment of vision, if not promptly and adequately treated.
SKIN
The material is moderately discomforting to the skin and is capable of causing
skin reactions which may lead to dermatitis.
Solution of material in moisture on the skin, or perspiration, may increase
irritant effects.
Prolonged exposure may cause chemical burns.
Open cuts, abraded or irritated skin should not be exposed to this material.
INHALED
The dust may be highly discomforting to the upper respiratory tract may cause
severe mucous membrane damage and may be harmful if inhaled.
Inhalation of small amounts of dust or fume over long periods may cause
poisoning.
Persons with impaired respiratory function, airway diseases and conditions such
as emphysema or chronic bronchitis, may incur further disability if excessive
concentrations of particulate are inhaled.
CHRONIC HEALTH EFFECTS
Principal routes of exposure are usually by. inhalation of generated dust and
inhalation of fumes from the heated material. Borate can accumulate in the
testes and deplete germ cells and cause withering of the testicles, according to
animal testing. Hair loss, skin inflammation, stomach ulcer and anaemia can all
occur. Repeated swallowing or inhalation irritates the stomach, causes a loss of
appetite, disturbed digestion, nausea and vomiting, red rash, dry skin and
mucous membranes, reddening of the tongue, cracking of the lips, inflamed
conjunctiva, swelling of the eyelids and kidney injury. Animal testing revealed
prolonged ingestion causes effects to the reproductive system in both males and
females.
