Section 4 - FIRST AID MEASURES
SWALLOWED
路 IF SWALLOWED, REFER FOR MEDICAL ATTENTION, WHERE POSSIBLE, WITHOUT DELAY.
路 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:
路 Induce vomiting with fingers down the back of the of the throat, ONLY IF CONSCIOUS.
路 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.
路 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.
路 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.
路 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:
路 Immediately hold eyelids apart and flush the eye continuously with running water.
路 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.
路 Continue flushing until advised to stop by the Poisons Information Centre or a doctor,
or for at least 15 minutes.
路 Transport to hospital or doctor without delay.
路 Removal of contact lenses after an eye injury should only be undertaken by skilled
personnel.
SKIN
If skin or hair contact occurs:
路 Flush skin and hair with running water (and soap if available).
路 Seek medical attention in event of irritation.
INHALED
路 If fumes or combustion products are inhaled remove from contaminated area.
路 Lay patient down. Keep warm and rested.
路 Prostheses such as false teeth, which may block airway, should be removed, where
possible, prior to initiating first aid procedures.
路 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.
路 Transport to hospital, or doctor.
NOTES TO PHYSICIAN
For acute or repeated short term exposures to boron and its compounds:
路 Nausea, vomiting, diarrhoea and epigastric pain, haematemesis and blue-green
discolouration of both faeces and vomitus characterise adult boron intoxication.
路 Access and correct any abnormalities found in airway and circulation.
路 A tidal volume of 10-15 mg/kg should be maintained.
路 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.
路 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).
路 Peritoneal dialysis and haemodialysis remove some borates.

MATERIAL DATA
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/m3 for the
anhydrous and pentahydrate forms and 5 mg/m3 for the decahydrate is thought
to be protective against the acute irritant effects.
PERSONAL PROTECTION
EYE
路 Safety glasses with side shields; or as required,
路 Chemical goggles.
路 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

ENGINEERING CONTROLS
路 Local exhaust ventilation is required where solids are handled as powders or crystals;
even when particulates are relatively large, a certain proportion will be powdered by
mutual friction.
路 Exhaust ventilation should be designed to prevent accumulation and recirculation of
particulates in the workplace.
路 If in spite of local exhaust an adverse concentration of the substance in air could
occur, respiratory protection should be considered. Such protection might consist of:
(a): particle dust respirators, if necessary, combined with an absorption cartridge;
(b): filter respirators with absorption cartridge or canister of the right type;
(c): fresh-air hoods or masks
路 Build-up of electrostatic charge on the dust particle, may be prevented by bonding and
grounding.
路 Powder handling equipment such as dust collectors, dryers and mills may require
additional protection measures such as explosion venting.
Air contaminants generated in the workplace possess varying "escape" velocities which, in
turn, determine the "capture velocities" of fresh circulating air required to efficiently
remove the contaminant.
Type of Contaminant: Air Speed:
direct spray, spray painting in shallow booths, 1- 2.5 m/s (200- 500 f/min.)
drum filling, conveyer loading, crusher dusts,
gas discharge (active generation into zone of
rapid air motion)
grinding, abrasive blasting, tumbling, high 2.5- 10 m/s (500- 2000 f/min.)
speed wheel generated dusts (released at high
initial velocity into zone of very high rapid
air motion).
Within each range the appropriate value depends on:

Simple theory shows that air velocity falls rapidly with distance away from the opening
of a simple extraction pipe. Velocity generally decreases with the square of distance
from the extraction point (in simple cases). Therefore the air speed at the extraction
point should be adjusted, accordingly, after reference to distance from the contaminating
source. The air velocity at the extraction fan, for example, should be a minimum of 4-10
m/s (800-2000 f/min) for extraction of crusher dusts generated 2 metres distant from the
extraction point. Other mechanical considerations, producing performance deficits within
the extraction apparatus, make it essential that theoretical air velocities are
multiplied by factors of 10 or more when extraction systems are installed or used.
