Section 4 - FIRST AID MEASURES
SWALLOWED
If poisoning occurs, contact a doctor or Poisons Information Centre.
鈥? If swallowed do NOT induce vomiting.
鈥? If vomiting occurs, lean patient forward or place on left side (head-down
position, if possible) to maintain open airway and prevent aspiration.
鈥? Observe the patient carefully.
鈥? Never give liquid to a person showing signs of being sleepy or with reduced
awareness; i.e. becoming unconscious
鈥? Give water to rinse out mouth, then provide liquid slowly and as much as
casualty can comfortably drink.
鈥? Seek medical advice.
EYE
If this product comes in contact with the eyes:
鈥? Wash out immediately with fresh running water.
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? If pain persists or recurs seek medical attention.
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 dust is inhaled, remove from contaminated area.
鈥? Encourage patient to blow nose to ensure clear passage of breathing.
鈥? If irritation or discomfort persists seek medical attention.
NOTES TO PHYSICIAN
For potassium intoxications:
鈥? Hyperkalaemia, in patients with abnormal renal function, results from reduced
renal excretion following intoxication.
鈥? The presence of electrocardiographic evidence of hyperkalemia or serum
potassium levels exceeding 7.5 mE/L indicates a medical emergency requiring an
intravenous line and constant cardiac monitoring.
鈥? The intravenous ingestion of 5-10 ml of 10% calcium gluconate, in adults, over
a 2 minute period antagonises the cardiac and neuromuscular effects. The
duration of action is approximately 1 hour. [Ellenhorn and Barceloux: Medical
Toxicology].

PERSONAL PROTECTION
EYE
鈥? Safety glasses with side shields; or as required,
鈥? Chemical goggles.
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
NIOSH Current Intelligence Bulletin 59].

ENGINEERING CONTROLS
General exhaust is adequate under normal operating conditions. If risk of
overexposure exists, wear SAA approved respirator. Correct fit is essential to
obtain adequate protection. Provide adequate ventilation in warehouse or closed
storage areas. Air contaminants generated in the workplace possess varying
"escape" velocities which, in turn, determine the "capture velocities" of fresh
circulating air required to effectively remove the contaminant.
Type of Contaminant: Air Speed:
solvent " "vapours " degreasing "etc. 0.25-0.5 m/s (50-100 f/min)
" evaporating from tank (in still air)
aerosols " fumes from pouring 0.5-1 m/s (100-200 f/min.)
"operations " intermittent container
"filling " low speed conveyer
"transfers " "welding " spray "drift "
plating acid "fumes " pickling
(released at low velocity into zone of
active generation)
direct "spray " spray painting in 1-2.5 m/s (200-500 f/min)
shallow "booths " drum "filling "
conveyer "loading " crusher "dusts "
gas discharge (active generation into
zone of rapid air motion)
grinding " abrasive "blasting " 2.5-10 m/s (500-2000 f/min.)
"tumbling " high 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:
Lower end of the range Upper end of the range
1: Room air currents minimal or 1: Disturbing room air currents
favourable to capture
2: Contaminants of low toxicity or of 2: Contaminants of high toxicity

motion
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 1-2 m/s (200-400 f/min.) for
extraction of solvents generated in a tank 2 meters 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.

POTENTIAL HEALTH EFFECTS
ACUTE HEALTH EFFECTS
SWALLOWED
The material is moderately discomforting to the gastro-intestinal tract and may
be harmful if swallowed in large quantity Sulfate salts are poorly absorbed from
the gastro-intestinal tract but because of osmotic activity are able to draw
water from the lumen to produce diarrhoea (purging). Sulfate ion usually has
little toxicological potential.

A317TC CD 2006/2 Page 8 of 9
Section 11 - TOXICOLOGICAL INFORMATION
Acute potassium poisoning after swallowing is rare, because vomiting usually
occurs and renal excretion is fast. Potassium causes a slow, weak pulse,
irregularities in heart rhythm, heart block and an eventual fall in blood
pressure. Breathing initially becomes faster but the muscles of breathing
eventually become paralysed. There can be loss of appetite, extreme thirst,
increased volumes of urine, fever, convulsions and gastric disturbances; death
may then occur due to failure of breathing and inflammation of the stomach and
bowel.
EYE
The dust may produce eye discomfort causing smarting, pain and redness.
SKIN
The material may be mildly discomforting to the skin.
Open cuts, abraded or irritated skin should not be exposed to this material.
The material may accentuate any pre-existing skin condition.
INHALED
The dust may be discomforting to the upper respiratory tract.
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 by accidental skin and eye contact and
inhalation of generated dusts. No human exposure data available. For this reason
health effects described are based on experience with chemically related
materials. As with any chemical product, contact with unprotected bare skin;
inhalation of vapour, mist or dust in work place atmosphere; or ingestion in any
form, should be avoided by observing good occupational work practice.
