Section 4 - FIRST AID MEASURES
SWALLOWED
路 Immediately give a glass of water.
路 First aid is not generally required. If in doubt, contact a Poisons Information Centre
or a doctor.
EYE
If this product comes in contact with the eyes:
路 Wash out immediately with fresh 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 If pain persists or recurs seek medical attention.
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 dust is inhaled, remove from contaminated area.
路 Encourage patient to blow nose to ensure clear passage of breathing.
路 If irritation or discomfort persists seek medical attention.
路 If fumes or combustion products are inhaled remove from contaminated area.
路 Other measures are usually unnecessary.
NOTES TO PHYSICIAN
For potassium intoxications:
路 Hyperkalaemia, in patients with abnormal renal function, results from reduced renal
excretion following intoxication.
路 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.
路 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].

MATERIAL DATA
These "dusts" have little adverse effect on the lungs and do not produce toxic effects or
organic disease. Although there is no dust which does not evoke some cellular response at
sufficiently high concentrations, the cellular response caused by P.N.O.C.s has the
following characteristics:

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
路 scar tissue (collagen) is not synthesised to any degree,
路 tissue reaction is potentially reversible.
Extensive concentrations of P.N.O.C.s may:
路 seriously reduce visibility,
路 cause unpleasant deposits in the eyes, ears and nasal passages,
路 contribute to skin or mucous membrane injury by chemical or mechanical action, per se,
or by the rigorous skin cleansing procedures necessary for their removal. [ACGIH]
This limit does not apply:
路 to brief exposures to higher concentrations
路 nor does it apply to those substances that may cause physiological impairment at lower
concentrations but for which a TLV has as yet to be determined.
This exposure standard applies to particles which
路 are insoluble or poorly soluble* in water or, preferably, in aqueous lung fluid (if
data is available) and
路 have a low toxicity (i.e.. are not cytotoxic, genotoxic, or otherwise chemically
reactive with lung tissue, and do not emit ionizing radiation, cause immune sensitization
, or cause toxic effects other than by inflammation or by a mechanism of lung overload).
PERSONAL PROTECTION
EYE
路 Safety glasses with side shields.
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
NIOSH Current Intelligence Bulletin 59].
HANDS/FEET
No special equipment needed when handling small quantities.
OTHERWISE: Wear general protective gloves, eg. light weight rubber gloves. Or as required
: Wear chemical protective gloves, eg. PVC. Wear safety footwear.
OTHER

Section 11 - TOXICOLOGICAL INFORMATION
POTENTIAL HEALTH EFFECTS
ACUTE HEALTH EFFECTS
SWALLOWED
The material is. regarded as practically non-harmful if swallowed.
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.

Section 11 - TOXICOLOGICAL INFORMATION
EYE
Particulate/dust is. slightly discomforting to the eyes.
Alkaline salts may be intensely irritating to the eyes and precautions should be taken to
ensure direct eye contact is avoided.
SKIN
The material may be. discomforting to the skin from repeated exposures over long periods.
INHALED
Particulate/dust is. slightly 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 usually by skin contact/eye contact and inhalation of
generated dust.
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.
TOXICITY AND IRRITATION
unless otherwise specified data extracted from RTECS - Register of Toxic Effects of Chemical Substances.
No data of toxicological significance identified in literature search.
Section 12 - ECOLOGICAL INFORMATION
No data for potassium bicarbonate.
Section 13 - DISPOSAL CONSIDERATIONS
路 Recycle wherever possible or consult manufacturer for recycling options.
路 Consult State Land Waste Management Authority for disposal.
路 Bury residue in an authorised landfill.
