PRODUCT USE
Used in cooling water treatments as deflocculant and sequestrant. Use in
photography. Phosphonates ligands demonstrate a very high affinity for alkali
metal ions. They form crystals with some difficulty and are usually distributed
commercially as 25 to 60% aqueous solutions of acids or sodium salts with
technical grade purity. Organophosphonate chelating compounds are widely used in
a broad variety of applications. Their ability to prevent precipitation of
calcium salts at stoichiometric concentrations finds wide application in water
treatment for scale inhibition and in corrosion inhibition. Other uses include
peroxy bleach stabilisation, span applications in flame-resistant polymers,
photographic processing, ore flotation (aminophosphonic surfactants), actinide
separation processes and analytical chemistry. The high biological activity of
carboxyalkylphosphonates, aminoalkylphosphonates, and alkylenediphosphonates,
make them useful as agents in microfertilisers and pesticides, in agriculture,
as well as drugs and diagnostic reagents in biology and medicine. Impurities
including H3PO4, H3PO3 and ligands of lower denticity, are quite common for
phosphonates.

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? Immediately hold eyelids apart and flush the eye continuously with 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? 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? Immediately flush body and clothes with large amounts of water, using safety
shower if available.
鈥? Quickly remove all contaminated clothing, including footwear.
鈥? Wash skin and hair with running water. Continue flushing with water until
advised to stop by the Poisons Information Centre.
鈥? Transport to hospital, or doctor.
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 short term repeated exposures to strong acids:
鈥? Airway problems may arise from laryngeal edema and inhalation exposure. Treat
with 100% oxygen initially.
鈥? Respiratory distress may require cricothyroidotomy if endotracheal intubation
is contraindicated by excessive swelling
鈥? Intravenous lines should be established immediately in all cases where there
is evidence of circulatory compromise.
鈥? Strong acids produce a coagulation necrosis characterised by formation of a
coagulum (eschar) as a result of the dessicating action of the acid on proteins
in specific tissues.
INGESTION:
鈥? Immediate dilution (milk or water) within 30 minutes post ingestion is
recommended.
鈥? DO NOT attempt to neutralise the acid since exothermic reaction may extend the
corrosive injury.
鈥? Be careful to avoid further vomit since re-exposure of the mucosa to the acid
is harmful. Limit fluids to one or two glasses in an adult.
鈥? Charcoal has no place in acid management.
鈥? Some authors suggest the use of lavage within 1 hour of ingestion.
SKIN:
鈥? Skin lesions require copious saline irrigation. Treat chemical burns as
thermal burns with non-adherent gauze and wrapping.
鈥? Deep second-degree burns may benefit from topical silver sulfadiazine.

FOOTNOTES
1 PROTECTIVE ACTION ZONE is defined as the area in which people are at risk
of harmful exposure. This zone assumes that random changes in wind direction
confines the vapour plume to an area within 30 degrees on either side of the
predominant wind direction, resulting in a crosswind protective action distance
equal to the downwind protective action distance.
2 PROTECTIVE ACTIONS should be initiated to the extent possible, beginning with
those closest to the spill and working away from the site in the downwind
direction. Within the protective action zone a level of vapour concentration
may exist resulting in nearly all unprotected persons becoming incapacitated
and unable to take protective action and/or incurring serious or irreversible
health effects.

Section 6 - ACCIDENTAL RELEASE MEASURES
3 INITIAL ISOLATION ZONE is determined as an area, including upwind of the
incident, within which a high probability of localised wind reversal may
expose nearly all persons without appropriate protection to life-threatening
concentrations of the material.
4 SMALL SPILLS involve a leaking package of 200 litres (55 US gallons) or less,
such as a drum (jerrican or box with inner containers). Larger packages leaking
less than 200 litres and compressed gas leaking from a small cylinder are also
considered "small spills".
LARGE SPILLS involve many small leaking packages or a leaking package of
greater than 200 litres, such as a cargo tank, portable tank or a "one-tonne"
compressed gas cylinder.
5 Guide 153 is taken from the US DOT emergency response guide book.

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
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].
HANDS/FEET

ENGINEERING CONTROLS
Use in a well-ventilated area.
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.

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.

The principal problems of phosphate contamination of the environment relates to
eutrophication processes in lakes and ponds. Phosphorus is an essential plant
nutrient and is usually the limiting nutrient for blue-green algae. A lake
undergoing eutrophication shows a rapid growth of algae in surface waters.
Planktonic algae cause turbidity and flotation films. Shore algae cause ugly
muddying, films and damage to reeds. Decay of these algae causes oxygen
depletion in the deep water and shallow water near the shore. The process is
self-perpetuating because anoxic conditions at the sediment/water interface
causes the release of more adsorbed phosphates from the sediment. The growth of
algae produces undesirable effects on the treatment of water for drinking
purposes, on fisheries, and on the use of lakes for recreational purposes.
