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:
路 the architecture of the air spaces remain intact,
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).
INGREDIENT DATA
AMMONIA:
Odour Threshold Value: Variously reported as 0.019 ppm and 55 ppm;
AIHA Value 16.7 ppm (detection)
NOTE: Detector tubes for ammonia, measuring in excess of 1 ppm, are
commercially available.
The TLV-TWA is thought to be protective against irritation of the eyes and
respiratory tract and minimise discomfort among workers that are not
inured to its effects and systemic damage. Acclimatised persons are able
to tolerate prolonged exposures of up to 100 ppm without symptoms. Marked
irritation has been seen in persons exposed to ammonia concentrations
between 50 and 100 ppm only when the exposures involved sudden

of the lips, restlessness, headache, salivation, nausea,
vomiting, glottal oedema, pharyngitis, tracheitis, and speech
difficulties. Bronchopneumonia, asphyxiation due to spasms,
inflammation, and oedema of the larynx, may be fatal. Residual
effects include hoarseness, productive cough, and decreased
respiratory function
>2500 severe eye irritation, with swelling of the eyelids,
lachrymation, blepharospasm, palpebral oedema, increased
intraocular pressure, oval semi-dilated, fixed pupils, corneal
ulceration (often severe) and temporary blindness. Depending on
duration of exposure, there may be destruction of the
epithelium, corneal and lenticular opacification, and iritis
accompanied by hypopyon or haemorrhage and possible loss of
pigment from the posterior layer of the iris. Less severe
damage is often resolved. In the case of severe damage,
symptoms may be delayed; late complications including
persistent oedema, vascularisation and corneal scarring,
permanent opacity, acute angle glaucoma, staphyloma, cataract,
and atrophy of the retina, iris, and symblepharon.
Long-term exposure to sub-acute concentrations or single exposures to
high concentrations may produce chronic airway dysfunction, alveolar
disease, bronchiolitis, bronchiectasis, emphysema and anxiety neuroses

ENGINEERING CONTROLS
General exhaust is adequate under normal operating conditions. Local exhaust ventilation
may be required in specific circumstances. If risk of overexposure exists, wear 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., evaporating 0.25- 0.5 m/s (50- 100 f/min)
from tank (in still air).
aerosols, fumes from pouring operations, 0.5- 1 m/s (100- 200 f/min.)
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 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.)

3: Intermittent, low production. 3: High production, heavy use
4: Large hood or large air mass in motion 4: Small hood- local control only
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.

Section 11 - TOXICOLOGICAL INFORMATION
POTENTIAL HEALTH EFFECTS
ACUTE HEALTH EFFECTS
SWALLOWED
The material is moderately discomforting to the gastro-intestinal tract and may be
harmful if swallowed.
As absorption of phosphates from the bowel is poor, poisoning this way is less likely.
Effects can include vomiting, tiredness, fever, diarrhoea, low blood pressure, slow pulse
, cyanosis, spasms of the wrist, coma and severe body spasms.
Large doses of ammonia or injected ammonium salts may produce diarrhoea and may be
sufficiently absorbed to produce increased production of urine and systemic poisoning.
Symptoms include weakening of facial muscle, tremor, anxiety, reduced muscle and limb
control.
EYE
The material is moderately discomforting to the eyes and is capable of causing a mild,
temporary redness of the conjunctiva (similar to wind-burn), temporary impairment of
vision and/ or other transient eye damage/ ulceration.
SKIN
The solid/dust is. 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.
INHALED
The dust is. mildly 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.
Sodium phosphate dibasic can cause stones in the kidney, loss of mineral from the bones
and loss of thyroid gland function.

The material may produce severe irritation to the eye causing pronounced inflammation.
Repeated or prolonged exposure to irritants may produce conjunctivitis.
Asthma-like symptoms may continue for months or even years after exposure to the material
ceases. This may be due to a non-allergenic condition known as reactive airways
dysfunction syndrome (RADS) which can occur following exposure to high levels of highly
irritating compound. Key criteria for the diagnosis of RADS include the absence of
preceding respiratory disease, in a non-atopic individual, with abrupt onset of
persistent asthma-like symptoms within minutes to hours of a documented exposure to the
irritant. A reversible airflow pattern, on spirometry, with the presence of moderate to
severe bronchial hyperreactivity on methacholine challenge testing and the lack of
minimal lymphocytic inflammation, without eosinophilia, have also been included in the
criteria for diagnosis of RADS. RADS (or asthma) following an irritating inhalation is an
infrequent disorder with rates related to the concentration of and duration of exposure
to the irritating substance. Industrial bronchitis, on the other hand, is a disorder that
occurs as result of exposure due to high concentrations of irritating substance (often
particulate in nature) and is completely reversible after exposure ceases. The disorder
is characterised by dyspnea, cough and mucus production.
Section 12 - ECOLOGICAL INFORMATION
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.
Refer to data for ingredients, which follows:
AMMONIA:
Fish LC50 (96hr.) (mg/l): 0.45- 0.8
In air ammonia is persistent whilst, in water, it biodegrades rapidly to nitrate,
producing a high oxygen demand. Ammonia is strongly adsorbed to soil. Ammonia is non
-persistent in water (half-life 2 days) and is moderately toxic to fish under normal
temperature and pH conditions. Ammonia is harmful to aquatic life at low concentrations
but does not concentrate in the food chain.
