HEALTH HAZARD
ACUTE HEALTH EFFECTS
SWALLOWED
Considered an unlikely route of entry in commercial/industrial environments The material is extremely
discomforting and corrosive if swallowed and is capable of causing burns to mouth, throat, oesophagus, with
extreme discomfort, pain. Ingestion may result in nausea, abdominal irritation, pain and vomiting. Other
acute toxic effects are salivation, lachrymation, dyspnea, weakness, lethargy, diarrhoea and coma. Single
and repeated dose studies in animals by oral and skin routes of cyanuric acid and some cyanurates
generally show a low degree of toxicity. Biochemical and haematological changes were not found in any
studies although at high doses several studies showed kidney damage (dystrophic changes, dilation of distal
collecting tubules and Bellini's duct, fibrosis and focal areas of epithelial proliferation). Short-term
administration of derivatives of s-triazines cause structural damage to the liver of test animals. The
significance of these results (if any) for human exposure cannot, as yet, be determined. [Foltinova etal - Folia
Histochemica 1971]. The s-triazines appear to act at the level of carbohydrate metabolism. The chlorinated,
methoxy and methylthio derivatives inhibit starch accumulation by blocking sugar production. The s-triazines
also cause the disappearance of sucrose and glyceric acid with the formation of aspartic and malic acids.
EYE
The dust may be highly discomforting and corrosive to the eyes, may cause burns and is capable of causing
severe damage with loss of sight. The material may produce moderate eye irritation leading to inflammation.
Repeated or prolonged exposure to irritants may produce conjunctivitis.
SKIN
The material is highly discomforting to the skin if contact is prolonged. Solution of material in moisture on the
skin, or perspiration, may increase irritant effects and is capable of causing burns. The material may produce
severe skin irritation after prolonged or repeated exposure, and may produce a contact dermatitis
(nonallergic). This form of dermatitis is often characterised by skin redness (erythema) and swelling
(oedema) which may progress to vesiculation, scaling and thickening of the epidermis. Histologically there
may be intercellular oedema of the spongy layer (spongiosis) and intracellular oedema of the epidermis.
Page 2 of 7
Prolonged contact is unlikely, given the severity of response, but repeated exposures may produce severe
ulceration.
INHALED
The dust may be extremely discomforting / corrosive if inhaled. The vapour from material which is wet is
highly discomforting and may be toxic if inhaled and if exposure is prolonged.
CHRONIC HEALTH EFFECTS
Principal routes of exposure are usually by inhalation of generated dust, skin contact with the dry and wet
material and inhalation of vapour given off by material that has become wet or damp. Ingestion will give rise
to corrosive attack on the mouth, oesophagus and internal organs and may result in weakness, lethargy,
tremors, salivation, lachrymation and possibly coma. Chlorine evolved from decomposition when wet is a
severe respiratory irritant, corrosive and highly toxic. Delayed effects can include shortness of breath, violent
headaches, pulmonary oedema and pneumonia. Experimental studies on laboratory animals indicate
possible teratogenic and other reproductive effects. [BASF]
FIRST AID
SWALLOWED
Rinse mouth out with plenty of water.
If poisoning occurs, contact a doctor or Poisons Information Centre.
In Australia phone 13 1126; New Zealand 03 4747000.
If swallowed, do NOT induce vomiting. Give a glass of water.
If vomiting occurs, give more water.
EYE
If this product comes in contact with the eyes:
1: Immediately hold the eyes open and wash continuously for at least 15 minutes with fresh running water.
2: 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.
3: Transport to hospital or doctor without delay.
4: Removal of contact lenses after an eye injury should only be undertaken by skilled personnel.
SKIN
Brush off dust. If product comes in contact with the skin:
1: Immediately remove all contaminated clothing, including footwear (after rinsing with water).
2: Wash affected areas thoroughly with water (and soap if available).
3: Seek medical attention in event of irritation.
INHALED
1: If dust is inhaled, remove to fresh air.
2: Encourage patient to blow nose to ensure clear breathing passages.
3: Ask patient to rinse mouth with water but to not drink water.
4: Seek immediate medical attention. or
1: If fumes or combustion products are inhaled: Remove to fresh air.
2: Lay patient down. Keep warm and rested.
3: If breathing is shallow or has stopped, ensure clear airway and apply resuscitation, preferably with a
demand valve resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary.
4: Transport to hospital, or doctor.
ADVISE TO THE DOCTOR
Treat symptomatically.
Effects from exposure to chlorine gas include pulmonary oedema, which may be delayed. Observation in
hospital for 48 hours is recommended.

PRECAUTIONS FOR USE
EXPOSURE STANDARDS
REL: 0.5 mg/m3; STEL: 1.5 mg/m3 [Manfr.]
Evolves chlorine in presence of moisture/water.
chlorine:
TLV TWA: 0.5 ppm, 1.5 mg/m3; STEL: 1 ppm, 2.9 mg/m3
ES Peak: 1 ppm, 3 mg/m3 :
ODOUR SAFETY FACTOR (OSF)
OSF=1.6
Exposed individuals are NOT reasonably expected to be warned, by smell, that the Exposure Standard is
being exceeded. Odour Safety Factor (OSF) is determined to fall into either Class C, D or E. The Odour
Safety Factor (OSF) is defined as: OSF= Exposure Standard (TWA) ppm/ Odour Threshold Value (OTV)
ppm Classification into classes follows:
Class OSF Description
------------------------------------------------------------------------------------------------------------------------------------------------
A 550 Over 90% of exposed individuals are aware by smell that the Exposure Standard
(TLV-TWA for example) is being reached, even when distracted by working activities
B 26-550 Idem for 50-90% of persons being distracted
C 1-26 Idem for less than 50% of persons being distracted
D 0.18-1 10-50% of persons aware of being tested perceive by smell that the Exposure
Standard is being reached
E <0.18 Idem for less than 10% of persons aware of being tested
------------------------------------------------------------------------------------------------------------------------------------------------
Amoore and Hautala * have determined that it is only at an OSF value of 26 that 50% of distracted persons
can detect the substance at the Exposure Standard value. In the case of alerted persons, an OSF of 26
means that 99% of them can detect the odour at the Exposure Standard value. It is ONLY for substances
belonging to Class A and B that there is a reasonable chance of being warned in time, that the Exposure
Standard is being exceeded.
* Journal Applied Toxicology: Vol 3, 1983, p272
NOTE: The use of the OSF may be inappropriate for mixtures where substances mask the odour of others.
ENGINEERING CONTROLS
Use in a well-ventilated area General exhaust is adequate under normal operating conditions. Local exhaust
ventilation may be required in special circumstances. If risk of overexposure exists, wear approved respirator
Supplied-air type respirator may be required in special circumstances. Correct fit is essential to ensure
adequate protection. Provide adequate ventilation in warehouses and enclosed storage areas.
PERSONAL PROTECTION
EYES
Safety glasses with side shields Chemical goggles.
Contact lenses pose a special hazard; soft lenses may absorb irritants and all lenses concentrate them.
HANDS / FEET
Wear chemical protective gloves, eg. PVC. Wear safety footwear.
DO NOT handle directly. Wear gloves and use scoop / tongs / tools.
Neoprene gloves.
Nitrile rubber gloves.
OTHER
1: Overalls.
2: PVC Apron.
3: PVC protective suit may be required if exposure severe.
4: Eyewash unit.
5: Ensure there is ready access to a safety shower.
