HEALTH EFFECTS

ACUTE EFFECTS

SWALLOWED: Product is highly alkaline and may cause severe damage to digestive tract. May cause burns and irritate mucous membrane.

EYE: Irritant to eyes. May cause eye burns and corneal damage.

SKIN: Dust is irritant to skin due to high alkalinity. Can cause skin sensitisation.

INHALED: Dust is irritating to the respiratory tract. May cause coughing, wheezing, shortness of breath and pulmonary edema.

CHRONIC EFFECTS

Repeated or prolonged contact especially under wet conditions may cause eye and skin inflammation.

FIRST AID

SWALLOWED: IF conscious, immediately rinse mouth with water & give water to drink. Do not induce vomiting. Seek immediate medical assistance.

EYE: Immediately irrigate with copious quantities of water for at least 15 minutes. Eyelids to be held open. Seek immediate medical assistance.

SKIN: Remove contaminated clothing. Wash affected area with large amounts of soap and water. Seek medical assistance if irritation persists.

INHALED: Remove victim from exposure - avoid becoming a casualty. Remove contaminated clothing and loosen remaining clothing. Allow patient to assume most comfortable position and keep warm. Keep at rest until fully recovered. If breathing laboured ensure airways are clear and administer oxygen. If breathing has stopped apply artificial respiration at once. Seek immediate medical assistance.

ADVICE TO DOCTOR

Treat symptomatically.

EXPOSURE STANDARDS

No value assigned by Worksafe Australia.

Due to irritant effects on mucous membranes the following dust exposure limit should be enforced:

TWA: <10mg/m3

TWA is the Time-Weighted Average airborne concentration over an 8-hour working day, for a 5-day working week over an entire working life.

ENGINEERING CONTROLS

Provide general and/or local exhaust ventilation system. Maintain exposures below the recommended exposure standard.

PERSONAL PROTECTION

Avoid skin and eye contact and inhalation of dust. Wear overalls, safety glasses or goggles and chemical resistant gloves and boots. Respiratory protection is required if airborne concentration exceeds exposure standards. Use an approved dust particle mask. Always wash hands before smoking, eating, drinking or using the toilet.

FLAMMABILITY

Not flammable.

STORAGE AND TRANSPORT

Not classified as a dangerous Good by the Australian Code for the Transport of Dangerous Goods by Road and Rail. Store in a cool, dry, well ventilated place. Keep containers tightly sealed to prevent contact with moisture, which will cause the product to cake. Keep away from incompatible materials and foodstuffs. Protect from physical damage.

SPILLS

Wear proper protective equipment. Sweep up but avoid generating dust. Avoid contact with acids. Transfer spilled material into clean-labelled sealable containers for disposal.

Prevent from entering drains, sewers, streams or other bodies of water. If contamination of sewers or waterways has occurred, advise the local emergency services.

DISPOSAL

Refer to federal, state or local regulations.

FIRE/EXPLOSION HAZARDS

Non combustible material.

Extinguishing media is governed by other materials present. In the event of a fire, the material will generate toxic and irritating fumes. For this reason fire fighters to wear self contained breathing apparatus and full protective clothing when fighting fire.

TOXICITY

ACUTE TOXICITY:

ORAL LD50 (rat): 7400 mg/kg

ENVIRONMENTAL IMPACT

No specific data available but high concentrations in receiving waters will harm aquatic life by raising pH. The orthophosphate can act as a plant nutrient and precipitate heavy metals.
