Telephone Number: (+61) 8 9314 7595
Fax Number: (+61) 8 9314 7595
Emergency Telephone Numbers: (+61) 8 9433 5875; 0411 297 030 (mobile)
2. Composition/information on ingredients
To lower pH of hydroponic nutrient solutions.
Common Name CAS EINECS Conc
Orthophosphoric acid 7664 - 38 - 2 - 80% W/V
Water to 100%
3. Hazards identification
Swallowed: Causes burns to the mouth, throat and stomach. Can cause nausea, difficulty in breathing, shock, acidosis,
convulsions and collapse.
Eye: Causes irritation or burns. No permanent damage is expected if treated immediately.
Skin: Causes irritation or burns. Dermatitis may result from prolonged exposure. Injuries more severe with hot acid.
Inhaled: Cause irritation to the respiratory system. Vapours and mists are corrosive to the nose, throat and mucous membranes.
4. First-aid measures
Swallowed: DO NOT induce vomiting. If conscious give a little water to drink. Obtain medical attention immediately.
Eye: Irrigate eyes with gently flowing water for 15 minutes with eyelids held open. Take care not to rinse the contaminated
water into the non affected eye. If irritation persists repeat the flushing. Obtain medical attention immediately.
Skin: Flush with plenty of clean water for at least 15 minutes while removing contaminated clothing and footwear. Affected
clothing should be washed before reuse. Obtain medical attention immediately.
Inhaled: Remove victim from exposure - avoid becoming a casualty and remove contaminated clothing. If breathing is difficult
give oxygen. Obtain medical attention immediately.

5. Fire fighting measures
Fire / Explosion: Not combustible. Material is stable under normal conditions of use. Strong alkalis will liberate much heat and
cause spattering. Most metals will cause formation of flammables and explosive hydrogen gases. Sulphide, phosphide, cyanide,
carbides and silicides reactions release poisonous gases. Hazardous decomposition products include toxic gases and vapours
(phosphoric acid fumes may be released). May release phosphorous oxide.
Flammability: Not flammable.
Extinguishing Media: Use water spray, dry chemical, carbon dioxide or foam type extinguishers. Contact with most metals
produces hydrogen which may form flammable mixtures with air. Keep containers cool by spraying with water.
6. Accidental release measures
Spills: Clear area of all unprotected / unnecessary people. Wear full protective equipment to prevent skin and eye contact.
Contain using sand and/or earth. Prevent runoff into drains or waterways. Can be greatly diluted or carefully neutralized with soda
ash, lime, calcium carbonate and flushed to drain with copious amounts of water. Use absorbent (soil or sand, sawdust, inert
material, vermiculite). Collect and hold in suitable containers for waste disposal. Wash spill area down with large amounts of water.
Disposal (After treatment above)
Refer to waste management authority. Empty containers MUST BE decontaminated.
7. Handling and storage
Avoid breathing mist. Prevent contact with eyes, skin or clothing. Keep container tightly closed. Keep away from direct sunlight,
alkalis, sulphides, cyanides and metal powders. Check regularly for leaks.
8. Exposure controls/personal protection
Generally not a hazard when handled carefully and as instructed. However, as a precaution, especially if splashing of liquid is
possible, suitable (approved) personal protective equipment appropriate to the task should be worn:
Hand: Use gloves resistant to acids (rubber).
Eyes: Approved chemical safety goggles or face protection. Contact lenses pose a hazard: Soft lenses may absorb irritants, and all
contact lenses concentrate irritants. Particles may adhere to contact lenses and cause corneal damage.
Skin: Wear protective overalls buttoned at the wrist and neck (or bib resistant to acids) and impervious footwear (rubber boots).
Sleeves of jackets or shirts should be buttoned over the glove wrists; trousers should be worn with the bottoms of legs outside the
boots - not tucked in.
Respiration: Use an approved respirator - Seek professional advice.
Note, eye wash fountains and safety showers should be located near any area where large quantities of this product are handled.
Remove contaminated clothing promptly. Keep contaminated clothing in closed containers. Discard or launder before re-wearing.
Inform laundry personnel of contaminants hazards. Do not smoke, eat or drink in work areas. Wash hands thoroughly after handling
this material. Maintain good housekeeping.
Engineering controls:
Ensure adequate ventilation and / or local exhaust ventilation where misting can occur to maintain exposure levels below standard.
9. Physical and chemical properties
Appearance: Clear, colourless, odourless, aqueous solution.
Boiling Point / Melting Point: Stable below 55oC. Above 55oC the decomposition rate depends on temperature.
Vapour Pressure: Not applicable
Specific Gravity: 1.39
Flashpoint: Not flammable
Flammability Limits: Not flammable
Solubility in Water: Soluble in all proportions
pH: acidic (pH 1.5 for 2% solution)
Corrosiveness: Attacks most metals.
10. Stability and reactivity
Stable under normal conditions. Reacts vigorously and exothermically on mixing with alkalis. No exotherm on dilution with water.

11. Toxicological information
Toxicity Data:
Treat symptomatically based on judgment of doctor and individual reactions of patient.
Oral LD5O = 1530 mg/kg (Rat)
Dermal LD5O: 2740 mg/kg (rabbit)
Inhalation TCLo: = 100mg/M3 (human)
Exposure standards: Worksafe Australia recommends TWA 1mg/m3 STEL 3mg/m3.
For further information: See Section 3 of this MSDS ("Hazards Identification").
12. Ecological information
Prevent product from entering rivers, canals and other waterways: Acidic, nutrient for undesirable algae. While acidity may be
reduced by natural water hardness minerals, the phosphate may persist indefinitely.
