Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

First-aid measures


Breathe fresh air. If breathing discomfort occurs and persists after cessation of exposure, see a medical doctor.

Skin contact:

Rinse with water and soap.

Take off immediately all contaminated clothing.

Consult a doctor if irritation persists.

Eye contact:

In case of contact with eyes, flush with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers.

Seek medical advice.


If swallowed, rinse mouth with water (only if the person is conscious).

Do not induce vomiting.

Seek medical advice at once.

Fire-fighting measures

Suitable extinguishing media:

Put out the fire using appropriate agents against the surrounding fire.

Extinguishing media which must not be used for safety reasons:


Special exposure hazards arising from the substance orpreparation itself , combustion products, resulting gases:


Hydrogen gas is released in contact with most metals.

Special protective equipment for fire-fighters:

According to the combustible substance involved.

Other recommendations:

Cool closed containers exposed to fire with water spray.

Accidental release measures

Personal precautions:

Wear personal protective equipment.

Environmental precautions:

Contain and collect spillage with non,combustible absorbent material, (e.g. sand, earth, diatomaceus earth, vermiculite).

Avoid undiluted spillage entering the sewers, basements or pits and watercourses.

Methods for cleaning up:

Ventilate area and wash spill site after material pickup is complete.

Throw sand, ashes or powder cement to absorb the liquid.

Neutralise with slaked lime (calcium hydroxide), sodium carbonate, calcium carbonate or sodium bicarbonate.

Place in container for disposal according to local / national regulations.

Handling and storage


Store in cool, dry, clean, well,ventilate areas away from alkalini products and metals.

Do not store under direct sun light.

Do not pile up the containers.

Do not store at temperatures close to freezing point.

Compatible materials:

Stainless steel 316-L.

High-density polyethylene.

Exposure controls / personal protection

Exposure limits:

8-hour TWA (ACGIH -US / EU): 1 mg/m3

15-min STEL (EU ELV): 2 mg/m3

Respiratory protection:

Not required to usual works.

In foggy/vapours situations, use a spreading over all facemask with a suitable inorganic acid filter.

If product air concentration is not known, use autonomous breathing equipment.

Hand protection:

Wear suitable gloves (Neoprene gloves)

Eye Protection:

Chemical safety goggles to chemical products or a face protection shield.

Skin protection:

Use natural rubber boots.

Use acid resistant protective clothing.

Stability and reactivity


Stable in recommanded storage conditions.


Exothermic reaction with water.

Reacts violently with strong alkalis.

In contact with reactive metals (as steel to carbon & aluminum) may produce hydrogen.

At high temperature formation of phosphorous oxides.

Disposal considerations

The neutralised liquid can be spilled in accordance to reglamentary normative (Law regulates emptying wastewater containing phosphorous).

The residue of the containers or the used container itself should be disposed in accordance with local requirements.

Sodium carbonate, calcium carbonate and slaked lime (calcium hydroxide) can be used as neutralisers' agents for the material

that cannot be eliminated.

If phosphoric acid is going to be used in aqueous solutions reactions, rinse three times the drum with water.

Comply with local regulations for disposal.
