Tetrasodium (1-hydroxyethylidene)bisphosphonate

Guidance on Safe Use

First-aid measures

Inhalation : Move the person away from the contaminated area.  Make the affected person rest.   If necessary seek medical advice.

Skin contact : Remove all contaminated clothing and footwear.  Wash with soap and water.  In case of inflammation (redness, irritation) obtain medical attention.

Eye contact : Immediately rinse with plenty of running water for a prolonged period (at least 15 minutes) whilst keeping the eyes wide open.  If irritation persists consult a doctor.

Ingestion : NEVER attempt to induce vomiting.  Rinse out mouth with water.  If necessary seek medical advice.

Further information : Place contaminated clothing in a sealed bag for disposal.  Use appropriate protective equipment when treating a contaminated person.

Fire-fighting measures

EXTINGUISHING MEDIA

Suitable : All extinguishing agents can be used (water, foam, powders, carbon dioxide, sand).

Not suitable : None to our knowledge.  If there is fire close by, use suitable extinguishing agents.

Specific hazards : On heating or during combustion corrosive vapours are released.  Dense white fumes are given off which may obscure the area.  Toxic and highly flammable gases are released which increase fire/explosion hazards.  

Specific fire fighting methods:  Usual methods for dealing with chemical fires.  Cool down the containers/equipment exposed to heat with a water spray.

Protection of fire-fighters : Self-contained breathing apparatus.  Complete protective clothing.

Accidental release measures

PERSONAL PRECAUTIONS

Avoid contact with eyes, skin and respiratory system.  

If spillage occurs on the public highway, indicate the danger and notify the authorities (police, fire brigade).  Wear full protective clothing and equipment.  

Environmental precautions : Contain the spilled material by bunding.  Avoid direct discharge into drains.

METHODS FOR CLEANING UP

Recover as much of the product as possible.  

Absorb the product onto porous material (liquid form).

Collect up the product and place it in a spare container, suitably labelled.  then take the emergency containers to an area reserved for subsequent recycling or disposal.

Neutralise with:

Calcium hydroxide; sodium bicarbonate (liquid form).

Absorb spillage with diatomaceous earth; sand or inert absorbent.

Cleaning/decontamination : Wash non-recoverable remainder with large amounts of water.

DISPOSAL

Do NOT discharge into drains.

Dispose of all contaminated materials in accordance with current regulations.

Place in an appropriate container and dispose of the contaminated material at a licensed site.

Handling and storage

HANDLING

Technical measures : Ventilation.  

Only use materials resistant to acids (liquid form).

Safe handling advice : Handle and use in accordance with good occupational hygiene and safety practice.

STORAGE

Technical measures : Take all necessary precautions to avoid the accidental release of the product outside, due to the nature of containers or transfer systems. Ensure that there is a suitable retention system.  Storage facilities should be dry.

STORAGE CONDITIONS

Recommended : Store in a cool dry area.

Incompatible products : Oxidising agents and oxidising materials.  

PACKAGING

Plastic materials (polyethylene, polypropylene) (high density (liquid and solid form).

Recommended : Original packaging.

Not suitable : Metals.

Very corrosive to metals (hydrogen is released which forms an explosive mixture in air (liquid form).
