Dihydrogen hexafluorotitanate(2-)

Guidance on Safe Use

First-aid measures

- General advice:

First aider needs to protect himself. Medical assistance essential. Remove all contaminated clothing while washing continuously. After thorough washing the burned area should be immersed in a solution of 0.1% iced aqueous Benzalkonium Chloride. As an alternate first aid treatment, 2.5% calcium gluconate gel may be continuously massaged into the burn area. Further treatment by physician.

- Inhalation:

Remove to fresh air. Keep patient warm and at rest. Get competent medical attention immediately. If breathing has stopped, start artificial respiration at once. An authorized person should administer oxygen to a victim who is having difficulty breathing, until the victim is able to breathe easily by himself. Calcium Gluconate, 2.5% in normal saline may be given by nebulizer with oxygen. Do not give stimulants unless instructed to do so by a physician. Victim should be examined by a physician and held under observation for at least 24 hours.

- Skin contact:

Limit washing to 5 minutes if treatment specific for HF exposure is available. Remove all contaminated clothing while washing continuously. After thorough washing for at least 5 minutes, the burned area should be immersed in a solution of 0.13% iced aqueous Benzalkonium Chloride until pain is relieved. As an alternate first aid treatment, 2.5% calcium gluconate gel may be continuously massaged into the burn area until the pain is relieved. For larger burns or burns treated with calcium gluconate gel (in which pain is present longer than 30 minutes), a physician should inject 5% aqueous calcium gluconate beneath, around and in the burned area. Use of local anesthetics is not recommended, as reduction in pain is an indicator of effectiveness of treatment.

- Eye contact:

Irrigate eyes for at least 15 minutes with copious quantities of water, keeping eyelids apart and away from eyeballs during irrigation. Get competent medical attention immediately, preferably an eye specialist. If a physician is not immediately available, apply one or two drops of 0.5% tetracaine hydrochloride solution, or other aqueous, topical ophthalmic anesthetic and continue irrigation. Do not use the solution described for skin treatment (Benzalkonium Chloride). Use no other medications unless instructed to do so by a physician. Rubbing of the eyes is to be avoided. Irrigate with 1% calcium gluconate in normal saline for 1 to 2 hours to prevent or lessen corneal damage.

- Ingestion:

Call a physician immediately. Drink plenty of water. Do NOT induce vomiting. Magnesium hydroxide (milk of Magnesia) as an antacid may be given.

- Notes to physician

Treatment : For large skin area burns (totaling greater than 25 square inches), for ingestion and for significant inhalation exposure, severe systemic effects may occur. Monitor and correct for hypocalcemia, cardiac arrhythmias, hypomagnesemia and hyperkalemia. In some cases hemodialysis may be indicated.

For certain burns, especially of the digits, use of intra-arterial calcium gluconate may be indicated. For inhalation exposures, treat as chemical pneumonia. Monitor for hypocalcemia. 2.5% calcium gluconate in normal saline by nebulizer or by intermittent positive pressure breathing with 100% oxygen may decrease pulmonary damage. Bronchodilators may also be administered.

Fire-fighting measures

- Suitable extinguishing media:

Water spray, Foam, Carbon dioxide (CO2), Dry powder

- Special protective equipment for fire-fighters:

In the event of fire, wear self-contained breathing apparatus.

-Further information:

Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.

Accidental release measures

- Personal precautions:

Ensure adequate ventilation. Use personal protective equipment. Evacuate personnel to safe areas.

- Methods for cleaning up:

Neutralise with the following product(s): lime

Handling and storage

Exposure controls / personal protection

- Occupational exposure limits:

IOELV: 2.5 mg/m³ based on fluoride

Adopted as a DNEL under REACH. Corresponds to 3.6 mg H2TiF6/m³.              

Personal protective equipment

- Respiratory protection : Full mask,

- Hand protection: Glove material: Viton (R), Break through time: > 480 min, Glove thickness: 0,7 mm, Vitoject 890

Remarks: Supplementary note: The specifications are based on information and tests from similar substances by analogy. Due to varying conditions ( e.g.temperature or other strains) it must be considered that the usage of a chemical protective glove in practice may be much shorter than the permeation time determined in accordance with EN 374. Since actual conditions of practical use often deviate from standardised conditions according EN 374 the glove manufacturer reccomends to use the chemical protective glove in practice not longer than 50% of the recomended permeation time.

Manufacturer´s directions for use should be observed because of great diversity of types. Suitable gloves tested according EN 374 are supplied e.g. from KCL GmbH, D-36124 Eichenzell, [e-mail].

- Eye protection : see respiratory protection

- Skin and body protection : acid-proof protective clothing

- Protective measures : The Personal Protective Equipment must be in accordance with EN standards:respirator EN 136, 140, 149; safety glasses EN 166; protective suit: EN 340, 463, 468, 943-1, 943-2; gloves EN 374, safety shoes EN-ISO 20345. Keep working clothes separately. Take off all contaminated clothing immediately. Avoid contact with skin and eyes.
