4. First-aid measures

4.1. Description of first aid measures

There are no specific first aid measures developed for titanium and titanium alloys in massive form. Medical attention should be sought in case of an excessive inhalation of dust, a physical injury to the skin or to the eyes.

4.2. Most important symptoms and effects both acute and delayed

No relevant information has been identified.

4.3. Indication of any immediate medical attention and special treatment needed

No relevant information has been identified.

5. Firefighting measures

5.1. Extinguishing media

Titanium and titanium alloy in massive form are not combustible but material in the form of small chips, fine turnings or dust can self-ignite in moist air.

If possible; allow fire to burn out. Fire can be controlled by covering with powder from type D fire extinguisher, sand, or dry table salt. Carbon dioxide is not effective. Water applied to burning titanium may cause an explosion.

5.2. Special hazards arising from the mixture

Care should be taken to avoid exposing small chips, fine turnings and process dust (e.g. from grinding and blasting operations) to air and fire (auto-ignition temperature 250°C/480°F for powders).

5.3. Advice for firefighters

Dry titanium burns slowly while releasing much heat. Piled chips may burn vigorously.

6. Accidental release measures

6.1. Personal precautions, protective equipment and emergency procedures

Not applicable for the product in massive form.

For fines and dust; wear appropriate respiratory and protective equipment specified in section 8. Isolate spill area and provide ventilation. Avoid breathing dust or fume. Avoid contact with skin and eyes.

6.2. Environmental precautions

Not applicable for the product in massive form.

For fines and dust; do not allow to be released to the environment.

6.3. Methods and material for containment and cleaning up

Not applicable for the product in massive form.

For fines and dust; clean spills in a manner that not disperse dust into the air. Sweep or scoop up. Place in an appropriate container for further handling and disposal.

6.4 Reference to other sections

None.

7. Handling and storage

7.1. Precautions for safe handling

There are no special technical measures involved for handling titanium and titanium alloy in massive form. Normal precautions should be taken to avoid physical injury from coiled or bundled products, possibly with sharp edges.

Machining operations require the use of cutting fluids to reduce the temperature of waste material which might ignite without coolant.

7.2. Conditions for safe storage, including any incompatibilities

The product is stable in storage. However, it should be kept in mind that the products may display sharp edges and a sufficiently robust place capable of carrying the significant weight of the products should be used for storage.

7.3. Specific end uses

None identified.

8. Exposure controls/personal protection

8.1. Control parameters

Elements RD
Iron oxide as Fe 3.5
Aluminium as Al 2

Table 2 Occupational Exposure Limits, NGV, (mg/m3 ) in Sweden.
NGV = Nivågränsvärde (One working day exposure)
RD = Respirable dust

8.2. Exposure controls

8.2.1. Appropriate engineering controls

In the processing of all metallic materials, exposure to fume and dust must be kept below any legally imposed limits.

Dust and fume may be generated in use, e.g. by cutting, grinding and welding processes, which may contain materials subject to exposure limits. To ensure these limits are not exceeded, adequate general or local ventilation or fume extraction should be provided.

8.2.2. Individual protection measures, such as personal protective equipment

In accordance with European and national health and safety regulations, it is necessary to assess the need for personal protection equipment and appropriate approved respiratory protection should be provided for those workers at risk of inhalation. Suitable hand and eye protection should be worn where there is a risk of laceration, flying particles, welding heat radiation or contact with oils during processing.

The process of welding should only be performed by trained workers with the personal protective equipment in accordance with the laws of each member state relating to safety.

8.2.3. Environmental exposure controls

Emissions from ventilation or equipment in the workplace should be controlled to assure that environmental legislation is fulfilled.

13. Disposal considerations

13.1 Waste treatment methods

Surplus and scrap (waste) titanium and titanium alloy is a valuable commodity and in demand to produce prime titanium alloys. Recycling routes are well-established, and recycling is, therefore, the preferred disposal route. Disposal to landfill is not harmful to the environment but is a waste of resources and therefore less desirable than recycling. Due to the fire hazards of fines and dust, these shall be properly collected and placed in an appropriate container for further handling and disposal.
