No signal word or hazard statement.
There are no hazards of concern for man or the environment from Zr 702 in the forms supplied.

There are no specific first aid measures developed for zirconium and zirconium 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.
No relevant information has been identified.
No relevant information has been identified.
Zirconium and zirconium alloys in massive form are not combustible but material in the form of small chips, fine turnings or dust can self-ignite at room temperature or if exposed to any nearby heat source.
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 zirconium may cause an even bigger fire or an explosion.
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 330 °C/626 °F for powders). Emits toxic fumes under fire conditions.
Dry zirconium and zirconium alloy powder burns while releasing much heat. Piled chips burn vigorously.
If a fire starts in a mass of wet metal fines, such as a drum of damp machining chips, the initial fire may be followed by an explosion. Therefore, when in doubt, individuals should leave and not attempt to extinguish the fire, but let it burn out. The explosion characteristics of such material are caused by the hydrogen and steam generated by the burning mass.
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 fumes. Avoid contact with skin and eyes.
Not applicable for the product in massive form.
For fines and dust; do not allow to be released to the environment.
Not applicable for the product in massive form.
For fines and dust; clean spills in a manner not to disperse dust into the air. Sweep or scoop up. Do not use metallic tools or equipment due to the risk of sparking.
Place in an appropriate container for further handling and disposal according to local rules.
None.
There are no special technical measures involved for handling zirconium and zirconium alloys 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.
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.
Keep fine turnings completely dry or very wet. When wet, the water content should be more than 25 percent by weight for maximum safety in handling. Severe explosions can result from the ignition of Zirconium powder or machining fines containing moisture in the concentration range of 5-10 percent.
None identified.

Table 2 Occupational Exposure Limits, NGV, (mg/m3 ) in Sweden.
NGV = Nivågränsvärde (One working day exposure)
TD = Total dust
ID = Inhalable dust
RD = Respirable dust
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.
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.
Emissions from ventilation or equipment in the workplace should be controlled to assure that environmental legislation is fulfilled.

Zirconium has no specified effect for dermal, inhalation or oral exposure.
During mechanical working, flame-cutting, or welding, dust, or fumes may be formed. Over long periods, inhalation of excessive airborne levels may have long term health effects, primarily affecting the lungs.
Zirconium is not classified as carcinogenic.
Zirconium is not classified as mutagenic.
Zirconium is not toxic for reproduction.

Do not allow material to be released to the environment without proper governmental permits. No further relevant information available.
Surplus and scrap (waste) of zirconium and zirconium alloys is a valuable commodity and in demand to produce prime zirconium 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; accidental fires should be controlled by covering with a dry powder type of extinguisher.
For Zirconium scrap (turnings), UN number 1932 is valid for land, railway, inland waterway, marine and air transport. Corresponding packaging class is IMO 4.2.
No chemical safety assessment has been published.
