Mark “--” represents “Outside of regulation”.
Mark “L” represents “Substance regulated by the Industrial Safety andHealth Law”.
Mark “P” represents “Substance regulated by the PRTR Law”.

Concentration of each ingredient varies within the respective ranges given in
the table with the applicable standard and product grade. In addition to thegiven major ingredients, the products may contain trace amounts of carbon[C], silicon [Si], phosphorous [P], sulfur [S], copper [Cu] and vanadium [V],titanium[Ti], calcium[Ca], niobium[Nb], boron[B],and lead[Pb].
3. Hazards and Toxicity
Information[Most significant hazard and toxicity]
Under normal environments, there is no significant information on danger ortoxicity.
[Specific hazard and toxicity]
However, fumes generated during welding and fusing and fine particles
generated during grinding may irritate respiratory organs and mucosae of eyes
and other parts of a human body.

4. First Aid Measures

After having first aid, the patient shall see medical doctor if necessary.
Examples of first aid measures are given below.
- In case a person develops difficulty in breathing after inhalation of fumes
or other hazardous substances, use respiration support, and promptly callfor medical aid.
- In case a person is burned during or after welding or fusing work, cool theaffected part and call for medical aid if needed.
- In case fumes, fine particles, or foreign matter enters the eyes, wash the eyeswith water, and promptly call for medical aid.
- In case the skin is damaged by sharp edge, shavings, or other sharp debris of
the product, keep the wound clean, and call for medical aid if needed.

5. Fire FightingMeasures

The products are inflammable under normal environments. Fine powder ofthe products, however, may lead to abrupt combustion with oxygen. In such acase, a chemical fire extinguisher must be used.

6. Accidental Release
Measures

The products are in the solid phase under normal environments, and are notreleased.

7. Precautions on
Handling and Storage

8. Exposure Control andPersonal Protection[Handling]- [Technological measures]: Under normal environments, the products are
not hazardous, so they are not subject to technical measures on handlingand storage.
- [Precautions]: During works such as welding, fusing, grinding, andmachining, care should be taken to avoid inhalation of fumes and otherhazardous substances, to avoid suffering irritation of mucosae, and to avoid
injury by arcing, shavings, and other sharp debris. If necessary, localventilation, total ventilation, dust-preventive and dust-collective measures,
heat-shielding, fire proof measures, and other effective preventive
measures shall be taken.
- [Precautions for safe handling]: Since the products are heavy, care should
be taken to prevent falling down, rolling, collapse of a stack, and droppingof products. Sharp edges, shavings, and sharp debris of products may
damage the skin. For banded products, care should be taken during cutting
the bundle hoops/wires because the cut edges of the hoops/wires may
spring up.
[Storage]- [Technological measures]: Under normal environment, the product are nothazardous and toxic, so the storage of product does not need any
application of technological measures.
- [Chemical substances that shall not be mixed with] and [Storageconditions]: Avoid exposing the products to water, acid, and hightemperature and humidity.
- [Packaging materials for container]: Under normal environment, theproducts are not hazardous or toxic, so they are normally bare bundles.
At present, under environment of general use, no significant information isavailable relating to exposure control and personal protection measures.
[Protective gears]: For the works such as welding, fusing, grinding, andmachining, adequate protective gear is needed, such as mask, goggles, gloves,and clothes to prevent inhalation of fumes and other hazardous substances, toprevent irritation of mucosae, and to protect contact with arcing sparks andshavings. It is preferable to wear a helmet and safety-shoes to reduce theshock of collision with a heavy product.

9. Physical andChemical Properties[Physical properties]: Under normal environments, the products are solid in abar or shape.
[Physical properties]: Melting point: 1,400°C or above
Density: 7.85 g/cm3

10. Stability andReactivity[Stability]
Under normal environments, the products are stable.
[Reactivity]
On contact with water or an oxidizing substance, the products may initiate anoxidation reaction, leading to lack of oxygen or generating hydrogen.

11. Toxicological
Information

As steels, there is no significant epidemiological information such as “acutetoxicity” and “local effect”, at present.

12. Information on
Environmental Influences

At present, there is no significant information on environmental influences.

13. Precautions on
Disposal

In principle, disposal of the products shall be done by an authorized waste
treatment contractor with legal licenses.

3/4

If some part of the products attaches to the packaging material, the packaging
material shall also be treated as the product category.
14. Precautions onTransportation[Information relating to international regulations]
There is no law or regulation on transportation that specifies the iron and steel
products as dangerous chemical substances. Nevertheless, care shall be taken
to avoid collapse of a stack because the products are heavy. Furthermore, theproducts should preferably be covered with sheeting to prevent wetting withrain or other water.

15. Applicable Laws
and Regulations
16. Other Information

The Industrial Safety and Health Law[Reference Literature]- “Reasons for Recommendation of Allowable Concentrations” (edited bythe Japan Society for Occupational Health)- “International Chemical Safety Cards: Japanese Edition” (supervised by theEnvironmental Health Bureau of the Ministry of Health and Welfare)
The Safety Data Sheet (SDS) was prepared on the basis of materials andinformation available at present. This SDS is intended only as reference toassure safe handling of the products, and does not guarantee the safety of theproducts. Hazardous situations that are not described in the SDS and that are
not identified by JFE Bars & Shapes Corporation may exist. Therefore,
individuals that receive the SDS information must exercise their own
judgment in determining the appropriateness for a particular purpose with
their own responsibility and after sufficient education and adequate measures,
while referring to the SDS.
