4. FIRST AID MEASURES
If dust or fumes emitted during the processing, etc., of steel materials are inhaled oringested, or skin contact, carry out the following first aid measures. If necessary, obtain
medical advice or attention from a physician.
・Inhaled: Remove person to fresh air and keep comfortable for breathing.
・Skin contact: Wash with soap and plenty of water immediately.

・Eye contact: Rinse cautiously with water for several minutes. Remove contactlenses, if it can be easily removed,and continue to wash.

・Ingestion: Rinse mouth thoroughly and immediately with water.

・Other: Maintain the cleanliness of the would if injuring the skin with a steel
cutting edge or cutting chips etc.Cool the affected area if receiving aburn injury from arc welding etc.

5. FIREFIGHTING MEASURESThe steel itself is in a non-flammable (solid) state. In the event of fire, fire extinguishers
and water may be used. However, steel in fine powder form may be combustible orExtinguishing media ： Use fire extinguishing media appropriate for the circumstances.
Extinguishing media to avoid ： No information
6. ACCIDENTAL RELEASE MEASURESThe steel itself is in a solid state, so no leakage will occur under normal circumstances.
In the event of the accidental release of dust or fumes during processing, etc., of steel
materials, the following measures are to be carried out.
・Personal precautions: Wear suitable protective equipment and avoid inhaling
dust or fumes or contact with eyes.
・Protective equipment and : Refer to protective equipment described in 8. “EXPOSURE
emergency procedures
CONTROLS/PERSONAL PROTECTION.”
・Environmental
precautions: Dust and similar residue generated by processing such as
cutting and polishing must be promptly collected.

page4 / 7

・Procedures and equipment : After using an appropriate method to recover dust
for containment andgenerated by steel processing,prevent accidental spillage.
cleanup
7. HANDLING AND STORAGE・Handling ：<Technical measures>
In cases in which steel is to be welded, fused, polished, etc., wear appropriate
protective equipment if dust, fumes, etc., may be generated. Additionally, if dust,fumes, etc., may be generated, use the necessary local exhaust and general< Precautions for safe handling>
Take care to prevent the overturn, collapse, or fall of heavy objects.
The cut ends, cuttings of steel, etc., may have burrs that could wound skin.
Arcs used in welding, fusing, etc., may cause burns.
When hoops and bands used in packaging are cut, the ends may spring up. Exercise
special care when handling coiled products as the ends are prone to spring up.
・Storage ：<Conditions for safe storage>
Avoid contact with water, acid, alkali, or any substances containing these.
Avoid environments of high temperature and high humidity. If necessary, use sheets,covers, and packaging to prevent rust or wetting by rainwater.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Since steel normally occurs in a solid state, there is no useful information regarding
exposure controls and personal protection under ordinary circumstances.
However, when steel is welded, fused, polished, cut, etc., dust and fumes are generated,so the following equipment measures and protective measures must be taken:
