First-aid measures
In case of inhalation of, ingestion of, or skin contact with the dust or fumes generated during processing of steel materials,
immediately give first aid described below, and then seek medical attention or treatment if necessary.

・ Inhalation: Move victim to fresh air and keep at rest in position comfortable for breathing.
・ Skin contact: Wash skin immediately with plenty of water and soap.
・ Eye contact: Rinse carefully with water for several minutes. In case of using contact lenses, remove them if easy to do so.
Continue rinsing.
・ Ingestion: Rinse mouth out thoroughly with water.
・ Others: In case of skin wound such as a cut from edge or chips of steel material, keep wound clean. If skin becomesburned by arcs, etc., cool with water.

5.

Fire-fighting measures
The product is non-combustible and non-explosive under normal conditions. Fire extinguishers/water may be used if in asituation of fire. However the fines of the products may be combustible or explosive depending on circumstances.

・ Suitable extinguishing media: Use extinguishing media appropriate for surrounding fire.
・ Unsuitable extinguishing media: No applicable information for this item.

6.

Accidental release measures
No available data to exposure prevention and protective measures for steel in solid state. However, with operations suchas welding, sawing, brazing, grinding, machining etc. that might case dust/fume, follow the procedures shown below.

6.1 Personal precautions, protective equipment, and emergency procedures
Provide adequate ventilation. Wear appropriate protective equipment to prevent inhalation of or eye contact with dust orfumes.
6.2 Environmental precautions
Not applicable to steel in solid state.
6.3 Methods and materials for containment and cleaning up
Contaminated packages must be disposed of as waste according to section 13.

7.

Handling and Storage

7.1 Precautions for safe handling
Wear appropriate protective equipment in case of generating dust or fumes during welding, weld cutting or grinding.
Moreover, be sure to provide local or general ventilation system.
For heavy weights, call for precautions in handling, against toppling, rolling and package-collapsing. Cut-ends and cutting
chips with burr may be injurious. Fumes from welding and fine particles may cause fire injury. When cutting bundling andpackaging hoops (bands), be careful about bouncing hoops and hoop-tips. Particularly with coils, be careful about theirleading ends which, when unbundled, might spring up ward.
7.2 Conditions for safe storage, including any compatibilities
Avoid contact with water leakage, acid, alkali or substances containing them. Avoid environment with high temperatureand high humidity. Pack them with sheets or covers to prevent products from getting rusty or rain water infiltrations, ifneeded.

8.

Exposure Controls/ Personal Protection
No available data to exposure prevention and protective measures for steel in solid state. However, with operations suchas welding, sawing, brazing, grinding, machining etc. that might case dust/fume, follow the exposure control/personal
protection procedures shown below.
