Not applicable.
Other Hazards

As steel, the product is physically and chemically stable in solid state under normal
environmental conditions.

At present, there is no useful hazard information related to physico-chemical hazards,
human health hazards, and environmental hazards.
Precautionary Statement[Safety Measures] Wear appropriate protective equipment to prevent dust and the like frombeing inhaled or getting into your eyes.
[First-aid Measures] If inhaled or in eyes, get medical advice if necessary.
[Storage] Avoid high temperature and humidity, and if necessary, cover the product with asheet to prevent penetration of rain water and rusting.
[Disposal] Dispose in the appropriate manner, such as recycling as scrap iron, in accordancewith laws and regulations.
In addition, it may also be necessary to take note of the following points.
1

・Since the product is a heavy load, pay attention to falling, rolling, load collapsing, etc.
・Cut end and chips of the steel material may hurt skin.
・Fume and dust generated from processing such as welding , fusing, and polishing may
irritate the respiratory organs, the eyes and other mucus membranes, or may cause disorders suchas pneumoconiosis.
・Fine powder of the product may combust or explode.

The concentration of the ingredients varies in the above range depending on the productspecification and type.
Other than the above ingredients, the product contains trace elements such as carbon (C),silicon (Si), phosphorus (P), and sulfur (S).
4. First-aid Measures
Since the normal state of the steel material is solid, situations requiring first-aid measures do
not occur under normal environmental conditions.
However, fumes and dust are generated when the product undergoes processing, etc. so, if thefollowing situation occurs, perform the first-aid measures shown below and then get medical advice2

as needed.
The following are examples of first-aid measures.
・If inhaled:
If breathing difficulties occur due to fumes and dust, remove victim to fresh air and keep atrest in a position comfortable for breathing.
・If on skin:If fume and dust are on skin, wash immediately with soap and copious amount of water.
・If in eyes:
If fume and dust get into the eyes, wash with water. If wearing contact lenses, remove them ifthey are easily removed. Then continue washing eyes.
・If swallowed:
If fume and dust are swallowed, drink copious amount of water, and rinse mouth.
・Other:写し

If skin is cut by chips and the like, wash the wound and keep it clean.

If the victim suffers burns due to arcs associated with welding and fusing, cool the affectedarea.

・The most important signs and symptoms in expected acute symptoms and delayed symptoms
Inhalation: cough, Eyes: redness

・Protection for persons giving first-aid measures: No information available.
・Special precautions for doctors: No information available.
5. Fire-fighting Measures

Since the normal state of the steel material is solid and it is incombustible, it does not combust
or explode under normal environmental conditions.

However, if dust or fine powder of chips and the like resulting from processing dries up or
accumulates deposits of fats and oils, it may combust or explode.

In the event of fire, wear protective equipment and extinguish the fire from the windward sideusing a fire-extinguishing agent.
・Fire-extinguishing media :There are no usage restrictions, so use a fire-extinguishing agent

that is suitable for the surrounding fire.
In case of dust or fine powder of chips and the like, do not spraywater directly, as it may cause a steam explosion.
However, there is no problem with spraying water on the area
which is not yet burning.
・Fire-extinguishing agent that should not be used: No information.
・Specific hazards: No information.
・Specific fire-extinguishing method: No information.
・Protection of fire-fighters: Wear appropriate protective equipment such as protective clothing
and air respirators when fire-fighting.

6. Accidental Release Measures
The normal state of the steel material is solid, so accidental release does not occur undernormal environmental conditions.
・Personal precautions, protective equipment and emergency measures:
Wear appropriate protective equipment to prevent dust and the like from being inhaled orgetting into the eyes.
・Environmental precautions:
Immediately collect the dust generated by processing, etc.
・Containment and Cleaning Methods and Equipment:
It is preferable for dust generated by processing and the like to be collected using a vacuum
cleaner, etc.
7. Handling and Storage
・Handling

写しTechnological measures: If dust and the like is generated by processing, etc., wear
appropriate protective equipment to avoid contact with eyes and skin, and prevent inhalation orswallowing.

In addition, provide necessary local and general ventilation.

Safe handling precautions: Since the product is a heavy load, pay attention to falling, rolling,load collapsing, etc.

Cut end, chips, and the like are sharp, so wear protective gloves.
Arcs associated with welding and fusing, etc. may cause burns,

so wear appropriate protective equipment.

Wash hands after handling.

・StorageTechnological measures: Provide the necessary daylight, lighting, and ventilation for storage
and handling at the storage place.

Dew condensation and the like may cause rust.
Safe storage conditions: Avoid contact of the product with moisture, acids and alkalis andsubstances containing them.
Avoid

rapid

temperaturechangesand

hotandhumid

environments.
If necessary, cover with a sheet to prevent penetration of rain waterand rusting, etc.

8. Exposure Control and Personal Protection
Since the normal state of the steel material is solid, no information corresponding to exposure
control and personal protection under normal environmental conditions is available.
However, when undergoing processing such as welding, fusing, polishing, and cutting for thisproduct, wear appropriate protective equipment such as goggles, gloves, masks, and clothes.
Ensure a proper work environment by providing appropriate local and general ventilation.
・Respiratory protective equipment: Wear appropriate respiratory protective equipment.
・Hand protective equipment: Wear appropriate protective gloves.
・Eye and/or face protection: Wear appropriate eye protective equipment.
If there is a possibility of flying particles or diffusing vapor coming
into contact with the eyes or face, wear chemical splash goggles or a face shield.
・Skin and body protective equipment: Wear appropriate protective equipment such as protective
clothes and safety shoes.
