Tool Steel (include the coated or surface treated Tool Steel)

2.1 Classification of the substance or mixture

Some data (such as the burning rate test data, etc.) for the dust, fume or vapor which occur from Tool Steel producing process are unavailable. Therefore, they are not be classified by GHS. In here, GHS classification of the each metallic ingredients (cobalt, nickel, chromium and manganese) for composing the Tool Steel can be disclosed. In addition, other hazards and harmful effects (for health, environment, physical and chemical) which are not listed are unclassifiable or non-applicable by GHS. GHS classification for the hazards of cobalt alone in below, (When cobalt is included as ingredients of Tool Steel.)

Response

If inhaled, move to fresh air and take a rest with posture easy to breathe. ･If respiratory symptoms occurs, contact a doctor. ･When feeling ill, get medical advice/attention. ･Take off contaminated clothing and wash before reuse. ･If on skin, rinse away immediately with a large amount of water and soap. ･If skin irritation occurs, contact a doctor and get medical advice/attention. ･If exposed or concerned, get medical advice/attention. ･If dust is in eyes, immediately wash away with clean water (remove the contact lenses if possible). If irritation persists, get medical advice/attention. ･If a large amount of dust is swallowed, get medical advice/attention after ingesting plenty of water to dilute.

Storage
