- burning of the dust in free air ( see N° 5 )


4 First aid measures
_________________________________________________________________________________________

After Inhalation:
- When large portions were inhaled, or when an Asthm attack starts,
one has to contact a doctor.

After skin contact :
- Rinse the afflicted zones with lots of water or take a shower.
- Take off the poluted clothes and wash them before re-using.
- Longer and repeated contacts with skin are to be avoided.
- After usage, take a bath .

After contact with eyes:
- Rinse minimum 15 minutes with water.

After swallowing:
- When a large amount was swallowed : provoque vomitting when the person;
has full consiousness
- Contact a doctor.


5 Fire-fighting measures
_________________________________________________________________________________________

Alloys of Cobalt- Chrome procure no danger for fire or explosion.
When such alloy it brought in very fine condition (dust), it could lead to Explosion in free air.

Fire extictors : Water, CO2, foam

Fire extinctors not to use for security reasons : none

Risks resulting from the burning or from ist gasses : poisonning ( see N° 11 )

Special fire extintor installations : respiratory device and protection
Clothing are recommended.


6 Accidental release measures
_________________________________________________________________________________________

Individual messures : avoid formation of dust

Messures for environment : not necessary

Cleaning methods : not necessary


7 Handling and storage
_________________________________________________________________________________________

Handling : Same caution as with all chemical substances.

Storage : No special messures required for storing the alloy .


8 Exposure controls / personal protection
_________________________________________________________________________________________

Extra indications on technical devices : ( see N° 7 )

Personal Protection equipment:

- Inhalation: When the solid form of the Nickel-Chrom-alloy,
during the Production, changes in dust or smoke,
keep the environmental conditions under the indicated limits;
( Cr < 0,050 mg/ m3 ; Co < 0,050 mg / m3 )
When the airconditionning is not sufficient, use a correct inhaling
protection.

- protection of hands: protection gloves

- Eye protection: protection glasses

- Skin protection: proper clothing

11 Toxicological information
_________________________________________________________________________________________

Under normal working conditions, the composition of Cobalt-Chrome alloys is not very Dangerous.
When small particals are formed, then there may be an acute toxicological risk

After inhaling : Very rare are Astm attacs due to the dust provoqued.
One can see some influences on the gastro intestinal and inhalation canals.

After skin contact : Cobalt-Chrome alloys could provoque inflammation or allergical reactions
to sensitive persons.

After eye contact : Inflammations, due to mechanical reasons.
Workers who were in contact with electolitical aerosols,
have shown eye inflammations.

After swallowing : Cobalt-Chrome alloys are not absorbed by the darm canals.
The swallowing of lots of alloy could procure intestinal pains,
Vomiting or poisonning.
When swallowing alloy over a long time span, kidny problems can arise.
