2. Hazards Identification
2.1 Danger from Fire
Diamond is non flammable when it is in a solid state, thus there is no chance to be acause of fire. However dust from grinding has the possibility of spontaneous ignition or explosion.
Flash point, flammable limits and explosion limits have not been found.
2.2

Toxicity
There is the possibility of irritation when dust from grinding contacts the skin or eyes .
It is reported that repetition or long periods in contact with of, may influence the to skin,respiratory organs, heart, etc.

4. Emergency and First Aid Procedures
4.1

Inhalation
If high concentrations are inhaled or the worker exhibits trouble breathing (cough, pant, etc),
remove to fresh air. If breathing is difficult, administer oxygen.
If breathing has stopped, try artificial respiration. Seek immediate medical attention.
If irritation or a rash is continuous for a long period , seek medical attention.

4.2

Skin Contact
When grind dust contacts the skin, remove the contaminated clothes and clean the skin with soapand water. If irritation or a rash is continuous for a long period , seek medical attention.

4.3

Eye Contact
When ground dust gets in eye flush with running water. If the irritation persists , seek medicalattention.

4.4

Ingestion
When a large volume of dust is swallowed drink plenty of water to dilute and seek immediate
medical attention.

5. Fire Procedures
5.1

Fire Extinguisher
When ignition of grinding dust occurs , use dry sand, dry muscovite, ABC type (for general,oil and electricity fire) powder fire extinguisher or water.

5.2

Unusual Fire and Explosion
If dust from grinding is in a special condition, for example it has a very small particle size and ismixed with low flash point grinding oil, it might spontaneous ignite. If this dust in this conditionis then sprayed in the air it might reach the explosion point.

5.3

Fire fighter's protection
Use dust-proof mask or self contained breathing apparatus.

6. Spill and Leak Procedures
6.1

Attention to the Human Body
Clean-up personnel should wear personal protective equipment including respiratory protection
which is appropriate for the magnitude of exposure.

6.2

Attention to the Environment2Document Number：SHM-DIA-DA02-1
Dust must be treated as an industrial waste and must not leak to the water system.
6.3

Removal Procedures
For removal of dust from the grinding and machining operation, isolate area and do not walkthroughelse material will get scattered. Remove dust using a vacuum equipped with a filter
sufficient to remove metal dust and prevent their circulation (a high efficiency particulate air(HEPA) filter is recommended). If an appropriate vacuum is unavailable, use mist , a wet dust mopor another wet clean-up method to remove the dust.

7. Handling and Storage
7.1

Handling
CVD Single Crystal Diamond is stable thus there is almost no effect to the human health,but long time or repetitive contact to dust or grinding liquid may damage the skin.
When grinding or machining CVD Single Crystal Diamond contained dust may be dispersed,
use extraction to minimize the dust exposed to workers. Remove ground sludge as well as dust.
Wash hands thoroughly before eating, drinking and smoking. Do not eat, drink and smoke in theCVD Single Crystal Diamond handling area.
A periodic medical check-up is recommended.

7.2. Storage
Avoid drastic changes of temperature and high humidity.
Provide local exhaust ventilation system, or use respiratory protective equipment and/or dust mask
to maintain suspended dust particles concentration level, below the limits shown in the followingtable.

8. Exposure Controls and Personal Protection
Use a dust protective mask and a respirator, and set up local exhaust ventilation to prevent airborne
dust which exceeds the permissible level on the following table.

8.2

Respiratory protection
It is recommended to wear respiratory protective equipment or dust mask for protection against dust.

8.3

Hands protection

3Document Number：SHM-DIA-DA02-1
It is recommended to wear protective gloves for protection against dust.
8.4

Eye protection
It is recommended to wear protective glasses or chemical safety goggles for protection against dust.

8.5

Skin and body protection
Avoid direct contact of dust with skins.
In order to remove attached dust, do not shake off clothes or pieces of cloth, but be sure to remove
dust by laundering or absorbing with a vacuum cleaner with suitable filters. Change contaminatedclothes to clean clothes. It is recommended to use local exhaust ventilation system.
