### 3. HAZARDS IDENTIFICATION

Potential Health Effects

General Overview

Product is in the form of odorless black powder and is not expected to cause environmental hazard under

good industrial hygiene plan.

Dusts from handling or proces sing may cause eye, skin and respiratory tract irritation when exposed.

Product contains small amount of metal oxides and consequently may produce an allergic reaction.

Wear appropriate personal protective equipment. Keep the product handling in confined space. Proper air

ventilation system is advised in handling the product.Eye

Contact with the eyes may cause irritation due to abrasive action of the dust. Not expected to cause

prolonged or significant eye irritation.

Skin

There is no known hazar d, but may be mildly irritating to the skin. It is not expected to cause prolonged or

significant irritation, even at high concentration. Not expected to be absorbed through the intact skin.

Inhalation

The dust from this material may cause respiratory irritation.

Ingestion

No known hazards. The product is not expected to be harmful if swallowed.

Acute and Chronic Health Effects

High concentration of dusts may be irritating to eyes, skin, mucus membranes and respiratory tract. No

applicable chronic information at this moment, but none of the components is known to be a carcinogen or a

suspected carcinogen.

Target Organ Effects

N o data

Developmental Information

There are no data available for assessing risk to the fetus from maternal exposure to this material.



### 4. FIRST AID MEASURES

General

Remove all contaminated clothing immediately.

Eyes

Hold the eyes open and rinse wit h water for a sufficiently long period of time (at least 10 minutes). Obtain

medical attention if pain, blinking or redness persists.

Skin

In case of skin contact, rinse thoroughly with soap and plenty of water. Obtain medical attention if irritation

per sists.Inhalation

If dusts are inhaled, move the person into fresh air, keep warm and allow to rest. If breathing is difficult,

oxygen may be administered and medical attention should be obtained.

Ingestion

Rinse mouth with water and obtain medical att ention.

### 6. ACCIDENTAL RELEASE MEASUR ES

Personal precautions

Equip cleanup crew with proper protection. Ensure adequate ventilation.Environmental precautions

Prevent entry to sewers and public waters

Spill Procedures

Sweep or vacuum according to normal housekeeping practices



### 7. HA NDLING AND STORAGE

General

Keep in closed container. Additional sealing may prevent accidental dust release

Precautions in handling and storage

Good ventilation of the workplace required. Contact with the skin and the eyes as well as inhalation of dust s

must be avoided

Storage

Keep only in the original container in a dedicated place

Handling

Handle in accordance with good industrial hygiene and safety procedures



### 8. EXPOSURE CONTROLS/PERSONAL PROTECTION

Eye Protection

Chemical goggles, safety gl asses or full

- faced shields

Skin Protection

Suits, gloves and other items of protective clothing. Protecting gloves including, for example: nitrile, latex,

and rubber

Respiratory Protections

Wear suitable respiratory equipment with High Efficiency Particulate Air Filter (HEPA), such as NIOSH

P100 filter, or air

- supplied respirators when directly exposed or handling the powder

Engineering Controls

Provide sufficient mechanical (general and/or local exhaust) ventilation for dustExposure Guidelines

In case of contact, ensure prompt removal from eyes, skin and clothing. Wash hands and other exposed

areas with mild soap and water before eat, drink or smoke and when leaving work



### 9. PHYSICAL A ND CHEMICAL PROPERTIES

10. STABILITY AND REACTIVITY

Stability

Thermal decomposition or combustion may produce smoke of carbon oxide and metal oxide

Incompatibility

Avoid contacting strong oxidizing and reducing agents. No hazardous reaction when used as directed.

Conditions to avoid

Avoid excessive heating (above 400 C) in oxygen rich atmosphere

Health Hazard Data

Experimentations performed on reconstituted human epidermis have shown no sign of toxicity of even very

large doses (full skin coverage for 24 hours) of oxidized carbon nanotubes (results to be published).

However, preliminary reports, based on pre

- studies on rats which were instill ed with severe, high

- level

doses of oxidized carbon nanotubes material, indicate that, if inhaled in large quantities, oxidized carbon

nanotubes are potentially toxic for humans. Such an exposure scenario is however unrealistic. Nevertheless

it is recommen ded that respiratory protection should be used to prevent inhalation exposure to oxidized

carbon nanotubes.



### 12. ECOLOGICAL INFORMATION

The product is not expected to present environmental hazard.



### 13. DISPOSAL CONSIDERATION

Disposal

As prepared the product is considered as non hazardous. It can then be either disposed in an approved

landfill or destroyed by incineration. Volatile dust must be collected during incineration. Liquids containing

significant amount of oxidized carbon nanotubes must be fi ltered before being released to the sewer.



### 14. TRANSPORT INFORMATION

Not regulated. Use precaution during transport in order to prevent accidental spill. Not dangerous cargo.

Keep separated from foodstuffs.
