MSDS FOR HARD CARBON

1). Identification of the substance/preparation Product details:

Name: Anode Materials (BHC)

2). Hazards identification Potential health Effects Eye May cause eye irritation.

Skin May cause skin irritation.

Inhalation May cause respiratory tract irritation.

Ingestion No hazard in normal industrial use.

Cancer None of the components present in this material at concentrations equal or greater than 0.1% are listed by IARC, NTP, OSHA or ACGIH as a carcinogen.

3.) Composition / information on ingredients Chemical characterization Synthetic graphite powder, free of crystalline silica (quartz) Substance / product identification CAS no. 7782-42-5 Molecular weight 12.01Formula C

4.) First aid measures General information In case of persisting adverse effects, consult a physician. Remove contaminated clothing and shoes immediately, and launder thoroughly before reusing.

After inhalation Remove from exposure. Remove to fresh air. If not breathing, give artificial if breathing is difficult give Oxygen. Get medical attention.

After skin contact Wash with soap and water.

After eye contact Hold eyelids apart and flush eyes with plenty of water for at least 15 minutes.

After ingestion Rinse mouth thoroughly with water. Seek medical advice immediately. Never give anything by mouth to an unconscious person.

5.) Firefighting measures Suitable extinguishing media Graphite is difficult to combust. Extinguishing measures to suit surroundings.

Special exposure hazards arising from the substance or preparation itself, its combustion products or from resulting gases In the event of fire, the following can be released:

Carbon monoxide (CO) Carbon dioxide (CO2)

Special protective equipment for firefighting As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/ NIOSH (approved or equivalent) and full protective gear.

6.) Accidental release measures Personal precautions Refer to protective measures listed in sections 7 and 8. Avoid contact with skin, eyes and clothing.

Ensure adequate ventilation. Avoid dust formation. High risk of slipping due to leakage/spillage of products.

Environmental precautions Do not discharge into the drains/surface waters/groundwater.

Methods for cleaning up/taking up Pick up mechanically. Send in suitable containers for recovery or disposal.

7.) handling and storage Handling Advice on safe handling Provide good ventilation of working area (local exhaust ventilation if necessary). If workplace exposure limits are exceeded, respiratory protection approved for this particular job must be worn.

Advice on protection against fire and explosion Dust can form an explosive mixture with air. Take precautionary measures against static charges.

Keep away from sources of heat and ignition.

Storage Requirements for storage rooms and vessels Containers which are opened must be carefully resealed and kept upright to prevent leakage. Always keep in containers of same material as the original one.

Further information on storage conditions Keep container tightly closed and dry.

8.) Exposure controls/ personal protection Exposure limit values

GRAPHITE

CAS no. 7781-42-5 ES no. 231-955-3

ACGIH

Graphite (all forms except graphite fibers) TWA 2 mg/m3

LIMITS FOR AIR CONTAMINANTS (OSHA)

Graphite, natural respiratary dust TWA 15 ml/m3 Personal protective equipment

Respiratory protection A respiratory protection program that meets OSHA’s 29 CFR 1910.134 and ANSI Z88.2 requirements must be followed whenever workplace conditions warrant a respirator’s use.

Hand protection Wear appropriate gloves to prevent skin exposure. Before use, the protective glove should be tested in any case for its specific work-station suitability (i.e. mechanical resistance, product compatibility and antistatic properties). Adhere to the manufacturer’s instructions and information relating to the use, storage, care and replacement of protective gloves. Protective gloves shall be replaced immediately when physically damaged or worn. Design operations thus to avoid permanent use of protective gloves. The glove(s) listed below may provide protection against permeation. Gloves of other chemically resistant materials may not provide adequate protection.

Appropriate Material rubber

Eye protection Wear appropriate protective eyeglasses or chemical safety goggle as described by OSHA’s eye and face protection regulations in 29 CFR 1910.133.

Skin protection Wear appropriate clothing to minimize contact with skin.

General protective and hygiene measures Do not eat, drink or smoke during work time. Keep away from foodstuffs and beverages. Avoid contact with eyes and skin. Remove soiled or soaked clothing immediately. Wash hands before break and after work. Do not inhale dust. Hold eye wash fountain available.
