handling operations are not likely to cause injury; however, swallowing larger amounts may cause 

injury.

4. First-aid measures 

Description of first aid measures

General advice: If potential for exposure exists refer to Section 8 for specific personal protective 

equipment. 

Inhalation: Move person to fresh air; if effects occur, consult a physician. 

Skin Contact: Wash skin with plenty of water. 

Eye Contact: Flush eyes thoroughly with water for several minutes. Remove contact lenses after the 

initial 1-2 minutes and continue flushing for several additional minutes. If effects occur, consult a 

physician, preferably an ophthalmologist. Suitable emergency eye wash facility should be available in 

work area. 

Ingestion: If swallowed, seek medical attention. Do not induce vomiting unless directed to do so by 

medical personnel. 

Most important symptoms and effects, both acute and delayed

Aside from the information found under Description of first aid measures (above) and Indication of 

immediate medical attention and special treatment needed (below), no additional symptoms and 

effects are anticipated.

Indication of immediate medical attention and special treatment needed

No specific antidote. Treatment of exposure should be directed at the control of symptoms and the 

clinical condition of the patient. 

5. Fire Fighting Measures 

Suitable extinguishing media

Water fog or fine spray. Dry chemical fire extinguishers. Carbon dioxide fire extinguishers. Foam. 

Special hazards arising from the substance or mixture

Hazardous Combustion Products: During a fire, smoke may contain the original material in addition 

to combustion products of varying composition which may be toxic and/or irritating. Combustion 

products may include and are not limited to: Carbon monoxide. Carbon dioxide. 

Unusual Fire and Explosion Hazards: Pneumatic conveying and other mechanical handling 

operations can generate combustible dust. To reduce the potential for dust explosions, do not permit 

dust to accumulate. 

Advice for firefighters

Fire Fighting Procedures: Keep people away. Isolate fire and deny unnecessary entry. Soak 

thoroughly with water to cool and prevent re-ignition. If material is molten, do not apply direct water 

stream. Use fine water spray or foam. Cool surroundings with water to localize fire zone. Hand held 

dry chemical or carbon dioxide extinguishers may be used for small fires. 

Special Protective Equipment for Firefighters: Wear positive-pressure self-contained breathing 

apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat, trousers, 

boots, and gloves). If protective equipment is not available or not used, fight fire from a protected 

location or safe distance.

6. Accidental Release Measures 

Personal precautions, protective equipment and emergency procedures: Isolate area. Keep 

unnecessary and unprotected personnel from entering the area. Refer to Section 7, Handling, for 

additional precautionary measures. Use appropriate safety equipment. For additional information, 

refer to Section 8, Exposure Controls and Personal Protection. 

Environmental precautions: Prevent from entering into soil, ditches, sewers, waterways and/or 

groundwater. See Section 12, Ecological Information. 

Methods and materials for containment and cleaning up: Contain spilled material if possible. 

Collect in suitable and properly labeled containers. See Section 13, Disposal Considerations, for 

additional information. 

7. Handling and Storage 

Handling 

General Handling: Avoid contact with eyes. Wash thoroughly after handling. Good housekeeping 

and controlling of dusts are necessary for safe handling of product. See Section 8, EXPOSURE 

CONTROLS AND PERSONAL PROTECTION. 

Storage 

Store in accordance with good manufacturing practices. 

Shelf life: Use within 24 Months 

8. Exposure Controls / Personal Protection 

Exposure Limits

None established 

Personal Protection

Eye/Face Protection: Use safety glasses (with side shields). 

Skin Protection: Wear clean, body-covering clothing. 

Hand protection: Use chemical resistant gloves classified under Standard EN374: Protective 

gloves against chemicals and micro-organisms. Examples of preferred glove barrier materials 

include: Butyl rubber. Chlorinated polyethylene. Polyethylene. Ethyl vinyl alcohol laminate 

(“EVAL”). Polyvinyl alcohol (“PVA”). Examples of acceptable glove barrier materials include: 

Natural rubber (“latex”). Neoprene. Nitrile/butadiene rubber (“nitrile” or “NBR”). Polyvinyl 

chloride (“PVC” or “vinyl”). Viton. When prolonged or frequently repeated contact may occur, 

a glove with a protection class of 5 or higher (breakthrough time greater than 240 minutes 

according to EN 374) is recommended. When only brief contact is expected, a glove with a 

protection class of 3 or higher (breakthrough time greater than 60 minutes according to EN 

374) is recommended. NOTICE: The selection of a specific glove for a particular application 

and duration of use in a workplace should also take into account all relevant workplace factors 

such as, but not limited to: Other chemicals which may be handled, physical requirements 

(cut/puncture protection, dexterity, thermal protection), potential body reactions to glove 

materials, as well as the instructions/specifications provided by the glove supplier. 

Respiratory Protection: Respiratory protection should be worn when there is a potential to exceed 

the exposure limit requirements or guidelines. If there are no applicable exposure limit requirements 

or guidelines, wear respiratory protection when adverse effects, such as respiratory irritation or 

discomfort have been experienced, or where indicated by your risk assessment process. For most 

conditions no respiratory protection should be needed; however, if discomfort is experienced, use an 

approved air-purifying respirator. The following should be effective types of air-purifying respirators: 

Organic vapor cartridge with a particulate pre-filter.

Ingestion: Use good personal hygiene. Do not consume or store food in the work area. Wash hands 

before smoking or eating. 

Engineering Controls

Ventilation: Use local exhaust ventilation, or other engineering controls to maintain airborne levels 

below exposure limit requirements or guidelines. If there are no applicable exposure limit 

requirements or guidelines, general ventilation should be sufficient for most operations. Local exhaust 

ventilation may be necessary for some operations.
