Section IV.First Aid Measures
Eye ContactCheck for and remove any contact lenses. DO NOT use an eye ointment. Flush eyes with running water for a minimum
of 15 minutes, occasionally lifting the upper and lower eyelids. Seek medical attention. Treat symptomatically and
supportively.
Skin Contact
If the chemical gets spilled on a clothed portion of the body, remove the contaminated clothes as quickly as possible,
protecting your own hands and body. Place the victim under a deluge shower. If the chemical touches the victim's
exposed skin, such as the hands: Gently and thoroughly wash the contaminated skin with running water and non-abrasive
soap. Be particularly careful to clean folds, crevices, creases and groin. Cover the irritated skin with an emollient. Seek
medical attention. Treat symptomatically and supportively. Wash any contaminated clothing before reusing.
InhalationIf the victim is not breathing, perform artificial respiration. Loosen tight clothing such as a collar, tie, belt or waistband. If
breathing is difficult, oxygen can be administered. Seek medical attention. Treat symptomatically and supportively.
IngestionRemove dentures if any. Have conscious person drink several glasses of water or milk. INDUCE VOMITING by sticking
finger in throat. Lower the head so that the vomit will not reenter the mouth and throat. NEVER give an unconscious
person anything to ingest. Seek medical attention. Treat symptomatically and supportively.

Section VI.Accidental Release Measures
Spill CleanupIn case of a spill and/or a leak, always shut off any sources of ignition, ventilate the area, and exercise caution. Use a
Instructionsshovel to put the material into a convenient waste disposal container. Finish cleaning the spill by rinsing any
contaminated surfaces with copious amounts of water. Consult federal, state, and/or local authorities for assistance on
disposal.
DSD/Pictogra Handling and Storage
Handling and StorageKeep away from heat and sources of ignition. Mechanical exhaust required. When not in use, tightly seal the container
and store in a dry, cool place. Avoid excessive heat and light. DO NOT breathe dust. In case of insufficient ventilation,
Information
wear suitable respiratory equipment. If you feel unwell, seek medical attention and show the label when possible. Treat
symptomatically and supportively. Avoid contact with skin and eyes.
Always store away from incompatible compounds such as oxidizing agents.

Section VIII. Exposure Controls/Personal Protection
Engineering ControlsUse process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below
recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to
airborne contaminants below the exposure limit.
Personal ProtectionSplash goggles. Lab coat. Dust respirator. Boots. Gloves. A MSHA/NIOSH approved respirator must be used to avoid
inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling
this product.
