Repeated or prolonged exposure to this compound is not known to aggravate existing medical conditions.
Section IV. First Aid Measures
Eye Contact Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15
minutes. Get medical attention.
Skin Contact In case of contact, immediately flush skin with plenty of water. Remove contaminated clothing and shoes. Wash clothing
before reuse. Thoroughly clean shoes before reuse. Get medical attention.
Inhalation If the victim is not breathing, perform mouth-to-mouth resuscitation. Loosen tight clothing such as a collar, tie, belt or
waistband. If breathing is difficult, oxygen can be administered. Seek medical attention if respiration problems do not
improve.
Ingestion INDUCE VOMITING by sticking finger in throat. Lower the head so that the vomit will not reenter the mouth and throat.
Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform mouth-to-mouth
resuscitation. Examine the lips and mouth to ascertain whether the tissues are damaged, a possible indication that the
toxic material was ingested; the absence of such signs, however, is not conclusive.

Section VI. Accidental Release Measures
Spill Cleanup Harmful material. Irritating material.
Instructions Use a shovel 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.
Section VII. Handling and Storage
Handling and Storage HARMFUL. IRRITANT. Keep away from heat. 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.
Information
Always store away from incompatible compounds such as oxidizing agents.
Section VIII. Exposure Controls/Personal Protection
Engineering Controls Use 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 Protection Splash goggles. Lab coat. Dust respirator. Boots. Gloves. Suggested protective clothing might not be sufficient; consult
a specialist BEFORE handling this product. Be sure to use a MSHA/NIOSH approved respirator or equivalent.
