SECTION 4. FIRST AID MEASURES
Eye Contact Immediate medical attention is required. Rinse immediately with plenty of water, also under
the eyelids, for at least 15 minutes.
Skin Contact Wash off immediately with plenty of water for at least 15 minutes. Immediate medical
attention is required.
Inhalation Move to fresh air. If breathing is difficult, give oxygen. Get medical attention immediately if
symptoms occur.
Ingestion Do not induce vomiting. Obtain medical attention.
Most important symptoms/effects Breathing difficulties. Causes burns by all exposure routes. Inhalation of high vapor
concentrations may cause symptoms like headache, dizziness, tiredness, nausea and
vomiting: Product is a corrosive material. Use of gastric lavage or emesis is
contraindicated. Possible perforation of stomach or esophagus should be investigated:
Ingestion causes severe swelling, severe damage to the delicate tissue and danger of
perforation
Notes to Physician Treat symptomatically

SECTION 6. ACCIDENTAL RELEASE MEASURES
Personal Precautions Ensure adequate ventilation. Use personal protective equipment.
Environmental Precautions See Section 12 for additional ecological information.
Methods for Containment and Clean Up
Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder,
sawdust). Keep in suitable, closed containers for disposal. Remove all sources of ignition.
Use spark-proof tools and explosion-proof equipment. Do not expose spill to water.
SECTION 7. HANDLING AND STORAGE
Handling Do not breathe vapors or spray mist. Do not get in eyes, on skin, or on clothing. Use only in
area provided with appropriate exhaust ventilation. Use explosion-proof equipment. Use
only non-sparking tools. Do not allow contact with water because of violent reaction. Keep
away from open flames, hot surfaces and sources of ignition. To avoid ignition of vapors by
static electricity discharge, all metal parts of the equipment must be grounded. Take
precautionary measures against static discharges. If peroxide formation is suspected, do
not open or move container.
Storage Keep in a dry place. Keep container tightly closed. Keep away from heat and sources of
ignition. Keep away from direct sunlight. Store at room temperature. Never allow product to
get in contact with water during storage. Corrosives area. Flammables area. Keep under
nitrogen. Keep container tightly closed in a dry and well-ventilated place. Containers should
be dated when opened and tested periodically for the presence of peroxides. Should
crystals form in a peroxidizable liquid, peroxidation may have occurred and the product
should be considered extremely dangerous. In this instance, the container should only be
opened remotely by professionals.
