clothes and shoes. Immediate medical attention is required.
Inhalation Move to fresh air. Do not use mouth-to-mouth method if victim ingested or inhaled the
substance; give artificial respiration with the aid of a pocket mask equipped with a one-way
valve or other proper respiratory medical device. Immediate medical attention is required. If not breathing, give artificial respiration.

symptoms or breathing difficulties if inhaled. May cause allergic skin reaction. 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: Symptoms of allergic reaction may
include rash, itching, swelling, trouble breathing, tingling of the hands and feet, dizziness,

Oxidizer: Contact with combustible/organic material may cause fire. Risk of explosion if heated under confinement. Dust can form
an explosive mixture in air. Very toxic. Corrosive Material. Thermal decomposition can lead to release of irritating gases and
vapors. Keep product and empty container away from heat and sources of ignition. Do not allow run-off from fire fighting to enter
drains or water courses.
Hazardous Combustion Products
Nitrogen oxides (NOx) Highly toxic fumes Chromium oxide
Protective Equipment and Precautions for Firefighters
As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full
protective gear.

SECTION 6. ACCIDENTAL RELEASE MEASURES

Personal Precautions Wear self-contained breathing apparatus and protective suit. Evacuate personnel to safe areas. Ensure adequate ventilation. Avoid dust formation. Remove all sources of ignition.
Do not get in eyes, on skin, or on clothing.
Environmental Precautions Do not flush into surface water or sanitary sewer system. Do not allow material to contaminate ground water system. Prevent product from entering drains. Local authorities should be advised if significant spillages cannot be contained. Should not be released into the environment.
Methods for Containment and Clean Up
Wear self-contained breathing apparatus and protective suit. Keep combustibles (wood,
paper, oil, etc) away from spilled material. Remove all sources of ignition. Sweep up or
vacuum up spillage and collect in suitable container for disposal. Avoid dust formation.


SECTION 7. HANDLING AND STORAGE

Handling Use only under a chemical fume hood. Wear personal protective equipment. Avoid dust
formation. Do not get in eyes, on skin, or on clothing. Do not breathe dust. Do not ingest.
Keep away from clothing and other combustible materials. Keep away from open flames, hot surfaces and sources of ignition. Use spark-proof tools and explosion-proof equipment.
Storage Keep containers tightly closed in a dry, cool and well-ventilated place. Keep away from heat and sources of ignition. Do not store near combustible materials. Containers should be
vented periodically in order to overcome pressure buildup. Corrosives area.
