3. Hazards Identification
Emergency Overview
Strong oxidizer! contact with other material may cause fire. Under fire conditions this
material may decompose and release oxygen that intensifies fire.
Potential Health Effects
Inhalation................. Irritating to the respiratory tract. Causes chemical burns.
Eye contact............... May cause irritation to the eyes. May cause eye burns.
Skin contact.............. May cause skin irritation and burns
Ingestion.................. May cause severe and permanent damage to the digestive tract.
Causes gastrointestinal tract burns.
4. First-aid Measures
Remove affected person to fresh air. Do not use mouth-to mouth
Inhalation.................
resuscitation. Seek medical attention if effects persist.
Flush eyes with running water for at least 15 minutes with eyelids
Eye contact...............
held open. Seek specialist advice immediately.
Skin contact.............. Wash affected skin with soap and mild detergent and large
amounts of water.
Ingestion.................. Remove from exposure to fresh air immediately. If breathing is
difficult, give oxygen. Do not use mouth-to-mouth resuscitation.
Seek medical service immediately.

Fire Hazards
Oxidizer. Storage vessels involved in a fire may vent gas or rupture due to internal pressure.
Damp material may decompose exothermically and ignite combustibles. Oxygen release due
to exothermic decomposition may support combustion. May ignite other combustible
materials. Avoid contact with incompatible materials such as heavy metals, reducing agents,
acids, bases, combustibles (wood, papers, cloths etc.). Thermal decomposition releases
oxygen and heat. Pressure bursts may occur due to gas evolution. Pressurization if confined
when heated or decomposing. Containers may burst violently.
Fire-Fighting Measures
Evacuate all non-essential personnel
Wear protective clothing and self-contained breathing apparatus
Remain upwind of fire to avoid hazardous vapors and decomposition products
Use water spray to cool fire-exposed containers
6. Accidental Release Measures
Spill Clean-up Procedures
Oxidizer. Eliminate all sources of ignition. Evacuate unprotected personnel from equipment
recommendations found in Section 8. Never exceed any occupational exposure limit.
Shovel or sweep material into plastic bags or vented containers for disposal. Do not return
spilled or contaminated material to inventory.
Flush remaining area with water to remove trace residue and dispose of properly. Avoid
direct discharge to sewers and surface waters. Notify authorities if entry occurs.
Do not touch or walk through spilled material. Keep away from combustibles (wood, paper,
oils, etc.). Do not return any product to container because of the risk of contamination.
7. Handling and Storage
Storage
Oxidizer. Store in a dry, well ventilated area away from all source of ignition and out of
direct sunlight. Store in a dry location away from heat. Store at room temperature
(15癈~25癈 is recommended).
2
Keep away from incompatible materials. Keep containers tightly closed. Do not store in
unlabeled or mislabeled containers. Never return unused product to storage container.
Protect from moisture. Do not store near combustible materials. Keep containers well sealed,
seal only with original vent cap. Ensure pressure relief and adequate ventilation.
Store separately from organics and reducing materials. Avoid contamination which may lead
to decomposition.
Handling
Avoid contact with eyes, skin, and clothing. Use with adequate ventilation.
Do not swallow. Avoid breathing vapors, mists, or dust. Do not eat, drink, or smoke in work
area.
Prevent contact with combustible or organic materials.
Label containers and keep them tightly closed when not in use.
Wash thoroughly after handling.
8. Exposure Controls/Personal Protection
Engineering Controls
General room ventilation is required. Local exhaust ventilation, process enclosures or other
engineers controls may be needed to maintain airborne levels below recommended exposure
limits. Avoid creating dust or mist. Maintain adequate ventilation. Do not use in closed or
confined spaces. Keep levels below exposure limits. To determine exposure levels,
monitoring should be performed regularly.
Respiratory Protection
For many conditions, no respiratory protection may be needed; however, in dusty or
unknown atmospheres or when exposures exceed limit values, wear a NIOSH approved
respirator.
Eye/Face Protection
Wear chemical safety goggles and a full face shield while handling this product.
Skin Protection
Prevent contact with this product. Wear gloves and protective clothing depending on
condition of use.
Other Protective Equipment
Eye-wash station
Safety shower
Impervious clothing
Rubber boots
General Hygiene Considerations
Wash with soap and water before meal times and at the end of each work shift. Good
manufacturing practices require gross amounts of any chemical be removed from skin as
soon as practical, especially before eating or smoking.
