４ Hazards Identification
Fire Defense Law of Japan: Hazards Group Ⅰ
Physical And Chemical Hazards
Danger:
Direct contact with the substances mentioned below may cause decomposition of material
and fire or explosion.
Fire, heat, acid, alkali, organic solvent, reducing agent and other combustible material like
oil&fat, grease.
Contact with those above may cause degradation of material and fire or explosion.
Contact with inorganic bleaching powder, ammonia and ammonium salt may generate
hazardous and explosive gases.
Potential Health Effects:
Eye contact may cause irritation and pain burns.
Skin contact may cause irritation and prolonged contact may cause burns.
Inhalation may cause irritation, choking and damage to respiratory tract, mucous membranes.
Ingestion may cause damage to mucous membranes and digestive tract.
Potential Environmental Effects
Material is believed not to persist in the environment. Hydrolysis reaction occurs in water.
Odor： Chlorine-like odor
Classification： Oxidizing substance

Classification of Danger and Harmfulness

Name of Classification
: Oxidizing Substances
Danger : They are applicable under theⅠgrade dangerous articles of the
Fire Services Act.
If they are exposed to heat, or touch grease, oil, deoxides, and
other flammable materials,they dissolve and they may cause fire
or an explosion.
If they are mixed with organo bleaching powder ( chlorinated
isocyanuric acid) they produce harmful and explosive gas.
Harmfulness : In case of personal contact, they irritate eyes and roughen
skin.
If swallowed, mucus problems will occur.
Effective environment
: They gradually dissolve in water.

５ First Aid Measures

Inhalation
Immediately remove the victim to fresh air or uncontaminated area.
Call immediately emergency services and medical assistance.
Eye Contact
Immediately wash thoroughly with running water, eyes and upper/lower lids for at least
15minutes.
Immediately get Medical Attention.
Skin Contact
Immediately remove clothes and/or wash contaminated area with running water.
Wash contaminated area with soap and running water for at least 15 minutes.
Immediately get Medical Attention.
Ingestion
Immediately get Medical Attention.
When conscious, drink plenty of water or milk and vomit.
When unconscious, do not force to vomit.

６ Fire Fighting Measures
Fire And Explosion Hazards
Extinguish Media
Large amount of water.
Do not use any dry chemicals, carbon dioxide, halogenated extinguishing agent
In case of fire
Evacuate to the safe areas where supposed locations of upwind and high.
Move container from fire area if safety ensured.
If not, spray large amount of water to cool container to prevent from vapor/rupture.
Spraying water may also help gas/vapor disperse wider.
Extinguishing action
Extreme caution is needed if to do.
Wear thoroughly protective clothing and self-contained breathing apparatus.
Avoid inhalation of material and gas/vapor.
Damp material must be neutralized thoroughly before waste and also contaminated
water must be neutralized.

７ Accidental Release Measures

In case of spill
Clean up immediately.
Wear gloves when touch spilled material.
Action to clean up
Wear appropriate protective clothing and equipment.
Keep unnecessary person away.
Do not use water to spilled material.
Scoop spilled material into clean, dry container and sweep spilled area thoroughly.
Extreme care to prevent from any contamination with combustible or organic material.
Do not return spilled material to original container.
Prevent material from get into sewers, waterways and rivers.
Caution to release
Do not damp spilled material.
Damp/wet material must be neutralized thoroughly before release.

８ Handling And Safety

Handling
Wear appropriate protective clothing and equipment.
Do not get in eyes, on skin, or on clothing.
Avoid breathing vapor, hume, dust of material.
Handle container with care not to damage.
Avoid generate mist and dust.
Ensure adequate ventilation.
Prevent from contact with inorganic bleaching powder, ammonia and ammonium salt.
Prevent from any contamination and contact with combustible or organic material.
Prevent from contact with fire, heat, acid, alkali, grease.
Wash thoroughly body and clothing after handling.
Storage
Store in tightly closed container in clean, dry, cool and well-ventilated area.
Do not allow water/humidity get into container.
Prevent from contact with ammonia.
Store away from fire, heat, acid, alkali, grease, oil, deoxides, incompatible material and
combustible material
Isolate from Chlorinated isocyanuric acid.
Recommend to keep container on pallet, in dark place avoiding direct exposure to sunlight.
Keep temperature below 40 ℃.
