SHORT DESCRIPTION

Potassium Chlorate Extra Pure is a high-purity, crystalline compound with the chemical formula KClO₃. It appears as a white, odorless solid and is well known for its strong oxidizing properties. In its Extra Pure form, it meets analytical-grade standards, making it suitable for sensitive laboratory and controlled industrial applications.

This chemical is extensively used in analytical chemistry, especially in oxygen production experiments and thermal decomposition studies, as it decomposes to release oxygen when heated. It is also used as a reagent in pyrotechnics, match compositions, and explosive formulations, where a powerful oxidizer is needed. In botanical tissue culture, potassium chlorate is sometimes used to induce flowering in certain plant species.

Due to its reactive and potentially explosive nature, Potassium Chlorate must be handled with extreme caution. It should be stored away from combustible materials, acids, and heat sources, in a cool, dry, well-ventilated area, in tightly sealed containers. Personal protective equipment such as gloves, goggles, and lab coats must be worn during handling, and it should never be ground or mixed with sulfur, phosphorus, or organic matter unless under strictly controlled conditions.

SAFETY HANDLING PRECAUTIONS

SAFETY PRECAUTIONS

Personal Protective Equipment (PPE):

Use chemical-resistant gloves (e.g., nitrile).
Wear safety goggles and a face shield for full eye and face protection.
Lab coat and anti-static protective clothing recommended.
Use a suitable respirator if dust is generated.

Handling:

Handle in a spark-free, well-ventilated environment.
Avoid friction, heat, shock, or contact with organic materials.
Do not mix with combustible or reducing substances.
Prevent buildup of dust and avoid inhalation.

Storage:

Store in a tightly closed, corrosion-resistant container.
Keep in a cool, dry, and well-ventilated place.
Isolate from acids, organic materials, and flammable substances.
Label clearly as an oxidizer.

FIRST AID MEASURES

Inhalation:

Move people to fresh air.
Seek medical attention if respiratory symptoms develop.

Skin Contact:

Wash thoroughly with soap and water.
Remove contaminated clothing.
If irritation persists, consult a physician.

Eye Contact:

Rinse with copious amounts of water for at least 15 minutes.
Lift eyelids and flush thoroughly.
Seek immediate medical help.

Ingestion:

Rinse mouth with water.
Do NOT induce vomiting.
Seek immediate medical attention—may cause internal oxidative damage.

FIRE FIGHTING MEASURES

Flammability:

Not flammable by itself but a powerful oxidizer—can intensify fires.

Extinguishing Media:

Use water spray, dry chemical, or CO₂.
Avoid using dry combustible materials like sawdust or cloth.

Hazardous Combustion Products:

Releases toxic gases such as chlorine, potassium oxides, and oxygen under fire conditions.

Firefighter Protection:

Use full-body flame-resistant gear and self-contained breathing apparatus (SCBA).
Cool containers with water to prevent rupture.
Keep distance—risk of explosion if heated.
