- Common names and synonyms: Potassium chlorate
- CAS number: 3811-04-9
- EC number: 223-289-7

SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest. Refer for medical attention.
First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention .
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Refer immediately for medical attention.
Most important symptoms/effects, acute and delayed
Inhalation of dust can irritate nose and throat. Contact with eyes or skin causes irritation. Ingestion causes abdominal pain, nausea, vomiting, cyanosis, collapse. (USCG, 1999)
Excerpt from ERG Guide 140 [Oxidizers]: Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution. (ERG, 2016)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Chlorates and Related Compounds
SECTION 5: Firefighting measures
Suitable extinguishing media
Not combustible, but substance is a strong oxidizer and its heat of reaction with reducing agents or combustibles may cause ignition. When heated, it releases oxygen which increases combustion. Use any means suitable for extinguishing surrounding fire. Water spray may be used to keep fire exposed containers cool. In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.
Specific hazards arising from the chemical
Special Hazards of Combustion Products: Toxic fumes are formed in fires. Behavior in Fire: Decomposes when hot to form oxygen, which increases severity of fire. (USCG, 1999)
Excerpt from ERG Guide 140 [Oxidizers]: These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard. (ERG, 2016)
Special protective actions for fire-fighters
In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Consult an expert! Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Do NOT absorb in saw-dust or other combustible absorbents.
Environmental precautions
Consult an expert! Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Do NOT absorb in saw-dust or other combustible absorbents.
Methods and materials for containment and cleaning up
Accidental Release Measures. Remove all sources of ignition. Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Clean up spills in a manner that does not disperse dust into the air. Use non-sparking tools and equipment. Reduce airborne dust and prevent scattering by moistening with water. Pick up spill for recovery or disposal and place in a closed container.
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames. NO contact with flammables. NO contact with hot surfaces. Do NOT expose to friction or shock. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Separated from combustible substances, reducing agents, strong acids, organic chemicals, ammonium compounds, powdered metals and food and feedstuffs. Dry.... Containers of potassium chlorate should be protected from physical damage and sudden shocks.

SECTION 9: Physical and chemical properties and safety characteristics
-
Physical state：
Potassium chlorate is a white crystalline solid. Forms a very flammable mixture with combustible materials. Mixture may be explosive if combustible material is very finely divided. Mixture may be ignited by friction. Contact with strong sulfuric acid may cause fires or explosions. May spontaneously decompose and ignite when mixed with ammonium salts. May explode under prolonged exposure to heat or fire. Used to make matches, paper, explosives, and many other uses.

SECTION 10: Stability and reactivity
Reactivity
Decomposes above 400°C . Decomposes on contact with strong acids. This produces oxygen and toxic fumes including chlorine dioxide and chlorine. The substance is a strong oxidant. It reacts violently with combustible and reducing materials. This generates fire and explosion hazard. Attacks many metals in the presence of water.
Chemical stability
Stable under ordinary conditions of use and storage.
Possibility of hazardous reactions
Not flammable, but may cause fire upon contact with ordinary combustibles.Metal chlorates are oxidants in the presence of strong acid; liberates explosive chlorine dioxide gas; liberates chlorine dioxide and carbon dioxide by heating a moist metal chlorate and a dibasic organic acid; mixtures of perchlorates with sulfur or phosphorus are explosives [Bretherick 1979 p. 100]; mixtures of the chlorate with ammonium salts, powdered metals, silicon, sulfur, or sulfides are readily ignited and potentially explosive [Bretherick 1979 p. 806]. A combination of finely divided aluminum with finely divided bromates (also chlorates and iodates) of barium, calcium, magnesium, potassium, sodium, or zinc can explode by heat, percussion, or friction [Mellor 2:310. 1946-47]. An explosion occurred during heating of a mixture of potassium chlorate and magnesium [Chem. Eng. News 14:451. 1936]. Gaseous ammonia, mixed with air reacts so vigorously with potassium chlorate that the reaction could become dangerous [Mellor 8:217. 1946-47]. A mixture of potassium chlorate and sodium amide explodes [Mellor 8:258. 1946-47]. If a drop of a solution of sulfur dioxide in ether or alcohol is added to powdered potassium chlorate, the mass explodes [Mellor 2:311. 1946-47]. Potassium chlorate and sulfuric acid react to cause fire and possible explosions [Mellor 2:315. 1946-47].
