Product Name: Potassium Chloride
Synonyms: Muriate of Potash, Sylvite
Chemical Formula: KCl
CAS Number: 7447-40-7
Recommended Use: Fertilizer, Laboratory Reagent, Food Additive, Industrial Processing
Supplier: Manufacturer/Supplier details available on product label
Emergency Contact: Refer to local emergency number or company emergency line
Classification: Not classified as hazardous under GHS for most consumer uses. Prolonged inhalation of dust can cause respiratory irritation.
GHS Label Elements: Not required for non-hazardous products but dust may require caution.
Routes of Exposure: Inhalation, ingestion, skin and eye contact.
Potential Health Effects: Eye irritation, mild skin irritation, respiratory tract discomfort in dusty environments. In large quantities by ingestion, can affect electrolyte balance, cause gastrointestinal upset, or more severe symptoms with very high intake.
Environment: Large releases may cause localized environmental harm especially in aquatic systems.
Chemical Name: Potassium Chloride
Concentration: 98–100%
Impurities: Trace amounts of sodium chloride, magnesium salts, and insoluble matter possible depending on source.
Molecular Weight: 74.55 g/mol
Inhalation: Move to fresh air, encourage deep breathing, seek medical advice if irritation persists.
Skin Contact: Wash affected area with plenty of water, remove exposed clothing, seek medical advice if irritation continues.
Eye Contact: Immediately rinse cautiously with water for several minutes, remove contact lenses, continue rinsing, and seek medical attention if irritation or discomfort remains.
Ingestion: Rinse mouth thoroughly, drink water, never induce vomiting unless directed by medical personnel, and seek advice if feeling unwell or experiencing abnormal symptoms.
Flammability: Potassium chloride does not burn.
Explosion Risk: Non-explosive under normal conditions.
Suitable Extinguishing Media: Use media suited to surrounding materials; water spray, foam, dry chemical, or carbon dioxide fire extinguishers are all appropriate.
Firefighter Protection: Wear protective gear and self-contained breathing apparatus for surrounding fire.
Thermal Decomposition: High temperatures may release toxic gases like hydrogen chloride or potassium oxides.
Personal Precautions: Wear dust mask or respirator, protective gloves, goggles, and avoid dust inhalation.
Environmental Precautions: Keep out of water sources and drains to prevent localized contamination.
Cleanup Methods: Collect spilled material by sweeping or vacuuming using methods to minimize dust, place in approved container for re-use or disposal. Ventilate area thoroughly after removal and wash area with water.
Handling: Avoid creating dust, keep containers closed, use in well-ventilated area, wear suitable protective equipment.
Storage: Store in a cool dry area, in tightly sealed containers, away from incompatible materials such as strong acids. Do not store near food, feed, or drinking water.
Special Precautions: Ensure good hygiene practices, avoid contact with moisture, prevent prolonged skin exposure.
Occupational Exposure Limits: No specific permissible exposure limit for potassium chloride; ACGIH nuisance dust limit 10 mg/m³ (total), 3 mg/m³ (respirable).
Engineering Controls: General room ventilation or local exhaust sufficient in most cases.
Personal Protective Equipment: Dust mask or respirator for dusty environments, safety goggles for eye protection, gloves for skin protection, wash hands after handling.
Additional Precautions: Use protective clothing if spillage or frequent handling is expected; eyewash station and safety shower recommended in work area.
Appearance: White or colorless crystalline powder or granules.
Odor: Odorless.
Melting Point: 770°C (1418°F).
Boiling Point: 1420°C (2588°F).
Solubility: Readily soluble in water.
Vapor Pressure: Not applicable.
Relative Density: 1.99 g/cm³
pH Value: Neutral (5% solution)
Other Data: Non-combustible, does not polymerize, stable at room temperature.
Chemical Stability: Stable under recommended conditions.
Conditions to Avoid: Contact with strong acids can release toxic gases.
Incompatible Materials: Strong acids (may produce hydrogen chloride gas), strong oxidizers.
Hazardous Decomposition Products: At high temperature, may release hydrogen chloride gas and potassium oxides.
Reactivity: Low under normal storage and handling.
Acute Toxicity: Oral LD50 (rat): ~2600 mg/kg. Low toxicity through acute exposure.
Chronic Toxicity: Overexposure by ingestion may alter heart rhythm, blood pressure, or gastrointestinal function in sensitive individuals.
Routes of Entry: Inhalation, ingestion, skin and eye contact.
Potential Effects: Large oral doses affect potassium balance and can damage organs if not medically managed; inhalation of dust may irritate; skin and eye contact may cause mild, reversible irritation.
Carcinogenic, Mutagenic, Reproductive Hazards: Not listed as carcinogen or mutagen, no reproductive hazards reported.
Toxicity: Not classified as hazardous to aquatic life in regular quantities; significant spills may harm freshwater organisms by altering salinity.
Persistence and Degradability: Inorganic compound, does not degrade biologically, remains in environment, soluble in water.
Bioaccumulation Potential: Unlikely, does not readily accumulate in biological tissues.
Mobility in Soil: High; mobile if released to ground or water.
Other Adverse Effects: Potassium ions at high concentrations disrupt aquatic plant and animal growth. Prevent major spills into surface water.
Waste Disposal Methods: Dispose of in compliance with local, regional, and national laws. Preferred option is reuse in compatible industrial or agricultural processes. If disposal is required, landfill as non-hazardous waste unless mixed with contaminants.
Packaging: Rinse empty containers, dispose or recycle according to regulations.
Sewage Disposal: Do not dump large quantities in sewers or untreated wastewater.
Special Precautions: Contact local waste management authorities for advice if material is contaminated.
UN Number: Not regulated for transport.
