GHS Pictograms:

Substance/Mixture: Substance

Chemical Name: Potassium Hydroxide

CAS Number: 1310-58-3

Concentration: ≥90% (anhydrous)

Note: No hazardous impurities present above reportable limits.

Inhalation: Move to fresh air. If breathing is difficult, administer oxygen and seek immediate medical attention.

Skin Contact: Remove contaminated clothing. Rinse skin with plenty of water for at least 15 minutes. Seek immediate medical attention.

Eye Contact: Rinse cautiously with water for at least 15 minutes, holding eyelids open. Remove contact lenses, if present and easy to do. Seek immediate medical attention.

Ingestion: Rinse mouth with water. Do not induce vomiting. Seek immediate medical attention or contact a POISON CENTER.

Most Important Symptoms: Severe burns to skin and eyes, respiratory irritation, gastrointestinal damage.

Immediate Medical Attention: Required for all exposures due to corrosive nature.

Suitable Extinguishing Media: Dry chemical, carbon dioxide (CO₂), or water spray.

Unsuitable Extinguishing Media: None known.

Specific Hazards: Non-flammable but may release toxic fumes (potassium oxide) upon heating. Reacts with water to generate heat.

Special Protective Equipment: Firefighters should wear self-contained breathing apparatus (SCBA) and protective clothing.

Fire-Fighting Instructions: Use water spray to cool containers and prevent pressure buildup.

Personal Precautions: Wear protective gloves, eye protection, and face shield. Ensure adequate ventilation. Avoid breathing dust or mist.

Environmental Precautions: Prevent release to sewers or waterways. Neutralize spills with dilute acid if permitted.

Methods for Containment and Cleanup: Sweep or vacuum up spilled material to avoid dust generation. Collect in suitable containers for disposal. Neutralize residue with dilute acid and rinse with water.

Handling Precautions:

• Use in well-ventilated areas to avoid inhalation of dust or mist.
• Avoid contact with skin, eyes, and clothing.
• Use appropriate containers resistant to corrosive materials.
• Handle with care to avoid heat generation when mixed with water.

Storage Conditions: Store in tightly sealed containers in a cool, dry, well-ventilated area away from acids, water, and metals. Keep between 5–30°C.

Exposure Limits: OSHA PEL: Not established. ACGIH TLV: 2 mg/m³ (ceiling, inhalable dust).

Engineering Controls: Use local exhaust ventilation or chemical fume hood to control dust or mist exposure.

Personal Protective Equipment (PPE):

• Eye Protection: Chemical safety goggles or face shield (OSHA 29 CFR 1910.133).
• Skin Protection: Chemical-resistant gloves, protective clothing, and boots.
• Respiratory Protection: Use a NIOSH-approved respirator if ventilation is inadequate (OSHA 29 CFR 1910.134).

Stability: Stable under recommended storage conditions. Hygroscopic; absorbs moisture from air.

Reactivity: Reacts exothermically with water, acids, and certain metals, producing heat and hydrogen gas.

Conditions to Avoid: Contact with water, acids, excessive heat, or incompatible materials.

Incompatible Materials: Acids, metals (e.g., aluminum, zinc), halogens, organic materials.

Hazardous Decomposition Products: Potassium oxide fumes upon heating.

Likely Routes of Exposure: Skin contact, eye contact, inhalation, ingestion.

Acute Effects:

• Inhalation: Causes severe respiratory irritation (LC50 not established).
• Skin Contact: Causes severe burns (Draize test, rabbit: corrosive).
• Eye Contact: Causes severe eye damage (Draize test, rabbit: corrosive).
• Ingestion: Harmful; causes burns to mouth and gastrointestinal tract (LD50 rat: 273 mg/kg).

Chronic Effects: Prolonged exposure may cause chronic skin or respiratory irritation.

Carcinogenicity: Not listed by ACGIH, IARC, NTP, or CA Prop 65.

Ecotoxicity: Harmful to aquatic life due to high pH (LC50 fish: 80 mg/L/96H).

Persistence and Degradability: Inorganic substance; does not biodegrade but dissociates in water.

Bioaccumulative Potential: Low potential.

Mobility in Soil: High mobility due to water solubility.

Dispose of in accordance with local, state, and federal regulations. Neutralize with dilute acid if permitted, and collect in suitable containers for disposal. Do not release into sewers or waterways.
