GHS Classification: Not classified as hazardous by GHS
Physical Hazards: Dust may cause mild irritation to eyes and respiratory tract. Not flammable. Not explosive.
Health Hazards: Eyes, skin, ingestion, and inhalation risks are generally low. Mild transient symptoms such as eye or skin discomfort if exposed.
Environmental Hazards: Significant release into waterways should be avoided, though the substance poses low risk to aquatic organisms.
Label Elements: Not an obligatory hazard-labeled product in most regulatory environments. Best handled using precautions for dust and ingestion.
Ingredient: Potassium Malate
Concentration: 98% or higher
Impurities: Trace (normally less than 1% by weight; typical food/pharma grade does not contain substances in concentrations requiring declaration under GHS)
Eye Contact: Rinse cautiously with plenty of water for several minutes. Remove contact lenses if present and easy to do. Medical attention for prolonged irritation.
Skin Contact: Wash with soap and water. Remove contaminated clothing. Seek medical advice if irritation persists.
Inhalation: Move person to fresh air. Support breathing with oxygen if breathing becomes difficult. Get medical attention if symptoms develop.
Ingestion: Rinse mouth. Do not induce vomiting. Medical support for persistent discomfort or if a large quantity is swallowed.
Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical, foam.
Specific Hazards: Thermal decomposition may yield carbon oxides and potassium compounds.
Special Protective Equipment: Firefighters wear self-contained breathing apparatus and suitable protective clothing. Product does not contribute to combustion.
Personal Precautions: Use appropriate respiration protection if dust generation likely. Avoid eye contact and prolonged skin exposure.
Environmental Precautions: Don’t flush to surface water or sewage system. Collect and dispose with respect to environmental regulations.
Methods for Cleanup: Sweep or vacuum up into suitable container. Wash area with water to remove residues, prevent dust dispersal.
Safe Handling: Use in well-ventilated areas. Wash hands after use. Minimize dust formation. Avoid eating and drinking during use.
Storage Requirements: Store in a dry, cool, well-ventilated place. Keep packaging tightly closed. Store away from strong oxidizers and acids. Maintain separation from food and feed materials.
Control Parameters: Occupational exposure limits for nuisance dust may apply (consult local workplace regulations).
Engineering Controls: Local exhaust or general room ventilation.
Personal Protective Equipment: Safety glasses or goggles, dust mask or respirator for airborne dust, lightweight gloves. Industrial hygiene—wash hands thoroughly after handling, change out of contaminated clothing.
