Inhalation: Move affected person to fresh air, monitor for persistent coughing, seek medical advice if symptoms escalate
Eye Contact: Rinse carefully with plenty of water for several minutes, remove contact lenses, obtain medical attention if redness continues
Skin Contact: Wash skin thoroughly with soap and water, apply moisturizing lotion to soothe irritation
Ingestion: Drink water to dilute, do not induce vomiting, consult a physician if large quantities swallowed
Notes for Physician: Symptomatic treatment, focus on respiratory or ocular support if irritation is severe
Suitable Extinguishing Media: Use media appropriate for surrounding fire, bentonite itself does not burn
Unsuitable Media: None of significant concern, not reactive with common extinguishers
Specific Hazards: Dust may contribute to visibility reduction in confined spaces; product does not release toxic gases under fire
Protective Equipment: Wear standard firefighting gear, use NIOSH-approved respirator in high-dust settings
Special Precautions: Control dust to prevent respiratory complications, ensure fire exits remain accessible
Personal Precautions: Wear masks or goggles to avoid dust inhalation and eye contact
Spill Cleanup Methods: Sweep or vacuum up gently, avoid creating airborne dust, use damp cloths for fine residue
Environmental Precautions: Prevent runoff into waterways, collect and dispose in accordance with municipal or industrial waste protocols
Decontamination: Wash hands and exposed skin after cleanup, ventilate area thoroughly
Handling Guidance: Use with adequate ventilation, minimize dust generation, employ local exhaust if dust levels rise
Personal Hygiene: Wash after handling, don’t eat or smoke while working with bentonite
Incompatible Materials: None of major significance, safe with steel or plastic storage bins
Storage Requirements: Store in a cool, dry area, containers tightly closed to keep moisture out
Bulk Storage Tips: Invest in moisture-resistant packaging, label clearly with handling instructions and shelf life
Occupational Exposure Limits: OSHA PEL for respirable dust: 5 mg/m³
Engineering Controls: Install local exhaust ventilation, control dust at source
Personal Protection: Dust-proof goggles, N95 dust masks, gloves for prolonged exposure
Workplace Monitoring: Regular air sampling in manufacturing or packing zones
Hygiene Measures: Wash thoroughly before eating, keep workspaces uncluttered and clean
