May use safety eyewear to protect from dusts. Gloves: Normally not required. May use gloves to protect overly sensitive skin. Respirator: Even though Perlite is a nuisance dust, we recommend the use of NIOSH approved respirators to protect against silicosis reproducing dusts. Special Considerations for Repair/Maintenance of Contaminated Equipment: Ensure proper respiratory protection Spill or Leak Procedures Procedures for Spill/Leak: Vacuum clean or wet sweep, avoid dusting, and use a dust suppressant when sweeping. Waste Management: Not considered as hazardous wastes by RCRA (40 CFR part 261). Place waste and spillage in closed containers. Dispose of in approved landfill: RQ-N/A Health Hazards Summary/Risks: This product may contain crystalline silica (less than 0. 1% - see section II). OSHA considers Perlite a nuisance dust and recommends a PEL of 5 mg/m3 TWA respirable dust. Inhalation over long periods of high amounts of any nuisance dust may overload lung clearance mechanism and make the lungs more vulnerable to respiratory disease. Medical Conditions Which May Be Aggravated: Pre-existing upper respiratory and lung disease (such as bronchitis, emphysema, asthma, or others). Target Organ(s): Lungs Acute Health Effects: Transitory upper respiratory irritant. Primary Entry Route(s): Inhalation Chronic Health Effects: See summary. Follow the safe handling practices shown on the product bag label. Sign/Symptoms of Overexposure: This product may contain crystalline silica (less than 0. 1% - see section II). OSHA considers Perlite a nuisance dust and recommends a PEL of 5 mg/m3 TWA respirable dust. Inhalation over long periods of high amounts of any nuisance dust may overload lung clearance mechanism and make the lungs more vulnerable to respiratory disease. Inhalation: Coughing, irritation of nose and throat; congestion may occur upon over exposure. Skin Contact: N/A Skin Absorption: N/A Eyes: Temporary irritation and/or inflammation Ingestion: Not hazardous. Generally regarded as safe by the FDA First Aid/Emergency Procedure: Inhalation: Exit from dust area; drink water to clear throat; blow nose to evacuate dust. Skin Contact: N/A Skin Absorption: N/A Ingestion: None Eyes: Do not rub eyes. Flush eyes with copious amounts of water to remove any dust particles. Contact a physician if irritation persists. Reactivity Data Stability: Material is stable. Hazardous polymerization will not occur. Chemical Incompatibilities: Hydrofluoric Acid Conditions to Avoid: None in designed use. Avoid contact with hydrofluoric acid. Hazardous Decomposition Products: Reacts with hydrofluoric acid to form toxic silicon tetraflouride gas. Specials Precautions Storage Segregation Hazard Classes: N/A ****Always segregate materials by major hazard class**** Special Handling/Storage: Store in dry place. Repair all broken bags immediately. Avoid creating dust. Maintain good housekeeping practice. Special Workplace Engineering Controls: Adequate ventilation and appropriate local exhaust where needed to keep dust levels below PEL. Other: Comply with all Federal, State and Local regulations.
