SAFETY DATA SHEET (SDS) 

Engineered Quartz Slabs (Approx. 91% Crystalline Silica) 

 

1. Identification 

Product Name: Engineered Quartz Slabs 

Recommended Use: Countertops, wall cladding, interior surfaces 

Supplier: Multiple 

Address: Phoenix, Arizona, USA 

Emergency Contact:  480-613-7487

 

2. Hazard Identification 

Classification (OSHA GHS): 

  • Carcinogenicity – Category 1A 

  • Specific Target Organ Toxicity (Repeated Exposure) – Category 1 

  • Skin Abrasion Hazard (mechanical) 

CRITICAL FABRICATOR WARNING: 

This product contains approximately 87%-91% crystalline silica. Processing activities, including but not limited to cutting, grinding, drilling, polishing, routing, or dry sweeping WILL generate respirable crystalline silica dust. Exposure to respirable crystalline silica can cause silicosis, lung cancer, chronic obstructive pulmonary disease (COPD), and kidney disease. These hazards are well-documented and can result in permanent disability or death. 

Hazard Statements: 

  • May cause cancer by inhalation of respirable crystalline silica dust 

  • Causes damage to lungs through prolonged or repeated exposure 

  • Dust generated during fabrication is hazardous and must be controlled 

Fabricator Responsibility Notice: 

  • Fabricators, installers, and processors assume full responsibility for implementing OSHA-compliant safety controls 

  • Failure to use proper controls may result in serious injury or death 

  • Employers must comply with OSHA Respirable Crystalline Silica Standard (29 CFR 1926.1153) 

Precautionary Statements: 

  • Do not breathe dust 

  • Use only with adequate ventilation and dust suppression 

  • ALWAYS use wet cutting methods 

  • NEVER dry cut, grind, or polish 

  • Use HEPA-filtered dust extraction systems 

  • Wear appropriate respiratory protection (minimum NIOSH-approved P100 or supplied air when required) 

 

3. Composition / Information on Ingredients 

  • Crystalline Silica (Quartz): 87%-91% 

  • Polymer resins: 6–8% 

  • Pigments and additives: 1–3% 

 

4. First Aid Measures 

Inhalation: Move to fresh air. Seek medical attention if symptoms persist. 

Skin Contact: Wash with soap and water. 

Eye Contact: Rinse cautiously with water for several minutes. 

Ingestion: Not expected route of exposure. 

 

5. Fire-Fighting Measures 

  • Suitable extinguishing media: Water spray, foam, dry chemical 

  • Hazards: Resin components may emit toxic fumes when burned 

 

6. Accidental Release Measures 

  • No special cleanup required for solid slabs 

  • Avoid generating dust during cleanup 

 

7. Handling and Storage 

Handling (MANDATORY FABRICATOR CONTROLS): 

  • Dry cutting, grinding, or polishing is strictly prohibited 

  • Use wet cutting methods at all times to suppress dust 

  • Utilize local exhaust ventilation with HEPA filtration 

  • Implement OSHA-compliant exposure control plans 

  • Conduct air monitoring where required 

  • Provide worker training on silica hazards 

Safe Work Practices: 

  • Do not use compressed air or dry sweeping to clean dust 

  • Use HEPA vacuums or wet cleanup methods 

  • Isolate fabrication areas to prevent dust migration 

Storage: 

  • Store in dry area 

  • Secure slabs to prevent tipping hazards 

 

8. Exposure Controls / Personal Protection 

Exposure Limits: 

  • OSHA PEL (Respirable Crystalline Silica): 50 µg/m³ (8-hour TWA) 

Engineering Controls (REQUIRED): 

  • Wet cutting and polishing systems 

  • Local exhaust ventilation with HEPA filtration 

  • Enclosed or isolated fabrication areas, where feasible 

Personal Protective Equipment (PPE): 

  • Respiratory Protection: NIOSH-approved respirator (minimum P100). Supplied-air respirators may be required for high-exposure tasks 

  • Eye Protection: Safety glasses or goggles 

  • Skin Protection: Cut-resistant gloves 

Employer Responsibilities: 

  • Implement a written exposure control plan 

  • Provide medical surveillance where required 

  • Ensure proper respirator fit testing and training 

 

9. Physical and Chemical Properties 

  • Appearance: Solid slab 

  • Odor: None 

  • Solubility: Insoluble 

  • Density: ~2.3–2.5 g/cm³ 

 

10. Stability and Reactivity 

  • Stable under normal conditions 

  • Avoid dust generation 

 

11. Toxicological Information 

Primary Hazard: Respirable crystalline silica dust generated during fabrication 

Health Effects: 

  • Silicosis (progressive, irreversible lung disease) 

  • Lung cancer (classified as carcinogenic to humans) 

  • Chronic obstructive pulmonary disease (COPD) 

  • Kidney disease 

Important Fabricator Warning: 

Repeated or uncontrolled exposure to respirable silica dust has resulted in severe illness and death in fabrication workers. Risk is significantly increased when proper controls are not used. 

 

12. Ecological Information 

  • No significant environmental impact expected 

 

13. Disposal Considerations 

  • Dispose in accordance with local regulations 

 

14. Transport Information 

  • Not regulated as hazardous material 

 

15. Regulatory Information 

  • OSHA Hazard Communication Standard (29 CFR 1910.1200) 

  • California Proposition 65 (crystalline silica) 

 

16. Other Information 

Fabrication Hazard Disclaimer: 

Marbino Surfaces supplies this product as a finished solid material. Hazards associated with respirable crystalline silica arise ONLY when the product is mechanically altered (cut, ground, drilled, or polished). It is the sole responsibility of the fabricator, installer, or employer to: 

  • Assess workplace hazards 

  • Implement required engineering controls 

  • Ensure compliance with all applicable OSHA regulations 

Marbino Surfaces assumes no responsibility for injuries, illnesses, or damages resulting from failure to follow proper safety procedures during fabrication or installation.
