At Eastern Construction Supplies, we are committed to transparency and customer safety.
Many of the stone and engineered quartz products we distribute contain crystalline silica, a naturally occurring mineral that, when inhaled in dust form, may cause serious long-term health problems such as silicosis, lung cancer, and other respiratory conditions.
⚠ Proposition 65 Warning
In accordance with California Proposition 65, we are required to inform users of the potential risks associated with crystalline silica.
⚠ WARNING: This product can expose you to crystalline silica, which is known to the State of California to cause cancer and birth defects or other reproductive harm.
Cutting, grinding, drilling, or polishing stone may release respirable crystalline silica dust into the air.
For more information, visit www.P65Warnings.ca.gov.
We include this warning:
- On our product pages
- On packing slips and invoices
- Directly labeled on the stone when applicable
🧰 Proper Use of Personal Protective Equipment (PPE)
Whether you’re a contractor, fabricator, or DIY installer, working safely with stone is essential.
Before performing any cutting, grinding, or polishing, please ensure the following:
✅ Use wet cutting tools and dust-suppression systems
✅ Wear a NIOSH-approved respirator (N95 or better)
✅ Use eye protection (goggles or safety glasses)
✅ Wear gloves and protective clothing
✅ Operate in a well-ventilated area or under exhaust ventilation systems
Never dry-cut engineered stone without full protective equipment and ventilation.
📌 We Do Not Provide Fabrication or Installation Services
Eastern Construction Supplies is a materials supplier only. We do not offer fabrication, installation, or on-site cutting services. However, we want all our customers and professional partners to stay informed and protected when handling any silica-based materials.
