Natural Stone Products (Tiles, Trim, Decoration)

SECTION 2: Hazards identification

OSHA CARCINOGEN IRRITANT / REPIRATORY TRACT IRRITATION NOTES: Not applicable for intact stone products. Excessive exposure to dust can cause discomfort and mechanical irritation. Long term exposure to silica dusts can lead to silicosis. EMERGENCY OVERVIEW: OSHA LISTS THESE AS CATEGORY “B” STONES (CONTAINING LESS THAN 1% CRYSTALLINE SILICA), CONSIDRED TO BE A NUISANCE PARTICULATE FROM DUST THAT CAN ACCUMULATE IN THE LUNGS. AVOID DUST PRODUCTION BY CUTTING UNDER WATER, AND USE PROTECTIVE BREATHING APPARATUS AND EYE PROTECTION, AS OUTLINED IN SECTION 8.

Potential health effects

EYES: Mechanical stress through eye rubbing if exposed to dust or airborne particulates SKIN: Skin irritation if exposed to dust or airborne particulates INGESTION: Potential choking hazard if exposed to airborne particulates INHALATION: Mechanical stress from inhalation of dust or airborne particulates

(R) Respirable (T) Total § Crystalline silica is normally measured as respirable dust. The OSHA standard also presents a formula for calculation of the PEL based on total dust 30 mg/m3 / (% SiO2 + 2). # Particulate matter containing no asbestos and <1% crystalline silica.
