* 2. Hazard(s) identification
Classification of the substance or mixture
There is no proof or indication that the whole, finished product [definable as an “article” according to both 29 CFR 1910.1200 (Hazard Communication Standard)] has any risks according to Globally Harmonized System (GHS).
In the case of the breakage of the article or its processing, involving cutting, shaping, engraving or any other process which could lead to the release of dust traceable to the matrix of the article, it may generate crystalline silica powder (SiO2) in the form of quartz . Generation and inhalation of this dust shall be avoided.
The hazard assessment refers to this specific case. No acute or chronic effects are known from exposure to intact slabs.
Please see Section 3 for the crystalline silica content of the whole finished product.Eye irritation 2A H319 Causes serious eye irritation. Carcinogenicity 1A H350 May cause cancer. Specific target organ toxicity (single exposure) 3 H335 May cause respiratory irritation. Specific target organ toxicity (repeated exposure) 1 H372 Causes damage to the lung through prolonged or repeated exposure. Route of exposure: Inhalation. Additional information:
The breathable fraction of crystalline silica (SiO2), particularly during prolonged exposures and/or exposures to high concentrations, may lead to lung damage or illnesses, such as silicosis.

Other hazards
If the product is processed in such a way that significant particulates and/or dusts may be generated, exposure may aggravate pre-existing eye, skin, or respiratory conditions. Machines and tools with water supply systems or the “wet method” must be used. Do not mechanically process the material using dry methods. Avoid generating airborne dust, especially without appropriate respiratory protective equipment, adequate air filtration and adequate air ventilation systems. Improper mechanical processing of this product may result in exposure to harmful silica dust (SiO2) inhalation, particularly if the recommended use of water, air filtration, and ventilation systems is not followed. When exposed to high temperatures, free quartz can change crystal structure to form tridymite (above 870°C.) or cristobalite (above 1470°C.) which have greater health hazards than quartz due to their more fibrogenic characteristics.
Manufacturers who crush, grind or cut ceramic bodies fired to high temperatures should recognize the possible presence of tridymite and/or cristobalite.
Slabs and boxes, if not grasped or handled correctly, can accidentally fall causing crushing of both hands and feet.Results of PBT and vPvB assessment
PBT: Not applicable.
vPvB: Not applicable.

* 4. First-aid measures
Description of first aid measures
General information:
First Aid Measures are applicable only to the dust resulting from crushing, grinding or sawing of slabs. Intact slabs pose no eye or inhalation hazards.After inhalation:
Supply fresh air. If required, provide artificial respiration. Keep patient warm. Consult doctor if symptoms persist. In case of unconsciousness place patient stably in side position for transportation.After skin contact:
Rinse opened eye for several minutes under running water. If symptoms persist, consult a doctor.After eye contact:
Rinse opened eye for several minutes under running water. If symptoms persist, consult a doctor.After swallowing:
Rinse out mouth with water. Do not induce vomiting.
Most important symptoms and effects, both acute and delayed
No acute effects are known from exposure to intact slabs. Working with broken or cut slab produces a potential for cuts to the hands and exposed body parts. Acute effects such as eye irritation may occur if associated with high dust operations such as dry cutting or drilling the slab or during the removal of slab surfaces. Symptoms of acute silicosis, a form of silicosis (a nodular pulmonary fibrosis) associated with exposure to respirable crystalline silica, may develop following acute exposure to extremely dusty environments caused by generation of slab dust. Signs such as labored breathing and early fatigue may indicate silicosis; however, these same symptoms can arise from many other causes.
No chronic effects are known from exposure to intact slabs. Long-term, continual exposure to respirable crystalline silica at or above allowable occupational exposure limits may lead to the development of silicosis, a nodular pulmonary fibrosis (NPF). NPFs are also associated with pulmonary tuberculosis, bronchitis, emphysema, and other airway diseases. This type of chronic exposure to silica dust may also result in the development of autoimmune disorders, chronic renal disease, and other adverse health effects. Recent epidemiologic studies demonstrate that workers exposed to elevated silica concentrations have a significant risk of developing chronic silicosis. Signs such as labored breathing and early fatigue may indicate silicosis.

Information on toxicological effects
Potential Health Effects: none for intact slab.
Acute toxicity:
LD/LC50 values that are relevant for classification:
CAS: 14808-60-7 Quartz (SiO2) Oral LD50 >2,000 mg/kg (rat) Dermal LD50 >2,000 mg/kg (rabbit) Inhalative LC50 / 4h No specific data are available on acute toxicity that would permit a 100% categorical decision on the classification for acute toxicity by inhalation for any kind of crystalline silica. As a result, animal welfare concerns make further experiments unjustifiable. Primary irritant effect:
Symptoms/Injuries After Inhalation: for particulates or dust from processing: irritation of the respiratory tract and the other mucous membranes. Cough, dyspnea (breathing difficulty), wheezing; decreased pulmonary function, progressive respiratory symptoms (silicosis). The lungs become very inflamed and may fill with fluid, causing severe shortness of breath and low blood oxygen levels.on the skin:
Symptoms/Injuries After Skin Contact: for particulates or dust from processing: prolonged exposure may cause skin irritation. Direct contact may cause irritation by mechanical abrasion.on the eye:
Symptoms/Injuries After Eye Contact: for particulates or dust from processing: may cause slight irritation to eyes. Contact may cause irritation due to mechanical abrasion.
Carcinogenicity:
Respirable Crystalline Silica (RCS)
Respirable crystalline silica is classified by the International Agency for Research on Cancer (IARC) as a Group I Carcinogen (carcinogenic to humans). The National Toxicology Program lists respirable crystalline silica as “Known to be a Human Carcinogen”. USDOL/OSHA and NIOSH regulated crystalline silica as carcinogenic.Additional toxicological information:
Prolonged exposure to respirable crystalline quartz may cause delayed (chronic) lung injury - silicosis. Acute or rapidly developing silicosis may occur in a short period of time in heavy exposure. Silicosis is a form of disabling pulmonary fibrosis which can be progressive and may lead to death.
Some studies show that exposure to respirable crystalline silica (without silicosis) or that the disease silicosis may be associated with the increased incidence of several autoimmune disorders such as scleroderma (thickening of the skin), systemic lupus erythematosus, rheumatoid arthritis and diseases affecting the kidneys. Silicosis increases the risk of tuberculosis. Some studies show an increased incidence of chronic kidney disease and end-stage renal disease in workers exposed to respirable crystalline silicaCarcinogenic categories
