Inhalation:

First aid is generally not required. If dust is inhaled, remove to fresh air and keep in a rest position comfortable for breathing. If difficulty in breathing persists seek medical attention. At high concentrations: can irritate the nose and throat.

Skin Contact:

Broken edges of finished product may be sharp causing laceration to skin, if needed seek medical attention.

Eye Contact: If broken/chipped piece of slab or dusts get into eye(s), immediately rinse with plenty of water. Do not rub eyes. If eye irritation persists, get medical advice and attention.

Ingestion: Not applicable under normal handling conditions. If large amounts of dusts are ingested rinse mouth. Do not induce vomiting. Seek medical attention.

Most Important Symptoms and Effects (acute or delayed/chronic)

Acute:

Inhalation: Nasal congestion. Sneezing, coughing, sore throat, wheezing and shortness of breath. Skin: Dust can cause mechanical abrasion, redness, rash like appearance, discomfort. Sharp edges can cut skin Eyes: Redness, discomfort, pain.

Delayed/Chronic:

Repeat or prolonged inhalation of crystalline silica above specified concentrations may cause lung cancer or silicosis.

ADVICE FOR FIRE FIGHTERS

Precautionary Measures Fire: Fight fire with normal precautions from a reasonable distance Firefighting Instructions: Keep a distance and upwind of fire

Protection During Firefighting: Use self-contained breathing apparatus and individual fire protective equipment.

Use of Personal Precautions:

Wear appropriate protective clothing and equipment where risk of exposure to dust is present. Wear cut resistant gloves where sharp edges are present.

Environmental Precautions:

No specific precautions required. Report any releases in accordance with local, state/provincial, or federal regulations.

Methods for Containment/Cleaning-Up:

Solid slab material can be gathered and disposed of. Avoid generating dust. Dust may be cleaned using HEPA filtered vacuum or shovel/sweep after light wetting down to avoid generating airborne particles. Do not dry sweep. Dispose of dust in closed containers.

No toxicological data is available for this product in solid form. No adverse health effects expected if the product is handled in accordance with this Safety Data Sheet.

The following applies if the product is cut, drilled, grinded or polished and risk of inhalation of respirable crystalline silica dust is present if proper controls are not adhered to, the following symptoms or effects could occur from respirable crystalline silica/quartz (inhalation) exposure in excess of the permissible limits:

CANCER: Crystalline silica (respirable size) has been classified by: The International Agency for Research on Cancer (IARC): Group 1 Carcinogen to humans The American Conference of Governmental Industrial Hygienists (ACGIH): Suspected human carcinogen with an A2 classification. National Toxicology Program (NTP) carcinogenic classification: Known human carcinogen.

SILICOSIS: Prolonged inhalation of respirable dust containing crystalline silica may result in silicosis, a disease characterized by inflammation and progressive fibrosis of the lungs. Also known as pneumoconiosis (lung disease caused by the inhalation of dust), silicosis is marked by shortness of breath and impaired lung function which may give rise to complications that can result in death. The development and the severity of silicosis depends on the airborne concentration of silica dust to which a worker is exposed and the duration of exposure. Crystalline silica may be harmful following high exposure levels received over a period, ranging from a few weeks to years or after long-term exposures to lower levels. There are three major types of silicosis:

Acute Silicosis: Can occur after repeated inhalation of very high concentrations of respirable crystalline silica over a short period of time. As few as 8 to 18 months may elapse from the time of first exposure to the onset of symptoms. Symptoms include a more rapid onset of progressive shortness of breath, cough, weakness, fever, and weight loss. There is a rapid progression of respiratory failure usually resulting in death within one or two years.

Chronic Silicosis: The most common type of silicosis and occurs after many years (usually more than 10 years) after contact with prolonged and repeated exposure to low concentrations of inhaled crystalline silica. Symptoms progress and worsen over a period of many years. The effects of chronic silicosis can continue to develop even after the exposure ceases, the effects are irreversible. Chronic silicosis may be either a simple or a complicated type:

Simple Chronic Silicosis: Almost entirely without symptoms. In the early stages, the lung nodules are small (usually 1 to 3 mm) and discrete in the upper lung fields. As the disease progresses the nodules increase in number and size and also occupy the lower field. Although simple silicosis may never grow more serious, long-term exposure to silica dust may lead to complicated silicosis.

Complicated Chronic Silicosis: Also called progressive massive fibrosis (PMF). First symptoms may include shortness of breath with exercise, wheezing or sputum that causes coughing. Some people with the disease has no symptoms; may become worse when in combination with other lung diseases. Severe complicated silicosis can result in heart disease in addition to lung disease.

Accelerated Silicosis: Similar to the chronic type, but develops more quickly with the lung scars appearing sooner. Nodules may appear sooner on a chest x-ray five years after the first exposure to silica dust. This type of silicosis occurs from exposure to large amounts of silica dust over a short time period and can progress quickly.

Non-Malignant Respiratory Diseases: There is concern that there is an association between exposure to respirable crystalline silica and chronic bronchitis, emphysema and small airway disease.

Aggravation of Pre-Existing Conditions: Inhalation of dusts may aggravate pre-existing respiratory conditions. Smoking and exposure to respirable crystalline silica increases the risks of lung damage.

Carcinogenicity: CARCINOGEN. Known to cause: lung cancer.

• International Agency for Research on Cancer (IARC): Group 1 - Carcinogenic to humans.

• American Conference for Governmental Industrial Hygienists (ACGIH): A2 - Suspected human carcinogen.

Teratogenicity / Embryotoxicity: Not known to harm the unborn child.

Reproductive Toxicity: Not known to be a reproductive hazard.

Mutagenicity: Conclusions cannot be drawn from the limited studies available.
