Supplemental information:
Respirable Crystalline Silica (RCS) may cause cancer. Marble is a naturally occurring mineral complex that contains
varying quantities of quartz (crystalline silica). Marble may be subjected to various natural or mechanical forces that
produce small particles (dust) which may contain respirable crystalline silica (particles less than 10 micrometers in
aerodynamic diameter). Repeated inhalation of respirable crystalline silica (quartz) may cause lung cancer according to
IARC, NTP; ACGIH states that it is a suspected cause of cancer. Other forms of RCS (e.g., tridymite and cristobalite) may
also be present or formed under certain industrial processes.

4. First-aid measures
Inhalation:
Remove to fresh air. Dust in throat and nasal passages should clear spontaneously. Contact a physician if irritation
persists or if breathing is difficult.
Eyes:
Immediately flush eye(s) with plenty of clean water for at least 15 minutes, while holding the eyelid(s) open.
Occasionally lift the eyelid(s) to ensure thorough rinsing. Beyond flushing, do not attempt to remove material from
eye(s). Contact a physician if irritation persists or later develops.
Skin:
Wash affected areas thoroughly with mild soap and fresh water. Contact a physician if irritation persists.
Ingestion:
If person is conscious do not induce vomiting. Give large quantity of water and get medical attention. Never attempt to
make an unconscious person drink.
Most important symptoms/effects, acute and delayed:
Dust may irritate the eyes, skin, and respiratory tract. Breathing silica-containing dust for prolonged periods in the
workplace can cause lung damage and a lung disease called silicosis. Symptoms of silicosis may include (but are not
limited to) shortness of breath, difficulty breathing with or without exertion; coughing; diminished work capacity;
diminished chest expansion; reduction of lung volume; right heart enlargement and/or failure.
Indication of immediate medical attention and special treatment needed:
Not all individuals with silicosis will exhibit symptoms of the disease. However, silicosis can be progressive, and
symptoms can appear at any time, even years after exposures have ceased. Persons with silicosis have an increased risk
of pulmonary tuberculosis infection.

5. Fire-fighting measures
Suitable extinguishing media:
This product is not flammable. Use fire-extinguishing media appropriate for surrounding materials.
Unsuitable extinguishing media:
None known.
Specific hazards arising from the chemical:
Contact with powerful oxidizing agents may cause fire and/or explosions (see section 10 of SDS).
Special protective equipment and precautions for firefighters:
Use protective equipment appropriate for surrounding materials.
Fire-fighting equipment/instructions:
No unusual fire or explosion hazards noted. Not a combustible dust.
Specific methods:
The presence of this material in a fire does not hinder the use of any standard extinguishing medium. Use extinguishing
medium for surrounding fire.
