Personal Precautions, Protective Equipment, and Emergency Procedures: Wear appropriate respiratory and protective equipment specified in section 8. Isolate spill area and provide ventilation. Avoid breathing dust or fume. Avoid contact with skin and eyes.

Methods and Materials for Containment and Cleaning Up: Avoid raising dust. Scoop or vacuum up using a vacuum system equipped with a HEPA filter. Place in properly labeled closed containers.

Environmental Precautions: Do not allow to enter drains or to be released to the environment.

 

 

7   HANDLING AND STORAGE

Precautions for Safe Handling: Handle in an enclosed, controlled process. Avoid creating dust. Avoid breathing dust or fumes. Provide adequate ventilation if dusts are created. Avoid contact with skin and eyes. Wash thoroughly before eating or smoking. See section 8 for information on personal protection equipment.

Conditions for Safe Storage: Store in a cool, dry, well-ventilated area. Store in a tightly sealed container. See section 10 for more information on incompatible materials.

 

 

8   EXPOSURE CONTROLS AND PERSONAL PROTECTION

Exposure Limits:                      OSHA/PEL:                                 ACGIH/TLV:

Silicon Dioxide, amorphous          No exposure limit established       No exposure limit established

Quartz (respirable)                      10 mg/m3                                  ---

Silica, crystalline (respirable)        ---                                             0.025 mg/m3 (for α-quartz and crystobalite)

Engineering Controls: Handle in a controlled, enclosed environment. Ensure adequate ventilation to maintain exposures below occupational limits. Whenever possible the use of local exhaust ventilation or other engineering controls is the preferred method of controlling exposure to airborne dust and fume to meet established occupational exposure limits. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating or smoking. Do not blow dust off clothing or skin with compressed air.

Individual Protection Measures, Such as Personal Protective Equipment:

Respiratory Protection: Avoid inhaling dusts. Use suitable respirator if dusts are present.

Eye Protection: Safety glasses

Skin Protection: Impermeable gloves, protective work clothing as necessary.

11   TOXICOLOGICAL INFORMATION

Likely Routes of Exposure: Inhalation, skin and eyes.

Symptoms of Exposure: May cause irritation if dusts or fumes are inhaled or swallowed. Dusts may irritate skin and eyes.

Acute and Chronic Effects: Silicon dioxide is chemically and biologically inert when ingested. Heavy exposure to freshly formed silica fume may cause an acute reaction similar to metal fume fever. Respirable quartz dust particles can be inhaled and deposited in the lung. Silicosis, lung cancer and pulmonary tuberculosis are associated with occupational exposure to quartz dust. There is sufficient evidence in humans for the carcinogenicity of inhaled crystalline silica in the form of quartz or cristobalite dusts from occupational sources. Because amorphous silica is less fibrogenic than crystalline silica, silicosis has rarely been observed after exposure to pure amorphous silica.

Acute Toxicity: No data

Carcinogenicity: (Note: the material as supplied may be crystalline or amorphous. Carcinogenicity is assigned to respirable dusts of crystalline silica only)

NTP: Silica, crystalline (respirable size): K - Known to be carcinogenic

IARC: Silica, amorphous: 3 - Not classifiable as to its carcinogenicity to humans

IARC: Silica, dust, crystalline, in the form of quartz or cristobalite: 1 - Carcinogenic to humans

16   OTHER INFORMATION

Silicosis is a lung disease caused by breathing in crystalline silica dust. Crystalline silica is a basic component of soil, sand, granite, and most other types of rock. Silicosis mostly affects workers exposed to silica dust in occupations such as mining, glass manufacturing, sand-blasting, and foundry work. Over time, inhalation of silica dust particles can cause inflammation, fluid buildup and scarring in the lungs. The symptoms of silicosis usually take many years to develop and include cough, weight loss, and fatigue. Silicosis can also increase the risk of other serious and potentially life-threatening conditions, including chronic obstructive pulmonary disease (COPD) and lung cancer. Even though the risks associated with crystalline silica (silicon dioxide) are mainly from long-term exposure to dusts in industrial settings, it seems prudent to take all precautions against breathing any silicon dioxide dusts.
