- Environmental precautions
- No special environmental precautions required.
- Cleaning / absorption
- Prevent further leakage or spillage if safe to do so. Avoid generating dust. Collect using an appropriate dustless method. Dispose in landfill according to local, state and federal regulations.
7. Handling and Storage
- Precautions for safe handling
- This product contains quartz which may become airborne. Avoid breathing dust and creating dusty conditions. Promptly clean up spills. Use only with adequate ventilation to keep exposure below recommended limits. Wear a NIOSH/MSHA (or European Standard EN 149, or equivalent) respirator certified for silica-bearing dust. Material is slippery when wet.
- Conditions for safe storage
- Use good housekeeping to prevent dust accumulation. Close container when not in use. Do not reuse empty container. Do not allow water/moisture to contact the product until time of use, to preserve product utility.
8. Exposure Controls / Personal Protection
| Substance | CAS number | ACGIH TLV-TWA | OSHA PEL-TWA* |
|---|---|---|---|
| Crystalline silica, quartz | 14808-60-7 | 0.025 mg/m³ | 10 mg/m³ ÷ (%SiO₂ + 2) |
* More restrictive exposure limits may be enforced by some states, agencies, or other authorities.
- Engineering controls
- Use approved industrial ventilation and local exhaust as required to maintain exposures below applicable limits.
- Respiratory protection
- Not normally needed. If significant exposures exceeding the occupational exposure limit are possible, use a NIOSH/MSHA respirator approved for silica-bearing dust.
- Hand protection
- Standard work gloves.
- Skin protection
- Wear clothing appropriate for the work environment. Launder dusty clothing before reuse; avoid creating dust when removing or laundering clothing.
- Eye protection
- Wear safety glasses or goggles to protect against exposure.

11. Toxicological Information
- Principal route of exposure
- Eye or skin contact, inhalation.
- Inhalation
- Inhaled crystalline silica in the form of quartz from occupational sources is carcinogenic to humans (IARC, Group 1).
- Skin contact
- May cause skin irritation due to drying.
- Eye contact
- May cause mechanical eye irritation.
- Aggravated medical conditions
- Individuals with respiratory disease (including but not limited to asthma and bronchitis) or subject to eye irritation should not be exposed to respirable quartz-bearing dust.
Chronic effects and carcinogenicity
Silicosis: Excessive inhalation of respirable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lung disease called silicosis (symptoms include cough, shortness of breath, wheezing, non-specific chest illness, and reduced pulmonary function), exacerbated by smoking; individuals with silicosis are predisposed to develop tuberculosis.
Cancer status: IARC (1997) concludes there is sufficient evidence in humans for carcinogenicity of inhaled crystalline silica from occupational sources (Group 1). NTP classifies respirable crystalline silica as "Known to be a human carcinogen." ACGIH classifies crystalline silica, quartz, as a suspected human carcinogen (A2).
