7. HANDLING AND STORAGE
7.1 Precautions for safe Handling
Do not breathe dust. Obtain special instructions before use. Do not handle until all safety instructions have been read and understood. Wear eye and respiratory protection. Avoid airborne dust generation.
Use appropriate exhaust ventilation at places where airborne dust is generated, including during loading and unloading. Do not rely on your sight to determine if dust is in the air. Respirable crystalline silica dust may be invisible in the air. Handle packaged products carefully to prevent accidental bursting. Maintain and test ventilation and dust collection equipment. Use available work practices to control dust exposures, such as water sprays. Practice good housekeeping. Do not permit dust to collect on walls, floors, sills, ledges, machinery, or equipment. Exposures to respirable crystalline silica can occur when cutting, sawing, grinding, drilling, and crushing this material or articles that contain this material.
7.2 Conditions for safe storage
Keep containers closed and store to avoid accident altering, breaking, or bursting. Inert and unreactive with most chemicals. Contact with powerful oxidizing agents such as fluorine, chlorine trifluoride, and oxygen difluoride may cause fires.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
8.1 Exposure limits
OSHA PEL 8-hour time-weighted average for respirable quartz expressed as millions of particles per cubic foot of air, based on impinger samples counted by light-field techniques:
250
(%SiO2+5)
The percentage of crystalline silica in the formula is the amount determined from airborne samples, except in those instances in which other methods have been shown to be applicable. OSHA PEL 8-hour time weighted average for respirable quartz expressed as milligrams per cubic meter:
10 mg/m3
(%SiO2+2)
Both concentration and percent quartz for the application of this limit is to be determined from the fraction passing a size-selector with the following characteristics:
| Aerodynamic Diameter(Unit density sphere) | Percent Passing Selector |
| 2 | 90 |
| 2.5 | 75 |
| 3.5 | 50 |
| 5 | 25 |
| 10 | 0 |
r 30 mg/m3
(%SiO2+2)
On September 12, 2013, OSHA published a preliminary quantitative risk assessment concluding that the available evidence indicates that employees exposed to respirable crystalline silica well below the current PELs are at increased risk of lung cancer mortality and silicosis.
CAL OSHA PEL 8-hour time-weighted average for respirable quartz 0.1 mg/m3
CAL OSHA PEL 8-hour time-weighted average for quartz total dust 0.3 mg/m3
ACGIH TLV 8-hour time-weighted average for respirable α-quartz and cristobalite 0.025mg/m3
NIOSH REL up to 10-hour time-weighted average for respirable quartz ca 0.05 mg/m3
8.2 Appropriate Engineering Controls
Avoid airborne dust generation. Use process enclosures and appropriate exhaust ventilation at places where airborne dust is generated, including during loading and unloading. Apply organizational measures, e.g. by isolating personnel from dusty areas. Remove and wash soiled clothing.
8.3 Individual protection measures, such as personal protective equipment
8.3.1 Eye/Face Protection
Wear appropriate safety glasses with side shields or chemical goggles.
8.3.2 Skin Protection
Wear body-covering clothing. Appropriate hand protection (e.g. gloves, barrier cream) is recommended for workers who suffer from dermatitis or sensitive skin. Wash hands at the end of each work session. Remove and wash soiled clothing.
8.3.3 Respiratory ProtectionWhen engineering and work practice controls are not feasible, while they are being implemented, or when they do not reduce silica levels below OSHA PELs, employers must provide workers with respirators. Whenever respirators are used, the employer must have a respiratory protection program that meets the requirements of OSHA’s Respiratory Protection standard (29 CFR 1910.134). This program must include proper respirator selection, fit testing, medical evaluations, and training. See, OSHA’s Respiratory Protection eTool, available at www.osha.gov/SLTC/etools/respiratory/index.html

11.TOXICOLOGICAL INFORMATION
11.1 Likely routes of exposure
The relevant route for occupational exposure is by inhalation.
11.2 Symptoms related to the physical, chemical and toxicological characteristics
Dry chronic cough, sputum production, shortness of breath, wheezing, and reduced pulmonary function.
11.3 Delayed and immediate effects and also chronic effects from short-and long-term exposure
11.3.1 Short-term exposure
Acute silicosis can occur within a few weeks to months after inhalation exposure to extremely high levels of respirable crystalline silica. Acute silicosis causes decreased lung function and can result in heart disease secondary to lung disease: heart failure and cor pulmonary. Death from acute silicosis can occur within months to a few years of disease onset, and persons with acute silicosis are at high risk of contracting other lung diseases including tuberculosis, atypical mycobacterial infections, and fungal superinfections. Quantitative information on the level of exposure that causes acute silicosis is not available, but available information indicates those levels are far in excess of permissible exposure limits. Animal studies also suggest that pulmonary reactions of rats to short-duration exposure to freshly fractured silica mimic those seen in acute silicosis in humans.
Accelerated silicosis results from exposure to high levels of airborne respirable crystalline silica, and usually occurs within 2 to 10 years of initial exposure. Accelerated silicosis causes decreased lung function and can result in heart disease secondary to lung disease. Accelerated silicosis has a rapid, severe course and persons with this condition are at high risk of contracting other lung diseases including tuberculosis, atypical mycobacterial infections, fungal superinfections, and lung cancer. Quantitative information on the level of exposure that causes accelerated silicosis is not available, but available information indicates those levels are substantially in excess of permissible exposure limits.
11.3.2 Long term exposure
Chronic silicosis generally occurs after 10 years or more of inhalation exposure to respirable crystalline silica at levels below those associated with acute and accelerated silicosis. Chronic silicosis in most cases is a slowly progressive disease resulting in decreased lung function and can result in heart disease secondary to lung disease. Its effects are disabling and may lead to death. Persons with chronic silicosis are at high risk of contracting other lung diseases including tuberculosis, atypical mycobacterial infections, fungal superinfections, and lung cancer. On September 12, 2013, OSHA published a preliminary quantitative risk assessment concluding that the available evidence indicates that employees exposed to respirable crystalline silica well below the current PELs are at increased risk of lung cancer mortality and silicosis.
Chronic obstructive pulmonary disease, COPD, including chronic bronchitis and emphysema, occurs in silica-exposed workers, including those who do not develop silicosis. Respirable crystalline silica exposure and smoking may be synergistic for COPD, that is, there is evidence that the combined effect of exposure to respirable crystalline silica and smoking may be greater than additive.
Respirable crystalline silica is recognized by OSHA, NTP, and IARC as a cause of lung cancer. Respirable crystalline silica is an independent risk factor from smoking for lung cancer. Respirable crystalline silica exposure and smoking may be synergistic for lung cancer, that is, there is some evidence that the combined effect of exposure to respirable crystalline silica and smoking may be greater than additive.
There is substantial evidence suggesting an association between exposure to inhaled respirable crystalline silica and increased risks of renal (kidney) and systemic autoimmune disease (scleroderma, rheumatoid arthritis, and systemic lupus erythematosus).
11.4 Numerical measures of toxicity (such as acute toxicity estimates)
Crystalline silica is not acutely toxic. Reliable numerical measures of chronic toxicity do not exist.
12. ECOLOGICAL INFORMATION
