MSDS

Keep away from heat. Wash thoroughly after handling. Do not smoke. Intentional misuse by deliberately concentrating
and inhaling vapors may be harmful or fatal.
Construction and repair activities can adversely affect indoor air quality. Consult with occupants or a representative (i.e.
maintenance, building manager, industrial hygienist, or safety officer) to determine ways to minimize impact.
Storage: Store away from sources of ignition and heat. Keep away from heat and sources of ignition. Keep containers
tightly closed. Do not store at temperatures above 120 degrees F. Store containers away from excessive heat and
freezing. Store away from caustics and oxidizers.
Important: Listed Permissible Exposure Levels (PEL) are from the U.S. Dept. of Labor OSHA Final Rule Limits (CFR 29 1910.1000); these limits may vary
between states.
Note: An employee's skin exposure to substances having a "YES" in the "SKIN" column in the table above shall be prevented or reduced to the extent
necessary under the circumstances through the use of gloves, coveralls, goggles or other appropriate personal protective equipment, engineering controls or work
practices.
Exposure Notes:
14808-60-7 The 2002 ACGIH Threshold Limit Values for Chemical Substances and Physical Agents lists the median
Respirable Particulate Mass (RPM) point for crystalline silica at 4.0 microns in terms of the particle's aerodynamic
diameter.
The TLVs for crystalline silica represent the respirable fraction.
OSHA PEL TWA for Quartz is calculated using the following formula: 10 mg/m3/(% SiO2 + 2). Both concentration and
percent quartz for the application of this limit are 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...................|
| 5.0 .............................................................................|..................25...................|
| 10 ..............................................................................|...................0....................|
Precautionary Measures: Please refer to other sections and subsections of this MSDS.
Engineering Controls: Use only in well-ventilated areas. Vapors are heavier than air and may spread along floors.
Check all low areas for presence of vapor. Provide sufficient general and/or local exhaust ventilation to maintain exposure
below recommended exposure limit. The following exposure control techniques may be used to effectively minimize
employee exposure: local exhaust ventilation, enclosed system design, process isolation and remote control in
combination with appropriate use of personal protective equipment and prudent work practices. These techniques may
not necessarily address all issues pertaining to your operations. We, therefore, recommend that you consult with experts
of your choice to determine whether or not your programs are adequate.
If airborne contaminants are generated when the material is heated or handled, sufficient ventilation in volume and air flow
patterns should be provided to keep air contaminant concentration levels below acceptable criteria.
Ensure fresh air entry during application and drying. If you experience eye watering, headache or dizziness or if air
monitoring demonstrates vapor/mist levels are above applicable limits, wear an appropriate, properly fitted respirator
(NIOSH approved) during and after application. Follow respirator manufacturer's directions for respirator use.
Respiratory Protection: In case of insufficient ventilation, wear suitable respiratory equipment. If concentrations exceed
