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: Contact lenses pose a special hazard; soft lenses may absorb and all lenses concentrate
irritants.
Engineering Controls: Good general ventilation should be sufficient to control airborne levels. Ensure adequate
ventilation, especially in confined areas. Local ventilation of emission sources may be necessary to maintain ambient
concentrations below recommended exposure limits.
Respiratory Protection: In case of insufficient ventilation, wear suitable respiratory equipment. A NIOSH-approved air
purifying respirator with an organic vapor cartridge or canister may be necessary under certain circumstances where
airborne concentrations are expected to exceed exposure limits. A respiratory protection program that meets the OSHA
1910.134 and ANSI Z88.2 requirements must be followed whenever workplace conditions warrant a respirator's use.
National Institute for Occupational Safety and Health (NIOSH) has recommended that the permissible exposure limit be
changed to 50 micrograms respirable free silica per cubic meter of air (0.05 mg/m3) as determined by a full shift sample
up to 10-hour work shift.
Skin Protection: Rubber gloves. Natural rubber, butyl rubber and polyvinyl chloride gloves are not suitable protection
against the phthalates contained within this product; neoprene is recommended.
Eye Protection: Goggles or safety glasses with side shields.
Other protective equipment: Not required under normal use.
Hygienic Practices: Wash hands before breaks and at the end of workday. Remove and wash contaminated clothing
before re-use.
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.
When reported, vapor pressure of this product has been calculated theoretically based on its constituent makeup and has not been determined experimentally.
