NIOSH Registry of Toxic Effects of Chemical Substances (RTECS) Identification Number: VV8770000

Chemical Description and Physical Properties:

fine grey powder used for the manufacture of concrete
molecular weight: Variable
vapor pressure: approx. 0 mm

Incompatibilities: None hazardous

OSHA Permissible Exposure Limit (PEL):

General Industry: 50 mppcf (Silicates) (Z-3)

National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 5 mg/m³ TWA

Potential Symptoms: Eye, nose irritation; coughing, expectoration, exertional dyspnea, wheezing, chronic bronchitis; dermatitis

Health Effects: Nuisance particulate (HE19) If quartz content is less than 1%. Irritation-Eye, Nose---Mild (HE16) IC_CAS_NUMBEL1165997-15-1^*

Affected Organs: Respiratory system, eyes, skin

Primary Laboratory Sampling/Analytical Method (SLC1):

• sampling media: Tared Low Ash Polyvinyl Chloride (LAPVC) filter 5 microns preceded by 10 mm nylon cyclone
  maximum volume: 816 Liters
  maximum flow rate: 1.7 L/min
  current analytical method: Gravimetric analysis followed by X-ray Diffraction
  method reference: 11, 12, 2 (OSHA ID-142)
  method classification: Fully Validated
  note: Gravimetric analysis is field method for determining compliance with respirable Portland Cement standard. Following this analysis, submit sample to the Salt Lake Technical Center for X-ray diffraction analysis of respirable Quartz. Compliance can then be determined for both standards. If filter is not overloaded, samples may be collected up to an 8-hour period. Submit bulk sample in separate mailing container at time air samples are submitted.
