Exposure Guidelines
A: General Product Information
Concrete stone veneer contains mineral dust and crystalline silica, which may be released as dust when dry
cutting, sawing, grinding, sanding, or drilling. Follow all applicable exposure limits if dusts are generated.
B: Component Exposure Limits
Portland cement (65997-15-1)
ACGIH: 10 mg/m3 TWA (particulate matter containing no asbestos and <1% crystalline silica)
OSHA: 10 mg/m3 TWA (total dust); 5 mg/m3 TWA (respirable fraction)
NIOSH: 10 mg/m3 TWA (total dust); 5 mg/m3 TWA (respirable dust)
Quartz (14808-60-7)
ACGIH: 0.025 mg/m3 TWA (respirable fraction)
OSHA: 0.1 mg/m3 TWA (respirable dust)
NIOSH: 0.05 mg/m3 TWA (respirable dust)
Aluminum oxide (1344-28-1)
OSHA: 10 mg/m3 TWA (total dust); 5 mg/m3 TWA (respirable fraction)
Sodium hydroxide (1310-73-2)
ACGIH: 2 mg/m3 Ceiling
OSHA: 2 mg/m3 Ceiling
NIOSH: 2 mg/m3 Ceiling
Iron oxide (1309-37-1)
ACGIH: 5 mg/m3 TWA (respirable fraction)
OSHA: 10 mg/m3 TWA (fume)
NIOSH: 5 mg/m3 TWA (Fe, dust and fume)
Calcium oxide (1305-78-8)
ACGIH: 2 mg/m3 TWA
OSHA: 5 mg/m3 TWA (not in effect as a result of reconsideration)
NIOSH: 2 mg/m3 TWA
Magnesium oxide fume (1309-48-4)
ACGIH: 10 mg/m3 TWA (inhalable fraction)
OSHA: 10 mg/m3 TWA (total particulate)
Engineering Controls
ACGIH and OSHA have determined that adverse effects are not likely to occur in the workplace provided
exposure levels do not exceed the appropriate TLV/PEL. However, because of the wide variation in individual
susceptibility, lower exposure limits may be appropriate for some individuals, including persons with pre-existing
medical conditions such as those described below.
Ventilation:
General dilution ventilation and/or local exhaust ventilation should be provided as necessary to maintain
exposures below occupational exposure limits. Dust collection systems may be necessary in some operations.
Local Exhaust Ventilation:
When dry cutting, sawing, grinding, breaking, or drilling precast stone veneer, use sufficient local exhaust to
reduce the level of respirable dust to the applicable standards set forth in Section II. See ACGIH “Industrial
Ventilation, A Manual of Recommended Practice.” Latest edition.
Work/Hygienic Practices:
Avoid creating and breathing dust. Do not eat, drink, or smoke in the work area.
