Section 8 - Exposure Controls / Personal Protection
Applicable Exposure Limits:
For Particulates Not Otherwise Regulated:
OSHA PEL (8-hour TWA)
15 mg/m
3
total dust
5 mg/m
3
respirable dust
For Crystalline Silica (respirable):
OSHA PEL (8-hour TWA) NIOSH 8-hour TWA IDLH
0.1 mg/m
3
0.05 mg/m
3
50 mg/m

For Cristobalite:
ACGIH-TLV (8-hour TWA) IDLH
0.05 mg/m
3
25 mg/m

CAUTION: Crystalline silica exists in several forms, the most common of which is
quartz. If crystalline silica (quartz) is heated to more than 870
o
C (1,598
o
F) it can change
to a form of crystalline silica known as trydimite, and if crystalline silica (quartz) is
heated to more than 1,470
o
C (2,678
o
F) it can change to a form of crystalline silica
known as cristobalite. Crystalline silica as trydimite and cristobalite are more fibrogenic
than crystalline silica as quartz. The OSHA PEL for crystalline silica as trydimite and
cristobalite is one-half the PEL for crystalline silica as quartz; the ACGIH TLV for
crystalline silica as trydimite and cristobalite is one-half the TLV for crystalline silica as
quartz.
Recommended Engineering Controls: Provide adequate exhaust ventilation.
Cutting Instructions: Do not dry cut tile with power tools. Do use wet saw or the score
and snap method to cut tile. Improper techniques could expose the installer to harmful
silica dust
Recommended Administrative Controls: Train employees on the hazards of fired tile
particulates.
Recommended Personal Protective Equipment (PPE): Wear goggles if there is
likelihood of contact with eyes. Utilize NIOSH-approved respiratory protective
equipment as necessary in atmospheres containing concentrations of respirable silica in
excess of the PEL. Utilize either an air-purifying respirator fitted with a particulate filter
or an atmosphere-supplying respirator, as warranted by the airborne concentration.
Recommended Hygiene Practices: Clean PPE and work clothing contaminated with
fired tile particulates prior to reuse. After working with this product, be sure to wash
before eating, smoking, drinking, or applying cosmetics.
Respirable particulates are of negligible concern as long as the material (fired tile) is not
being cut, crushed, or otherwise broken.
