Potential Health Effects
----------------------------------
Inhalation:
May cause mild irritation to the respiratory
tract.
Ingestion:
Not expected to be a health hazard via
ingestion.
Skin Contact:
May cause mild irritation and redness.
Eye Contact:
May cause mild irritation, possible reddening.
Chronic Exposure:
Long-term exposure to titanium dioxide dust
may result in mild fibrosis (scarring of the lungs).
Aggravation of
Pre-existing Conditions:
Persons with pre-existing lung disease may be
more susceptible to the effects of this substance.
4. First Aid Measures
Inhalation:
Remove to fresh air. Get medical attention
for any breathing difficulty.
Ingestion:
Not expected to
require first aid measures. If large amounts were swallowed, give water to
drink and get medical advice.
Skin Contact:
Immediately flush
skin with plenty of soap and water for at least 15 minutes. Remove
contaminated clothing and shoes. Wash clothing before reuse. Thoroughly clean
shoes before reuse. Get medical attention if irritation develops.
Eye
Contact:
Immediately flush eyes with plenty of water for at least 15
minutes, lifting upper and lower eyelids occasionally. Get medical attention
if irritation persists.
5. Fire Fighting Measures
Fire:
Not considered to be a fire hazard.
Explosion:
Not considered to be an explosion hazard.
Fire Extinguishing Media:
Use any means suitable for
extinguishing surrounding fire.
Special Information:
In the
event of a fire, wear full protective clothing and NIOSH-approved
self-contained breathing apparatus with full facepiece operated in the
pressure demand or other positive pressure mode.
6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal
protective equipment as specified in Section 8. Spills: Sweep up and
containerize for reclamation or disposal. Vacuuming or wet sweeping may be
used to avoid dust dispersal.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry,
ventilated area. Protect against physical damage. Containers of this material
may be hazardous when empty since they retain product residues (dust, solids);
observe all warnings and precautions listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
Titanium Dioxide:
- OSHA
Permissible Exposure Limit (PEL) -
15 mg/m3 (TWA).
- ACGIH Threshold
Limit Value (TLV) -
10 mg/m3 (TWA), A4 - Not classifiable as a human
carcinogen.
Ventilation System:
A system of local and/or
general exhaust is recommended to keep employee exposures below the Airborne
Exposure Limits. Local exhaust ventilation is generally preferred because it
can control the emissions of the contaminant at its source, preventing
dispersion of it into the general work area. Please refer to the ACGIH
document, Industrial Ventilation, A Manual of Recommended Practices,
most recent edition, for details.
Personal Respirators (NIOSH
Approved):
If the exposure limit is exceeded, a half-face dust/mist
respirator may be worn for up to ten times the exposure limit or the maximum
use concentration specified by the appropriate regulatory agency or respirator
supplier, whichever is lowest. A full-face piece dust/mist respirator may be
worn up to 50 times the exposure limit, or the maximum use concentration
specified by the appropriate regulatory agency, or respirator supplier,
whichever is lowest. For emergencies or instances where the exposure levels
are not known, use a full-facepiece positive-pressure, air-supplied
respirator. WARNING: Air-purifying respirators do not protect workers in
oxygen-deficient atmospheres.
Skin Protection:
Wear protective
gloves and clean body-covering clothing.
Eye Protection:
Use
chemical safety goggles and/or full face shield where dusting or splashing of
solutions is possible. Maintain eye wash fountain and quick-drench facilities
in work area.
