ACGIH: Not classifiable as a human carcinogen: Inadequate data on which to classify the agent in terms of

its carcinogencity in humans/animals. The value is for particulate matter containing no asbestos and 1%

crystalline silica.



Symptoms of overexposure:

       Inhalation: Repeated and prolonged exposure may cause beginnings Pneumoconiosis called

       Sideordsis.

       Eye Contact: May cause irritation.

       Skin Contact: May cause mechanical skin irritation.

       Ingestion: Expected to be non-toxic.



                                       10 mg/m3               10 mg/m3 (total)          0.2 mg/m3

Titanium Dioxide (TiO2)

                                                                                  5 mg/m3 (respirable)

Cas # 13463-67-7



Symptoms of overexposure:

       Inhalation: Inhalation of dust can cause irritation of the nose, throat, and lungs.

       Eye Contact: Like any foreign body, particles can cause mechanical irritation.

       Skin Contact: This material can cause irritation if not promptly washed form skin.

       Ingestion: This material is not expected to produce adverse effects.



                                       10 mg/m3               10 mg/m3 (Total)           5 mg/m3

Cas # 1314-13-2



Symptoms of overexposure:

       Inhalation: High levels of dust may result in tightness of chest, metallic taste, cough, dizziness,

       fever, chills, headache, nausea, and dry throat. Chronic exposure may produce symptoms known

       as metal fume fever or "zinc shakes", an acute, self-limiting condition without recognized

       complications. Symptoms of metal fume fever include: chills, fever, muscular pain, nausea and

       vomiting. May aggravate respiratory conditions.

       Eye Contact: May cause irritation.

       Skin Contact: May cause irritation.

       Ingestion: May cause irritation to the gastro-intestinal tract.
