First Aid
• If large amounts of TiO2 are inhaled, remove victim to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician.
• In case of eye contact, immediately flush with water for at least 15 min. Call a physician. In case of skin contact, the compound is not likely to be hazardous, but cleaning the skin after use is advised.
Safety Precautions
• Titanium dioxide is classified as a nuisance dust.
Follow all local regulations and DuPont recommendations for exposure limits as described in
the Material Safety Data Sheet (MSDS).
If the recommended exposure limits of TiO2 are to be
exceeded, NIOSH-approved air-purifying respirators with particulate filters should be used.
As a matter of good industrial hygiene, gloves and safety glasses with side shields or better eye
protection should be worn when handling TiO2. For more details, refer to the MSDS.
