If engineering controls and work practices are not effective in controlling exposure to this material, then wear suitable personal protective equipment including approved respiratory protection. Have appropriate equipment available for use in emergencies such as spills or fire.

If respiratory protection is required, institute a complete respiratory protection program including selection, fit testing, training, maintenance and inspection. Refer to the CSA Standard Z94.4-02, "Selection, Use, and Care of Respirators," available from the Canadian Standards Association.

RESPIRATORY PROTECTION GUIDELINES:

NIOSH RECOMMENDATIONS FOR TITANIUM DIOXIDE CONCENTRATIONS IN AIR (3):

AT ANY DETECTABLE CONCENTRATION: Positive pressure, full-facepiece SCBA; or positive pressure, full-facepiece SAR with an auxiliary positive pressure SCBA.

ESCAPE: Full-facepiece, air-purifying respirator with an N100, R100, or P100 filter; or escape-type SCBA.

NOTE: NIOSH has classified this material as a potential occupational carcinogen, according to specific NIOSH criteria. This classification is reflected in these recommendations for respiratory protection, which specify that only the most reliable and protective respirators be worn at any detectable concentration. NIOSH has changed their policy on respiratory protection for possible carcinogens but not yet revised these recommendations for respiratory protection. The requirements in Canadian jurisdictions may vary.

Recommendations apply only to NIOSH approved respirators.

The respirator use limitations specified by the approving agency and the manufacturer must be observed.

Air-purifying respirators do not protect against oxygen-deficient atmospheres.

ABBREVIATIONS: SAR = supplied-air respirator; SCBA = self-contained breathing apparatus. IDLH = Immediately Dangerous to Life or Health.
