We expect this update to take about an hour. Access to this website will be unavailable during this time.
CAS Registry No.: 13463-67-7
Other Names: TiO2, Titanium white
Main Uses: Pigment, filler, opacifying agent
Appearance: White powder.
Canadian TDG: Not specifically listed in Canadian TDG Regulations, but may be regulated as part of a chemical family or group Not Otherwise Specified (N.O.S.). Consult the regulations.
D2A - Very Toxic (Carcinogenicity)
Emergency Overview: White powder. Odourless. Will not burn. SUSPECT CANCER HAZARD. Suspected of causing cancer, if inhaled.
Main Routes of Exposure: Inhalation; skin contact; eye contact.
International Agency for Research on Cancer (IARC): Group 2B - Possibly carcinogenic to humans.
American Conference for Governmental Industrial Hygienists (ACGIH): A4 - Not classifiable as a human carcinogen.*Under review by ACGIH.
Inhalation: Take precautions to ensure your own safety before attempting rescue (e.g. wear appropriate protective equipment). Move victim to fresh air.
Skin Contact: Quickly and gently blot or brush away excess chemical. Wash gently and thoroughly with lukewarm, gently flowing water and non-abrasive soap for 5 minutes.
Eye Contact: Quickly and gently blot or brush chemical off the face. Immediately flush the contaminated eye(s) with lukewarm, gently flowing water for 5 minutes, while holding the eyelid(s) open. If irritation or pain persists, see a doctor.
Ingestion: Have victim rinse mouth with water. Call a Poison Centre or doctor if the victim feels unwell.
First Aid Comments: If exposed or concerned, see a doctor for medical advice. All first aid procedures should be periodically reviewed by a doctor familiar with the chemical and its conditions of use in the workplace.
Flammable Properties: Does not burn.
Suitable Extinguishing Media: Not combustible. Use extinguishing agent suitable for surrounding fire.
Specific Hazards Arising from the Chemical: None known.
Personal Precautions: Keep unnecessary and unprotected personnel out of spill area. Use personal protective equipment as required.
Methods for Containment and Clean-up: Avoid generating dust. Collect using shovel/scoop or approved HEPA vacuum and place in a suitable container for disposal. Avoid dry sweeping. If necessary, use a dust suppressant such as water. Do not use compressed air for clean-up.
Handling: Before handling, it is important that all engineering controls are operating and that protective equipment requirements and personal hygiene measures are being followed. Immediately report leaks, spills or failures of the safety equipment (e.g. ventilation system). Avoid generating dusts. Keep containers tightly closed when not in use or empty. Prevent accidental contact with incompatible chemicals.
Storage: Store in tightly closed, properly labelled containers.
ACGIH® TLV® - TWA: 10 mg/m3 A4
Exposure Guideline Comments: TLV® = Threshold Limit Value. TWA = Time-Weighted Average. A4 = Not classifiable as a human carcinogen.
NOTE: In many (but not all) Canadian jurisdictions, the exposure limits are similar to the ACGIH® TLVs®. Since legislation varies by jurisdiction, contact your local jurisdiction for exact details. A list is available in the OSH Answers on Canadian Governmental Occupational Health & Safety Departments.
A list of which acts and regulations that cover exposure limits to chemical and biological agents is available on our website. Please note that while you can see the list of legislation for free, you will need a subscription to view the actual documentation.
Engineering Controls: Use a local exhaust ventilation and enclosure, if necessary, to control amount in the air.
Eye/Face Protection: Wear chemical safety goggles.
Skin Protection: Coveralls or long sleeve shirts and pants.
At concentrations above the NIOSH REL, or where there is no REL, at any detectable concentration:
(APF = 10,000) Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode; or Any supplied-air respirator that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary self-contained positive-pressure breathing apparatus.
APF = Assigned Protection Factor
Recommendations apply only to National Institute for Occupational Safety and Health (NIOSH) approved respirators. Refer to the NIOSH Pocket Guide to Chemical Hazards for more information.
NOTE: NIOSH has classified this substance 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.
