We expect this update to take about an hour. Access to this website will be unavailable during this time.
CAS Registry No.: 108-88-3
Other Names: Methylbenzene, Toluol
Main Uses: Manufacture of other chemicals, solvent.
Appearance: Clear colourless liquid.
Canadian TDG: UN1294
B2 - Flammable Liquid; D2A - Very Toxic (Teratogenicity/embryotoxicity); D2B - Toxic (Skin irritant)
Emergency Overview: Clear colourless liquid. Aromatic odour. HIGHLY FLAMMABLE LIQUID AND VAPOUR. Distant ignition and flashback are possible. Can accumulate static charge. Can float on water and spread fire. CONFINED SPACE HAZARD. Can accumulate in hazardous amounts in low-lying areas especially inside confined spaces. May cause drowsiness and dizziness. IRRITANT. Causes moderate or severe skin irritation. ASPIRATION hazard. May be fatal if swallowed and enters airways. TERATOGEN/EMBRYOTOXIN. May damage the unborn child.
Main Routes of Exposure: Inhalation. Skin contact. Eye contact.
International Agency for Research on Cancer (IARC): Group 3 - Not classifiable as to its carcinogenicity to humans.
American Conference for Governmental Industrial Hygienists (ACGIH): A4 - Not classifiable as a human carcinogen.
Inhalation: Take precautions to prevent a fire (e.g. remove sources of ignition). Move victim to fresh air. Call a Poison Centre or doctor if the victim feels unwell.
Skin Contact: Avoid direct contact. Wear chemical protective clothing if necessary. Quickly take off contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Quickly and gently blot or brush away excess chemical. Immediately wash gently and thoroughly with lukewarm, gently flowing water and non-abrasive soap for 15-20 minutes. If irritation or pain persists, see a doctor. Thoroughly clean clothing, shoes and leather goods before reuse or dispose of safely.
Eye Contact: Avoid direct contact. Wear chemical protective gloves if necessary. 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. If vomiting occurs naturally, have victim lean forward to reduce risk of aspiration. Have victim rinse mouth with water again. Immediately call a Poison Centre or doctor.
First Aid Comments: 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: HIGHLY FLAMMABLE LIQUID. Can ignite at room temperature. Releases vapour that can form explosive mixture with air. Can be ignited by static discharge.
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, appropriate foam, water spray or fog. Foam manufacturers should be consulted for recommendations regarding types of foams and application rates. Use water to keep non-leaking, fire-exposed containers cool.
Specific Hazards Arising from the Chemical: Liquid can float on water and may travel to distant locations and/or spread fire. Liquid can accumulate static charge by flow, splashing or agitation. Vapour may travel a considerable distance to a source of ignition and flash back to a leak or open container. Vapour may accumulate in hazardous amounts in low-lying areas especially inside confined spaces, resulting in a toxicity hazard. Closed containers may rupture violently when heated releasing contents. In a fire, the following hazardous materials may be generated: very toxic carbon monoxide, carbon dioxide; reactive chemicals; toxic, flammable aldehydes; and other chemicals.
Personal Precautions: Evacuate the area immediately. Isolate the hazard area. Keep out unnecessary and unprotected personnel. Eliminate all ignition sources. Use grounded, explosion-proof equipment.
Methods for Containment and Clean-up: Stop or reduce leak if safe to do so. Small spills or leaks: contain and soak up spill with absorbent that does not react with spilled product. Large spills or leaks: contact emergency services and manufacturer/supplier for advice.
Other Information: Report spills to local health, safety and environmental authorities, as required.
Handling: In the event of a spill or leak, exit the area immediately. Eliminate heat and ignition sources such as sparks, open flames, hot surfaces and static discharge. Post "No Smoking" signs. Avoid generating vapours or mists. Electrically bond and ground equipment. Ground clips must contact bare metal. Avoid repeated or prolonged skin contact with product or with contaminated equipment/surfaces.
Storage: Store in an area that is: cool, well-ventilated, out of direct sunlight and away from heat and ignition sources, clear of combustible and flammable materials (e.g. old rags, cardboard), separate from incompatible materials. Keep amount in storage to a minimum. Electrically bond and ground containers. Ground clips must contact bare metal. Avoid bulk storage indoors.
ACGIH® TLV® - TWA: 20 ppm A4 BEI®
Exposure Guideline Comments: TLV® = Threshold Limit Value. TWA = Time-Weighted Average. A4 = Not classifiable as a human carcinogen. BEI® = Biological Exposure Index.
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. For large scale use of this product: use non-sparking ventilation systems, approved explosion-proof equipment and intrinsically safe electrical systems in areas where this product is used and stored. Control static electricity discharges which includes bonding of equipment to ground.
Eye/Face Protection: Wear chemical safety goggles and face shield when contact is possible.
Skin Protection: Wear chemical protective clothing e.g. gloves, aprons, boots. Suitable materials include: polyvinyl alcohol, Viton®, Barrier® - PE/PA/PE, Silver Shield® - PE/EVAL/PE, Tychem® Responder® CSM , Trellchem® HPS, Trellchem® VPS, Tychem® BR/LV, Tychem® TK.
Up to 500 ppm:
(APF = 10) Any chemical cartridge respirator with organic vapor cartridge(s)*; or Any supplied-air respirator*.
(APF = 25) Any powered, air-purifying respirator with organic vapor cartridge(s)*.
(APF = 50) Any air-purifying, full-facepiece respirator (gas mask) with a chin-style, front- or back-mounted organic vapor canister; or Any self-contained breathing apparatus with a full facepiece.
*Reported to cause eye irritation or damage; may require eye protection.
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.
