Section 2 - COMPOSITION, INFORMATION ON INGREDIENTS
Risk Phrases: 11 20/21/22 35
Section 3 - HAZARDS IDENTIFICATION
Highly flammable. Harmful by inhalation, in contact with skin and if swallowed. Causes severe burns.
Potential Health Effects
Causes severe eye burns. May result in corneal injury. Low vapor concentrations may cause a temporary visual disturbance known as 'blue haze' or 'halo vision'.
Harmful if absorbed through the skin. Causes skin burns.
Harmful if swallowed. Causes gastrointestinal tract burns.
Harmful if inhaled. May cause irritation of the respiratory tract with burning pain in the nose and throat, coughing, wheezing, shortness of breath and pulmonary edema.
No information found.
Section 4 - FIRST AID MEASURES
Eyes: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical aid immediately.
In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give anything by mouth to an unconscious person.
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Section 5 - FIRE FIGHTING MEASURES
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire. May accumulate static electrical charges, and may cause ignition of its own vapors. Extremely flammable liquid and vapor. Vapor may cause flash fire. Vapors are heavier than air and may travel to a source of ignition and flash back. Vapors can spread along the ground and collect in low or confined areas.
Use water spray, dry chemical, "alcohol resistant" foam, or carbon dioxide.
Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Remove all sources of ignition.
Use a spark-proof tool. Provide ventilation. Use water spray to cool and disperse vapors, protect personnel, and dilute spills to form nonflammable mixtures.
Section 7 - HANDLING and STORAGE
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Do not get in eyes, on skin, or on clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Take precautionary measures against static discharges. Keep container tightly closed. Discard contaminated shoes. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Use only with adequate ventilation.
Keep away from heat, sparks and flame. Do not breathe vapor or mist.
Keep away from sources of ignition. Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances. Flammables-area. Isolate from oxidizing materials and acids.
Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate ventilation to keep airborne concentrations low. Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
Exposure Limits CAS# 109-73-9: United States OSHA: ; 5 ppm Ceiling; 15 mg/m3 Ceiling Belgium - TWA: 5 ppm VLE; 15 mg/m3 VLE France - VLE: 5 ppm VLE; 15 mg/m3 VLE Germany: 5 ppm TWA; 15 mg/m3 TWA Germany: Skin absorber Japan: 5 ppm Ceiling; 15 mg/m3 Ceiling Malaysia: 5 ppm Ceiling; 15 mg/m3 Ceiling Russia: 10 mg/m3 TWA Spain: 5 ppm VLA-EC (all isomers); 15 mg/m3 VLA-EC (all isomers) Personal Protective Equipment Eyes: Wear chemical splash goggles.
Wear appropriate protective gloves to prevent skin exposure.
Wear appropriate protective clothing to prevent skin exposure.
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant respirator use. Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
