Product Name/Synonyms: Tert-Butyl Perbenzoate or Tert-Butyl Per Benzoate or TBPB or Perbenzoic acid tert-butyl ester or Peroxybenzoic acid tert-butyl ester.
CAS No.: 614-45-9
EINECS EC No.: 210-382-2

Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
Ingestion: Never give anything by mouth to an unconscious person. Get medical attention.
Skin Contact: Wipe off excess material from skin then immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention.
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.
Note to physicians: Treat symptomatically.

Flammability of the Product: Combustible.
Auto-Ignition Temperature: SADT: 60C.
Flash Points: 80C
Products of Combustion: Carbon dioxide, Carbon monoxide, fumes.
Fire: Inflammable.
Explosion: Explosive in presence of heat.
Fire Extinguishing Media: Use Water spray, Carbon dioxide (CO2), Foam, Dry powder and Sand for extinction. Flammable liquid and vapor. 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. Never direct a water jet in the container to prevent any splashing of the product which could cause spreading of the fire. Cool containing vessels with water jet in order to prevent pressure build-up, auto-ignition or explosion.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures under fire conditions, it may produce toxic or irritating fumes. Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place.

Personal precautions, protective equipment, environmental precautions, and emergency procedures: Avoid mist formation. Avoid breathing mist. Ensure adequate ventilation. Use appropriate tools to put the spilled solid in a convenient waste disposal container. Use personal protective equipment for large spills.
Methods and materials used for containment Cleanup procedures and Storage:
Small Spill: Avoid mist formation. Avoid breathing mist. Ensure adequate ventilation. Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements.
Large Spill: Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided. Remove all sources of ignition. Provide proper ventilation. If liquid - absorb the material on a porous, inert material such as earth, sand, or vermiculite. Carefully sweep solid/powder up the material without causing dust. Dispose of in accordance with local regulations.
Large liquid spillages should be contained by use of sand or another inert material. The spillage should be transferred to a suitable container and recovered or disposed of in accordance with local regulations. Because of the danger of spontaneous combustion, any combustible material, such as cloth, used for cleaning spillages, should be saturated with water, and disposed of promptly, preferably by incineration.

Precautions for safe handling: Do not ingest. Do not breathe dust or mist. Wear suitable protective clothing. In case of insufficient ventilation, wear suitable respiratory equipment.
Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Wash hands thoroughly after handling. Provide appropriate exhaust ventilation at places where dust is formed. If you feel unwell, seek medical attention.
Conditions for safe storage, including any incompatibilities: Keep in a tightly closed container, stored in a cool, dry, ventilated area. Keep the product in its original container well sealed, in a dry and ventilated area, away from potential sources of ignition and protected from light. Protect against physical damage. Recommended storage temperature below 20C. Store temperatures should never exceed 38C.

Airborne Exposure Limits: This product does not contain any hazardous materials with occupational exposure limits established by the region-specific regulatory bodies. Keep at low exposure level.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Handle in accordance with good industrial hygiene and safety practice. Wash hands after handling. Ensure that eyewash stations and safety showers are close to the workstation location. Ensure adequate ventilation, especially in confined areas.
