Product Name & Other Names: Di-tert-butyl decarbonate or Di-t-butyl pyrocarbonate or Boc anhydride, Boc2O or Di-tert-butyldicarbonate.
CAS No.: 24424-99-5
EINECS EC No.: 246-240-1

4. First Aid Measures

Always seek medical attention after first aid measures are provided.

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.

5. Fire Fighting Measures

Flammability of the Product: Flammable.
Flash Points: 37C literature.
Products of Combustion: Carbon dioxide, Carbon monoxide, fumes.
Explosion: Explosive in presence of heat.
Fire Extinguishing Media: Use dry chemical, foam, water spray, carbon dioxide. 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 in order 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. Uninvolved persons should evacuate to a safe place. At high temperatures under fire conditions, it may produce toxic or irritating fumes.

6. Accidental Release Measures

Personal precautions, protective equipment, and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind. Do not touch the spilled material.
Environmental precautions: Do not let the product enter drains, soil, or water sources.
Methods and materials used for containment Cleanup procedures and Storage:
Small Spill: Avoid mist formation. Avoid breathing mist/vapors. 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: Remove all sources of ignition. Provide proper ventilation. Keep people away from and upwind of spill/leak. Entry to non-involved personnel should be controlled around the leakage area by roping off. Absorb the material on a porous, inert material such as earth, sand, or vermiculite. Carefully sweep 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.

7. Handling and Storage

Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. Wash thoroughly after handling. Do not drink, eat, or smoke while handling. Avoid contact with skin, eyes, and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Prevent any contact with hot surfaces. Wear suitable protective clothing. In case of insufficient ventilation, wear suitable respiratory equipment. Keep away from heat/sparks/open flame/hot surfaces. -No smoking. Take measures to prevent the buildup of electrostatic charge. Use explosion-proof equipment. Wash hands and face thoroughly after handling.
Conditions for safe storage, including any incompatibilities: Store in cool, dry, and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Do not leave the material container open. Store protected from light, heat, sparks and ignition sources and incompatible materials. Avoid contact with skin and eyes. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like strong acids, bases, oxidizing agents, reducing agents. Store locked up. Storage: 2C to 8C recommended.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits: Contains no substances with occupational exposure limit values.
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.
