Product Name & Other Names: 4-Nitropphenyl Chloroformate or 4-Nitrophenyl Carbonochloridate or Chloroformic Acid 4-Nitrophenyl Ester.
CAS No.: 7693-46-1
EINECS EC Code: 231-706-94. First Aid Measures
Always seek medical attention after first aid measures are provided.
Inhalation: If inhaled, it will cause irritation and damage. Remove the victim to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
Ingestion: It will cause irritation and burns to mouth, digestive tract and stomach. Contact medical center quickly. Never give anything by mouth to an unconscious person. Get medical attention.
Skin Contact: Causes skin burns. On contact, it can cause itching, pain, swelling and redness. 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.
Eye Contact: Causes eye burns. It can cause severe irritation and harm to eyes. Check for and remove any contact lenses. Immediately flush eyes with running water for at least 15 minutes, keeping eyelids open. Cold water may be used. Get medical attention.
Notes to Physician: Treat symptomatically.5. Fire Fighting Measures
Fire: Toxic fumes, hydrogen chloride gas, nitrogen oxides, chlorine and complex material may be formed in fire.
Explosion: No data available. Explosive decomposition possible on heating.
Fire Extinguishing Media: Dry chemical, foam or carbon dioxide and water spray jet. Avoid solid water jet. For this substance/mixture no limitations of extinguishing agents are given.
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.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: Contain spilled material. Sweep up and shovel and dispose of as hazardous waste. Keep in suitable, closed containers for disposal. Avoid dust formation. Keep away from heat. Keep away from sources of ignition. Wear full protective equipment and ensure ventilation.7. Handling and Storage
Precautions for safe handling: Keep away from heat and source of fire preferably in a ventilated area. 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. 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.
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 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 alkalis. oxidizing agents. Containers of may be hazardous when empty since they retain product residues. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Store away from oxidizing agents. Storage: Refrigerated. Moisture Sensitive, Heat Sensitive.8. Exposure Controls/Personal Protection
Airborne Exposure Limits: Not established.
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. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to the substance is apparent and engineering controls are not feasible, consult an industrial hygienist. For emergencies, or instances where the exposure levels are not known, use a full-face piece positive-pressure, air-supplied respirator. WARNING: Air purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection: Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection: Use chemical safety goggles and/or a full-face shield where splashing 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.9. Physical and Chemical Properties
