5. Fire Fighting Measures
Flammability of the Product: May be combustible at high temperature..
Auto-Ignition Temperature: 470C (878F).
Flash Points: CLOSED CUP: 118.3C (244.9F).
Products of Combustion: Carbon dioxide, Carbon monoxide, Hydrogen Chlorides, Fumes.
Fire Extinguishing Media: Use any means suitable for extinguishing surrounding fire. Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide.
Extinguishing Media Not recommended: Avoid using solid water jet as it may scatter the fire.
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.
6. Accidental Release Measures
Personal precautions, protective equipment, and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Ensure adequate ventilation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Do not approach facing the wind.
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: Contain spilled material. Avoid dust formation. Avoid breathing dust. Ensure adequate ventilation. Use appropriate tools to put the spilled solid in a convenient waste disposal container.
Large Spill: Avoid touching the spilled material. Do not let the product enter drains. Use a shovel to put the material into a convenient waste disposal container. Do not contaminate the environment.
7. Handling and Storage
Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. In case of insufficient ventilation, wear suitable respiratory equipment. 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 oxidizing agents, reducing agents, metals, and acids.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits: Although up to 10mg/m3 is prescribed in some regulations, better limit it to 2mg/m3.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible.
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.
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.

Hazardous Polymerization: Will not occur.
Incompatibilities: Strong oxidizing agents, reducing agents metals and acids.
Conditions to Avoid: Incompatibles and moisture.
Phenols are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides.
Avoid use of aluminum, copper and brass alloys in storage and process equipment.
Heat is generated by the acid-base reaction between phenols and bases.
Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature), these reactions generate heat.
Phenols are nitrated very rapidly, even by dilute nitric acid.
Nitrated phenols often explode when heated. Many of them form metal salts that tend toward detonation by rather mild shock.
Segregate from oleum, nitric acid and chlorosulfonic acid.
