4. First Aid Measures

Always seek medical attention after first aid measures are provided.

Inhalation: If inhaled, it will cause irritation and damage to the nose and throat. 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. It may lead to pain, nausea, vomiting, and even collapse. Contact medical center quickly. Never give anything by mouth to an unconscious person. Get medical attention.
Skin Contact: 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: It can cause severe damage to eyes. Check for and remove any contact lenses. Immediately flush your eyes with running water for at least 15 minutes, keeping eyelids open. Cold water may be used. Get medical attention.

5. Fire Fighting Measures

Fire: Flash point: 125C.
Toxic fumes, carbon dioxide, carbon monoxide may be formed in fire.
Auto-ignition temperature: 540C.
Fire Extinguishing Media: Dry chemical, foam or carbon dioxide and water spray jet.
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 a 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:
Small Spill: Mop and pick up the material and place in an appropriate waste disposal container. Soak up with inert absorbent material and dispose of it as hazardous waste. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements.
Large Spill: Contain spilled material. Cover with an inert, non-combustible absorbent material, (e.g., sand, earth, diatomaceous earth, vermiculite). Avoid mist formation. Wear full protective equipment and ensure proper ventilation. Keep away from heat. Keep away from sources of ignition. Provide ventilation. Vacuum or sweep up and remove to an approved disposal container. Contact Environment Agency.

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. Keep locked up in tightly closed container. Do not leave the material container open. Store protected from heat, sparks and ignition sources and incompatible materials. Do not ingest. Avoid contact with skin and eyes. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like Strong oxidizing agents, Strong alkalis, Acid chlorides Acid anhydrides. Containers may be hazardous when empty since they retain product residues. Do not store near food items.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits: This product does not contain any hazardous materials with occupational exposure limits established by the region-specific regulatory bodies.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is 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.
