First Aid Measures

Inhalation: Move person to fresh air right away. Give oxygen if breathing is difficult. Seek medical attention without delay for persistent coughing or shortness of breath.
Skin Contact: Immediately flush skin with plenty of running water, remove contaminated clothing and wash skin with mild soap. Get medical help if irritation does not subside.
Eye Contact: Rinse eyes under gently running water for at least 20 minutes, holding eyelids open. Remove contact lenses. Get medical aid at once.
Ingestion: Rinse mouth with water. Do not induce vomiting. Get medical advice immediately. Provide the product label or MSDS to the medical provider.
Most Important Symptoms: Redness, itching, pain, burning sensation on skin and in eyes, respiratory discomfort. Delayed onset of symptoms can occur.

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical, foam.
Unsuitable Media: Do not use direct water jet, as it may spread burning material.
Hazards from Combustion: Rapid decomposition, releasing flammable gases and vapors. Risk of explosion in confined spaces.
Protective Actions: Approach from upwind, keep containers cool with water spray, isolate area, use non-sparking tools.
Special Protective Equipment: Full protective gear and self-contained breathing apparatus required for firefighters.
Additional Information: Evacuate area if possible, keep unauthorized persons away, avoid inhaling fumes.

Accidental Release Measures

Personal Precautions: Wear protective equipment including gloves, goggles, chemical-resistant clothing. Remove sources of ignition.
Environmental Precautions: Prevent run-off into drains or waterways. Block any direct flow to sewers.
Methods for Clean-Up: Use non-sparking tools to lightly cover spillage with inert absorbent material (such as sand, vermiculite), then place in properly labeled containers for disposal.
Other Precautions: Avoid raising dust, ventilate affected area, report major spills to appropriate authorities as required by regulations.

Handling and Storage

Safe Handling: Handle using non-sparking tools and explosion-proof equipment. Do not expose to friction, shock, or heat. Work in a well-ventilated place.
Storage Conditions: Store in tightly closed containers, away from sunlight and incompatible substances like acids, bases, reducing agents. Keep between 2-8°C in a cool, dry, ventilated location.
Special Precautions: Keep away from food and drink, avoid any contamination, label storage area clearly.
Incompatibilities: Strong acids, bases, reducing agents, oxidizers, and combustible materials.

Exposure Controls and Personal Protection

Exposure Limits: No specific occupational exposure limits set for this material; follow good industrial hygiene practices.
Engineering Controls: Use local exhaust ventilation or containment to reduce exposure. Install explosion-proof ventilation.
Personal Protection: Chemical-resistant gloves, splash-proof goggles or face shield, lab coat or chemical apron, closed shoes. Respirator recommended for high vapor/dust concentrations.
Hygiene Measures: Wash thoroughly after handling, take off contaminated clothing before entering common areas.
Environmental Controls: Avoid release to the environment, use procedures to protect waterways.
