2-vinylpyridine

Guidance on Safe Use

First-aid measures

In case of skin contact: Wash exposed area twice with soap and water. The exposed area should be examined by medical personnel if irritation or pain persists after the area has been washed. Due to this material's dermal toxicity, it is important to wash the exposed area without delay and GET MEDICAL ATTENTION as soon as possible. Vinegar may be used to ease irritation and to neutralize any remaining material after the area has been washed.

In case of eyes contact: Rinse eyes immediately with large amounts of water for at least 15 minutes, occasionally lifting the

eyelids. GET MEDICAL ATTENTION. Do not put vinegar in eyes.

In case of ingestion: Do NOT induce vomiting, this material is corrosive. Immediate dilution with milk or water is recommended, after which nothing should be administered orally until medical personnel have been contacted. Give oxygen if respiration is shallow. GET MEDICAL ATTENTION. Do not give anything by mouth to an unconscious person. Due to this material's corrosivity, it is essential to get medical attention as quickly as possible

In case of inhalation: Remove from exposure area to fresh air immediately. If breathing has stopped, give artificial respiration.

Keep affected person warm and at rest. GET MEDICAL ATTENTION.

Fire-fighting measures

Suitable extinguishing media: Water fog, alcohol foam, carbon dioxide, dry chemical. Use water to cool and dilute from as far a distance as possible.

Extinguishing media which must not be used for safety reasons: None in particular.

Special hazards arising from the substance or mixture: Toxic vapors may be released upon thermal decomposition (cyanides, nitrogen oxides, carbon monoxide). Severe explosion hazard in the form of vapor (within flammability limits) when exposed to heat, flame or static discharge.

Advice for firefighters: Wear self-contained breathing apparatus and full protective clothing (i.e., Bunker gear). Skin and eye contact should be avoided. Normal fire fighting procedures may be used.

Accidental release measures

Personal precautions, protective equipment and emergency procedures: Isolate the hazard area and deny entry to unnecessary and unprotected personnel.

Environmental precautions: Prevent releases to soils, drains, sewers and waterways.

Methods and material for containment and cleaning up: Remove all ignition sources. Ventilate the area of spill or leak. Wear protective equipment during clean-up. For small spills, use suitable absorbent material and collect for later disposal. For large spills, the area may require diking to contain the spill. Material can then be collected (eg., suction) for later disposal. After collection of material, flush area with water. Dispose of the material in accordance with standard practice for disposal of potentially hazardous materials as required by applicable federal, state or local laws.

Handling and storage

Precautions for safe handling: Precautions for Unique Hazards: This material is shipped with an inhibitor to prevent hazardous autopolymerization in storage and handling. The presence of oxygen is necessary to extend the life of the polymerization inhibitor; nitrogen blanketing of this material is not recommended. Contact Vertellus for detailed recommendations regarding bulk and drum storage.

Practices de Minimize Risk: Wear appropriate protective equipment when performing maintenance on contaminated equipment. Wash hands thoroughly before eating or smoking after handling this material. Do not eat, drink or smoke in work areas. Prevent contact with incompatible materials. Avoid spills and keep away from drains. Handle in a manner to prevent generation of aerosols, vapors or dust clouds.

Conditions for safe storage, including any incompatibilities: Maintain dry, ventilated conditions for storage. Protect containers against physical damage. Outside or detached storage is preferable. Inside storage should be in standard flammable liquids storage room or cabinet. Keep away from strong acids and oxidizing agents. This material should be stored at a temperature below -5°C (23°F). Avoid excessive heat, strong acids and oxidizing agents. Incompatibilities with materials of constitution: May cause some forms of plastics and rubbers to deteriorate.

Exposure controls / personal protection

Eye protection: Chemical goggles should be worn at all times; use face shields as conditions warrant.

Protection for skin: Impervious clothing and boots.

Protection for hands: Gloves to meet EN 374-1 or international equivalent. Fluororubber (Viton) or chemical-resistant laminate gloves are indicated for full-shift exposure. Neoprene, nitrile or PVC coated gloves provide short-term splash protection only (<30 mins).

Respiratory protection: Full face masks containing a suitable filter to remove specified gases & vapours and/or solid and liquid particles rated as APF 10 / 20 for applications requiring 90% and 95% respirator efficiency respectively.

Environmental exposure controls:  If user operations generate dust, fumes, gas, vapor or mist, use process enclosures, local exhaust ventilation or other engineering controls to keep worker exposure to airborne contaminants below any recommended or statutory limits.

Stability and reactivity

Reactivity: Not classified as dangerously reactive.

Chemical stability: Hazardous polymerization may occur.

Possibility of hazardous reactions: Self-accelerated decomposition temperature (SADT) testing has been performed on 2-Vinylpyridine. All packaging options for 2-Vinylpyridine were tested, and all had SADT's higher than 54°C. Therefore, 2-Vinylpyridine is not regulated under 49 CFR 173.21.

Conditions to avoid: This product must be stored below -5°C (23°F) in a dry environment. Allowing the material to heat uncontrollably or to absorb water and/or impurities can promote autopolymerization into vinylpyridine polymer.

Incompatible materials: Avoid excessive heat, strong acids and oxidizing agents.

Hazardous decomposition products: Toxic vapors may be released upon thermal decomposition (cyanides, nitrogen oxides, carbon monoxide).

Disposal considerations

Generator is responsible for proper waste characterization. State hazardous waste regulations may differ substantially from federal regulations. Dispose of this material responsibly, and in accordance with standard practice for disposal of potentially hazardous materials as required by applicable

international, national, regional, state or local laws, and environmental protection duty of care principles. Do NOT dump into any sewers, on the ground, or into any body of water. For disposal within the EC, the appropriate classification code according to the European Community List of Wastes should be used. Note that disposal regulations may also apply to empty containers and equipment rinsates.
