2-benzyl-2-methyl-3-butenitrile

Guidance on Safe Use

First-aid measures

In case of inhalation:

      Move affected person into fresh air, keep warm and allow to rest.

In case of skin (or hair) contact:

      Wash immediately with water and soap.

In case of eye contact:

      In case of contact with eyes flush immediately with plenty of flowing water for 10 to 15 minutes holding eyelids apart and consult an

      ophthalmologist if problems persist.

In case of ingestion:

      Rinse mouth immediately and drink plenty of water and seek medical advice.

Fire-fighting measures

Extinguishing media:

Suitable extinguishing media:       Dry extinguishing powder; carbon dioxide (CO2); foam.

Unsuitable extinguishing media: Full water jet.

Special hazards arising from the substance:

In case of fire may be liberated: carbon dioxide (CO2), carbon monoxide (CO), toxic pyrolysis products.

Advice for fire-fighters:

Wear a self-contained breathing apparatus and chemical protective clothing.

Dispose of fire debris and contaminated extinguishing water in accordance with official regulations.

Keep containers cool by spaying with water if exposed to fire.

Accidental release measures

Personal precautions, protective equipment and emergency procedures:

for non-emergency personnel:

      Provide adequate ventilation.

      Avoid contact with skin, eyes and clothing.

      Wear protective gloves/protective clothing/eye protection/face protection.

      Remove all sources of ignition, avoid heat and sparks.

for emergency responders:

      In case of large amounts wear a self-contained breathing apparatus and chemical protective clothing. No further precautions.

Environmental precautions:

      Do not allow to enter drains/surface water/ground-water.

      Do not allow to enter into soil/subsoil.

      In case of entry into waterways, soil or drains, inform the responsible authorities.

      Treat the recovered material as prescribed in the section on waste disposal.

Methods and material for containment and cleaning up:

      For large amount: dike spillage. Pump off product.

      For residues: Pick up with suitable absorbent material

      Suitable material for taking up: universal binder.

Handling and storage

Precautions for safe handling:

      Use only in well-ventilated areas.

      It is recommended to design all work processes always so that the following is excluded:

      Inhalation, skin contact, eye contact.

      Only use the material in places where open light, fire and other flammable sources can be kept away.

      Take precautionary measures against static discharges.

      Vapours can form an explosive mixture with air.

Conditions for safe storage, including any incompatibilities

      Technical measures and storage conditions:

      Store in the original container.

      Keep container tightly closed. Keep in a cool, dry, well-ventilated place.

      Floor should be sealed, jointless, solvent-resistant and not adsorbent.

Exposure controls / personal protection

Exposure controls:

2-Benzyl-2-methylbut-3-enenitrile,       CAS-No.: 97384-48-0

To date, no national critical limit values exist.

Personal protective equipment:

Eye / face protection:

      Suitable eye protection: Eye glasses with side protection (according to EN 166).

Skin protection:

      - Hand protection:

      - By long-term hand contact:

         Suitable gloves type (recommended protective index 6, corresponding >480 min of permeation time according to EN 374):

         Butyl caoutchouc (butyl rubber), 0.7 mm coating thickness

      - By short-term hand contact:

         Suitable gloves type (recommended at least protective index 2, corresponding >30 min of permeation time according to EN 374):

         CR (polychloroprene, chloroprene rubber) 0,5 mm coating thickness.

Supplementary note:

The specifications are based on literature and information of glove manufacturer or are derived from similar substances by analogy. Due to many conditions (e.g. temperature) it must be considered, that the practical usage of a chemical-protective glove in practice may be much shorter than the determined permeation time.

For special purposes, it is recommended to check the resistance to chemicals of the protective gloves mentioned above together with the supplier of these gloves.

      - Other: Suitable protective clothing:

         In normal cases a body protection is not required.

Respiratory protection:

      Respiratory protection necessary if insufficient ventilation.

      Self-contained respirator (DIN EN 133) or container device with compressed air (DIN EN 137).

      Filtering device (full mask or mouthpiece) with filter A (EN 14387).

Environmental exposure controls:

      Do not allow to enter drains/surface water/ground-water.

      Do not allow to enter into soil/subsoil.

Stability and reactivity

No hazardous reaction or decomposition if stored and handled as prescribed.

At reduced pressure may be distilled without decomposition.

Avoid contact with concentrated alkaline compounds and/or strong oxidizing agents.
