Reaction mass of divinylbenzene and ethylstyrene

Guidance on Safe Use

First-aid measures

Eye Contact: Flush eyes thoroughly with water for several minutes.  Remove contact lenses after the initial 1-2 minutes and continue flushing for several additional minutes.  If effects occur, consult a physician, preferably an ophthalmologist.

Skin Contact: Remove material from skin immediately by washing with soap and plenty of water.  Remove contaminated clothing and shoes while washing.  Seek medical attention if irritation persists. Wash clothing before reuse.  Discard items which cannot be decontaminated, including leather articles such as shoes, belts and watchbands.  

Inhalation: Move person to fresh air.  If not breathing, give artificial respiration; if by mouth to mouth use rescuer protection (pocket mask, etc).  If breathing is difficult, oxygen should be administered by qualified personnel.  Call a physician or transport to a medical facility.  

Ingestion: Do not induce vomiting. Call a physician and/or transport to emergency facility immediately.  

Notes to Physician: Maintain adequate ventilation and oxygenation of the patient.  May cause asthma-like (reactive airways) symptoms.  Bronchodilators, expectorants, antitussives and corticosteroids may be of help.  Because rapid absorption may occur through the lungs if aspirated and cause systemic effects, the decision of whether to induce vomiting or not should be made by a physician.  If lavage is performed, suggest endotracheal and/or esophageal control.  Danger from lung aspiration must be weighed against toxicity when considering emptying the stomach.  If burn is present, treat as any thermal burn, after decontamination.  No specific antidote.  Treatment of exposure should be directed at the control of symptoms and the clinical condition of the patient.  

Medical Conditions Aggravated by Exposure: Excessive exposure may aggravate preexisting asthma and other respiratory disorders (e.g. emphysema, bronchitis, reactive airways dysfunction syndrome).  

Emergency Personnel Protection: First Aid responders should pay attention to self-protection and use the recommended protective clothing (chemical resistant gloves, splash protection).  If potential for exposure exists refer to Section 8 for specific personal protective equipment.

Fire-fighting measures

Extinguishing Media: Water fog or fine spray.  Dry chemical fire extinguishers.  Carbon dioxide fire extinguishers.  Foam.  General purpose synthetic foams (including AFFF type) or protein foams are preferred if available.  Alcohol resistant foams (ATC type) may function.  

Fire Fighting Procedures: Keep people away.  Isolate fire and deny unnecessary entry.  Use water spray to cool fire exposed containers and fire affected zone until fire is out and danger of reignition has passed.  Fight fire from protected location or safe distance. Consider the use of unmanned hose holders or monitor nozzles.  Do not use direct water stream.  May spread fire.  Burning liquids may be moved by flushing with water to protect personnel and minimize property damage.  Avoid accumulation of water.  Product may be carried across water surface spreading fire or contacting an ignition source.  Contain fire water run-off if possible. Fire water run-off, if not contained, may cause environmental damage.  Review the "Accidental Release Measures" and the "Ecological Information" sections of this (M)SDS.  

Special Protective Equipment for Firefighters: Wear positive-pressure self-contained breathing apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat, trousers, boots, and gloves).  Avoid contact with this material during fire fighting operations. If contact is likely, change to full chemical resistant fire fighting clothing with self-contained breathing apparatus.  If this is not available, wear full chemical resistant clothing with self-contained breathing apparatus and fight fire from a remote location.  For protective equipment in post-fire or non-fire clean-up situations, refer to the relevant sections.

Unusual Fire and Explosion Hazards: Container may rupture from polymerization.  Violent steam generation or eruption may occur upon application of direct water stream to hot liquids.  Dense smoke is produced when product burns.  

Hazardous Combustion Products: During a fire, smoke may contain the original material in addition to combustion products of varying composition which may be toxic and/or irritating.  Combustion products may include and are not limited to:  Carbon monoxide.  Carbon dioxide.

Accidental release measures

Steps to be Taken if Material is Released or Spilled: Small spills:  Absorb with materials such as:  Sand.  Imbiber Beads®.  Do NOT use absorbent materials such as:  Clay.  Vermiculite.  Zorb-all®.  Large spills:  Dike area to contain spill.  See Section 13, Disposal Considerations, for additional information.  

Personal Precautions: Isolate area.  Keep upwind of spill.  Keep unnecessary and unprotected personnel from entering the area.  Ventilate area of leak or spill.  No smoking in area.  Refer to Section 7, Handling, for additional precautionary measures.  Use appropriate safety equipment. For additional information, refer to Section 8, Exposure Controls and Personal Protection.  

Environmental Precautions: Prevent from entering into soil, ditches, sewers, waterways and/or groundwater. See Section 12, Ecological Information.

Handling and storage

Handling

General Handling: Avoid contact with eyes.  Avoid contact with skin and clothing.  Do not swallow.  Avoid breathing vapor.  Wash thoroughly after handling.  Keep container closed.  Use with adequate ventilation.  Keep away from heat, sparks and flame.  Containers, even those that have been emptied, can contain vapors. Do not cut, drill, grind, weld, or perform similar operations on or near empty containers.  See Section 8, EXPOSURE CONTROLS AND PERSONAL PROTECTION.  

Storage

Maintain inhibitor and dissolved oxygen level. Do not purge containers of this material with nitrogen.  Uninhibited monomer vapors can polymerize and plug relief devices.  Store in a dry place.  Store away from direct sunlight.  Keep away from high temperatures and hot pipes.  Ask for a product brochure.  See Section 10 for more specific information.  The shelf-life of stored divinylbenzene can be extended with timely aeration.  A 5-10 minute air sparge is recommended on a monthly basis for drums & pails stored at temperatures between 21-27°C.  Divinylbenzene containers stored at temperatures from 4-21°C need to be aerated according to the table below. With aeration and maintenance of p-tert butylcatechol (TBC) levels above 400-600 ppm the clock is effectively reset to the recommended storage times.  

Storage Period:                       Storage temperature:             Aerate within:
