Emergency Treatment Of Accidental Encounter With Styrene

Jul 27, 2020

Everyone knows that styrene is a harmful liquid. Once improperly handled, it will cause unimaginable consequences. After reading this article, you don’t have to panic when encountering styrene. The editor below integrates some emergency measures for styrene. 

1. Styrene first aid measures

   Skin contact: Take off contaminated clothing, and rinse the skin thoroughly with soap and water.

   Eye contact: Immediately lift the eyelids and rinse thoroughly with plenty of running water or saline for at least 15 minutes. Seek medical attention.

   Inhalation: Leave the scene quickly to a place with fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.

   Ingestion: Drink enough warm water to induce vomiting. Seek medical attention.

2. Styrene fire protection measures

   Hazardous characteristics: Its vapor and air can form an explosive mixture, which may cause combustion and explosion when exposed to open flames, high heat or contact with oxidants. When encountering acidic catalysts such as Lewis catalysts, Ziegler catalysts, sulfuric acid, ferric chloride, aluminum chloride, etc., it can polymerize violently and release a lot of heat. Its vapor is heavier than air and can spread to a considerable distance in a lower place, and will ignite when it encounters a fire source.

   Hazardous combustion products: carbon monoxide, carbon dioxide.

  Extinguishing method: Move the container from the fire scene to an open place as much as possible. Keep the fire container cool by spraying water until the fire is over. Extinguishing agent: foam, dry powder, carbon dioxide, sandy soil. Extinguishing with water is ineffective. In the event of a big fire, firefighters must operate in protective shelters.

3. Emergency treatment of styrene leakage

  Emergency treatment: Quickly evacuate personnel from the contaminated area to a safe area, isolate them, and strictly restrict access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure respirators and anti-virus suits. Cut off the source of leakage as much as possible. Prevent inflow into restricted spaces such as sewers and flood drains.

  Small leakage: absorb with activated carbon or other inert materials. It can also be scrubbed with an emulsion made of incombustible dispersant, and the lotion is diluted and put into the waste water system.

   A large number of leaks: construct dikes or dig pits for storage. Cover with foam to reduce steam hazards. Use explosion-proof pump to transfer to tanker or special collector, recycle or transport to waste disposal site for disposal.
