4. How does Methylphenyl dichlorosilane affect workers?
Methylphenyl dichlorosilane, although an important chemical in many industrial production processes, also poses health risks to workers upon long-term or improper exposure. This chemical can seriously affect worker health through various routes of exposure, including inhalation, skin contact, and ingestion.
When inhaling the vapor or dust of Methylphenyl dichlorosilane, workers may experience respiratory problems. Symptoms can include coughing, difficulty breathing, and respiratory tract irritation. If exposure is prolonged, this chemical can cause pneumonia and more serious respiratory diseases. Inhaling a large amount of the chemical in a short time can also lead to bronchospasm, causing difficulty in breathing.
Direct contact with skin and eyes can also cause serious health problems. Methylphenyl dichlorosilane can cause skin irritation, leading to redness, itching, and inflammation. For the eyes, this chemical can cause eye pain, redness, and in severe cases, can cause eye damage and vision loss. If not treated promptly, these problems can become serious and cause long-term health effects.
In addition, if Methylphenyl dichlorosilane is accidentally swallowed, it can cause digestive symptoms such as nausea, vomiting, and abdominal pain. This chemical can also cause damage to the digestive system and internal organs if exposed at high levels or for a long time.
