4. How does Sodium aluminium hydride affect workers?
Sodium aluminium hydride (NaAlH4) is a chemical with strong chemical properties, and exposure to it can significantly affect the health of workers. The toxic nature of sodium aluminium hydride mainly stems from its ability to react strongly with water and release hydrogen gas, as well as compounds that can be harmful to the body.
When workers come into direct contact with sodium aluminium hydride, there is a risk of serious health problems. Dust or vapors from sodium aluminium hydride can cause irritation to the respiratory system. Symptoms of exposure include coughing, difficulty breathing, and respiratory irritation. In more severe cases, it can lead to pneumonia or long-term respiratory problems if not treated promptly.
Contact with sodium aluminium hydride can also cause skin and eye irritation. This chemical can dry out the skin and cause allergic reactions such as rashes or itching. When it comes into contact with the eyes, sodium aluminium hydride can cause redness, pain, and in some cases, serious eye damage.
Furthermore, sodium aluminium hydride can cause digestive problems if ingested. It can cause nausea, abdominal pain, and in serious situations, can lead to stomach or intestinal damage. Therefore, ensuring proper preventive measures is very important to avoid these health problems.
To minimize risks, workers need to be fully trained on how to handle sodium aluminium hydride safely. This includes using personal protective equipment such as gloves, masks, and safety glasses, as well as implementing preventive measures to avoid direct contact with the chemical.
