1,1,2,2-Tetrachloroethane Work

Health Hazards

Acute:
Inhalation: Vapors can cause nausea, vomiting, weight loss, anemia, and sometimes fatal liver damage. Severe exposure can damage the peripheral nervous system, with typical symptoms such as loss of sensation, tingling in the fingers and toes, and central nervous system symptoms like depression, loss of consciousness, pulmonary edema, and kidney damage.
Skin: Absorption through the skin can cause symptoms similar to inhalation or ingestion (which may be fatal).
Eyes: Causes irritation.
Ingestion: Suppresses the central nervous system, causing dizziness, loss of consciousness, and liver damage. Even a small amount (5ml) can be fatal.

Chronic:
Damages the peripheral nervous system, liver, and central nervous system.
Liver disease: Fatty degeneration of the liver (cirrhosis), gangrene (cell death), and atrophy.
Increased white blood cells in the blood. People with liver disease are more susceptible to harm.

Suggestions:
Level 1 Management: No specific regulations.
Level 2-4 Management:
Consider health conditions unsuitable for this type of work, such as neurological disorders, liver disease, and kidney disease.
