Carbon Tetrachloride Work

Health Hazards

Acute:
Inhalation:
1.1 Affects the central nervous system and damages the liver and kidneys.
1.2 Exposure to 20 ppm for 8 hours can cause headaches, dizziness, nausea, and loss of coordination.
1.3 Repeated daily exposure to 200 ppm for 8 hours over several weeks or months can damage the liver and kidneys.
1.4 Exposure to 250 ppm for 15 minutes can be fatal to sensitive individuals (such as heavy drinkers).
1.5 Kidney damage from exposure may lead to pulmonary edema 8 days later.

Skin:
2.1 Causes a burning sensation and slight redness.
2.2 Rapid skin absorption can cause nausea, vomiting, and liver and kidney damage.
Eyes: Vapors and liquids mildly irritate the eyes and may cause vision damage.

Ingestion:
4.1 As little as 1.5 ml can be fatal; the commonly fatal dose is between 50-150 ml.
4.2 Symptoms are similar to inhalation and can irritate the stomach.

Chronic:
Repeated exposure may cause severe liver and kidney damage, heart and lung weakness, and nervous system damage.
Suspected carcinogen, causing liver tumors in animals, though data on humans is limited.
Alcohol, barbiturates, pesticides, and halogens can enhance its toxicity, while carbon disulfide can reduce its toxicity.

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