What Are Safe Limits for Tetrachloroethane Testing?

Q: What Are Safe Limits for Tetrachloroethane Testing?

A:

1. What is tetrachloroethane and what are its dangers?

Tetrachloroethane, also known as perchloroethylene or PCE, is a colorless and nonflammable liquid commonly used as a dry cleaning solvent and degreaser. Prolonged exposure to tetrachloroethane through inhalation or skin contact can cause health problems like liver and kidney damage, neurological symptoms, and even cancer.

2. How is tetrachloroethane exposure measured?

Tetrachloroethane exposure is typically measured through air monitoring or biological monitoring. Air monitoring involves collecting air samples from the workplace or other areas where tetrachloroethane is present and analyzing them in a laboratory. Biological monitoring involves testing biological specimens like blood or urine to determine the levels of tetrachloroethane metabolites in the body.

3. What are the safe limits for tetrachloroethane exposure?

The safe limits for tetrachloroethane exposure vary depending on the specific context and the country or region where testing is being conducted. In the United States, the Occupational Safety and Health Administration (OSHA) has established a permissible exposure limit (PEL) for tetrachloroethane of 100 parts per million (ppm) over an eight-hour workday. The National Institute for Occupational Safety and Health (NIOSH) recommends a lower PEL of 25 ppm over an eight-hour workday. The Environmental Protection Agency (EPA) has set a reference concentration for tetrachloroethane of 0.03 ppm in the air for long-term exposure.

Overall, it is important to monitor tetrachloroethane exposure levels to ensure that they are below safe limits and to take steps to reduce or eliminate exposure if necessary. This may include using protective equipment like respirators or gloves, improving ventilation in the workplace, or switching to alternative cleaning or degreasing methods that are less hazardous.
