Why use a perchloroethylene sensor?
Perchloroethylene gas (C2CL4), which is also sometimes referred to as Tetrachloroethylene, is a colorless liquid commonly used in dry cleaning of fabrics and metal degreasing applications in metalworking industries. The liquid readily evaporates into the air and can be toxic to humans if inhaled. Health problems from exposure include headaches, irritation and neurological damage. Long term exposure can also result in various cancers forming in the body.
Dry Cleaning and Laundry Applications
Perchloroethylene is an effective chemical solvent used to dry clean clothes. Modern dry cleaning practices have resulted in a significant decrease in the concentration of perchloroethylene being used. However, due to the negative health effects caused by long term exposure, control and monitoring of perchloroethylene is still very important in order to keep the employees safe in these environments. Monitoring is often performed to determine personal exposure levels, identify leaks and measure changes in perchloroethylene levels after service and maintenance to equipment. Aeroqual can provide both fixed and portable monitors with a perchloroethylene sensor to measure real time concentrations and trigger alarms when health and safety levels are exceeded.
Degreasing of Metals
Perchloroethylene is also widely used to remove oil and oil-borne contaminants from objects that have undergone processes such as machining, welding and soldering. Modern vapor degreasing techniques have become common practice in the automotive and electronic manufacturing industries. Like within the dry cleaning industry, ensuring perchloroethylene concentrations are kept at safe levels to reduce human exposure is very important.
