Polychlorinated biphenyls (PCBs) are synthetic organic chemicals that were once widely used for their insulating and non-flammable properties. Unfortunately, PCBs can pose significant dangers in the workplace, particularly in industries where older electrical equipment, hydraulic systems, caulking, or fluorescent lighting ballasts are still in use.
Although their manufacture was banned in the United States in 1979, equipment containing PCBs can still be found in some older facilities. Workers who handle or maintain this equipment risk exposure through inhalation of contaminated air, skin contact, or accidental ingestion of PCB-laden dust or oil.
PCBs are classified as probable human carcinogens and have been linked to various types of cancer, including liver and skin cancers. In addition to carcinogenic effects, PCBs can cause a wide range of non-cancer health issues such as liver damage, reproductive disorders, immune system suppression, and endocrine disruption. Long-term or repeated exposure can also lead to neurological effects, particularly in workers who may not use adequate protective equipment or who are unaware of the contamination risks in their environment.
“Employers have a legal responsibility to protect workers from exposure to PCBs,” said Joe Frasca, Senior Vice President of Marketing at EMSL Analytical, Inc. “This includes identifying and labeling PCB-containing materials, training employees on the risks, and providing appropriate personal protective equipment. Facilities must also follow regulatory guidelines for the proper disposal and cleanup of PCB-containing materials, as improper handling can lead to environmental contamination in addition to human health risks.”
To help identify these types of potential hazards and to keep employers in regulatory compliance, EMSL Analytical provides industrial hygiene, material, environmental, and indoor air quality testing services and sampling supplies for PCBs and many other chemical substances. They also offer a wide range of personal protective equipment (PPE). Several years ago, EMSL even sponsored an educational video about PCBs in building materials that can still be seen at: https://youtu.be/o-e5o86u0mk
