What do PCBs look like?

Polychlorinated biphenyls (PCBs) are a group of manmade chemicals. They are oily liquids or solids, clear to yellow in color, with no smell or taste. PCBs are very stable mixtures that are resistant to extreme temperature and pressure. PCBs were used widely in electrical equipment like capacitors and transformers.

What are some examples of PCBs?

Products that may contain PCBs include:
  • Transformers and capacitors.
  • Electrical equipment including voltage regulators, switches, re-closers, bushings, and electromagnets.
  • Oil used in motors and hydraulic systems.
  • Old electrical devices or appliances containing PCB capacitors.
  • Fluorescent light ballasts.
  • Cable insulation.

Are PCBs still used today?

Unfortunately, the legacy of PCBs for humans, birds, fish, wildlife, and habitat has been a lasting one. As NOAA's National Ocean Service notes: Even with discontinued use, PCBs, or polychlorinated biphenyls, are still present in the environment today because they do not breakdown quickly.

Are PCBs harmful to humans?

PCBs are a probable human carcinogen.

Studies of PCBs in humans have found increased rates of melanomas, liver cancer, gall bladder cancer, biliary tract cancer, gastrointestinal tract cancer, and brain cancer, and may be linked to breast cancer.

What do PCBs smell like?

PCBs are a group of man-made chemicals consisting of 209 individual compounds of a similar chemical structure. They are either oily liquids or solids with no smell or taste.

What does PCB mean in texting?

What does PCB oil smell like?

PCBs have no known taste or smell, and range in consistency from an oil to a waxy solid. PCBs belong to a broad family of man-made organic chemicals known as chlorinated hydrocarbons. PCBs were domestically manufactured from 1929 until manufacturing was banned in 1979.

Is it OK to touch a PCB?

The non conductive substrate is completely safe and is usually the green or blue bit of the PCB. However starting to touch some of the components on it, for example a capacitor or resistor could have fatal consequences, (to the board) as they do conduct electricity and with a very very small voltage) with short out.

What happens if you touch PCB?

PCB exposure may also cause abnormal liver tests or an enlarged liver in some individuals. PCBs can cause reproductive and hormonal effects, and, in exposed children, developmental, immunological and neurological effects. Data strongly suggests that long term overexposure may cause cancer.

Are circuit boards toxic?

Burning the plastic-metal mix in printed circuit boards releases toxic compounds such as dioxins and furans. In landfills, the metals on the boards can eventually contaminate groundwater.

Can you bend a circuit board?

All types of circuit boards have the same basic theory for bending, forming and flexing. However the circuit board construction and the materials used, will limit which type of board can feasibly be bent, formed or flexed. Normally woven glass reinforced circuit boards cannot be bent, formed or flexed reliably.
