Matthew Langenfeld

Matthew Langenfeld holds a Masters in Chemistry from the South Dakota School of Mines and Technology. An environmental professional for 29 years, he has worked in industry and consulted with state and federal governments. He instructed college chemistry laboratory courses and has worked on school chemical cleanout and safety issues with the U.S. Environmental Protection Agency for nearly 6 yea. During that time, he has helped develop school chemical cleanout programs in Montana, Wyoming, Colorado and South Dakota. His accomplishments include the cleanout of 123,000 pounds of toxic chemicals from 267--88 of these in Indian Country--making schools safer for 96,000 school children.

PCBs in Ballasts & Caulk

Polychlorinated Biphenyls

Goal

Tribal school administrators, teachers, including science and trades teachers, health and safety coordinators, and facilities personnel will become aware of the danger of PCBs and will be committed to and have tools for assuring clean, green and healthy schools for themselves, children and their community.

slide4

PCBs in Ballasts & Caulk

Polychlorinated Biphenyls

Do we know all the places where PCBs may be hiding and why they are a health concern in our schools?

What can we do about PCBs?

slide5

PCBs in Ballasts & Caulk

Polychlorinated Biphenyl

  • The Problem?
  • PCBs can be found in
  • schools

Exposure to PCBs can result

in health problems, inclu-

ding increased risk of cancer,

immune, reproductive or

nervous system difficulties

slide6

PCBs in Ballasts & Caulk

Polychlorinated Biphenyls

Out of sight, out of mind

Humans are exposed to

PCBs through breathing,

eating, and physical

contact

Polychlorinated Biphenyl Molecule

slide7

PCBs in Ballasts & Caulk

Polychlorinated Biphenyls

Children are more vulnerable

to dangerous effects of PCBs

PCBs can exist as a vapor in the air, have no smell or taste

PCBs can attach to organic particles, bind to the soil and then be taken up by humans and animals

slide8

PCBs in Ballasts & Caulk

Polychlorinated Biphenyls

The major source of human

PCB exposure is from

eating contaminated

fish.

slide9

PCBs in Ballasts & Caulk

Polychlorinated Biphenyls

PCBs get into the food chain

and bioaccumulate

  • They are fat/water soluable

FDA has issued guidelines for

tolerance levels of PCBs in

fish meat

milk eggs soap

food packaging

slide10

PCBs in Ballasts & Caulk

Polychlorinated Biphenyls

PCBs enter and

biomagnify in

the food chain

slide11

PCBs in Ballasts & Caulk

Polychlorinated Biphenyls

  • PCBs are found in caulk in schools renovated
  • between 1950 and 1978

PCBs can be found in flourescent light ballasts

manufactured before 1979

Removal and replacement can be a major and

expensive undertaking

slide12

PCBs in Ballasts & Caulk

Polychlorinated Biphenyls

  • PCBs in caulk can migrate to
  • Adjoining materials
slide13

PCBs in Ballasts & Caulk

Polychlorinated Biphenyl

If known, caulk with PCBs >/= 50 ppm Is illegal and should be removed

Contaminated adjoining

materials >/= 1 ppm should be removed

Caulk with PCBs < 50 ppm

may remain in place

slide14

PCBs in Ballasts & Caulk

Polychlorinated Biphenyls

PCBs in caulk can be detected by:

Laboratory tests of samples

slide15

PCBs in Ballasts & Caulk

Polychlorinated Biphenyls

Immediate steps to reduce exposure:

Clean air ducts

Improve ventilation

Clean frequently to reduce dust

Clean surfaces with a wet or damp cloth

Don’t use brooms or dusters

Use vacuums with high efficiency particulate

filters (HEPA)

slide16

PCBs in Ballasts & Caulk

Polychlorinated Biphenyls

It may be commons sense, but:

Do not allow removed caulk to remain in the

school or on the school grounds

Caulk with < 50 ppm does not have to be re-

moved, but may still pose a health hazard

slide17

PCBs in Ballasts & Caulk

Polychlorinated Biphenyl

Fluorescent Light Ballasts

Removal best done by

the pros

Dispose by PCB

regulations

slide18

PCBs in Ballasts & Caulk

Polychlorinated Biphenyls

Be aware of regulations:

“ … disposers of fluorescent light ballasts

that contain a PCB small capacitor should be

aware that they could be subject to CERCLA

liability if the municipal solid waste landfill

becomes a Superfund site.”

(This will also apply to caulk

containing PCBs)

63 Fed. Reg 35383, 35404 06.29.98

Carbonless copy paper

Transformers

Capacitors
