Sins of the past

Sins of the past, can become problems of the future

The company along are built up a not inconsiderable experience in consulting and management of “sins of the past”

Scanbau Ltd. offers all kinds of studies, test, udarbejdelser of omfangs descriptions / reports, the drafting of the tender descriptions, identification of suitable contractors, all superintendence, command, control, etc.

These are the following;

PCBs were used in the construction of about 1950 - 1977, and chlorinated paraffins especially in the period after 1977 replaced the PCB. PCB has had widespread use in construction until the 1977th.

PCBs as additives in sealants is probably the most famous example, but PCB is also used in paints, double glazing and as an additive in building materials.

PCBs may pose a problem for both the indoor climate and working environment, external environment and waste in renovation projects if not handled properly in the execution phase.

Proper handling requires, first, that there is a comprehensive feasibility study, a thorough planning, work coordination and supply material that describes all requirements for the bidding contractors.

An inadequate supply can have very substantial consequences for delays and budget for the project, not least unintended risk of indoor air quality problems in the subsequent use of the building.

Facts on PCB

PCB is one of the 12 most dangerous pollutants and is therefore highly undesirable in the environment. PCB migrates into adjacent buildings and the air, and by exposure through contact and inhalation accumulate in the body.

PCB in large quantities can result in long-term exposure, cause damage to the immune system, nervous system, liver, thyroid, increasing the risk of diabetes and can affect fertility. In addition, PCB increase the risk of cancer.

PCB is in the maximum levels for both the working environment, external environment and the indoor climate. In residential buildings medical officer may require the implementation of an action plan to reduce PCBs in indoor air.

Chlorinated paraffins are also a dangerous pollutant. Chlorinated paraffins will not normally give rise to problems in the indoor environment for a renovation project.

LEAD - as the above.

Asbestos - as the above.

"When you reorganize, renovate and tear down, employees can be exposed to chemical substances and products that are so hazardous that it is forbidden to use them today."

We meet sins of the past in building materials or hazardous waste is buried.

This may include:

  • Asbestos
  • PCB
  • Lead
  • Tar
  • Contaminated soil
  • Impregnated wood

In the planning phase requires special attention to examine whether there are hazardous materials.

During the work itself may be required extra security measures to protect artisans and possible. users of the buildings.

It will often be necessary in the beginning of the work period to dispose of hazardous waste (special disposal).
