When converting roofs in old buildings, there is a risk of wood preservatives being contaminated by toxic paints, which are now banned. These highly contaminated wood preservatives were not only used in the roof area and for the exterior. They are not only used in the rooms for which they were intended, but also indoors to paint beams, wooden floors, wooden panels or cladding. They are particularly dangerous to the health of the occupants as they can continue to emit pollutants for decades.

Wood preservatives with PCP and lindane
Wood preservatives containing the hazardous substances PCP and lindane were mainly used in the 1960s and 1970s to protect roof beams and even wooden toys. These are highly volatile pollutants (SVOCs) that can continue to outgas indoors for decades and accumulate in house dust, causing health problems and even cancer.
Avoid pollutants from building materials in new buildings
Pollutants from building materials can cause considerable damage to the environment. Rainwater from parts of the building can enter the surface water from the new building. A recent study commissioned by the Federal Environment Agency (UBA) found high levels of pollutants in two new development areas. However, these can be avoided during new construction. It was also investigated how the release of pollutants into the environment can be reduced.
Measuring cooling lubricants
Measure hazardous cooling lubricants with SG5200 and SG100ex measuring devices
Our SG5200 or SG5100ex samplers can be used to check for possible hazards caused by lubricants. These measuring devices for measuring cooling lubricants are coupled with the GGP sampling system and can, for example, detect oil aerosols and measure cooling lubricants.
If you have any questions about measuring hazardous cooling lubricants or the measuring devices, our staff will be happy to help.
What are cooling lubricants?
Definition
Cooling lubricant is a collective term for mixtures of substances that are used in metalworking for cooling and lubrication. It is often a multi-component mixture, as the basic substances – water and oil – alone do not have the desired effect. There are two main effects:
- Cooling: Lowering the temperature caused by friction
- Lubrication: Reduction of friction between tool and workpiece
