Watch out for PCBs (POLYCHLORINATED BIPHENYLS)

Watch out for Asbestos

Watch out for Lead Paint.

Watch out for …………………..

PCBs are mixtures of up to 209 individual chlorinated organic compounds. Due to their valuable technical qualities (softeners that make sealants easier to apply and extend their durability) they have been used since 1929 and since used as a compound is many forms of insulation within Buildings (as well as being used in coolant systems, grouting and plasticisers in paint).

Since the 1970’s we now know that such PCBs have real Health & Safety risks associated with them: Environmental and Human health risks as they are very difficult to dispose of safely. PCBs have multiple ways of causing long term human health problems – one of the reasons that the Government introduced regulations that don’t allow us to simply take an unwanted refridgerator down to the local Tip.

PCBs will pass straight your skin and fibres will easily be breathed in if they are released into the air.

In Sweden, the use of PCBs was banned in 1972, with minor exceptions. A total prohition was later introduced in 1995. Home owners in Sweden are under a legal duty to audit their homes and decontaminate PCBs in all types of building erected between 1956 and 1973. This means that owners must arrange for inspection and testing using specific reporting templates. Each Buildings’ template should have been submitted to a Supervisory Authority before 30th June 2008 if an Injunction was not to be served on them (to perform that inspection and audit process and/or receive a later Fine).

PCBs in Sweden were used in Building elements such as compounds to seal movement-joints, flooring compounds, window seals and electrical capacitors (including in many fluorescent lights). PCBs are often found is fascade joints, around window and door frames, hidden underneath door thresholds, balcony junction seals, floor finishes/tiles, seals within double glazing units.

Surveyors would typically need to use gloves, protective glasses, breathing–filters etc… and any tools used to expose risk areas/element would have to be cleaned with acetone.

Early surveys revealed that PCBs had contaminated other materials in close contact and remedial works would be more extensive than at first expected.

The decontamination works have a legal deadline phased until 2013.

IN ENGLAND WE HAVE SIMILAR BUILDINGS AND SIMILAR PROBLEMS BUT WE HAVE NOT TAKEN SUCH STRINGENT ACTIONS AS IN SWEDEN.
However, we do take Health & Safety seriously and the following regulate PCBs

• The Health & Safety at Work etc Act 1974
• The Control of Substances Hazardous to Health Regulations 1994
• The Environmental Protection Act 1990

So: how can a House Surveyor help you identify and reduce these risks?

Let me be blunt – a Surveyor undertaking an ordinary home inspection, even a full Building Survey, will not be completing the degree of forensic inspection required to report meaningfully on such issues. PCB building inspections are a very specialist area of expertise, similar to Asbestos or Lead Paint Surveying, and should be arranged as an extra precautionary measure in advance of your property transactions.

In respect of identifying lead paint this is not as easy as you would first think.  Approximately 70% of UK Buildings pre-date 1970 – abt 18.5 million homes and thousands of public, school and workplace buildings – and many will have had lead-based-paint systems at sometime in their history. The problem is that if where all paint has been stripped away much of the lead will have migrated into the sub-strate (often timber) awaiting later dispersal.

In respect of asbestos PROinspect remind you that although some asbestos-containing-materials (ACMs) are “obvious” to visual means of inspection most ACMs are embedded or screened from viewing. This means that detection is a hit-and-miss affair.

Like a lot of surveying, it is the experience of the Surveyor that is the key factor. Don’t expect a Loan Valuer to identify such problems, don’t expect most House Surveyors to identify such issues. Chose your Experts wisely and after due diligence – TALK TO ACTUAL SURVEYORS (not an intermediatory or secretary) TO GET ADVICE.

And finally …….

1. Knight Frank research suggests 2010 will see house prices, nationally, fall 2%.
2. Planning Application for 800 ECO Homes at Newport, IOW, has been submitted. All heating will be supplied by a Biomass centre.
3. The UK is currently producing enough electricity from wind power to serve 2.3m homes.

The lesson to be learnt is TAKE ADVICE before you commit to any property transaction, preferably from an experienced Surveyor. If you are in southern England call me or use the CONTACT FORM above. Stuart Parrett +44 (0)1489 897 164.
