CPVC:When You Need High Performances

The main benefits of CPVCMain performance improvements brought by the use of CPVC for water pipeworks:

⇒ Resistance to chlorine based water treatments

⇒ Resistance to high temperatures

⇒ Higher mechanical rigidity

⇒ Less thermal movements

⇒ Non flammable (M1 / B)

⇒ No smoke emissions (s1)

⇒ No flaming drips (d0)

⇒ Thermoforming possible for fabrication

⇒ Welded system integrity & durability of joints

⇒ Non permeability to gases

⇒ Potable water approved

A high quality material, featuring manyadvantages against alternative solutions

HUMAN LIVES ARE AT STAKE

Le Figaro, 1st Sept. 2009

An epidemic of Legionella was declared in European Hospital Georges Pompidou in Paris shortly after its inauguration.A total of 11 patients had been contaminated in December 2000 & June 2001. Five of them died, but without any legal action being takenafterwards. Today, French national newspaper Le Figaroreports from reliable legal sources that the Paris Board of Hospitals (APHP) is to be prosecutedon the grounds of manslaughter, characterisedfaults, endangering human lives. In their report to the judges, experts stated thatAPHP had made wrong decisions concerning thedomestic water services installation. Experts mentionned that APHP had not takenspecialist advice into account concerning thechoice of materials for that installation. It wasclearly established that selecting galvanisedsteel pipeworks caused the infection, further to erosion of pipes in contact with hot water.

Enquiry concerning 3 cases of legionella infection in a Dubai hotel.

DUBAI, U.A.E. – on Sunday 1st February, the HQ of a 5 star Dubaihotel announced that they would collaborate with local authorities in order to determine the origin of 3 cases of legionella infection detected in their hotel. One of the victims died last Friday.

Starwood Hotels & Resorts Worldwide explained that they werecarrying out investigations in collaboration with governmentalhealth services and had called for advice from European andAmerican specialists.

Starwood reported that legionella had been detected for 3 clients. One of them, of British nationality, died at 69 years of age. TheBritish press reported that he was thought to be suffering from fluwhen he returned home on 20th January. However, his state ofhealth deteriorated and he died in Swindon hospital a few days later.

WATER QUALITY: CORROSIONCorrosion leads to:• Proliferation of micro-organisms in thedeposits which build up inside pipeworks

• Deterioration of the installation impairs itsability to fulfill its function: leaks, coloration 10 year guarantee // particles water conformity?

• Inactivation of disinfectants by reduction ofoxydating agents such as chlorine

Guide P. 50

WATER QUALITY: CORROSIONCopper corrosion can be caused by :• erosion if v>1.5m/s (e.g. change ofcirculation pump)• bad resistance to chemical treatments & water t°>60°C, • nature of the water pitting 1 appearswith high mineralisation CWS, pitting 2 appears with low mineralisation HWS +pH<7.4

WATER QUALITY: SCALEScale leads to:• Obstruction of pipeworks

• Bacteria development

• Reduced thermal transportation capacities

• Scale build up increases with water temperature

PSEUDOMONA AERUGOSINAPseudomonas Aeruginosa (PA) is frequently responsible for severenosocomial infections. PA infections need to be reported to Health Authorities especially in case of patient fatalities.

Report analysis between 08/2001 and 06/2006 confirms theimportance & severity of PA nosocomial infections. Out of 332 cases reported, PA infections caused 122 fatalities (9%).74% of the cases reported originated from nosocomial infections.

« PA related nosocomial infections show extremely high resistancelevels to treatments and high proportions of totally resistant bacteriagroups »
