EVERYONE seems to know a friend or loved one with cancer these days. Some experts say we must change our lifestyles to prevent it while others claim it is simply a disease of the modern world.

Article taken from the Daily Express - 4/11/10 http://www.express.co.uk/posts/view/209444


Almost every day another name gets added to that most unpopular of roll calls: the celebrity cancer register. This week presenter Danny Baker joined actors Michael Douglas, the late Simon McCorkindale and Jennifer Saunders in one of the West’s least exclusive clubs. Other victims include celebrities who are surely among the fittest in their age group, such as tennis legend Martina Navratilova and Kylie Minogue.

Professor Rosalie David at the university said: “In industrialised societies cancer is second only to cardiovascular disease as a cause of death. But in ancient times it was extremely rare. There is really nothing in the natural environment that can cause cancer so it has to be a man-made disease, down to pollution and changes to our diet
and lifestyle.”

However Cancer Research UK disputes claims that cancer was unknown in the Ancient World and cites several natural causes of the disease. UV radiation from the sun, bacteria, viruses and the radio- active gas radon are as natural as breathing and all linked to cancer.

Even here man’s influence may be at play. Cases of the most dan- gerous form of skin cancer, malignant melanoma, have more than quadrupled over the past 30 years in Britain. This is almost certainly because package holidays have let us worship the sun in droves in climates too extreme for our sensitive northern skins. What has also changed in recent years is the weakening of Earth’s natural protection against UV radiation, the ozone layer, thanks to damage from man-made chemicals.

Cancer Research UK says that lifestyle factors – smoking, drinking and obesity – all add to the cancer risk. But again alcohol is far from new. Britons have been boozing for centuries. It’s what we’re good at. And a visit to a cancer clinic does not reveal a gaggle of Teletubbies of whom you could say: “You ate too many pies. You drank too many pints. It’s your own stupid fault.”

I don’t pretend to know why there is a surge in cancer rates.  Greater minds than mine have yet to find a clear answer. Obviously we are living longer and in the West detection rates are dramatically better than when I was a child. But that surely cannot explain the doubling and trebling over such a short period of these cancers. You have to wonder whether there is something in the air we breathe, the water we drink or the food we eat. Is that panoply of must-have electric gizmos having unforeseen effects? Are modern lives now so stressful that our bodies are rebelling?

One of the prime suspects has to be the huge battery of chemicals in daily use. In 2005 scores of scientists from across Europe put their names to the Prague Declaration to express their concerns about exposure to hormone disrupting or gender-bending chemicals. They said: “The incidence of cancers such as breast, testis and prostate continues to increase in many European countries, although there are notable differences between countries... This shows that these cancers are linked to factors in the environment, including the diet.”

In 2006 the European Commission said long-term exposure to pesticides can lead to “serious disturbances to the immune system, sexual disorders, cancers, sterility, birth defects, damage to the nervous system and genetic damage”.

Yet the chemicals industry had to be dragged kicking and screaming into the EU’s agreement on the Registration and Evaluation, Authorisation and Restriction of Chemicals. And veteran campaigner Georgina Downs is still battling for rural residents to be given the right to be told which chemicals are being sprayed on nearby fields and when.

It is only right to point out that Cancer Research UK describes the evidence linking pesticide use to cancer as “inconclusive”. Moreover the amounts of pesticides found on fruits and vegetables are “tiny”. A spokeswoman said: “There is no evidence that they can damage health.”

That may well be the case but none of us goes through life being exposed to one chemical at a time. We are daily exposed to a cocktail of chemicals and there is little research on the effects that this ever-changing mixture might have.

Exposure to hormone-disrupting and potentially carcinogenic chemicals comes from all sorts of sources: plastic bottles, make-up and even our furniture.

We would find it hard to live without many of them and paradoxically some, such as brominated flame retardants, save lives. Similarly we rely on those villainous pesticides for cheap food. But something is going on in our wider environment.

In Europe male fish exposed to sewage treatment have become gender-benders with eggs in their testes. The widespread use of the now banned insecticide DDT in the Fifties caused birds of prey numbers to crash as the poison worked its way up the food chain. If these chemicals can cause such damage to wildlife why be surprised should their tentacles reach man?

If this hidden exposure is a problem there is not a lot you can do. The price of so many organic foods, for instance, means that shunning pesticides completely is an option open to few.

The glimmer of hope is that the treatment of cancer is improving every year. In the Seventies five out of 10 women with breast cancer survived beyond five years. Now the figure is more than eight out of 10. For prostate cancer the survival rate has risen in the same period from 30 per cent to 75 per cent.

Anyone who develops cancer, therefore, can look forward with some confidence to beating this nasty, insidious disease. And in the meantime there’s only one thing to do: enjoy yourself while you can.
“Do not underestimate chemicals”

Phil Dolling, TÜV SÜD REACh consultant commented “The Registration, Authorisation, Evaluation and Restriction of Chemicals legislation (REACh) is an extremely important piece of European Law and compliance with it is paramount in ensuring that potentially dangerous chemicals do not find their way into everyday consumer items.  We must never take for granted the importance of human health and protection of our environment.   We continually help our clients demonstrate compliance with REACh but even then the rapid alert system for non food products (RAPEX) lists non-conforming items every week as a result of market surveillance actions conducted throughout Europe.  Chemicals are found everywhere in common items such as cosmetics, paint and plastics.  Letting potentially hazardous chemicals slip into the supply chain is very dangerous, it just isn’t worth the gamble”.

Confused About EMC Testing?

What is EMC?
Electromagnetic Compatibility (EMC) is defined by the International Electrotechnical Commission (IEC) as:

The ability of a device, equipment or system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances to anything in that environment.

There are therefore two aspects to EMC; firstly controlling the electromagnetic 'noise' produced, also known as electromagnetic interference (EMI) or emissions; and secondly designing equipment to be sufficiently immune to intentional and unintentional electromagnetic sources in the environment so that it continues to operate correctly and does not become 'susceptible' to interference.

The problems of interference range from nuisance (e.g. poor quality TV/Radio reception) to unreliability (e.g. computer crashing) to safety (e.g. railway signalling failure).

Within Europe, electrical equipment with CE Marking meets the EU Electromagnetic Compatibility (EMC) Directive. The Directive has essential protection requirements for emissions and immunity to ensure that, for example; broadcast radio and television reception is unaffected by interference and that equipment will continue to operate adequately in the vicinity of radio transmitters such as mobile phones.

For manufacturers and suppliers in Europe, as well as EMC testing equipment under the EMC Directive, it is necessary to compile Technical Documentation, make a Declaration of Conformity and apply CE Marking. An option is to use an EMC Notified Body to provide an assessment.

What are EMC Emissions?

Emissions are described as the unwanted generation of electromagnetic energy.  Under the EMC Directive, the permitted levels of emissions are specified in Harmonised Standards for products, product families or generic environments. Usually it is necessary to perform EMC emission testing to demonstrate that the limits are met or if they are not met, to identify where design changes are required.

How can you prevent unwanted EMC Emissions?

The emissions can either be 'radiated' via electromagnetic fields that couple to other equipment or 'conducted' through wired connections such as the power cable. To prevent emissions it is possible to add filters and suppressors to cable interfaces, add cable or equipment shielding and grounding or change the circuit and PCB design.

What is EMC Immunity?

EMC Immunity (often called susceptibility) refers to the correct operation of electrical equipment in the presence of electromagnetic disturbances.  Under the EMC Directive, the minimum levels of immunity are specified in Harmonised Standards. Usually it is necessary to perform EMC immunity testing to demonstrate that the limits are met or if they are not met, to identify where design changes are required.

What can be done to increase immunity?

Interference can couple into equipment by the same routes as emissions, i.e. 'radiated' or 'conducted' coupling and similar measures can be applied such as to add filters and suppressors to cable interfaces, add cable or equipment shielding and grounding or change the circuit and PCB design.

TÜV SÜD establishes global structures for battery testing

TÜV SÜD is massively expanding its testing and certification activities for batteries of electrically powered vehicles. As announced at its press conference at eCarTec today, Tuesday 19 October, TÜV SÜD and its partner Lion Smart are investing several million euros in the construction of a new battery laboratory in Garching near Munich. The existing testing laboratories in Auburn Hills/USA and Singapore will be simultaneously expanded to the same standard as the laboratory designed for Munich. Under the roof of the recently established TÜV SÜD Battery Testing GmbH, the experts will then offer battery testing based on global safety standards.

"The new construction of the laboratory in Munich and the facilities in Auburn Hills and Singapore make TÜV SÜD the first provider of third-party testing services to operate an international network of testing laboratories for the batteries of electric vehicles", underlined Horst Schneider, TÜV SÜD AG Member of the Board responsible for MOBILITY. As Schneider emphasized, a priority for TÜV SÜD is to equip the testing laboratories and design the testing procedures in such a way that testing and certification can be performed to uniform standards and results are reproducible throughout the world: "We are thus responding to demands by industry, and can also play a critical role in ensuring high global standards in battery safety."

TÜV SÜD is investing several million euros in constructing the new laboratory on the premises of TÜV SÜD Automotive in Garching and in extending testing facilities in Auburn Hills and Singapore. Full operation of the Garching–based laboratory is scheduled for as early as mid-2011. The laboratory will test the chemical and electrical safety of new batteries for electrically powered vehicles and subject the high-voltage units to crash tests and 'abuse tests', i.e. tests which examine the risks faced when the batteries are operated or used incorrectly.

To implement its international campaign, TÜV SÜD and its partner Lion Smart GmbH have established TÜV SÜD Battery Testing GmbH to bundle their global battery testing activities. Lion Smart GmbH, based in Frieding and Herrsching, has been established in battery testing for years and is excellently integrated in both industry and science networks.

The Board of Management of TÜV SÜD Battery Testing GmbH comprises Daniel Quinger, now member of management at Lion Smart, and Stefan Rentsch, previously head of TÜV SÜD's "e-mobility innovation project". The company aims to establish a close partnership with TU München (technical university of Munich) and the Fraunhofer Institut in the field of battery design and development. "For TÜV SÜD, the present investment marks an important step towards establishing ourselves as the number one service provider in all safety issues of electromobility", explains Horst Schneider.

Electromobility is one of TÜV SÜD's core themes. The Munich-based provider of testing and certification services already covers the entire range of safety issues related to electric cars. At eCarTec, which continues until 21 October, TÜV SÜD can be found in Hall B5, Stand 330, where its experts provide information about a variety of themes including a new battery safety certificate for pedelecs, the development of roadworthiness testing for electric vehicles and charging systems, homologation and type approval of electric vehicles, and the training of staff in high-voltage technology and safe handling of the vehicles. The TÜV SÜD experts are also presenting a new standard for determining the range of electric vehicles.

The Halloween mask that’s not so “Great for parties”...

One of the latest products to be stopped from reaching our shelves is a Halloween mask for children.  The EU Toys Directive sets out the standards which all toys must meet as a minimum safety requirement. 
The mask, which was picked up by the Romanian Authorities, fails to meet the Directive as it has a lack of ventilation causing a risk of suffocation. 
The product packaging says “Great for parties”...we are not convinced!
Trick or Treat!
Retailers and consumers must be aware that unsafe products still find their way into our homes, however the majority of products are safe and do comply with safety standards. RAPEX, the EU rapid alert system for dangerous products issues a weekly report highlighting unsafe products picked up by market surveillance authorities such as Trading Standards, see http://ec.europa.eu/consumers/dyna/rapex/rapex_archives_en.cfm. 
To help combat these unsafe products TÜV SÜD works closely with manufacturers, importers, retailers and the market surveillance authorities.
“Not only do our safety compliance experts ensure that products meet international requirements, we routinely conduct product assessments and factory inspections to ensure ongoing safety and quality.”  Richard Poate, Compliance Services Manager, TÜV SÜD.
Our CE marking facility near Stratford conducts risk assessments for due diligence; product testing; compilation and checking of technical documentation and advises steps to be taken to ensure toys are reliably manufactured to the designed to 'safe specifications'.  “These services provide manufacturers with the tools and support necessary to be able for them to sell safe toys; it is vital to ensure that all due diligence is taken, especially where child safety is involved” Alastair McLaughlin, Toy Safety Specialist, TÜV SÜD.
The product is listed on the RAPEX report as item 19, Week 41, 2010.  Find the link here:

FAA issues safety alert on lithium batteries after UPS crash

The US FAA has issued a safety alert recommending that airlines adopt new procedures to reduce the risk of onboard fire posed by lithium batteries.

Airlines should ask customers to identify bulk shipments on airway bills and store such items in Class C cargo compartments, the FAA says. The agency also asks airlines to re-examine their own practices for transporting lithium batteries, as well as pay "special attention" to existing regulations.

The recommendations apply only to lithium batteries transported as cargo. Passengers and crewmembers can continue to use the power source without notifying the airline.

The safety alert was issued as the agency considers issuing a final rule with new proposals to reduce the risks of transporting such batteries. The proposed ruling is now under review by the Office of Management and Budget, which the administrative arm of the White House.

Non-peer-reviewed results of a study by the FAA Tech Centre show that lithium batteries can enter a condition called thermal runaway and reach temperatures over 593ºC (1,100ºF).

The safety alert comes one month after UPS flight 006, a Boeing 747-400, crashed in Dubai.
"Investigation of the crash is still underway, and the cause of the crash has not been determined," the FAA says. "We are aware, however, that the plane's cargo did include large quantities of lithium batteries and believe it prudent to advise operators of that fact."
Lithium-ion batteries deserve respect!
Richard Poate, Battery Certification Manager at TÜV Product Service, commented “lithium-ion batteries are found in more and more applications and whilst this chemistry provides great advantages in terms of performance we must never forget that this chemistry is quite volatile and must be treated with respect.  A key element of battery safety requires environmental and electrical testing to check their compliance during transportation.  Here at TÜV we routinely conduct such tests including altitude simulation, shock, vibration, short circuit and over-charge.  This recent incident just goes to reinforce the importance of battery testing in ensuring everyone’s safety.”
TÜV Product Service is accredited by UKAS to perform lithium-ion battery testing in accordance to UN Manual of Tests 38.3 Regulation.  This regulation is part of a wider set of regulations set out to ensure safety of goods during transit across air, sea and land. 
The environmental testing facilities at the purpose built testing laboratory in Fareham, Hampshire, covers an area of 1200m² and has a unique combination of test facilities.
It is also important that batteries are tested and that packaging handlers are trained to identify lithium-ion batteries from information provided and packaging markings and use approved methods for safe handling.

How do Military standards and testing differ to Commercial EMC test standards?

Both civil and military EMC standards are designed around the same principal, to prove that the equipment under test is fit for purpose and to operate in its intended environment.

However, military environment tend to be more hostile and therefore military EMC test levels are usually more severe. For example, the civil radiated immunity requirement for equipment intended for use in an industrial environment is a field strength of 10 V/m where as for military testing this can be 200 V/m and higher.

The driving force behind Commercial Test Standards and testing is EU legislation. A piece of commercial equipment will be tested to the correct product specific, product family or generic harmonised EU test standards. To ensure that a test in the UK to BS EN55011 will be just as relevant and acceptable as a test in Germany to DIN EN 55011 and in some cases to outside of the EU so that it’s also as relevant and acceptable as a test in Australia to AS/NZS CISPR 11.

The driving force behind Military testing are usually contractual requirements. A piece of military equipment will be tested to either the relevant countries own Military Test Standards (Def Stan for the UK, Mil Std for the US) or to the military standard that the country has chosen to adopt. In addition to this military equipment may then be subject to additional testing from product specific specifications.  For example, military aircraft may be subject to tests from the RTCA airborne test specifications as well as Def Stan or Mil Std. For larger military projects, specific product EMC Test Standards may be developed and written to cover that product only, an example of this is the EFA specs for the Euro-fighter project.

If we have a multi role piece of military hardware that is airborne, ship borne and also fitted to land vehicles then a complete set of Def Stan testing would be the very minimum required. If this product is also being marketed to the US, then a gap analysis of Def Stan to Mil Std specifications may be required to identify areas that Mil Std differs from Def Stan. On top of this, tests from the RTCA specifications will be relevant for the airborne version and Commercial Maritime test standards may be relevant for the ship borne version.

Fisher-Price recalls highchairs and toys

Thousands of high chairs and toys sold in the UK have been recalled by Fisher-Price over safety concerns. It is part of a wider US-led recall of more than 10 million products following reports of injuries. The UK recall of 72,763 high chairs follows 14 reports of problems in the US, including seven children who needed stitches.

Products with inflatable balls have also been recalled following 50 reports of valves coming off. The list of UK products which have been recalled has been issued by parent company Mattel.
The UK highchairs affected are the Basic Healthy Care Cow over the Moon, Flutterby Dream, Aquarium Healthy Care, 3-in-1 High Chair to Booster and Link Deluxe Healthy Care. About 72,763 of the chairs were sold in the UK between September 2001 and August 2010.
'Overwhelmingly safe'
Children could fall on pegs on the back of the high chairs, designed to store the tray, resulting in cuts and other injuries, the US Consumer Product Safety Commission (CPSC) said.
Some 165,090 products with inflatable balls have also been recalled in the UK after the CPSC said the valve of the ball could pose a choking hazard. The products include the Baby Playzone Crawl and Cruise Playground, Baby Playzone Crawl and Slide Arcade, Baby Gymtastics Play Wall, Ocean Wonders Kick and Crawl Aquarium, 1-2-3 Tetherball and the Bat and Score Goal. All the items were sold between July 2001 and July 2008.
A further 6,107 Little People Wheelies Stand 'n' Play Rampway toys sold between April and September 2010 have also been recalled after reports that the wheels on the cars could come off, posing a choking hazard.
A UK spokeswoman for Fisher-Price said:
“We want to reassure parents that our products are overwhelmingly safe. We operate in a highly regulated industry and we test our products at many stages during development and production. Our product engineers have many years of experience in designing safe toys.
"In addition, we monitor parents' safety-related reports over time. If we see an issue with a product at any point, even after many have been sold and used safely, we take appropriate action.
"Our actions reflect our continuing commitment to the safety of our products. Hundreds of millions of our products are used safely every day and we believe these simple fixes will continue that excellent record."

‘Panic or don’t panic?’
Although retailers and consumers must be aware that unsafe products still find their way into our homes, the majority of products are safe and do comply with safety standards.  RAPEX, the EU rapid alert system for dangerous products issues a weekly report highlighting unsafe products picked up by market surveillance authorities such as Trading Standards, see http://ec.europa.eu/consumers/dyna/rapex/rapex_archives_en.cfm.
