Take a look around your home.

0:00:040:00:06

Can you be sure every appliance is safe?

0:00:060:00:11

Is everything a company tells you about a product true?

0:00:110:00:16

And are you getting the best value for your money?

0:00:180:00:20

With the help of the country's top experts

0:00:200:00:23

we're going to see what it takes

0:00:230:00:25

to test the household products we use every day.

0:00:250:00:29

We'll discover how they're pushed to their limits.

0:00:320:00:35

We'll put the makers' claims on trial.

0:00:350:00:40

And show you how to make your money go further.

0:00:400:00:45

You'll find these products in any ordinary house.

0:00:450:00:48

But this is no ordinary house.

0:00:480:00:50

And no ordinary street.

0:00:500:00:53

This is the Watchdog Test House.

0:00:530:00:55

Hello, we're deep inside one of Britain's leading science centres.

0:01:010:01:05

Here at the Building Research Establishment

0:01:050:01:07

some of the products and materials that we use every day are put to the test.

0:01:070:01:13

To make sure that they are safe, environmentally friendly,

0:01:130:01:17

and that they don't fall apart.

0:01:170:01:19

Coming up on today's programme'

0:01:190:01:21

Thinking of leaving your appliances on overnight?

0:01:210:01:24

Be aware.

0:01:240:01:26

I do believe that we could have easily been killed that night.

0:01:260:01:29

The experts working behind the scenes to investigate the causes

0:01:290:01:32

of domestic fires AND ways to prevent them.

0:01:320:01:35

This is when the room starts to develop to flashover, when a fire in a room becomes a room on fire.

0:01:350:01:43

See-through packaging and elaborate names - just a few of the tricks

0:01:430:01:47

supermarkets use to encourage you to buy their products.

0:01:470:01:51

But do they really work?

0:01:510:01:52

I'm a big fan of actually being able to see what I'm actually going to buy, and these look nice.

0:01:520:01:57

And the hidden chemicals that caused allergic reactions.

0:01:570:02:01

It felt like 50% of my body was burnt.

0:02:010:02:06

Thousands of fires were caused last year by faulty household appliances

0:02:100:02:14

like dishwashers and washing machines.

0:02:140:02:16

The advice? Don't turn them on before you go to bed

0:02:160:02:19

or when you leave the house. It may sound extreme.

0:02:190:02:22

Until you find out just how hazardous they CAN be.

0:02:220:02:26

On 6th July, 2012, Martin Squires was at home with his wife and three children.

0:02:260:02:32

I'd just been to check on my five-year-old son

0:02:320:02:36

and, on returning back to the room,

0:02:360:02:38

I thought I'd just pop into the kitchen for a glass of water.

0:02:380:02:41

Now, I'm glad I did at that point, because the dishwasher was

0:02:410:02:45

making a strange noise and I looked round and saw a slight bit of smoke

0:02:450:02:49

coming out from the control panel followed by a burst of flames.

0:02:490:02:53

His dishwasher was on fire.

0:02:530:02:56

Luckily, Martin got to the plug in time and managed to switch it off.

0:02:560:03:00

I grabbed hold of the door and wafted it, to extinguish the flames.

0:03:000:03:04

The room was just filled with a black, acrid smoke which affected

0:03:040:03:08

all of us in the house, we were coughing, we had to open all the windows.

0:03:080:03:12

If it hadn't been for Martin's quick actions, the consequences could have been much more serious.

0:03:120:03:17

Sometimes we would put the dishwasher on just before going to bed.

0:03:170:03:23

If that had been the case, I do believe that we could have easily

0:03:230:03:26

been killed that night.

0:03:260:03:28

So what was it that went so horribly wrong?

0:03:280:03:31

Well, as a qualified electrician, Martin was able to investigate the source of the fire himself.

0:03:310:03:36

I realised it was an internal component on a PCB.

0:03:360:03:41

Basically, on the dishwasher, this controls all the programmes - that was over heating and

0:03:410:03:48

catching fire. Now, that shouldn't be happening.

0:03:480:03:51

No, it shouldn't. The company agreed and recalled the appliance. But it took them nine months.

0:03:510:03:57

Although Martin had identified the fault with his dishwasher,

0:04:000:04:04

the company needed to look into whether this was a one-off fault,

0:04:040:04:07

or actually a design fault.

0:04:070:04:09

So what happens when a faulty kitchen appliance causes a fire that destroys a whole kitchen?

0:04:090:04:15

How does a manufacturer begin to investigate that?

0:04:150:04:18

Well, they may turn to this man, Peter Mansi, of Fire Investigations UK,

0:04:180:04:22

an independent company specialising in investigating the causes of fire.

0:04:220:04:27

Our remit is to identify the true causes of fires.

0:04:270:04:30

Until we know that, we can't put prevention methods in place

0:04:300:04:35

to stop them happening again.

0:04:350:04:37

Whether it's to work with the manufacturer,

0:04:370:04:41

to perhaps promote a recall notice,

0:04:410:04:44

or even a redesign of an appliance

0:04:440:04:46

and to share that with the public at large

0:04:460:04:49

to make it a safer environment for everybody.

0:04:490:04:51

Later, we'll be finding out just how they do this

0:04:510:04:54

here at the Building Research Establishment.

0:04:540:04:57

And if you're not yet convinced of the risks of leaving your dishwasher unattended,

0:04:570:05:01

you'd better keep watching.

0:05:010:05:03

We spend an impressive £1,500,000 on our food shopping every week.

0:05:110:05:15

It's big business, which is why our every move between the aisles

0:05:150:05:19

has been carefully studied, to try and discover the secrets of what we buy, and why.

0:05:190:05:25

And companies certainly put what they learn to good use, turning it into marketing tricks and techniques

0:05:250:05:31

that influence how we shop, without us ever realising.

0:05:310:05:35

Ah. Yes, Sophie, the weekly shop.

0:05:350:05:39

Whether it's a quick dash in for the essentials or a big trip to

0:05:390:05:42

buy the family groceries, you might think that what we choose to put into our baskets

0:05:420:05:46

is entirely up to us.

0:05:460:05:48

But you'd be wrong.

0:05:480:05:50

So when consumers are out shopping, they use lots of intuition,

0:05:500:05:54

lots of emotions,

0:05:540:05:55

and retailers are really trying to tap into those

0:05:550:05:59

mental short cuts that people have, that consumers have,

0:05:590:06:02

and really what they're trying to do is increase perceptions of quality

0:06:020:06:06

or perceptions of taste of products by tapping in to those mental short cuts.

0:06:060:06:11

So, we're going to reveal how they do it, why they do it and whether we REALLY fall for it.

0:06:110:06:19

Taking price out of the equation, the key battle ground for quality

0:06:190:06:22

and trust is not necessarily what's in the product, but what's on

0:06:220:06:25

the outside - the packaging.

0:06:250:06:27

So, for our test, we're going to be designing our own.

0:06:270:06:30

One of the recent trends in packaging is transparent packaging,

0:06:300:06:34

the ability for consumers to actually see the product.

0:06:340:06:38

This is a really effective way of influencing consumers simply because

0:06:380:06:42

when they're able to see the product they're able to actually imagine

0:06:420:06:46

either tasting or using that product.

0:06:460:06:49

So that's exactly what we're going to do with our first product.

0:06:490:06:55

Although these two packets of biscuits look very similar,

0:06:550:06:58

we're giving one of them a window, so shoppers can see the biscuits on the inside.

0:06:580:07:02

Now, what happens when people pass these sorts of packaging

0:07:020:07:06

is that they barely noticing the non see-through one, but they are much

0:07:060:07:09

more likely to stop on the see-through packaging.

0:07:090:07:13

Next, how the product is described - cue our version of a convenience lasagne.

0:07:130:07:19

More and more, retailers will use very specific language to describe products.

0:07:190:07:24

This could be things like "home-made", like "premium", or "luxury".

0:07:240:07:29

These sorts of words trigger positive memories,

0:07:290:07:32

positive associations, which again are related to quality.

0:07:320:07:36

So this simple beef lasagne becomes

0:07:360:07:38

"Luxury Select Beef Lasagne,

0:07:380:07:41

"with a rich tomato ragu and a creamy bechamel sauce."

0:07:410:07:45

Delicious.

0:07:450:07:47

But why stop there?

0:07:470:07:50

Another interesting element that retailers use on packaging is sense of place,

0:07:500:07:54

the origins of the product. It could be things like

0:07:540:07:57

Italian home-made or authentic Indian or from a Scottish farm, for instance,

0:07:570:08:02

so that particular sense of place gives an authenticity to the product

0:08:040:08:08

and perceptions of quality of that product and therefore consumers are more likely to choose it, as well.

0:08:080:08:14

So, for our final product, we're transforming a simple pork sausage

0:08:140:08:20

into one from a rural idyll of Cottage Lane Farm.

0:08:200:08:24

And where is that, you might ask?

0:08:240:08:25

Well, it doesn't exist. We've made it up.

0:08:250:08:28

Just like Marks and Spencer's did with their Lochmuir Salmon.

0:08:280:08:32

It may hint at a classic Scottish lake, but there's no such place

0:08:320:08:36

as Lochmuir.

0:08:360:08:38

And although Oakham, Marks and Spencer's chicken brand, is a real place,

0:08:380:08:42

not all the chicken packaged as such comes from there.

0:08:420:08:46

The same is true of Willow Farm, from Tesco.

0:08:460:08:49

Even though it's not real, consumers are unaware of this

0:08:490:08:53

and they will still associate the same type of quality and the same type

0:08:530:08:57

of trustworthiness as the real places.

0:08:570:09:00

And it's perfectly legal. Supermarkets CAN invent a place like this for marketing purposes.

0:09:000:09:06

Tesco says they use British chickens from a number of different farms, one of which is called Willow Farm.

0:09:060:09:13

Marks and Spencer's told us that Oakham chickens come from UK farms

0:09:130:09:17

with both the name of the farmer and the county where the bird has been

0:09:170:09:21

reared listed on the pack.

0:09:210:09:22

They add that all Lochmuir fish sold is Scottish and on most products

0:09:220:09:27

they also list the name of the loch where it is sourced.

0:09:270:09:30

I would be very surprised that Lochmuir's not a real place, what have they put it on there for?

0:09:300:09:34

If the chicken is not from Oakham, why do you use this name?

0:09:340:09:39

So, we've now seen some of the techniques we're exposed to every time we go shopping.

0:09:390:09:45

What we really want to know is how effective they are.

0:09:450:09:48

So we're going to put our specially designed products through their

0:09:480:09:52

paces with a group of volunteer shoppers - will the psychology work

0:09:520:09:55

on them? Find out later.

0:09:550:09:58

Now, chemicals are all around us. And it's a difficult area to control and regulate.

0:10:020:10:07

From cosmetics to sofas, it seems you never quite know where the next allergic reaction could come from.

0:10:070:10:14

At least, that's what we've discovered on Watchdog. Here's Lynn Faulds Wood.

0:10:140:10:18

'Welcome to Watchdog. In tonight's programme, all these people have written to us.'

0:10:210:10:27

'With the new Lemon Fresh Fairy, you've got all the sense of Fairy, all the scent of lemon.'

0:10:270:10:33

Fairy liquid - over the years the ads told us it was mild and green.

0:10:330:10:39

But as Watchdog discovered in 1996,

0:10:390:10:43

the later, lemon versions could cause severe allergic reactions.

0:10:430:10:48

It's like a burning feeling, at times. When I put my hand

0:10:480:10:51

in cold water, it cools it down, but when I put my hand in hot water,

0:10:510:10:54

it really burns again.

0:10:540:10:57

Lemon Fairy had an acidity about it which was great for dishes,

0:10:570:11:01

but according to some viewers, it could be painful for hands.

0:11:010:11:06

After that first report, Watchdog heard from many more of you.

0:11:060:11:12

In fact, over 200 people got in touch about old and new versions of Lemon Fairy.

0:11:120:11:19

After Watchdog took sufferers to try to meet him,

0:11:190:11:21

the dermatologist advising Fairy's parent company, Procter and Gamble,

0:11:210:11:26

finally admitted that hundreds more could be affected.

0:11:260:11:30

I would reckon about 6% of our population are sensitive

0:11:300:11:35

to the kind of damage that fat extraction by a detergent can do to their skin.

0:11:350:11:43

The tests we have done seem to show that it is less damaging to hands than other people's products.

0:11:430:11:51

As a result of Watchdog's campaign, Fairy and other manufacturers put

0:11:510:11:56

warning labels for people with sensitive skin on the back of their products.

0:11:560:12:00

Fairy say their formula has been scientifically proven to be safe,

0:12:000:12:05

so no change was made to the formulation, although over time,

0:12:050:12:08

improvements have been made.

0:12:080:12:11

But nine years later, Watchdog was encountering worse problems with hair dyes.

0:12:110:12:16

The pictures you've sent us are not a pretty sight.

0:12:160:12:20

This is Keely Not, before she dyed her hair.

0:12:200:12:24

This is the horror picture afterwards.

0:12:240:12:28

This is Lara Danson before dying her hair.

0:12:280:12:30

Here's what happened.

0:12:320:12:34

They were all reacting to a chemical called PPD.

0:12:340:12:38

PD is a toxic chemical found in black rubber, photocopy ink and petrol.

0:12:380:12:45

It's also found in most modern hair dyes,

0:12:450:12:48

at the hairdressers and in home kits.

0:12:480:12:51

Yes, a toxic chemical that companies weren't making a big effort to warn people about.

0:12:510:12:57

Following Watchdog's reports, manufacturers did agree to put bigger warnings on packs.

0:12:570:13:03

But why do these problems keep happening?

0:13:030:13:07

The prime culprits are the preservatives,

0:13:070:13:12

the fragrance chemicals and the hair dyes.

0:13:120:13:16

All powerful chemicals, that for some products, manufacturers say they can't do without.

0:13:160:13:22

The trick is to keep exposure to problematic substances as low as

0:13:220:13:26

possible, so that they are effective

0:13:260:13:31

in whatever role they have,

0:13:310:13:33

but, at the same time, minimising the risk to the consumer.

0:13:330:13:39

But there are some chemicals that cause reactions that CAN be removed.

0:13:410:13:45

And it would take Watchdog to make that happen, too.

0:13:450:13:49

In 2013, over 150 viewers contacted Watchdog

0:13:490:13:54

to complain about reactions they'd suffered after using Piz Buin.

0:13:540:13:58

Sophie Holmes used the cream for the first time on her face while skiing.

0:13:580:14:03

It got worse and worse and started to swell on my face and neck.

0:14:030:14:08

So I went straight to A&E in London.

0:14:080:14:11

They prescribed me with steroids, to reduce the swelling, because there

0:14:110:14:16

was a worry it was restricting my airways and could become fatal.

0:14:160:14:21

She was allergic to a chemical known as Methylisothiazolinone, otherwise known as MI.

0:14:210:14:27

It turned out dermatologists were seeing far more people

0:14:270:14:31

with allergies to MI than would ordinarily be acceptable.

0:14:310:14:35

Allergy to it is now at epidemic proportions in the United Kingdom,

0:14:370:14:40

such that, at the present time, about 10% of patients

0:14:400:14:43

we investigate are now allergic to Methylisothiazolinone.

0:14:430:14:48

After Watchdog investigated, the owners of Piz Buin, Johnson and Johnson, announced MI would be

0:14:480:14:54

removed from the formula.

0:14:540:14:56

Other brands followed suit.

0:14:560:14:59

Now, you might be careful about what you put on your skin,

0:14:590:15:03

especially after seeing stories like that,

0:15:030:15:05

yet one of our more shocking cases of chemicals causing reactions

0:15:050:15:10

came from a completely-unexpected source.

0:15:100:15:13

In 2008, the programme investigated complaints about sofas

0:15:160:15:21

giving people severe rashes.

0:15:210:15:23

The sofas were bought at three high street stores,

0:15:230:15:26

but made by a Chinese company.

0:15:260:15:28

I came out in an awful, awful rash, with huge blisters,

0:15:300:15:36

and it was very painful and sore.

0:15:360:15:39

It felt like... 50% of my body was burnt.

0:15:390:15:44

Tracey was in and out of hospital for six months,

0:15:440:15:48

going through surgical biopsies, morphine and low-level chemotherapy.

0:15:480:15:54

When she got home, she'd just collapse on the sofa,

0:15:540:15:57

exhausted by the pain.

0:15:570:15:58

Tracey finally worked out she was actually reacting

0:15:580:16:03

to something in her sofa.

0:16:030:16:05

Her problem cleared up when she got rid of it.

0:16:050:16:08

As Watchdog revealed, the cause was a small sachet of fungicide,

0:16:080:16:13

put in to protect the fabric.

0:16:130:16:15

It should never have been in the sofa in the first place.

0:16:150:16:18

This might amaze you... There are currently controls

0:16:200:16:24

on some 30,000 ingredients and even more that are banned.

0:16:240:16:28

So whether it's in sofas or sun creams, we may not know

0:16:280:16:32

where the next potentially-harmful chemical will appear.

0:16:320:16:35

What we do know is, thanks to the regulators,

0:16:350:16:38

the products we use today are much safer.

0:16:380:16:42

Now, kettles - you can spend as little as £5 or as much as £195.

0:16:460:16:52

They all boil hot water, so why IS there such a price range?

0:16:520:16:56

Is it all in the look

0:16:560:16:57

or do some justify a higher price tag for performance?

0:16:570:17:02

Well, a man who has tested all kinds of kettles on the market

0:17:020:17:05

is Richard Headland, from Which?

0:17:050:17:07

Now, nice cup of tea here, made with a £5 kettle.

0:17:070:17:10

If we'd spent £195 on our kettle, would it have made much difference?

0:17:100:17:15

Chances are, Sophie,

0:17:150:17:16

it wouldn't have made much difference to the end result.

0:17:160:17:20

We've still got a cup of tea, but what you may want to consider is how

0:17:200:17:24

quickly your kettle is going to boil. The slowest kettles in our test

0:17:240:17:28

take around two minutes slower to boil a litre of water

0:17:280:17:31

than the fastest ones. So, a big difference.

0:17:310:17:33

There's also a big difference in noise.

0:17:330:17:35

That's a big bug-bear people have.

0:17:350:17:38

If you spend more money on your kettle, will that mean

0:17:380:17:41

-your kettle will last longer?

-Not necessarily.

0:17:410:17:43

You find some cheaper brands that last for ages.

0:17:430:17:47

You find some expensive brands that don't last so long.

0:17:470:17:49

Ultimately, a kettle is going to give up on you at some point -

0:17:490:17:52

the element's going to fail.

0:17:520:17:54

I wouldn't spend more if you're looking for durability.

0:17:540:17:57

If you want to save money on energy bills,

0:17:570:17:59

you should think about how much you are filling your kettle,

0:17:590:18:02

-because it does make a difference?

-That's probably the thing

0:18:020:18:04

that will make the biggest difference to your energy bills.

0:18:040:18:06

So, if you are boiling, say, a litre of water, which is about

0:18:060:18:09

enough for four cups of tea, doing that five times a day,

0:18:090:18:12

over a year, that's going to cost you more than £31.

0:18:120:18:15

If you were just boiling enough for one cup of tea,

0:18:150:18:18

that would cost you around £10 over the year, so quite a big difference.

0:18:180:18:21

One thing to remember is, very often,

0:18:210:18:24

you're paying a higher price simply for the look -

0:18:240:18:26

-for the style, for the elegance, perhaps?

-Absolutely.

0:18:260:18:29

There's no reason why you can't spend £10 or less

0:18:290:18:32

for an own-brand kettle. Indeed, in our tests,

0:18:320:18:36

there are loads of best buys for, sort of, £20 upwards,

0:18:360:18:39

-so well worth considering.

-Richard, thank you.

0:18:390:18:42

Earlier, we saw some of the methods manufacturers use

0:18:460:18:50

to try to influence what we buy.

0:18:500:18:52

So we've designed our own packaging and set up our own supermarket,

0:18:520:18:56

to see if those marketing tricks really work.

0:18:560:18:59

Now, all we need are some customers.

0:18:590:19:02

Yes, Sophie, and here they are -

0:19:040:19:06

eight randomly-selected supermarket shoppers -

0:19:060:19:09

to whom we've given a simple shopping list of items to buy.

0:19:090:19:12

Our shop is stocked up with two choices for each

0:19:120:19:15

of the shopping items on the list,

0:19:150:19:16

including the three products that have had our shopping psychology

0:19:160:19:20

treatment - the biscuits with the see-through versus closed packets,

0:19:200:19:23

our elaborately-described versus simple lasagne

0:19:230:19:27

and our standard versus Cottage Lane Farm sausages.

0:19:270:19:30

Will our volunteers be influenced by our sneaky packaging?

0:19:300:19:34

First up, our biscuits.

0:19:340:19:37

I'm a big fan of actually being able to see what I'm going to buy

0:19:370:19:40

and these, they look nice.

0:19:400:19:42

I like it when I see it, cos then I get what I expect.

0:19:420:19:44

I'm going to go for these ones. It's just like a try before you buy -

0:19:440:19:48

if you see it, you're more likely to buy it.

0:19:480:19:50

An impressive seven out of eight plumped for the product

0:19:500:19:53

that had the biscuits on display. So, no surprise there.

0:19:530:19:57

When our volunteers see these packages,

0:19:570:20:00

when they see the see-through packaging in particular,

0:20:000:20:02

they are likely to have a chemical reaction.

0:20:020:20:06

The chemical dopamine is likely to be released,

0:20:060:20:08

which kind of triggers this sort of reward and pleasure system,

0:20:080:20:12

which we will feel when we actually eat the product,

0:20:120:20:14

so they're simulating eating

0:20:140:20:16

when they're actually seeing that particular product.

0:20:160:20:19

What about our ready meal?

0:20:190:20:20

Which is the most likely to make the dining table?

0:20:200:20:23

Remember, one of these isn't just beef lasagne,

0:20:230:20:26

it's a luxury beef lasagne with a rich ragu and creamy bechamel sauce.

0:20:260:20:31

So, that sounds very, very good. It's luxury.

0:20:310:20:37

Mm.

0:20:370:20:38

OK, they look pretty similar but I do like the lingo on that.

0:20:380:20:42

This time, five out of eight went for our more descriptive version.

0:20:420:20:47

Now, I was, of course, expecting this to happen,

0:20:470:20:49

but it really never ceases to surprise me how small changes

0:20:490:20:53

to the packaging, such as words, can have such a big effect on consumers.

0:20:530:20:58

And finally, our mythical farm sausage also came out on top,

0:21:010:21:04

with six out of eight opting for the Cottage Lane version.

0:21:040:21:07

Cottage Lane, I will choose the Cottage Lane.

0:21:070:21:10

It's, basically, showing me where my product has been sourced from

0:21:100:21:14

and it's got a picture of the farm here.

0:21:140:21:17

The pigs are going there on the farm and not in a factory.

0:21:170:21:22

I'm assuming that if the pigs came from this lovely place

0:21:220:21:25

then they probably taste nice, too.

0:21:250:21:27

So it's clear, we're all open to the influence of the supermarket

0:21:290:21:32

tricks, whether we realise it or not. Even Gorkan, it seems.

0:21:320:21:37

What never really ceases to surprise me is the fact that

0:21:370:21:41

I know all this stuff and yet I'm still influenced by it.

0:21:410:21:44

'I simply cannot control it myself.'

0:21:440:21:47

It's very difficult to do anything about them.

0:21:470:21:50

Back now to dishwashers and earlier we heard how household

0:21:530:21:57

appliances were responsible for thousands of fires last year.

0:21:570:22:01

Well, here at the Building Research Establishment

0:22:010:22:03

teams of specialists are working hard to find out what causes

0:22:030:22:07

such fires and how to prevent them.

0:22:070:22:09

This is their fire testing facility, the largest of its kind in Europe.

0:22:100:22:16

They work alongside Fire Investigations UK to provide

0:22:160:22:19

vital information once a fire has happened.

0:22:190:22:22

It can be crucial evidence that can save lives.

0:22:220:22:25

Our remit is to identify the origin of the fire,

0:22:250:22:29

where a fire started and what caused the fire.

0:22:290:22:33

'When we do a full-scale reconstruction it's to replicate

0:22:330:22:36

'how that fire developed in the real circumstances'

0:22:360:22:39

and that's what we're going to try and show you here today.

0:22:390:22:42

They need to rig this dishwasher with a simple fault,

0:22:420:22:45

something that could occur on any machine.

0:22:450:22:47

'When appliances are moved around a lot,

0:22:480:22:51

'perhaps if they've moved from one property to another and

0:22:510:22:54

'they haven't been handled carefully, you could get a loose connection.'

0:22:540:22:58

If you don't have a tight connection on some of these high energy

0:22:580:23:02

electrical conductors, it will create resistance at that point

0:23:020:23:07

and it will start to glow, like a small electric heater.

0:23:070:23:11

'If there's plastic around it then it can ignite the plastic

0:23:110:23:15

'or any other combustible material.'

0:23:150:23:17

When they do catch fire then there's normally quite a serious consequence.

0:23:170:23:22

The kitchen is constructed ready for the fire

0:23:220:23:25

and Peter replicates the loose connection fault on our dishwasher.

0:23:250:23:29

Everything is set for the reconstruction.

0:23:290:23:32

Let the fire commence.

0:23:320:23:34

Five, four, three, two, one.

0:23:340:23:38

Ignition.

0:23:380:23:41

So here we're simulating a fault within the dishwasher,

0:23:410:23:44

for instance a bad connection, which would result in resistance heating.

0:23:440:23:49

The electrical connection heats up

0:23:490:23:51

and ignites the plastic within the appliance.

0:23:510:23:54

A pilot flame is created and the dishwasher is now on fire.

0:23:540:23:58

We're a minute in and there's enough smoke

0:23:580:24:00

to activate the smoke detector.

0:24:000:24:01

SMOKE DETECTOR BLEEPS

0:24:010:24:04

We can now see the fire has actually taken hold of the appliance

0:24:070:24:10

and it will start to spread to the timber cabinets next door to it.

0:24:100:24:15

As the fire develops, the plastic drips onto the floor.

0:24:180:24:22

If this were a real fire in a real kitchen the wooden or lino floor

0:24:220:24:27

would also go up in flames.

0:24:270:24:29

The flames are now starting to reach up into the smoke layer.

0:24:310:24:36

You can see the cabinets either side of the dishwasher are starting to

0:24:360:24:39

ignite and we're now getting a more rapidly developing fire.

0:24:390:24:44

In less than 25 minutes, the temperature on the ceiling

0:24:450:24:49

reaches 300C.

0:24:490:24:52

The burning cupboards and the worktop are adding fuel to the fire.

0:24:520:24:56

MUSIC

0:24:560:24:58

And this is when a room starts to develop to flashover,

0:25:040:25:07

when the fire in a room becomes a room on fire.

0:25:070:25:11

And everything in the room will ignite.

0:25:110:25:13

One minute later, almost everything in the room is on fire.

0:25:130:25:17

In a real house, with added furnishings, the fire would

0:25:170:25:20

reach this intensity even faster.

0:25:200:25:23

'And we can see flames developing along the ceiling

0:25:250:25:27

'and the radiated heat is quite intolerable.'

0:25:270:25:31

OK, thanks for your help.

0:25:340:25:36

OK.

0:25:360:25:37

The fire is extinguished before it becomes uncontrollable.

0:25:370:25:42

'So here we can see the aftermath of what is a relatively small

0:25:510:25:55

'and contained fire in a kitchen

0:25:550:25:57

'and we can see the devastation that this has caused, and the smoke

0:25:570:26:00

'damage would be 100% throughout the property by this stage.'

0:26:000:26:05

Fire reconstructions like this are key to understanding how

0:26:050:26:09

fires develop, but Fire Investigations UK also attend

0:26:090:26:13

the aftermath of real fires, to determine the cause and origin.

0:26:130:26:18

So a second fire investigator, John Galvin, is going to take

0:26:180:26:21

a look at our burnt-out kitchen, to show us just how it's done.

0:26:210:26:25

Now, in this particular room, we can see that the most damaged area

0:26:260:26:30

is the far side and we can see on that particular wall,

0:26:300:26:34

we have flame impingement and that is an indicator for us that that

0:26:340:26:38

area was severely affected by the fire whilst it was in progress.

0:26:380:26:42

John is particularly interested in the appliances on the left-hand

0:26:420:26:46

side of the kitchen.

0:26:460:26:47

'I can see from here, a kettle, a toaster

0:26:490:26:51

'and there appears to be some measuring scales at the end.'

0:26:510:26:54

Could they actually be part of the cause of this fire?

0:26:540:26:57

If this had been a real fire, every appliance in the room would be

0:26:570:27:01

examined to determine whether it had been switched on at the time.

0:27:010:27:05

If not, it would be eliminated as a potential cause,

0:27:050:27:08

but John has already found another clue.

0:27:080:27:11

The table has scorching on the side facing what

0:27:110:27:14

we believe to be the area of origin.

0:27:140:27:15

Additionally we have some shadowing on one of the chairs under the table,

0:27:150:27:19

-which shows an area protected by the table leg.

-Getting warmer, John.

0:27:190:27:25

So all the data we've gathered so far are pointing us

0:27:250:27:29

towards this appliance.

0:27:290:27:30

So, if I just pop the door open.

0:27:300:27:32

What I can see now is that the internal surfaces of this

0:27:350:27:39

particular appliance are very heavily coated with smoke deposits.

0:27:390:27:43

There's also none of the plastic internal components remaining,

0:27:430:27:47

so we can say that this particular appliance has suffered

0:27:470:27:50

greatly during this fire.

0:27:500:27:52

John quickly suspects that the dishwasher did start the fire.

0:27:530:27:57

Next, it would go to the lab, to confirm if he was right.

0:27:570:28:01

'Fire investigation gets to the bottom of why fires occur'

0:28:010:28:04

and by feeding that information back to the manufacturers we try

0:28:040:28:08

'and prevent such things happening again in the future.

0:28:080:28:12

'If things happen time and time again and we identify a pattern,'

0:28:120:28:15

we may be able to persuade the manufacturer to actually do

0:28:150:28:18

a recall or certainly alert members of the public to the

0:28:180:28:21

potential of a problem with a particular device.

0:28:210:28:25

0:28:320:28:35

That's all for today. Thanks for watching.
