Take a look around your home. | 0:00:04 | 0:00:06 | |
Can you be sure every appliance is safe? | 0:00:06 | 0:00:11 | |
Is everything a company tells you about a product true? | 0:00:11 | 0:00:16 | |
And are you getting the best value for your money? | 0:00:18 | 0:00:20 | |
With the help of the country's top experts | 0:00:20 | 0:00:23 | |
we're going to see what it takes | 0:00:23 | 0:00:25 | |
to test the household products we use every day. | 0:00:25 | 0:00:29 | |
We'll discover how they're pushed to their limits. | 0:00:32 | 0:00:35 | |
We'll put the makers' claims on trial. | 0:00:35 | 0:00:40 | |
And show you how to make your money go further. | 0:00:40 | 0:00:45 | |
You'll find these products in any ordinary house. | 0:00:45 | 0:00:48 | |
But this is no ordinary house. | 0:00:48 | 0:00:50 | |
And no ordinary street. | 0:00:50 | 0:00:53 | |
This is the Watchdog Test House. | 0:00:53 | 0:00:55 | |
Hello, we're deep inside one of Britain's leading science centres. | 0:01:01 | 0:01:05 | |
Here at the Building Research Establishment | 0:01:05 | 0:01:07 | |
some of the products and materials that we use every day are put to the test. | 0:01:07 | 0:01:13 | |
To make sure that they are safe, environmentally friendly, | 0:01:13 | 0:01:17 | |
and that they don't fall apart. | 0:01:17 | 0:01:19 | |
Coming up on today's programme' | 0:01:19 | 0:01:21 | |
Thinking of leaving your appliances on overnight? | 0:01:21 | 0:01:24 | |
Be aware. | 0:01:24 | 0:01:26 | |
I do believe that we could have easily been killed that night. | 0:01:26 | 0:01:29 | |
The experts working behind the scenes to investigate the causes | 0:01:29 | 0:01:32 | |
of domestic fires AND ways to prevent them. | 0:01:32 | 0:01:35 | |
This is when the room starts to develop to flashover, when a fire in a room becomes a room on fire. | 0:01:35 | 0:01:43 | |
See-through packaging and elaborate names - just a few of the tricks | 0:01:43 | 0:01:47 | |
supermarkets use to encourage you to buy their products. | 0:01:47 | 0:01:51 | |
But do they really work? | 0:01:51 | 0:01:52 | |
I'm a big fan of actually being able to see what I'm actually going to buy, and these look nice. | 0:01:52 | 0:01:57 | |
And the hidden chemicals that caused allergic reactions. | 0:01:57 | 0:02:01 | |
It felt like 50% of my body was burnt. | 0:02:01 | 0:02:06 | |
Thousands of fires were caused last year by faulty household appliances | 0:02:10 | 0:02:14 | |
like dishwashers and washing machines. | 0:02:14 | 0:02:16 | |
The advice? Don't turn them on before you go to bed | 0:02:16 | 0:02:19 | |
or when you leave the house. It may sound extreme. | 0:02:19 | 0:02:22 | |
Until you find out just how hazardous they CAN be. | 0:02:22 | 0:02:26 | |
On 6th July, 2012, Martin Squires was at home with his wife and three children. | 0:02:26 | 0:02:32 | |
I'd just been to check on my five-year-old son | 0:02:32 | 0:02:36 | |
and, on returning back to the room, | 0:02:36 | 0:02:38 | |
I thought I'd just pop into the kitchen for a glass of water. | 0:02:38 | 0:02:41 | |
Now, I'm glad I did at that point, because the dishwasher was | 0:02:41 | 0:02:45 | |
making a strange noise and I looked round and saw a slight bit of smoke | 0:02:45 | 0:02:49 | |
coming out from the control panel followed by a burst of flames. | 0:02:49 | 0:02:53 | |
His dishwasher was on fire. | 0:02:53 | 0:02:56 | |
Luckily, Martin got to the plug in time and managed to switch it off. | 0:02:56 | 0:03:00 | |
I grabbed hold of the door and wafted it, to extinguish the flames. | 0:03:00 | 0:03:04 | |
The room was just filled with a black, acrid smoke which affected | 0:03:04 | 0:03:08 | |
all of us in the house, we were coughing, we had to open all the windows. | 0:03:08 | 0:03:12 | |
If it hadn't been for Martin's quick actions, the consequences could have been much more serious. | 0:03:12 | 0:03:17 | |
Sometimes we would put the dishwasher on just before going to bed. | 0:03:17 | 0:03:23 | |
If that had been the case, I do believe that we could have easily | 0:03:23 | 0:03:26 | |
been killed that night. | 0:03:26 | 0:03:28 | |
So what was it that went so horribly wrong? | 0:03:28 | 0:03:31 | |
Well, as a qualified electrician, Martin was able to investigate the source of the fire himself. | 0:03:31 | 0:03:36 | |
I realised it was an internal component on a PCB. | 0:03:36 | 0:03:41 | |
Basically, on the dishwasher, this controls all the programmes - that was over heating and | 0:03:41 | 0:03:48 | |
catching fire. Now, that shouldn't be happening. | 0:03:48 | 0:03:51 | |
No, it shouldn't. The company agreed and recalled the appliance. But it took them nine months. | 0:03:51 | 0:03:57 | |
Although Martin had identified the fault with his dishwasher, | 0:04:00 | 0:04:04 | |
the company needed to look into whether this was a one-off fault, | 0:04:04 | 0:04:07 | |
or actually a design fault. | 0:04:07 | 0:04:09 | |
So what happens when a faulty kitchen appliance causes a fire that destroys a whole kitchen? | 0:04:09 | 0:04:15 | |
How does a manufacturer begin to investigate that? | 0:04:15 | 0:04:18 | |
Well, they may turn to this man, Peter Mansi, of Fire Investigations UK, | 0:04:18 | 0:04:22 | |
an independent company specialising in investigating the causes of fire. | 0:04:22 | 0:04:27 | |
Our remit is to identify the true causes of fires. | 0:04:27 | 0:04:30 | |
Until we know that, we can't put prevention methods in place | 0:04:30 | 0:04:35 | |
to stop them happening again. | 0:04:35 | 0:04:37 | |
Whether it's to work with the manufacturer, | 0:04:37 | 0:04:41 | |
to perhaps promote a recall notice, | 0:04:41 | 0:04:44 | |
or even a redesign of an appliance | 0:04:44 | 0:04:46 | |
and to share that with the public at large | 0:04:46 | 0:04:49 | |
to make it a safer environment for everybody. | 0:04:49 | 0:04:51 | |
Later, we'll be finding out just how they do this | 0:04:51 | 0:04:54 | |
here at the Building Research Establishment. | 0:04:54 | 0:04:57 | |
And if you're not yet convinced of the risks of leaving your dishwasher unattended, | 0:04:57 | 0:05:01 | |
you'd better keep watching. | 0:05:01 | 0:05:03 | |
We spend an impressive £1,500,000 on our food shopping every week. | 0:05:11 | 0:05:15 | |
It's big business, which is why our every move between the aisles | 0:05:15 | 0:05:19 | |
has been carefully studied, to try and discover the secrets of what we buy, and why. | 0:05:19 | 0:05:25 | |
And companies certainly put what they learn to good use, turning it into marketing tricks and techniques | 0:05:25 | 0:05:31 | |
that influence how we shop, without us ever realising. | 0:05:31 | 0:05:35 | |
Ah. Yes, Sophie, the weekly shop. | 0:05:35 | 0:05:39 | |
Whether it's a quick dash in for the essentials or a big trip to | 0:05:39 | 0:05:42 | |
buy the family groceries, you might think that what we choose to put into our baskets | 0:05:42 | 0:05:46 | |
is entirely up to us. | 0:05:46 | 0:05:48 | |
But you'd be wrong. | 0:05:48 | 0:05:50 | |
So when consumers are out shopping, they use lots of intuition, | 0:05:50 | 0:05:54 | |
lots of emotions, | 0:05:54 | 0:05:55 | |
and retailers are really trying to tap into those | 0:05:55 | 0:05:59 | |
mental short cuts that people have, that consumers have, | 0:05:59 | 0:06:02 | |
and really what they're trying to do is increase perceptions of quality | 0:06:02 | 0:06:06 | |
or perceptions of taste of products by tapping in to those mental short cuts. | 0:06:06 | 0:06:11 | |
So, we're going to reveal how they do it, why they do it and whether we REALLY fall for it. | 0:06:11 | 0:06:19 | |
Taking price out of the equation, the key battle ground for quality | 0:06:19 | 0:06:22 | |
and trust is not necessarily what's in the product, but what's on | 0:06:22 | 0:06:25 | |
the outside - the packaging. | 0:06:25 | 0:06:27 | |
So, for our test, we're going to be designing our own. | 0:06:27 | 0:06:30 | |
One of the recent trends in packaging is transparent packaging, | 0:06:30 | 0:06:34 | |
the ability for consumers to actually see the product. | 0:06:34 | 0:06:38 | |
This is a really effective way of influencing consumers simply because | 0:06:38 | 0:06:42 | |
when they're able to see the product they're able to actually imagine | 0:06:42 | 0:06:46 | |
either tasting or using that product. | 0:06:46 | 0:06:49 | |
So that's exactly what we're going to do with our first product. | 0:06:49 | 0:06:55 | |
Although these two packets of biscuits look very similar, | 0:06:55 | 0:06:58 | |
we're giving one of them a window, so shoppers can see the biscuits on the inside. | 0:06:58 | 0:07:02 | |
Now, what happens when people pass these sorts of packaging | 0:07:02 | 0:07:06 | |
is that they barely noticing the non see-through one, but they are much | 0:07:06 | 0:07:09 | |
more likely to stop on the see-through packaging. | 0:07:09 | 0:07:13 | |
Next, how the product is described - cue our version of a convenience lasagne. | 0:07:13 | 0:07:19 | |
More and more, retailers will use very specific language to describe products. | 0:07:19 | 0:07:24 | |
This could be things like "home-made", like "premium", or "luxury". | 0:07:24 | 0:07:29 | |
These sorts of words trigger positive memories, | 0:07:29 | 0:07:32 | |
positive associations, which again are related to quality. | 0:07:32 | 0:07:36 | |
So this simple beef lasagne becomes | 0:07:36 | 0:07:38 | |
"Luxury Select Beef Lasagne, | 0:07:38 | 0:07:41 | |
"with a rich tomato ragu and a creamy bechamel sauce." | 0:07:41 | 0:07:45 | |
Delicious. | 0:07:45 | 0:07:47 | |
But why stop there? | 0:07:47 | 0:07:50 | |
Another interesting element that retailers use on packaging is sense of place, | 0:07:50 | 0:07:54 | |
the origins of the product. It could be things like | 0:07:54 | 0:07:57 | |
Italian home-made or authentic Indian or from a Scottish farm, for instance, | 0:07:57 | 0:08:02 | |
so that particular sense of place gives an authenticity to the product | 0:08:04 | 0:08:08 | |
and perceptions of quality of that product and therefore consumers are more likely to choose it, as well. | 0:08:08 | 0:08:14 | |
So, for our final product, we're transforming a simple pork sausage | 0:08:14 | 0:08:20 | |
into one from a rural idyll of Cottage Lane Farm. | 0:08:20 | 0:08:24 | |
And where is that, you might ask? | 0:08:24 | 0:08:25 | |
Well, it doesn't exist. We've made it up. | 0:08:25 | 0:08:28 | |
Just like Marks and Spencer's did with their Lochmuir Salmon. | 0:08:28 | 0:08:32 | |
It may hint at a classic Scottish lake, but there's no such place | 0:08:32 | 0:08:36 | |
as Lochmuir. | 0:08:36 | 0:08:38 | |
And although Oakham, Marks and Spencer's chicken brand, is a real place, | 0:08:38 | 0:08:42 | |
not all the chicken packaged as such comes from there. | 0:08:42 | 0:08:46 | |
The same is true of Willow Farm, from Tesco. | 0:08:46 | 0:08:49 | |
Even though it's not real, consumers are unaware of this | 0:08:49 | 0:08:53 | |
and they will still associate the same type of quality and the same type | 0:08:53 | 0:08:57 | |
of trustworthiness as the real places. | 0:08:57 | 0:09:00 | |
And it's perfectly legal. Supermarkets CAN invent a place like this for marketing purposes. | 0:09:00 | 0:09:06 | |
Tesco says they use British chickens from a number of different farms, one of which is called Willow Farm. | 0:09:06 | 0:09:13 | |
Marks and Spencer's told us that Oakham chickens come from UK farms | 0:09:13 | 0:09:17 | |
with both the name of the farmer and the county where the bird has been | 0:09:17 | 0:09:21 | |
reared listed on the pack. | 0:09:21 | 0:09:22 | |
They add that all Lochmuir fish sold is Scottish and on most products | 0:09:22 | 0:09:27 | |
they also list the name of the loch where it is sourced. | 0:09:27 | 0:09:30 | |
I would be very surprised that Lochmuir's not a real place, what have they put it on there for? | 0:09:30 | 0:09:34 | |
If the chicken is not from Oakham, why do you use this name? | 0:09:34 | 0:09:39 | |
So, we've now seen some of the techniques we're exposed to every time we go shopping. | 0:09:39 | 0:09:45 | |
What we really want to know is how effective they are. | 0:09:45 | 0:09:48 | |
So we're going to put our specially designed products through their | 0:09:48 | 0:09:52 | |
paces with a group of volunteer shoppers - will the psychology work | 0:09:52 | 0:09:55 | |
on them? Find out later. | 0:09:55 | 0:09:58 | |
Now, chemicals are all around us. And it's a difficult area to control and regulate. | 0:10:02 | 0:10:07 | |
From cosmetics to sofas, it seems you never quite know where the next allergic reaction could come from. | 0:10:07 | 0:10:14 | |
At least, that's what we've discovered on Watchdog. Here's Lynn Faulds Wood. | 0:10:14 | 0:10:18 | |
'Welcome to Watchdog. In tonight's programme, all these people have written to us.' | 0:10:21 | 0:10:27 | |
'With the new Lemon Fresh Fairy, you've got all the sense of Fairy, all the scent of lemon.' | 0:10:27 | 0:10:33 | |
Fairy liquid - over the years the ads told us it was mild and green. | 0:10:33 | 0:10:39 | |
But as Watchdog discovered in 1996, | 0:10:39 | 0:10:43 | |
the later, lemon versions could cause severe allergic reactions. | 0:10:43 | 0:10:48 | |
It's like a burning feeling, at times. When I put my hand | 0:10:48 | 0:10:51 | |
in cold water, it cools it down, but when I put my hand in hot water, | 0:10:51 | 0:10:54 | |
it really burns again. | 0:10:54 | 0:10:57 | |
Lemon Fairy had an acidity about it which was great for dishes, | 0:10:57 | 0:11:01 | |
but according to some viewers, it could be painful for hands. | 0:11:01 | 0:11:06 | |
After that first report, Watchdog heard from many more of you. | 0:11:06 | 0:11:12 | |
In fact, over 200 people got in touch about old and new versions of Lemon Fairy. | 0:11:12 | 0:11:19 | |
After Watchdog took sufferers to try to meet him, | 0:11:19 | 0:11:21 | |
the dermatologist advising Fairy's parent company, Procter and Gamble, | 0:11:21 | 0:11:26 | |
finally admitted that hundreds more could be affected. | 0:11:26 | 0:11:30 | |
I would reckon about 6% of our population are sensitive | 0:11:30 | 0:11:35 | |
to the kind of damage that fat extraction by a detergent can do to their skin. | 0:11:35 | 0:11:43 | |
The tests we have done seem to show that it is less damaging to hands than other people's products. | 0:11:43 | 0:11:51 | |
As a result of Watchdog's campaign, Fairy and other manufacturers put | 0:11:51 | 0:11:56 | |
warning labels for people with sensitive skin on the back of their products. | 0:11:56 | 0:12:00 | |
Fairy say their formula has been scientifically proven to be safe, | 0:12:00 | 0:12:05 | |
so no change was made to the formulation, although over time, | 0:12:05 | 0:12:08 | |
improvements have been made. | 0:12:08 | 0:12:11 | |
But nine years later, Watchdog was encountering worse problems with hair dyes. | 0:12:11 | 0:12:16 | |
The pictures you've sent us are not a pretty sight. | 0:12:16 | 0:12:20 | |
This is Keely Not, before she dyed her hair. | 0:12:20 | 0:12:24 | |
This is the horror picture afterwards. | 0:12:24 | 0:12:28 | |
This is Lara Danson before dying her hair. | 0:12:28 | 0:12:30 | |
Here's what happened. | 0:12:32 | 0:12:34 | |
They were all reacting to a chemical called PPD. | 0:12:34 | 0:12:38 | |
PD is a toxic chemical found in black rubber, photocopy ink and petrol. | 0:12:38 | 0:12:45 | |
It's also found in most modern hair dyes, | 0:12:45 | 0:12:48 | |
at the hairdressers and in home kits. | 0:12:48 | 0:12:51 | |
Yes, a toxic chemical that companies weren't making a big effort to warn people about. | 0:12:51 | 0:12:57 | |
Following Watchdog's reports, manufacturers did agree to put bigger warnings on packs. | 0:12:57 | 0:13:03 | |
But why do these problems keep happening? | 0:13:03 | 0:13:07 | |
The prime culprits are the preservatives, | 0:13:07 | 0:13:12 | |
the fragrance chemicals and the hair dyes. | 0:13:12 | 0:13:16 | |
All powerful chemicals, that for some products, manufacturers say they can't do without. | 0:13:16 | 0:13:22 | |
The trick is to keep exposure to problematic substances as low as | 0:13:22 | 0:13:26 | |
possible, so that they are effective | 0:13:26 | 0:13:31 | |
in whatever role they have, | 0:13:31 | 0:13:33 | |
but, at the same time, minimising the risk to the consumer. | 0:13:33 | 0:13:39 | |
But there are some chemicals that cause reactions that CAN be removed. | 0:13:41 | 0:13:45 | |
And it would take Watchdog to make that happen, too. | 0:13:45 | 0:13:49 | |
In 2013, over 150 viewers contacted Watchdog | 0:13:49 | 0:13:54 | |
to complain about reactions they'd suffered after using Piz Buin. | 0:13:54 | 0:13:58 | |
Sophie Holmes used the cream for the first time on her face while skiing. | 0:13:58 | 0:14:03 | |
It got worse and worse and started to swell on my face and neck. | 0:14:03 | 0:14:08 | |
So I went straight to A&E in London. | 0:14:08 | 0:14:11 | |
They prescribed me with steroids, to reduce the swelling, because there | 0:14:11 | 0:14:16 | |
was a worry it was restricting my airways and could become fatal. | 0:14:16 | 0:14:21 | |
She was allergic to a chemical known as Methylisothiazolinone, otherwise known as MI. | 0:14:21 | 0:14:27 | |
It turned out dermatologists were seeing far more people | 0:14:27 | 0:14:31 | |
with allergies to MI than would ordinarily be acceptable. | 0:14:31 | 0:14:35 | |
Allergy to it is now at epidemic proportions in the United Kingdom, | 0:14:37 | 0:14:40 | |
such that, at the present time, about 10% of patients | 0:14:40 | 0:14:43 | |
we investigate are now allergic to Methylisothiazolinone. | 0:14:43 | 0:14:48 | |
After Watchdog investigated, the owners of Piz Buin, Johnson and Johnson, announced MI would be | 0:14:48 | 0:14:54 | |
removed from the formula. | 0:14:54 | 0:14:56 | |
Other brands followed suit. | 0:14:56 | 0:14:59 | |
Now, you might be careful about what you put on your skin, | 0:14:59 | 0:15:03 | |
especially after seeing stories like that, | 0:15:03 | 0:15:05 | |
yet one of our more shocking cases of chemicals causing reactions | 0:15:05 | 0:15:10 | |
came from a completely-unexpected source. | 0:15:10 | 0:15:13 | |
In 2008, the programme investigated complaints about sofas | 0:15:16 | 0:15:21 | |
giving people severe rashes. | 0:15:21 | 0:15:23 | |
The sofas were bought at three high street stores, | 0:15:23 | 0:15:26 | |
but made by a Chinese company. | 0:15:26 | 0:15:28 | |
I came out in an awful, awful rash, with huge blisters, | 0:15:30 | 0:15:36 | |
and it was very painful and sore. | 0:15:36 | 0:15:39 | |
It felt like... 50% of my body was burnt. | 0:15:39 | 0:15:44 | |
Tracey was in and out of hospital for six months, | 0:15:44 | 0:15:48 | |
going through surgical biopsies, morphine and low-level chemotherapy. | 0:15:48 | 0:15:54 | |
When she got home, she'd just collapse on the sofa, | 0:15:54 | 0:15:57 | |
exhausted by the pain. | 0:15:57 | 0:15:58 | |
Tracey finally worked out she was actually reacting | 0:15:58 | 0:16:03 | |
to something in her sofa. | 0:16:03 | 0:16:05 | |
Her problem cleared up when she got rid of it. | 0:16:05 | 0:16:08 | |
As Watchdog revealed, the cause was a small sachet of fungicide, | 0:16:08 | 0:16:13 | |
put in to protect the fabric. | 0:16:13 | 0:16:15 | |
It should never have been in the sofa in the first place. | 0:16:15 | 0:16:18 | |
This might amaze you... There are currently controls | 0:16:20 | 0:16:24 | |
on some 30,000 ingredients and even more that are banned. | 0:16:24 | 0:16:28 | |
So whether it's in sofas or sun creams, we may not know | 0:16:28 | 0:16:32 | |
where the next potentially-harmful chemical will appear. | 0:16:32 | 0:16:35 | |
What we do know is, thanks to the regulators, | 0:16:35 | 0:16:38 | |
the products we use today are much safer. | 0:16:38 | 0:16:42 | |
Now, kettles - you can spend as little as £5 or as much as £195. | 0:16:46 | 0:16:52 | |
They all boil hot water, so why IS there such a price range? | 0:16:52 | 0:16:56 | |
Is it all in the look | 0:16:56 | 0:16:57 | |
or do some justify a higher price tag for performance? | 0:16:57 | 0:17:02 | |
Well, a man who has tested all kinds of kettles on the market | 0:17:02 | 0:17:05 | |
is Richard Headland, from Which? | 0:17:05 | 0:17:07 | |
Now, nice cup of tea here, made with a £5 kettle. | 0:17:07 | 0:17:10 | |
If we'd spent £195 on our kettle, would it have made much difference? | 0:17:10 | 0:17:15 | |
Chances are, Sophie, | 0:17:15 | 0:17:16 | |
it wouldn't have made much difference to the end result. | 0:17:16 | 0:17:20 | |
We've still got a cup of tea, but what you may want to consider is how | 0:17:20 | 0:17:24 | |
quickly your kettle is going to boil. The slowest kettles in our test | 0:17:24 | 0:17:28 | |
take around two minutes slower to boil a litre of water | 0:17:28 | 0:17:31 | |
than the fastest ones. So, a big difference. | 0:17:31 | 0:17:33 | |
There's also a big difference in noise. | 0:17:33 | 0:17:35 | |
That's a big bug-bear people have. | 0:17:35 | 0:17:38 | |
If you spend more money on your kettle, will that mean | 0:17:38 | 0:17:41 | |
-your kettle will last longer? -Not necessarily. | 0:17:41 | 0:17:43 | |
You find some cheaper brands that last for ages. | 0:17:43 | 0:17:47 | |
You find some expensive brands that don't last so long. | 0:17:47 | 0:17:49 | |
Ultimately, a kettle is going to give up on you at some point - | 0:17:49 | 0:17:52 | |
the element's going to fail. | 0:17:52 | 0:17:54 | |
I wouldn't spend more if you're looking for durability. | 0:17:54 | 0:17:57 | |
If you want to save money on energy bills, | 0:17:57 | 0:17:59 | |
you should think about how much you are filling your kettle, | 0:17:59 | 0:18:02 | |
-because it does make a difference? -That's probably the thing | 0:18:02 | 0:18:04 | |
that will make the biggest difference to your energy bills. | 0:18:04 | 0:18:06 | |
So, if you are boiling, say, a litre of water, which is about | 0:18:06 | 0:18:09 | |
enough for four cups of tea, doing that five times a day, | 0:18:09 | 0:18:12 | |
over a year, that's going to cost you more than £31. | 0:18:12 | 0:18:15 | |
If you were just boiling enough for one cup of tea, | 0:18:15 | 0:18:18 | |
that would cost you around £10 over the year, so quite a big difference. | 0:18:18 | 0:18:21 | |
One thing to remember is, very often, | 0:18:21 | 0:18:24 | |
you're paying a higher price simply for the look - | 0:18:24 | 0:18:26 | |
-for the style, for the elegance, perhaps? -Absolutely. | 0:18:26 | 0:18:29 | |
There's no reason why you can't spend £10 or less | 0:18:29 | 0:18:32 | |
for an own-brand kettle. Indeed, in our tests, | 0:18:32 | 0:18:36 | |
there are loads of best buys for, sort of, £20 upwards, | 0:18:36 | 0:18:39 | |
-so well worth considering. -Richard, thank you. | 0:18:39 | 0:18:42 | |
Earlier, we saw some of the methods manufacturers use | 0:18:46 | 0:18:50 | |
to try to influence what we buy. | 0:18:50 | 0:18:52 | |
So we've designed our own packaging and set up our own supermarket, | 0:18:52 | 0:18:56 | |
to see if those marketing tricks really work. | 0:18:56 | 0:18:59 | |
Now, all we need are some customers. | 0:18:59 | 0:19:02 | |
Yes, Sophie, and here they are - | 0:19:04 | 0:19:06 | |
eight randomly-selected supermarket shoppers - | 0:19:06 | 0:19:09 | |
to whom we've given a simple shopping list of items to buy. | 0:19:09 | 0:19:12 | |
Our shop is stocked up with two choices for each | 0:19:12 | 0:19:15 | |
of the shopping items on the list, | 0:19:15 | 0:19:16 | |
including the three products that have had our shopping psychology | 0:19:16 | 0:19:20 | |
treatment - the biscuits with the see-through versus closed packets, | 0:19:20 | 0:19:23 | |
our elaborately-described versus simple lasagne | 0:19:23 | 0:19:27 | |
and our standard versus Cottage Lane Farm sausages. | 0:19:27 | 0:19:30 | |
Will our volunteers be influenced by our sneaky packaging? | 0:19:30 | 0:19:34 | |
First up, our biscuits. | 0:19:34 | 0:19:37 | |
I'm a big fan of actually being able to see what I'm going to buy | 0:19:37 | 0:19:40 | |
and these, they look nice. | 0:19:40 | 0:19:42 | |
I like it when I see it, cos then I get what I expect. | 0:19:42 | 0:19:44 | |
I'm going to go for these ones. It's just like a try before you buy - | 0:19:44 | 0:19:48 | |
if you see it, you're more likely to buy it. | 0:19:48 | 0:19:50 | |
An impressive seven out of eight plumped for the product | 0:19:50 | 0:19:53 | |
that had the biscuits on display. So, no surprise there. | 0:19:53 | 0:19:57 | |
When our volunteers see these packages, | 0:19:57 | 0:20:00 | |
when they see the see-through packaging in particular, | 0:20:00 | 0:20:02 | |
they are likely to have a chemical reaction. | 0:20:02 | 0:20:06 | |
The chemical dopamine is likely to be released, | 0:20:06 | 0:20:08 | |
which kind of triggers this sort of reward and pleasure system, | 0:20:08 | 0:20:12 | |
which we will feel when we actually eat the product, | 0:20:12 | 0:20:14 | |
so they're simulating eating | 0:20:14 | 0:20:16 | |
when they're actually seeing that particular product. | 0:20:16 | 0:20:19 | |
What about our ready meal? | 0:20:19 | 0:20:20 | |
Which is the most likely to make the dining table? | 0:20:20 | 0:20:23 | |
Remember, one of these isn't just beef lasagne, | 0:20:23 | 0:20:26 | |
it's a luxury beef lasagne with a rich ragu and creamy bechamel sauce. | 0:20:26 | 0:20:31 | |
So, that sounds very, very good. It's luxury. | 0:20:31 | 0:20:37 | |
Mm. | 0:20:37 | 0:20:38 | |
OK, they look pretty similar but I do like the lingo on that. | 0:20:38 | 0:20:42 | |
This time, five out of eight went for our more descriptive version. | 0:20:42 | 0:20:47 | |
Now, I was, of course, expecting this to happen, | 0:20:47 | 0:20:49 | |
but it really never ceases to surprise me how small changes | 0:20:49 | 0:20:53 | |
to the packaging, such as words, can have such a big effect on consumers. | 0:20:53 | 0:20:58 | |
And finally, our mythical farm sausage also came out on top, | 0:21:01 | 0:21:04 | |
with six out of eight opting for the Cottage Lane version. | 0:21:04 | 0:21:07 | |
Cottage Lane, I will choose the Cottage Lane. | 0:21:07 | 0:21:10 | |
It's, basically, showing me where my product has been sourced from | 0:21:10 | 0:21:14 | |
and it's got a picture of the farm here. | 0:21:14 | 0:21:17 | |
The pigs are going there on the farm and not in a factory. | 0:21:17 | 0:21:22 | |
I'm assuming that if the pigs came from this lovely place | 0:21:22 | 0:21:25 | |
then they probably taste nice, too. | 0:21:25 | 0:21:27 | |
So it's clear, we're all open to the influence of the supermarket | 0:21:29 | 0:21:32 | |
tricks, whether we realise it or not. Even Gorkan, it seems. | 0:21:32 | 0:21:37 | |
What never really ceases to surprise me is the fact that | 0:21:37 | 0:21:41 | |
I know all this stuff and yet I'm still influenced by it. | 0:21:41 | 0:21:44 | |
'I simply cannot control it myself.' | 0:21:44 | 0:21:47 | |
It's very difficult to do anything about them. | 0:21:47 | 0:21:50 | |
Back now to dishwashers and earlier we heard how household | 0:21:53 | 0:21:57 | |
appliances were responsible for thousands of fires last year. | 0:21:57 | 0:22:01 | |
Well, here at the Building Research Establishment | 0:22:01 | 0:22:03 | |
teams of specialists are working hard to find out what causes | 0:22:03 | 0:22:07 | |
such fires and how to prevent them. | 0:22:07 | 0:22:09 | |
This is their fire testing facility, the largest of its kind in Europe. | 0:22:10 | 0:22:16 | |
They work alongside Fire Investigations UK to provide | 0:22:16 | 0:22:19 | |
vital information once a fire has happened. | 0:22:19 | 0:22:22 | |
It can be crucial evidence that can save lives. | 0:22:22 | 0:22:25 | |
Our remit is to identify the origin of the fire, | 0:22:25 | 0:22:29 | |
where a fire started and what caused the fire. | 0:22:29 | 0:22:33 | |
'When we do a full-scale reconstruction it's to replicate | 0:22:33 | 0:22:36 | |
'how that fire developed in the real circumstances' | 0:22:36 | 0:22:39 | |
and that's what we're going to try and show you here today. | 0:22:39 | 0:22:42 | |
They need to rig this dishwasher with a simple fault, | 0:22:42 | 0:22:45 | |
something that could occur on any machine. | 0:22:45 | 0:22:47 | |
'When appliances are moved around a lot, | 0:22:48 | 0:22:51 | |
'perhaps if they've moved from one property to another and | 0:22:51 | 0:22:54 | |
'they haven't been handled carefully, you could get a loose connection.' | 0:22:54 | 0:22:58 | |
If you don't have a tight connection on some of these high energy | 0:22:58 | 0:23:02 | |
electrical conductors, it will create resistance at that point | 0:23:02 | 0:23:07 | |
and it will start to glow, like a small electric heater. | 0:23:07 | 0:23:11 | |
'If there's plastic around it then it can ignite the plastic | 0:23:11 | 0:23:15 | |
'or any other combustible material.' | 0:23:15 | 0:23:17 | |
When they do catch fire then there's normally quite a serious consequence. | 0:23:17 | 0:23:22 | |
The kitchen is constructed ready for the fire | 0:23:22 | 0:23:25 | |
and Peter replicates the loose connection fault on our dishwasher. | 0:23:25 | 0:23:29 | |
Everything is set for the reconstruction. | 0:23:29 | 0:23:32 | |
Let the fire commence. | 0:23:32 | 0:23:34 | |
Five, four, three, two, one. | 0:23:34 | 0:23:38 | |
Ignition. | 0:23:38 | 0:23:41 | |
So here we're simulating a fault within the dishwasher, | 0:23:41 | 0:23:44 | |
for instance a bad connection, which would result in resistance heating. | 0:23:44 | 0:23:49 | |
The electrical connection heats up | 0:23:49 | 0:23:51 | |
and ignites the plastic within the appliance. | 0:23:51 | 0:23:54 | |
A pilot flame is created and the dishwasher is now on fire. | 0:23:54 | 0:23:58 | |
We're a minute in and there's enough smoke | 0:23:58 | 0:24:00 | |
to activate the smoke detector. | 0:24:00 | 0:24:01 | |
SMOKE DETECTOR BLEEPS | 0:24:01 | 0:24:04 | |
We can now see the fire has actually taken hold of the appliance | 0:24:07 | 0:24:10 | |
and it will start to spread to the timber cabinets next door to it. | 0:24:10 | 0:24:15 | |
As the fire develops, the plastic drips onto the floor. | 0:24:18 | 0:24:22 | |
If this were a real fire in a real kitchen the wooden or lino floor | 0:24:22 | 0:24:27 | |
would also go up in flames. | 0:24:27 | 0:24:29 | |
The flames are now starting to reach up into the smoke layer. | 0:24:31 | 0:24:36 | |
You can see the cabinets either side of the dishwasher are starting to | 0:24:36 | 0:24:39 | |
ignite and we're now getting a more rapidly developing fire. | 0:24:39 | 0:24:44 | |
In less than 25 minutes, the temperature on the ceiling | 0:24:45 | 0:24:49 | |
reaches 300C. | 0:24:49 | 0:24:52 | |
The burning cupboards and the worktop are adding fuel to the fire. | 0:24:52 | 0:24:56 | |
MUSIC | 0:24:56 | 0:24:58 | |
And this is when a room starts to develop to flashover, | 0:25:04 | 0:25:07 | |
when the fire in a room becomes a room on fire. | 0:25:07 | 0:25:11 | |
And everything in the room will ignite. | 0:25:11 | 0:25:13 | |
One minute later, almost everything in the room is on fire. | 0:25:13 | 0:25:17 | |
In a real house, with added furnishings, the fire would | 0:25:17 | 0:25:20 | |
reach this intensity even faster. | 0:25:20 | 0:25:23 | |
'And we can see flames developing along the ceiling | 0:25:25 | 0:25:27 | |
'and the radiated heat is quite intolerable.' | 0:25:27 | 0:25:31 | |
OK, thanks for your help. | 0:25:34 | 0:25:36 | |
OK. | 0:25:36 | 0:25:37 | |
The fire is extinguished before it becomes uncontrollable. | 0:25:37 | 0:25:42 | |
'So here we can see the aftermath of what is a relatively small | 0:25:51 | 0:25:55 | |
'and contained fire in a kitchen | 0:25:55 | 0:25:57 | |
'and we can see the devastation that this has caused, and the smoke | 0:25:57 | 0:26:00 | |
'damage would be 100% throughout the property by this stage.' | 0:26:00 | 0:26:05 | |
Fire reconstructions like this are key to understanding how | 0:26:05 | 0:26:09 | |
fires develop, but Fire Investigations UK also attend | 0:26:09 | 0:26:13 | |
the aftermath of real fires, to determine the cause and origin. | 0:26:13 | 0:26:18 | |
So a second fire investigator, John Galvin, is going to take | 0:26:18 | 0:26:21 | |
a look at our burnt-out kitchen, to show us just how it's done. | 0:26:21 | 0:26:25 | |
Now, in this particular room, we can see that the most damaged area | 0:26:26 | 0:26:30 | |
is the far side and we can see on that particular wall, | 0:26:30 | 0:26:34 | |
we have flame impingement and that is an indicator for us that that | 0:26:34 | 0:26:38 | |
area was severely affected by the fire whilst it was in progress. | 0:26:38 | 0:26:42 | |
John is particularly interested in the appliances on the left-hand | 0:26:42 | 0:26:46 | |
side of the kitchen. | 0:26:46 | 0:26:47 | |
'I can see from here, a kettle, a toaster | 0:26:49 | 0:26:51 | |
'and there appears to be some measuring scales at the end.' | 0:26:51 | 0:26:54 | |
Could they actually be part of the cause of this fire? | 0:26:54 | 0:26:57 | |
If this had been a real fire, every appliance in the room would be | 0:26:57 | 0:27:01 | |
examined to determine whether it had been switched on at the time. | 0:27:01 | 0:27:05 | |
If not, it would be eliminated as a potential cause, | 0:27:05 | 0:27:08 | |
but John has already found another clue. | 0:27:08 | 0:27:11 | |
The table has scorching on the side facing what | 0:27:11 | 0:27:14 | |
we believe to be the area of origin. | 0:27:14 | 0:27:15 | |
Additionally we have some shadowing on one of the chairs under the table, | 0:27:15 | 0:27:19 | |
-which shows an area protected by the table leg. -Getting warmer, John. | 0:27:19 | 0:27:25 | |
So all the data we've gathered so far are pointing us | 0:27:25 | 0:27:29 | |
towards this appliance. | 0:27:29 | 0:27:30 | |
So, if I just pop the door open. | 0:27:30 | 0:27:32 | |
What I can see now is that the internal surfaces of this | 0:27:35 | 0:27:39 | |
particular appliance are very heavily coated with smoke deposits. | 0:27:39 | 0:27:43 | |
There's also none of the plastic internal components remaining, | 0:27:43 | 0:27:47 | |
so we can say that this particular appliance has suffered | 0:27:47 | 0:27:50 | |
greatly during this fire. | 0:27:50 | 0:27:52 | |
John quickly suspects that the dishwasher did start the fire. | 0:27:53 | 0:27:57 | |
Next, it would go to the lab, to confirm if he was right. | 0:27:57 | 0:28:01 | |
'Fire investigation gets to the bottom of why fires occur' | 0:28:01 | 0:28:04 | |
and by feeding that information back to the manufacturers we try | 0:28:04 | 0:28:08 | |
'and prevent such things happening again in the future. | 0:28:08 | 0:28:12 | |
'If things happen time and time again and we identify a pattern,' | 0:28:12 | 0:28:15 | |
we may be able to persuade the manufacturer to actually do | 0:28:15 | 0:28:18 | |
a recall or certainly alert members of the public to the | 0:28:18 | 0:28:21 | |
potential of a problem with a particular device. | 0:28:21 | 0:28:25 | |
If you want more information on the safety of products | 0:28:29 | 0:28:32 | |
in your home, you can go to our website. | 0:28:32 | 0:28:35 | |
That's all for today. Thanks for watching. | 0:28:40 | 0:28:43 |
