We have a product that has

the following properties:

Health Safety and Welfare

Virtually indestructible

Fire_proof

Water resistentHeat resistant

Cheap

Natural product mined from the earth

VersatileFibres can be woven into clothing

Can be sprayed over pipes etc to add fire-proofing

Can be added to any product to pass on the properties

Health Safety and Welfare

What uses can you think offfor this type of material ?


3/63


4/63

Aim

Raise the awareness of everyone to

the new duty to manage asbestos inbuildings


5/63

Whats Asbestos all about?

Asbestos is a naturally occurring fibrousmineral, looks a bit like rockwool or

fibreglass in its raw state

It was already in use by the Egyptians

around 2000BC, woven into cloth and usedas a burial shroud.


6/63

Whats Asbestos all about?

The Romans used it and the Fins madecooking pots from it in the first millenium.

In the latter part of the Industrialrevolution its use became common inindustry.

New uses evolved particularly in buildingproducts where its range of propertieswere exploited to the full


7/63


8/63

What was so good about it?

Heat resistant, doesnt start todegrade until about 900 deg C

Doesn't burn

Resistant to acids & corrosion

Can be woven into a strong cloth

Can be used as a reinforcement

similar to fibre glass Cheap & easy to use


9/63

So, whats the problem

The wonderful properties that makeit useful has a big downside if it getsinto the lungs.

The tiny fibres are sharp and strong.

Breath in the fibres and they getstuck in the lung, in fact every timeyou take a breath they get drawndeeper.


10/63

Remember its properties

Resistant to acid and corrosion

Strong

Well, this means that the fibres stayin the lungs and cant be brokendown by the body

They are also sharp and can

penetrate lung tissue.Thats where cancers can start


11/63

Asbestos related diseases

The inhalation of asbestos fibres has been shown tobe the cause of three types of diseases.

Asbestosis

Asbestos Cancers

Mesothelioma


12/63

How big is the problem?

This year around 3000 people will diefrom Asbestos related diseases

By 2020 that may rise to 10,000 per

year Nothing can be done for these

people, these diseases are not

treatable. Can take 5~50 years to show

Horrible death


13/63

Why dont they dosomething?

Most intensive use from 1955 to1970

Which meant that the significanteffects only began to show in 1980s

Legislation was geared to protectingworkers in manufacture and removal

of asbestos


14/63

Jigsaw Puzzle

But the numbers kept rising whenthe should have started to fall

From a study in 1995 it was clearthat 25% of people dying hadpreviously worked in the constructionindustry


15/63


16/63

Then

1998 The Asbestos (Licensing) Regulationswere expanded to include any work doneon asbestos board to be carried out bylicensed contractors

In 1998 Control of Asbestos at WorkRegulations was amended

Expanded scope to include incidentalexposure to asbestos

Made it clear that CAWR applied to allworkers

In 1999 use of all asbestos in manufacturewas banned


17/63

The Heritage

It is almost impossible to destroy it

Thousands of tonnes were used each

year in buildings

Usage peaked 1950~1970

Estimated 2 ~ 4 Million of tonnes arestill left in buildings


18/63


19/63

Just who is at risk?

Anybody that disturbs ACMsufficiently to put dust in the air!

Demolition Workers Building Maintenance Workers

Gas fitters

Joiners

Electricians Heating and ventilating engineers

Plumbers


20/63


21/63

The Dilemma

Huge quantity of asbestos in buildings

To remove it all would cost billions

If removed what can be done with allwaste

Increased risk to all the removers, peoplearound, transport, waste dumps etc


22/63

Asbestos mill board used

as a ceiling board for fire

resistance, plumber didnt

recognise it when he fixed

the leak


23/63

The Good News

2002 Asbestos at Work Regulations amendedfurther and now include

Specific Duty, To Manage Asbestos in Buildings

Duty holder is principally the occupier

Mostly the employer

Housing at the moment excluded


24/63

What the new Duty


25/63

What the new Dutymeans

We have to find out where all asbestos

Risk assess

Decide whether to remove, encapsulate it,

or leave as is Keep register of all asbestos

Monitor its condition

Provide information on the location andcondition of the materials to anyone whois liable to work on or disturb them

What are we doing

Asbestos has always been dealt with according tothe laws

To help us we have employed specialist

consultants

Thoroughly vetted during selection process

One of leading Asbestos Consultants

Advise us on all aspects

Steps taken since 2005

February 05 all data into database

March 05 all data transferred to our

Repairs Management System

Asbestos information will automatically be

included on every job ticket to help keepour partners safe


32/63


33/63

As future construction workers, weask you to help

If you suspect that the information on thejob ticket is wrong tell us immediately

If you suspect asbestos, stop workimmediately and tell us

If you suspect asbestos that does notaffect the job in hand, tell us as soon aspossible
