Asbestos - Legal responsibilities

The James Hardie experience

• People who contract an asbestos related disease will seek financial support from parties responsible for their illness

• Individuals or their dependents may seek compensation through workers’ compensation authorities

• But, contractors remain liable to common law claims for compensation

© MPMSAA 2004 4

FRIABLE material: easily crumbled with finger pressure, (steam pipe lagging) high potential to generate airborne fibres

NON-FRIABLE material: bonded material, (AC sheet) low potential to generate airborne fibres unless cut with power tools

• Non-friable Asbestos containing material (ACM) in good condition and where it is not easily disturbed or damaged is not a health risk

• ACM that is adequately sealed or enclosed is not a health risk• This material has the potential to be a health risk if disturbed or

damaged

“It is like a sleeping dragon if you disturb it; it

can hurt you.”

Asbestos – the product

© MPMSAA 2004 5

What is asbestos?

• Naturally occurring rock• Two families of minerals

• Serpentine • Amphibole

• Occurs as bundles of very fine fibres • Stressing of fibres often results in an increase of

airborne asbestos fibres• Three common types commercially used in

Australia• Blue - Crocidolite• Brown - Amosite • White - Chrysotile

© MPMSAA 2004 6

Working with Asbestos Containing Material

Asbestos Products - Where they were used

• Roofs and walls• Wet areas• Storm and sewerage pipes• Heater and hot water service flues• Mortar• Bituminous membranes• Galbestos• Adhesives & Mastiks• Gaskets, Seals• Roadway Pits

Over 3000 products produced in Australia

© MPMSAA 2004 7

Working with Asbestos Containing Material

How do you identify asbestos containing material?

– Consult the work site record of results (refer building owner/manager)

– Look for asbestos labels

– Take a sample for identification • WorkSafe Asbestos bulletin No. 1, Approved Asbestos Analysts • For identification of asbestos (YES/NO) and for counting airborne

fibres (number of fibres per ml. of air)• The analyst must be NATA approved

– Err on the side of caution and assume that it is ACM.

You can deem it to be asbestos containing material from your knowledge and experience

© MPMSAA 2004 8

Working with Asbestos containing Material

Asbestos cement (AC) building products• Use of Crocidolite (blue) ceased 1968• Sheets and mouldings asbestos free by late 1981• Compressed sheet asbestos-free by late 1983• Corrugated sheet asbestos-free by late 1985

“Use of products containing asbestos largely ceased in the late 1980’s

but use/re-use was not prohibited until Dec 2003.”

© MPMSAA 2004 9

Asbestos - Health Effects

If asbestos products or asbestos containing materials are disturbed, damaged, broken or worked on so that asbestos fibres become airborne it is a potential major health hazard.

A long period of time can occur between first breathing asbestos dust and a disease appearing (latency period)

The diseases are essentially untreatable The emphasis must be on prevention of:

1. Exposure to dust/fibre

2. Inhalation of dust/fibre.

© MPMSAA 2004 10

The basis for the concern• Mortality study - deaths amongst 17,800 asbestos insulation workers, for at least

20 years, who were union members in the USA and Canada, 1967 to 1986 (Selikoff &

Seidman: Annals New York Academy of Sciences)

Cause of Death

Expected no of deaths (normal population)

Observed no of deaths (workers)

Total - all causes 3,453 4,951

Total cancer, all types 761 2,295

Lung cancer 269 1,168

Mesothelioma 0 458

Gastrointestinal cancer 136 189

Pleural Plaques • The pleura is the membrane lining the lung• Plaques are detected by chest X-ray or CAT scan• Pleural plaques are regarded as signs of significant

asbestos exposure over an extended period• They may be associated with some reduction in

lung function, but also may not have any direct health impact

• Latency may be up to 10 years• It is not clear whether they are a precursor to other

asbestos related diseases


© MPMSAA 2004 12

Asbestosis• A “dust disease” where soft and elastic lung

tissue becomes hard and fibrous• Causes difficulty in breathing which can get

worse• Latency period may be 15 to 30 years• Can be fatal• Caused by all forms of asbestos


© MPMSAA 2004 13

Lung cancer• Identical to the disease caused by smoking

• A cancer of the airways in the lung

• Latency period may be 20 years

• Almost always fatal

• Caused by all types of asbestos


© MPMSAA 2004 14

Mesothelioma• A cancer of the lining of the lung, stomach or heart• Usually extremely rare• With asbestos exposure in the last 10 years, 400 to

650 cases in Australia per year• Exposure to asbestos is only known cause• Latency period at least 15 years, can be up to 60

years, • Appears to have been caused by lower exposures

to asbestos


© MPMSAA 2004 15

• “Risk” means the likelihood of illness or disease arising from exposure to airborne asbestos fibres

• Not everyone who is exposed to airborne asbestos fibres gets an asbestos disease

• It is not possible to tell who will get an asbestos disease

Asbestos – Risks

© MPMSAA 2004 16

What must a plumber do in relation to ACM?

Prevent / avoid:• Exposure to airborne asbestos fibres • Potentially creating airborne asbestos fibres

Need to control the risk to:

• Self and family

• Clients and work mates

• Community

Asbestos – Risks

© MPMSAA 2004 17

Some of the factors affecting the risk of getting an

asbestos disease are:

• How much asbestos dust there is in the air being inhaled by the individual

• The total length of time for which the dust is breathed, whether continuously, or over repeated bursts of exposure

• The dimension and concentration of the fibres inhaled

• The age of the person when first exposed

• Whether or not the person smokes

Asbestos – Risks

© MPMSAA 2004 18

How RISK depends on DOSE:—

• If the dose is increased, the risk is increased

• If the dose is reduced, the risk is reduced

• The Asbestos Regulations include a requirement to

reduce exposure to airborne asbestos so far as is

practicable

• Prevent exposure by not generating airborne

asbestos dust

Reduce the risk to you by reducing the DOSE !

Asbestos – Risks

© MPMSAA 2004 19

Plumbers can be potentially exposed to asbestos when they:

• Carry out tasks that require them to handle ACM

eg. Removing ACM flue from space heater or hot water service

• Carry out tasks that have the potential to create airborne asbestos fibres

eg. Create penetrations in AC eaves sheets for pipes

• Work in the vicinity of ACM

eg. Maintenance in a ceiling space where ACM is present

Because asbestos was used for most of the 20th century,

as a component of so many products, nearly all workers will encounter it at some stage of their working lives.

Asbestos – Risks

© MPMSAA 2004 20

How can a plumber be potentially put at risk bycreating airborne dust containing asbestos fibres?

• Not identify ACM

• ACM identified but information not passed on to plumber

• ACM not labeled

• Knew ACM was present but did not follow procedures to control

generation of airborne fibres

• Potentially generated airborne fibres by disturbing asbestos with

mechanical work, power tools or compressed air

ACM in good condition, sealed or enclosed in position where it is not disturbed or easily damaged is not a health risk.

“Remember it is like the sleeping dragon!”

Asbestos Regulations 2003What are the tasks a plumber MUST NOT

undertake unless they are a licenced removalist?

• MUST NOT carry out asbestos removal work beyond the limits set out by the regulations

• Class A & Class B licensed asbestos removalist

• MUST NOT work on friable asbestos• Friable material

– Easily crumbled or reduced to powder by hand pressure (eg steam pipe lagging)

– High potential to generate airborne fibres

© MPMSAA 2004 26


What can a plumber do; who is not a licenced removalist.

They may carry out tasks involving ACM under Part 8 of the Asbestos regulations? Such as:

• Collecting samples of ACM for identification• Transport of ACM for disposal after removal• Removal of ACM; flues, water pipe, AC-sheet, AC roofing and fittings if meet

criteria of Reg. 207• Painting AC sheet• Making a hole in AC sheet/water pipe/road pits (hand tools0• Cutting AC sheet/water pipe (hand tools)• Cleaning AC gutters• Clean up non-friable debris if meet criteria of DG Order• Repairing damaged AC sheet• Work involving bituminous products containing asbestos

Asbestos Regulations 2003

© MPMSAA 2004 27

The Regulations ALLOW plumbers to perform small scale removal subject to the following criteria (Reg. 207):

1. Can only remove non-friable ACM for up to one hour every seven days (per company, must be documented)

2. Work can only involve removal of small amounts of non-friable ACM but conditions apply

I. ACM removal to take less than one hour (per company)II. Can remove up to 10 m2 in area, total area of ACM

i. approximately 4 sheets of AC or roofingii. approximately 4 lengths of AC flue and fittings

3. The work needs to meet the requirements of Part 8

4. If you need to do more than this then you need to become a Class B (Non-friable) removalist

Social & Financial IMPACT to Business

A plumber who is not a licenced removalist and proposes to remove quantities of non-friable ACM permitted under regulation 207 must meet the legal requirements of Part 8 of the Regulations

• Not following the required regulations has potential health costs for:

• SELF and family

• Clients and workmates

• Community

• And has real financial implications:• Insurance exclusion

• Government Regulators prosecution

© MPMSAA 2004 29

Model Insurance Policy Exclusion in relation toliability

This policy section does not insure liability arising directly or indirectly out of or in connection with, or for:

• any mining use, handling, removal, manufacture, processing, distribution, transportation or storage of asbestos or raw material containing asbestos;

• inhalation of asbestos fibres resulting from any process of decontamination, treatment, removal or control of asbestos or materials containing asbestos; or

• loss of, damage to, or loss of use of property, due to the presence of asbestos

Financial Business Impact

© MPMSAA 2004 30

Business and Community Obligation

What must a plumber do who is not a licenced removalist who decides to work on ACM?

– Must control risk of being exposed to airborne asbestos fibres or potentially creating airborne asbestos fibres

– Need to remove risk to:

• Self and family

• Clients and fellow workers

• Community

HOW?

NO AIRBORNE DUST while carrying out the task

At the end of the job there must be – NO VISIBLE DEBRIS left in area

ASBESTOS THE SILENT KILLER

Asbestos containing material (ACM) in good

condition sealed or enclosed in a position where it is

not disturbed or easily damaged is not a health risk.

It has the potential to be a health risk if disturbed,

damaged or worked on.

1. Work in vicinity of ACM– If the ACM is sealed and enclosed, not damaged and your work is not

going to disturb the ACM; must be identified, a record of results completed for workplaces and labeled where practicable.• Working in a work shop with AC walls• Working in boiler room with asbestos lagged pipe work

Asbestos containing material (ACM) in good condition,sealed or enclosed in position where it is not disturbed or

easily damaged is not a health risk.It has the potential to be a health risk if disturbed ordamaged.

(Remember the sleeping dragon)

© MPMSAA 2004 36


2. Work on ACM• Work on ACM that has minimal potential to generate airborne

asbestos fibres is of minimal risk. A risk assessment should be

completed to document this and a work procedure created.• Cleaning AC gutters• Painting AC sheet walls

• Work on ACM that has the potential to generate airborne asbestos fibres is a potential risk. A risk assessment must be completed to document this and procedures established for the work to control the generation of airborne asbestos fibres.– Cutting AC water pipe– Creating holes in AC sheet

© MPMSAA 2004 37


3. Small scale removal of ACM• Removal of ACM has the potential for damage to

occur and creating airborne asbestos fibres.

• A risk assessment must be completed to document this and procedures established for the work to control the generation of airborne asbestos fibres.

– Removing a flue from a gas appliance– Removing a burst piece of AC water pipe

Questions to be asked before you start the job Is it asbestos containing material? YES

3 options

• Consult the site record of results if it is a workplace

• Take sample for identification• WorkSafe Asbestos Bulletin No 1, Approved Asbestos

Analysts

• Analysts must be NATA approved

• Err on the side of caution and assume that it is ACM

© MPMSAA 2004 39


Is it friable ? YES

• "friable" means, when dry, may be crumbled, pulverised or reduced to powder by hand pressure, or as a result of a work process becomes such that it may be crumbled, pulverised or reduced to powder by hand pressure;

• CANNOT remove and DO NOT undertake the work unless a Class A removalist is used. • Refer to WorkSafe web site to get list of Class A removalists

© MPMSAA 2004 40


Does task to be carried out involve removal of non-friable ACM?• Is the area of ACM greater than 10m2

• Is going to take longer than one hour?• Have you or any other employee in your company done any work in

the last 7 days which required the removal of ACM? • Will the total time spent removing ACM for you or your company

exceed one hour?

If YES to any of the above questions

Class B removalists are required to carry out the task and you cannot

do the jobAs you can only remove non friable ACM for up to one hour every seven days

(per company)

Refer to WorkSafe web site for list of Class B removalists

© MPMSAA 2004 41


If you are still going to carry out the task involving

ACM

• Need to conduct a Risk assessment on the task to be carried out – Can be generic

• Need to have procedure to carry out task involving ACM– To establish measures taken to control risk of generating

airborne asbestos fibres

Procedure for creating a hole in ACM

Options to consider:

• Remove if practicable and replace ACM sheet that

requires hole with asbestos free sheet

• Create hole from above using hand tools

• Create hole from above using hand drill

• Create hole from below using hand tools

• A powered drill can only be used if airborne dust levels

are controlled to ensure a person is not likely to exceed

0.05 f/ml during the task, using an enclosure or

engineering controls as required under Reg 305
