Asbestos facts l.jpg

Asbestos Facts


Slide4 l.jpg

Asbestos Facts

  • Asbestos is a naturally occurring mineral

  • It belongs to the silicate family of minerals

    • Fibrous

    • Non-Fibrous

Seven times stronger than steel

Chemically resistant (acids, bases, peroxides)

Does not conduct heat or electricity

Good noise insulation properties


Slide5 l.jpg

Asbestos Facts

Two Familial Forms of Fibrous Asbestos

Asbestos

Serpentine

Amphibole

Chrysotile

Amosite

Crocidolite

Anthophylite

Tremolite

Actinolite


Slide6 l.jpg

Asbestos Facts

Respirable Asbestos Fibres

Since respirable fibres are so small, less than 5 micrometers in diameter, they are invisible to the naked eye

They fall very slowly – a fibre released at the ceiling in a normal room will take about 10 hours to reach the floor

Respirable asbestos fibres behave more like a gas and are difficult to control

Asbestos Facts

Asbestos Health Hazards

  • Lung Cancer

  • Mesothelioma


Slide8 l.jpg

Asbestos Facts

Continuing Health Hazard

Around 4000 people die each year from asbestos- related diseases

This number has not yet reached a peak

Working conditions are now much improved

No one can be sure just how quickly the numbers are going to diminish


Slide9 l.jpg

Asbestos Facts

Is there Asbestos in my buildings?

Asbestos was used extensively in buildings between the 1940’s and 1980’s (Construction and Refurbishment)

Estimated 2 million premises contain ACMs

Thousands of tons of ACMs still in place

Crocidolite & Amosite use banned in 1985

Chrysotile use banned in 2000

(Not just buildings)


Slide11 l.jpg

Typical Asbestos Locations

in Buildings

Roof

Fire Doors

Pipe insulation

Ceiling tiles

Wall Boards

Service risers

Flooring


Slide12 l.jpg

Asbestos Facts

Asbestos Containg Materials (ACMs)

Some ACMs are more hazardous than others...

How hazardous an ACM is depends on:

How easily fibres are released from the material

How much asbestos fibre is in the material

The condition of the material


Slide13 l.jpg

Asbestos Facts

Asbestos Containg Materials (ACMs)

How can asbestos be released into the air?

If it is disturbed

Coatings are brushed against or bumped

Asbestos boards are cut, drilled, broken or damaged

Asbestos ceiling tiles are cut, drilled, broken

Asbestos cement is cut, drilled, broken

Existing debris is disturbed


Slide14 l.jpg

ACM Type

Hazard Level

Asbestos Facts

Why?

Relatively high asbestos content in a brittle / friable material

Sprayed Asbestos / Asbestos Boarding in very poor condition

Asbestos Insulation Boarding / Pipe lagging

In good condition presents a low hazard but often deteriorates

Cements and plastics don’t easily release the fibres

Cements / plastics / bitumen


Control of asbestos regulations 2006 car 2006 l.jpg

Control of Asbestos Regulations (2006)(CAR 2006)


Slide16 l.jpg

CAR 2006

Historically…

Regulations were brought in to reduce exposure for asbestos workers (Factory Acts)

Attention then turned to those workers removing asbestos

Now applied to all work including incidental exposure to asbestos

Requires the prevention of exposure to asbestos

Require a risk assessment


Slide17 l.jpg

CAR 2006

Control of Asbestos Regulations 2006

  • Apply to all the asbestos minerals

  • An exercise in simplification

    • CAWR2002

    • Prohibition Regulations

    • Licensing Regulations


Slide18 l.jpg

CAR 2006

Main Emphasis

Licensed work with asbestos coating, insulation materials and insulation boards

Contractors who work with asbestos must have an HSE Licence

Outlines certain exemptions for “Minor Works”

Use of asbestos absolutely prohibited by the EU 2003 Asbestos Worker Protection Directive


Slide19 l.jpg

CAR 2006

Minor Works – Regulation 3(2)

“Work of Sporadic and Low intensity”

Only the simplest of jobs

Exposure below 0.6 f/ml over 10 mins

Or: Short duration - one person carries out work for less than one hour in a seven-day period. (total time spent by all workers on the work not exceeding a total of two hours)

All Other Jobs:

HSE Licensed and Notifiable


Slide20 l.jpg

CAR 2006

Risk Assessment & Plans of Work – Regulations 6 & 7

  • Where any work with asbestos is planned a risk assessment must be carried out to determine

    • The type of asbestos

    • The likely level of exposure

    • The control measures needed

  • Written plan of work (method statement) that must be followed


Slide21 l.jpg

CAR 2006

Licensing & Notification of Work - Regulations 8 & 9

Licenses limited to 3 years max

HSE can shorten but not extend the licenses

Exemption for work with asbestos on your own premises / with own employees is removed

HSE / Local council notified 2 weeks in advance of commencement of work


Slide22 l.jpg

CAR 2006

Information, Instruction, Training & Supervision – Regulation 10

  • Large emphasis on asbestos training

  • Covers all levels Operative – Management

  • Training for licensable & non-licensable work

  • Competencies of those delivering training

  • Traceable certification valid for no more than 1 year


Slide23 l.jpg

CAR 2006

Duty to Manage – Regulation 4

  • Asbestos in the non-domestic premises

  • Consider likelihood of ACM presence

  • Identification, Assess Risk, Management Plan

    • Condition assessment; Policies / Procedures for work; Emergencies

  • Emphasis on Control through Awareness

  • Plan recorded & enforced


Duty to manage asbestos car 2006 regulation 4 l.jpg

Duty to Manage Asbestos(CAR 2006, regulation 4)


Duty to manage asbestos l.jpg

Duty to Manage Asbestos

The duty holder:

  • Owners of buildings

  • Occupiers of buildings

  • Facilities management companies

  • Those in charge of buildings


Duty holders will have to l.jpg

Duty holders will have to:

Duty to Manage Asbestos

  • Find out if there is asbestos, how much

    and where

  • Presume unknown materials are ACMs

  • Make and keep a record of the location and condition of ACMs/presumed ACMs

  • Assess the risks from ACMs


Dutyholders will have to cont l.jpg

Dutyholders will have to (cont):

  • Prepare a written management plan

  • Implement the plan

  • Provide information on the location and condition of the ACMs

  • Monitor and review the plan


Slide28 l.jpg

Duty to Manage Asbestos

Maintenance and building trades-people may have been exposed to asbestos when;

They didn’t know that it was asbestos they were working on

They had little or no information about asbestos

The Control of Asbestos Regulations 2006 require those in charge of buildings to identify where asbestos is present and prevent exposure


Slide29 l.jpg

Management Principles

Who is at risk?

Anybody who inhales airborne respirable asbestos fibres

If fibres are not released, there is no disease risk


Managing asbestos l.jpg

Managing Asbestos

  • Duty is to manage asbestos

  • It requires an assessment to be made

  • Not a duty to survey although a survey may be needed

  • Steps required are those that are ‘reasonable’

  • Useful start: ask ‘What am I doing now to manage the risk?’

  • Aim is to protect maintenance workers


Identifying asbestos l.jpg

Identifying Asbestos

  • Presume asbestos:

    - carry out own inspection?

    - engage others to undertake survey

  • Establish identity by sampling or;

  • Conclude it is not asbestos (requires strong evidence) or;

  • A combination of all the above


Developing a management plan l.jpg

Developing a Management Plan

Find out if asbestos is present, how

much there is and in what condition


Developing a management plan33 l.jpg

Developing a Management Plan

Decide what type of inspection or survey

needs to be carried out

Depends on:

  • Use of the Building

  • Age of the Building

  • Refurbishment Plans


Asbestos surveys l.jpg

Asbestos Surveys

HSG 264

Asbestos: The Survey Guide


Asbestos survey l.jpg

Asbestos Survey

HSG 264 gives guidance to those

carrying out surveys and includes:

  • How to recognise and sample

  • How to assess their condition

  • Two types of survey

    • Management – presumptive with some sampling and risk assessment (a combination of the old Type 1 and 2)

    • Demolition - quantitative for demolition / refurbishment (Type 3)


Developing a management plan36 l.jpg

Developing a Management Plan

Decide who will carry out the inspection

or survey

  • Consider training and competency issues

  • Asbestos survey companies who have United Kingdom Accreditation Scheme (UKAS) accreditation


Developing a management plan37 l.jpg

Developing a Management Plan

Make and keep a record of the location and

condition of the ACMs/presumed ACMs


Developing a management plan38 l.jpg

Developing a Management Plan

Assessing the risks: the material assessment

(NB Asbestos is only harmful if fibres are released

into an area where they can be inhaled)

The material assessment quantifies the hazard

from the material, i.e. “how likely is airborne fibre

release if disturbed?”


Developing a management plan39 l.jpg

Developing a Management Plan

Prepare a detailed written plan of how to manage the risk

  • If the ACM are in good condition leave them in place

  • If the ACMs are in poor condition or could be disturbed

    • Seal them

    • Encapsulate them

    • Remove them


Developing a management plan40 l.jpg

Developing a Management Plan

Prepare a detailed written plan of how to manage the risk

If the ACM are to be left in place:

  • Regularly monitor their condition

  • Procedures for informing others of their presence

  • Permit to work system


Developing a management plan41 l.jpg

Developing a Management Plan

Prepare a detailed written plan of how to manage the risk

  • If the ACM are in good condition leave them in place

  • If the ACMs are in poor condition or could be disturbed

    • Seal them

    • Encapsulate them

    • Remove them


Developing a management plan42 l.jpg

Developing a Management Plan

Implementing the plan

  • An asbestos register in a form readily accessible to maintenance staff

  • Keep the asbestos register up to date


Asbestos register l.jpg

Asbestos Register

  • Asbestos Condition and Exposure Assessments

  • Materials conditions are scored using HSG 264

  • The risk of exposure is scored using HSG 227

  • The combined score allows comparison of materials and the relative risk.

  • This information forms part of an asbestos register along with photographic evidence and plans of the areas


Slide44 l.jpg

Management Principles

  • Who is at Risk?

  • Plumbers

  • Electricians

  • Sky / Audio Visual Engineers

  • Cable Installation Engineers

  • Direct Maintenance Staff

  • Cleaning Staff

  • Tenants


Slide45 l.jpg

Management Principles

Information, Instruction and Training

  • Letters to Service Providers

  • Asbestos included in Contractors Induction

  • Access to Register

  • Software?

  • Hard Copy?

  • Labelling?

  • Direct Maintenance Staff


Management principles l.jpg

Management Principles

Monitoring the condition of asbestos

  • Asbestos materials are assessed using a standard HSE scoring criteria

  • Removal is not usually the safest option

  • Depends on the risk of exposure and the materials condition.

  • Most ACMs are to be left in place and managed


Responsibilities l.jpg

Responsibilities

Asbestos Condition and Exposure Assessments

  • The condition assessment will be recorded as part of your asbestos survey by the asbestos surveyor

  • The risk of exposure is scored using HSG227. You can ask for this to be completed as part of your survey BUT you must check the information as they are your responsibility

  • The combined score allows comparison of materials and the relative risk

  • This information forms part of an asbestos register along with photographic evidence and plans of the areas


Acm condition l.jpg

Types

ACM Condition

Why?

Sprayed Asbestos / Asbestos Boarding in poor condition

(Score 10 -12)

Relatively high asbestos content in a brittle material

In good condition presents a low hazard but often deteriorates

Asbestos Insulation Boarding / Pipe lagging

(Score 5-9)

Cements / plastics / bitumen

(Score <4)

Cements and plastics don’t easily release the fibres


Acm exposure risk l.jpg

Risk Level

ACM Exposure Risk

Why? (Not Exhaustive)

Relatively high levels of activity / risk of damage / Large group of people potentially exposed

Moderate risk of exposure through planned maintenance perhaps. Material is located under water pipes etc.

In a locked, sealed area. Encapsulated. Restricted Access. Very low risk activities etc. etc. (walking on ACM Floor Tiles for e.g.

  • Asbestos Management Firm recommend appointment of contractors


Contractors tender l.jpg

Contractors Tender

  • Contractor writes method statement

  • Fixed price tender based on specifications

  • Tender based on the nature of building and working arrangements, e.g. hospital

  • The need for night or weekend working

  • Should include a statement of accounts for three years


Selection of contractor l.jpg

Selection of Contractor

  • Interviews with contractor will indicate competence

  • Number of staff deployed, standard of supervision

  • Standard of method statement

  • Attitude of senior management

  • Years of experience

  • Lowest bid not necessarily accepted


Selection of laboratory l.jpg

Selection of Laboratory

  • UKAS Accredited for on site fibre counting

  • Experienced staff for carrying out visual clearance

  • Mature experienced staff if managing the asbestos removal operation

  • Must be appointed directly and not as sub-contractor to the asbestos removal contractor


Asbestos removal l.jpg

Asbestos Removal

  • Working Enclosure

  • Apply negative pressure to the enclosures to prevent air escaping

  • Smoke test


Asbestos removal59 l.jpg

Asbestos Removal

  • Use working methods which reduce the airborne respirable fibre concentrations inside the enclosures

  • Double bag asbestos waste

  • Transit routes

  • Decontamination units


Air monitoring l.jpg

Air Monitoring

  • Monitor operatives inside enclosure

  • Monitor airborne asbestos fibres outside the enclosure

  • If any leak of fibres detected. Stop work
