WHAT IS ASBESTOS Asbestos is the name applied to six naturally occurring

minerals that are mined from the earth. The different types of asbestos include:

Chrysotile – Canada (brown asbestos)

Amosite – South Africa (white asbestos)

Crocidolite – Africa and Australia (blue asbestos)

Actinolite – USA (Libby Montana-Vermiculite Insulation)

Tremolite – (Occasionally found with talcum powders)

Anthophyllite – (Occasionally found in certain vermiculites)


TYPES OF ASBESTOS There are Two Main Types of Asbestos Found in Building Materials

Serpentine Asbestos

- Chrysotile

- Defined as a wavy fibre

- Accounts for 90% of the asbestos used in building materials in

Canada

Amphibole Asbestos (in order of commercial use)

- Amosite, Crocidolite, Actinolite, Tremolite and Anthophyllite

- Defined as a Hard Strait Fiber

- More likely to cause disease due to the make up of the fibre


Raw Chrysotile Fiber Block


Actinolite Asbestos Under 400X Magnification


WHAT ARE THE

ADVANTAGEOUS QUALITIES OF ASBESTOS?

Chemical resistance (will not corrode)

Thermal resistance (will not burn)

Tensile strength (proportionally as strong as steel)

Ability to be woven or incorporated into other

products


WHERE IS ASBESTOS USED

Asbestos was known as the product with a thousand uses, but today has been used in over 3000 manufactured products; typical uses include:

Insulation (heat resistance and thermal insulating qualities)

Vinyl flooring (tensile strength)

Gasketing (heat resistance and tensile strength)

Textiles (heat resistance and tensile strength)

Cement board and piping (tensile strength and chemical resistance)

Auto brake shoes (heat resistance and tensile strength)

Roofing felts (tensile strength, chemical and decay resistance)

Asphalt (tensile strength)

ASBSTOS RELATED DISEASE

ASBESTOSIS

Asbestosis is the name given to

scarring and stiffening of the lungs

caused by inhaling asbestos dust over

many years. It makes breathing difficult.

It can lead to fatal complications such

as pneumonia, heart disease, and lung

cancer



LUNG CANCER

Hypotopic cell growth creating tumors

Smoking increases your risk of

lung cancer by 10%

Working with asbestos increases

your risk of lung cancer by 10%

Smoking and working with asbestos

increases your risk of lung cancer

by 100%


ASBSTOS RELATED DISEASE MESOTHELIOMA - A rare cancer of the linings of the lungs and

abdomen that almost always leads to death.

- Practically all mesothelioma cases are linked to asbestos exposure. These diseases usually develop decades – 25 to 40 years – after the worker was exposed to asbestos fibres.

- Workers who develop asbestosis or mesothelioma have usually been exposed to asbestos fibres during processes such as installing, removing, or simply working around asbestos insulation or other asbestos-containing materials.


The bottom lines shows the period when asbestos-

containing materials were heavily used with little or no

controls or worker protection. The next line shows when

claims for asbestos-related diseases were accepted by the

WCB; the number of claims is expected to have peaked

and to have begun tapering off by 2010. The top two lines

show the period of deaths from the earlier asbestos

exposure, projected into the future. Workers with

asbestosis generally survive longer than workers with

mesothelioma.



WHAT REGULATIONS ARE IN PLACE REGARDING ASBESTOS?

WorkSafeBC (WCB) Occupational Health and Safety Regulation

- Establishes worker exposure limits for protected and unprotected persons

- Details worker training and work area preparation for removal

- Limits its use

Health and Welfare Canada

- Federally Regulated Sties (CP, CN, Canada Post)

Ministry of Water Air and Land Protection - Hazardous waste generator requirements

- Disposal requirements

Department of Transportation - Transportation of Dangerous Good Regulation

WSBC ACCPETED 2006 WORK RELATED DISEASE DEATHS DUE TO ASBESTOS

Cause of Death : Asbestos exposure

CARPENTER - died as a result of exposure to asbestos while working as a carpenter in smelters for more than 20 years.

LONGSHORMAN - died as a result of long-term exposure to asbestos while loading and unloading it onto ships.

CABINET MAKER/INSTALLER - died of mesothelioma after decades of exposure to asbestos in insulation.

GRAPPLE YARDER OPERATOR - died as a result of decades of exposure to asbestos while changing brake pads on logging machinery.

PIPE LAYER – died as a result of being exposed to asbestos for years while cutting, drilling, fitting, and laying concrete asbestos pipe.

WELDER - died of asbestos-related illness after being exposed to asbestos over a long period of time while working as a welder.

POWER CUTTER OPERATOR - died after more than 30 years of exposure to asbestos while operating a power cutter in the printing industry.

MILL WORKER - died as a result of long-term exposure to asbestos while working in aluminum smelters and pulp mills.

TILE SETTER - died as a result of exposure to asbestos filler while mixing acrylic powders with dry cement.

VEHICLE INSPECTOR - died as a result of being exposed to crocidolite asbestos in the building where the inspections took place.

TRUCK DRIVER - died after being repeatedly exposed to asbestos while repairing and adjusting his brakes.

BOILERMAKER - died of mesothelioma from exposure to asbestos while working with boilers.

PAINTER - died of mesothelioma after decades of exposure to asbestos while working as a painter in steel frame erection.

TREATMENT PLANT OPERATOR - died of disease caused by years of exposure to asbestos while working in a phosphate plant.

MECHANIC - died of asbestos-related disease after being exposed to asbestos while working in mines as a mechanic and heavy equipment operator.

INSULATION PLANT WORKER - died of asbestos-related disease. He had worked in the manufacture of a type of vermiculite insulation that contained asbestos.

PLASTER - died of asbestos-related disease. He had been exposed to asbestos while working as a plasterer in the 1950s, when asbestos was added to plaster to make it stronger and fire-resistant.

CHARTERED ACCOUNTANT - died of asbestos-related disease had been exposed to asbestos while working for a metal product manufacturer in the 1960s and 1970s.

PHYSICAL PLANT ENGINEER - died of mesothelioma caused by exposure to asbestos while working around boilers and steam works.


Work-related diseases present special challenges because workers may

not be aware they have a health problem until many years after their

exposure. For example, workers exposed to asbestos may wait as long as

25 to 40 years before they receive a diagnosis of asbestosis or

mesothelioma.

Asbestosis is often a slowly progressive disease, meaning that most of the

workers who died of asbestosis in 2001 had their claims accepted by the

WCB 15 to 25 years earlier. Mesothelioma is a relatively rapid progressive

disease, meaning that most of those who died of of mesothelioma in 2001

had their claims accepted 6 months to 2 years earlier.

As workers reach the end of the 25 to 40 year period after exposure to

asbestos, more and more workers are being diagnosed with this disease.

For example, the WCB accepted 41 mesothelioma claims for long-term

disability in 2001 compared with 5 claims in 1990.

TIME FRAME FOR WORK-RELATED DISEASES


Two of the most important things school districts can do are to maintain an

accurate inventory of asbestos-containing materials in their buildings, and to

keep that inventory up-to-date. This information must be reviewed carefully

and communicated to workers before any demolition or renovation work takes

place.

HOW CAN SCHOOL DISTRICTS REDUCE THE

RISK OF WORKER EXPOSURE TO ASBESTOS?


Two of the most important things school districts can do are to maintain an accurate inventory of asbestos-

containing materials in their buildings, and to keep that inventory up-to-date. This information must be

reviewed carefully and communicated to workers before any demolition or renovation work takes place.



Any gaps in the asbestos inventory should be filled by sampling (or re-

sampling) suspected building products. This is particularly important for

gypsum board filler as well as concealed linoleum and vinyl tile flooring,

because classrooms may contain a mixture of asbestos-containing wall,

ceiling, and flooring materials both exposed and concealed beneath covering

carpeting and non-asbestos flooring materials.

products. This is particularly important for gypsum board filler as well as concealed linoleum and vinyl tile

flooring, because classrooms may contain a mixture of asbestos-containing wall, ceiling, and flooring

materials both exposed and concealed beneath covering carpeting and non-asbestos flooring materials.

Loose-fill vermiculite insulation can be present in attics and concrete block

walls. This material may contain between 0.3 and seven percent asbestos.

Asbestos is an ALARA (as low as reasonably achievable) substance, and

workers must be made aware of its presence even in small amounts (i.e., less

than one percent).

It is very important to make sure that the person who conducts the

assessment and sampling is qualified and trained, and that the samples are

sent to a qualified asbestos laboratory for analysis.

ASBESTOS-CONTAINING MATERIALS LOCATED WITHIN

RUTLAND MIDDLE SCHOOL The following asbestos-containing materials have been identified within the above noted building:

Asbestos insulating cement on hot water heating pipe fittings in limited areas within the building

Vinyl floor tile and sheeting applications located in various areas throughout the building

Asbestos-containing block fill material is present in perimeter concrete block walls The risk of exposure to airborne asbestos is related to the condition of the asbestos application and its friability. Friable asbestos-containing materials, such as insulating cements, mechanical insulation and asbestos paper products pose the greatest risk of exposure to building occupants as they are easily crumbled by hand releasing airborne asbestos fibres when damaged or exposed. Non-friable materials, such as vinyl flooring, cement asbestos board and drywall filler applications pose a lesser risk as they are not easily crumbled by hand and must be broken or mechanically abraded to release asbestos fibres.

Friable asbestos applications have been identified within this building as insulating cement on hot water heating pipe fittings in four (4) areas of the building. As access to theses asbestos application is limited and controlled, the applications are in good condition and enclosed beneath a layer of canvass and glue, there is currently no building occupant risk of exposure to airborne asbestos from this application.

Non-friable asbestos applications have been identified within this building as vinyl flooring applications. As these applications are non-friable and in good condition, mechanical abrasion would be required to create the release of the asbestos fibres which are bound into the matrix of the material. There is currently no building occupant risk of exposure to airborne asbestos from this application.
