Asbestos Awareness Course Revision Notes
What Is Asbestos ?
Asbestos is a name given to over 30 different types of materials all based around the compound magnesium silicate. Mixed with other metals which have crystallized due to volcanic action.
There are two types of asbestos which has been used in the construction industry from bricks and roofs to ceiling and floor tiles. Asbestos was also used in the automotive industry in the manufacture of brake components.
- Amphiboles, referred to as blue, brown and tremolite asbestos.
- Serpentine referred to as white asbestos (chrysotile).
Note: The practice test questions for the UKATA mock exam further down the page.
Until its ban in the UK in 1985, asbestos was mainly used to manufacture textured finishing, thermal insulation, insulating boards, rope, cement sheets, pipes and many different car parts.
Asbestos was mined in the USA, USSR, Canada, South Africa and Australia as well as many other countries. It is still used today in third world countries unchecked and unregulated.
Effects of Exposure to Asbestos Dust.
The fibres are so tiny that they can hang around in the air in an undisturbed room for days. Inhaling these fibres is lethal.
It is inhaled into the lungs and cannot be removed by the bodies natural defences. The long term effects may not even be noticed for over 15 years, by which it is already to late for the person.
Some of the effects/diseases caused by asbestos are commonly known as Mesothelioma, Asbestosis, Lung Cancer, Plueral plaque, and Laryngeal Cancer.
Identification of Asbestos
The 2006 CAR ( Control of Asbestos Regulation ) requires that any contractor is required to identify any and all materials in the building prior to any work commencing.
They Can Do This by the Following Methods:
- Use of information from the material supplier
- Analysis of the material
- Reference to building plans to identify possible asbestosis types.
Death From Asbestosis
The government announced that in 2011, there were 178 deaths recorded as a direct result from asbestosis, with another 301 deaths possibly caused by inhalation of this deadly dust.
In 1978 there were only 109 deaths, that figure appears to be increasing as the affects are now taking hold of construction workers.
In 2012, that number rose to over 1000, by 2015 it was 1200.
Thousands of cases of asbestosis go unreported as the diagnosis is perceived wrongly. These figures are for the UK only.
It is estimated that over 3 million people across the USA have asbestosis, but as yet, they do not know it.
Practice Mock Questions for the UKATA Exam (UK)
The UKATA ( United Kingdom Asbestos Training Association ) certification is now required for many construction and demolition jobs. Asbestos is an agonising silent killer, and globally, is responsible for millions of deaths.
The asbestos awareness course has been introduced in an attempt to help limit the number of asbestosis cases within the UK. The certification is valid for one year, and costs between £20 - £37, depending on whom you go through. The exam can be done in minutes on-line with a printable certificate upon completion.
The compilation below of mock or practice questions may appear in all or some of the UKATA exams. Answers at foot of page.
