Do old boilers have asbestos insulation?
Older boilers are at risk of having some sort of asbestos boiler insulation fitted.

It was a way of helping to keep energy costs low and to prevent the risk of fire.
What does asbestos in a boiler look like?
On the internal pipework, the asbestos boiler insulation looks similar to corrugated cardboard and is made up of between 75 and 90 percent chrysotile asbestos. Other components that contained asbestos were portals and pipes (asbestos gaskets were used) and rope seals on the stove doors. Is a boiler with asbestos dangerous?

Do all houses built in 1960 have asbestos?
The vast majority of homes older than 15 years--especially those built in the 1950s and 1960s--contain a number of asbestos products that were used because the substance strongly resists heat, fire and decay. Left undisturbed, the material poses no health threat.
When was asbestos banned from boilers?
Asbestos was commonly used in boilers until it was banned from use in boiler manufacture in 1984. Several pre-1984 boiler models are long-lived enough for examples still to be in use. The problem with these boilers is friable asbestos seals (on combustion chamber covers for example).
Do boiler seals look like asbestos?
Here is a short list of boilers that I know from experience contain seals that look to me like asbestos, and I prefer not to disturb these seals due to the asbestos health risk. These models are all at least 25 years old and I'm inclined to advise replacement if you own one because keeping it maintained is likely to be ever more difficult as fewer and fewer gas technicians are willing to work on them
Can you wet asbestos seals before or after disturbing them?
If an asbestos seal needs to be disturbed, my preference is to wet it with WD40 before and after disturbing it. This seems to lock the fibres down and greatly reduce the risk of them from becoming airborne.
Is a pre-1984 boiler still in use?
Several pre-1984 boiler models are long-lived enough for examples still to be in use. The problem with these boilers is friable asbestos seals (on combustion chamber covers for example). These seals are fragile and disintegrate when disturbed, shedding asbestos fibres into the atmosphere, presenting in my opinion a serious health risk to any technician working on that boiler.
Why is asbestos used in boilers?
Asbestos was also used around boilers because it is fireproof, non corrosive and it doesn’t conduct electricity.
How much does it cost to remove asbestos boilers?

Pre 1984, when the UK banned the use of asbestos in boiler manufacture, boilers were the cause of asbestos contamination in many of our buildings. These buildings would include factories, schools, homes, power plants, industrial and military premises.
Can asbestos cause lung cancer?
If these asbestos fibers are inhaled, they can cause serious medical problems and lead to an asbestos related disease such as mesothelioma or asbestos lung cancer. Therefore, anyone attempting to remove asbestos boiler insulation such as pipe lagging is putting themselves at huge risk of asbestos exposure.
How Were Boilermakers Exposed to Asbestos?
Asbestos exposure hazards are present for both types of workers through cleaning, adjusting or repairing the equipment.
Where is asbestos found in boilers?
Asbestos in boilers exists at industrial worksites, such as refineries, factories or power plants, and those in schools, ships and military installations. These locations are also likely sources of asbestos exposure for HVAC mechanics, industrial machinery workers and power plant workers.

What is asbestos insulation?
Asbestos insulation included a mix of asbestos with magnesium carbonate and calcium silicate, and asbestos fibers often made up 6% to 15% of the insulation’s net weight. Popular brands of insulation such as Air-Cell and Air-O-Cell contained between 75% and 90% chrysotile asbestos.
Which occupation is most likely to be exposed to asbestos?
Boiler workers and boilermakers are two occupations most frequently exposed to asbestos and carry the highest risks for asbestos-related disease. The danger comes from regular operation and attendance of the machinery.
Why do older boilers have asbestos insulation?
