The condition of asbestos is a major factor for its waste:
Depending on your condition, we can divide asbestos into two large groups.
- Disintegrable – the one that can collapse with the pressure of the hand.
- Not disintegrable – the one that will not crumble under the pressure of the hand, like asbestos sheets in good condition.
If asbestos is in a non-disintegrating condition, we can leave it that way. You can increase safety by painting the surface and the shafts with a sealant that will not allow the fibres to escape. Smoothing the edges or surface will release dangerous fibers into the air. Disintegrating asbestos poses a significant risk because it may crack during handling and may require special care. You should seek the right advice to eliminate asbestos before it becomes a problem.
General tips for asbestos removal:
If you do not know if your appliances have asbestos, it is advisable to contact the manufacturer directly and ask them. Giving the type and year of manufacture can help to find the exact product. Get advice from a specialist on asbestos removal if your appliances contain it. You can use the yellow pages to find companies and people who offer asbestos removal services.
Disposing small amounts of asbestos throughout the house can be done personally, but if the amounts are large, then you should consult with the professional removal agents. They will abide by all laws and dispose of asbestos only at authorised sites.
The solution to the removal process is to make sure that the fibres do not separate and fly in the air. To this end, experts advise that the removalist takes care of asbestos on a damp, calm day and reduce the number of people involved in the process to a minimum. Any disassembly of structures will provide opportunities for fibres to separate and fly. When dismantling, keep the asbestos sheet wet with soap and water to make less dust and fibres.
After removing the asbestos, you should pack it in heavy plastic sheets. Smaller pieces can be stored in double polyethene bags. Any remaining dust can be collected using a wet cloth and stored in double plastic bags. You should get rid of the clothes you wear for this process in the same way.
As said above, whenever the removalist observes the precautions of common sense according to the advice for the elimination of the asbestos, and he makes sure that the fibres do not contaminate the outside and the quantities are small, there is no danger. However, it is essential that you’d be aware of the “clean air act” and similar laws before disposing of large amounts of asbestos.
Asbestos Roof Tiles – Potential Hazards and Precautions
Asbestos was widely used as a component of the ceiling coated in splashes in houses or as roof tiles. It was also used as a decorative spray on walls or for soundproofing purposes. However, there has been a lot of concern lately about the use of asbestos tiles for the roof because of the harmful effects that asbestos particles have on human health.
Hazards from Asbestos Roof Tiles
Asbestos contains silicate fibres that can be released into the air by applying physical force to the tiles. Being inhaled, these fibres are retained by the lungs and cause lung disorders, such as mesothelioma or asbestosis. Even if ceilings do not have asbestos, certain insulation materials such as Zonolite, which is used on attic floors, can release toxic levels of asbestos while fixing a ceiling fan or light. Asbestos tiles may contain formaldehyde and other volatile organic components. The asbestos in the tiles, if in good condition, does not cause any risk, but if it is released, moist or crumbles, it is dangerous. Piercing and scraping of this material is a health hazard. In these cases, building owners should remove asbestos tiles from the roof or take steps to avoid exposure to asbestos.
Safe Handling of Asbestos Roof Tiles
The best way is to avoid using asbestos tiles. However, if you are using such tiles, you should take the necessary precautions to avoid exposure to asbestos.
Some steps to follow are:
- Select low emission shingles that are certified by a reputed organization.
- Use porous tiles that trap odours and released chemicals released by construction activities.
- Install roof tiles in a building only after having painted, laid the floor, or finished any other type of work. This step prevents roof tiles from absorbing and retaining organic chemicals and solvents.
- Recycle the old tiles.
- Hire professionals to rebuild asbestos shingles that adhere to safety standards and rules. Avoid sanding and polishing asbestos floors.
- Use an aqueous thinner to soften the paint or varnish or use low abrasion sanders, less than 300 rpm to avoid exposure.
- Report any broken tiles to the Department of Environmental Health and Safety.
- Submit an employee exposure report within 24 hours or as soon as possible to the Department of Environmental Health and Safety in the event of accidental exposure to asbestos.
Remember! Minimal exposure to asbestos fibres can cause lung disease, asbestosis or mesothelioma. Therefore, it’s always better to be safe than sorry.
