Generally speaking, asbestos containing materials (ACMs), such as asbestos-cement roofs, do not seem to pose a health risk to occupants, provided they are maintained in good condition and the materials are not disturbed in any way (by processes such as cutting, drilling, high pressure water cleaning, etc). Only if the ACMs are disturbed by such processes in an uncontrolled manner, and fibres get dispersed into the air and inhaled, there might be a significant health risk.
The Asbestos Regulations require that any ACMs in a building are kept in good condition and an inventory is kept on the premises of their location, condition and extent. Any person performing work on these materials must be informed and trained, and take the necessary precautions (such as wearing a respirator mask and wetting the material beforehand) to minimize the risk and protect their health.
See Asbestos Regulation and Information pamphlet below.
The current asbestos legislation requires that any removal of asbestos and asbestos containing materials (ACMs) is carried out by a Department of Labour Registered Asbestos Contractor (RAC) under controlled conditions. Work on ACM can be done by persons other than RAC, provided they follow the work safe procedures as outlined in the Regulations (see particularly section 15).
See Asbestos Regulations, List of RACs and Information Pamphlet below.
For further information on RACs, contact the Department of Labour

- MSDS- Material Safety Data Sheet of what the client is exposed to.
Upon receiving the above, an appointment date will be allocated.M/p>
Asbestos is an inert material and does not have any smell. It is a serious health risk when dry asbestos fibre dust is present in the air. However, if the ceiling does contain asbestos and is deteriorating it should be repaired, sealed and replaced. There is a legal obligation to keep a register of any asbestos materials on site and only DoL Registered Asbestos Contractors are allowed to remove/ replace asbestos containing materials. Any work on asbestos materials must be performed by trained personnel, taking the necessary precautions.
See information pamphlet and Asbestos Regulations below.
Exposure to asbestos has been linked to the development of serious lung diseases, among them cancer and asbestosis (asbestosis is more linked to heavy, occupational exposure). What is common to all asbestos related diseases is a long latency period,
i.e. disease only manifest years after being exposed (typically 15-50 years) following exposure. It is therefore, very unlikely that your children falling ill, is in anyway asbestos related.

It is stated in the Asbestos Regulations:
Cleaning is done under controlled conditions ensuring that
- Dry-brushing, scraping, sanding and abrasion techniques are not used;
- Where reasonably practicable, high-pressure water jetting is not used unless in conjunction with a suitably profiled hood that limits dispersal of contaminated water and, if the said jetting is used, that suitable control methods are used in accordance with regualtion 13(2)(b); and
- When fungicidal solution or moss killer is applied, a standing time of 24 hours or any other period specified by the manufacturer is allowed, and a low-pressure hose is used after such a period to keep the sheets wet whilst employing a stiff broom any similar means to remove any moss or lichens.
With regard to the contamination of water with asbestos
- That any water that is contaminated with asbestos as a result of work being performed is passed through a filtration system before being released into any environment or water system; and
- That a suitable water filtration system is used which will ensure that the asbestos being released or entering into any environment or water system is reduced as far as is reasonably practicable;
- That contaminated parts of the filtration system, when discarded, are disposed of as asbestos waste; and
- That appropriate measures are taken to prevent the release of asbestos dust into the environment arising from the transport of asbests.
At present, the NIOH does not have an accredited method for determining asbestos fibre volume in soil.
Since 2008, it is a legal offence to sell asbestos containing materials.
The NIOH has produced a pamphlet called “Noise in the workplace and ‘Buy-Quiet’ Policy”. See the pamphlet at the bottom of the page.
As specified in the Asbestos Regulations, 2001, working or dismantling of asbestos cement products must be carried out under strict controlled conditions to prevent exposure to asbestos fibres and environmental contamination. These conditions are stipulated particularly in sections 15, 11 and 13 of the Regulations.
