Fee: SGD$1710.93 (including GST)

Delivery: Virtual Instructor-led Training (using Zoom)

Asbestos has been used for decades as an inexpensive industrial material with properties such as high tensile strength, heat resistance, incombustibility and resistance to chemical attack. It has been known for more than 50 years that exposure to asbestos can cause serious diseases including cancer and asbestosis.

Use of asbestos is now banned in most countries but it is still produced and used in some countries in Asia. However, even where use is restricted, asbestos can still be present in buildings, industrial plants and ships. Those considered most at risk now are workers who may disturb asbestos materials during repair, maintenance and refurbishment work.

This course covers the composition, nature and properties of asbestos, man-made mineral and other fibres, their historical uses and their health effects.

It will cover the principles of and requirements for asbestos surveys based on relevant safety requirements and current good practice in construction, and use of enclosures for asbestos remediation.

Conducting air sampling to determine airborne concentrations and advice on techniques for the management of asbestos in buildings will also be covered.

This course enhances the knowledge of occupational hygiene practice in relation to fibrous dusts. The module concentrates on asbestos, but other fibres, e.g., machine made mineral fibres, aramids, carbon, etc., which are increasingly finding uses in industry are covered.

Successful completion of this module will benefit those working in asbestos consultancy as well as in mainstream occupational hygiene, giving an understanding of the health risks associated with asbestos and other fibres as well as the means for evaluation and control.

Who should attend?
Workplace safety and health professionals, air quality monitoring professionals, hygienists and those in similar professions.
