Airborne Asbestos Samples

A certified Indoor Environmental Consultant can be retained for monitoring the air quality for fibre concentration in and around work areas during asbestos abatement. This is a critical step in ensuring your workers’ safety. Airborne samples are taken for “occupational”, and "perimeter/adjacent"areas as per the Alberta Asbestos Abatement Manual (2011). Occupational samples are normally taken from a small personal hygiene pump worn by the worker while they are performing the asbestos abatement. Ambient samples are taken from a larger stationary, high-volume air pump normally placed on the floor of the work space with a stand to elevate the sample.  The same type of laboratory analysis can be applied to both types of samples.

Phase Contrast Microscopy (PCM) is widely used to measure fibre concentrations of air samples. Air sampling is conducted for environmental monitoring, personnel monitoring, and clearance testing for abatement projects. It is used to show your compliance with The Alberta Workplace Health and Safety Code (2009) and other regulatory agencies.

The PCM technique has the advantage of fast turnaround time and low cost. Although PCM is the most widely used technique, it cannot distinguish asbestos fibres from other fibres (ex: gypsum, mineral wool, fibreglass, cellulose etc.). PCM provides an index of the total airborne fibres present in a given size range.

Polarized Light Microscopy (PLM) is used to distinguish actual asbestos containing material concentrations and individual types of fibres. This service will be provided by Jake's Health Consulting Ltd. soon.
