Resumen |
This report examines the effectiveness of the bag control method during the removal of asbestos-containing pipe lagging and evaluates different sampling and analysis methods for determining the level of asbestos contamination. Glossary. During asbestos removal operations in 4 public schools, personal exposures to airborne fibres were determined using phase contrast microscopy (PCM) methods. Aggressive and non-aggressive sampling techniques were used for collecting area samples and sample analysis was performed using both PCM and transmission electron microscopy (TEM). Results indicated that the glove bags did not completely contain the asbestos and that the choice of sampling and analysis methods could have an effect on the perceived level of asbestos contamination.
