Polarized Light Microscopy (PLM)- Bulk Sampling


Polarized light microscopy (PLM) analysis is the most commonly accepted technique for analysing bulk samples for asbestos. Bulk material samples are typically collected during an asbestos survey by an EPA accredited inspector.The PLM analysis is based on optical mineralogy and uses a phase contrast microscope equipped with polarizing filters. Identification of asbestos is based on

Asbestos Risk Assessment


Exposure Assessment The risk due to asbestosis arises from the inhalation of fibres. A visual assessment of the workplace is the first important step. If a workplace looks dusty, no control procedures are in place and no respiratory protection is being used, workers could have excessive exposure to fibres. Correct fibre identification and fibre counting

Asbestos Sheetrock


More times than not the asbestos tests come back with the drywall mud and/or texture containing asbestos. With early 60’s drywall asbestos could be a problem also. It doesn’t cost much for a test to know what you’re dealing with. Contact Arizona Environmental Specialists at 480-553-7052 to have a qualified inspector discuss your concerns. Abatement
