Respiratory Protection for Asbestos Dust Sampling

According to the Environmental Protection Agency (EPA), Asbestos is “the name given to a number of naturally occurring fibrous minerals with high tensile strength, the ability to be woven, and resistance to heat and most chemicals.” [1] Because of these characteristics, it has been used in a variety of building materials including dry wall, roofing shingles, cement pipe and sheeting, floor and roofing felts, ceiling and floor tiles, coatings, packing materials, and various other manufactured goods like brake and transmission parts in automobiles.

Over the course of the last century, the ill health effects related to the inhalation of asbestos dust have been proved over and over again. According to the Agency for Toxic Substances & Disease Registry, “significant exposure to any type of asbestos will increase the risk of lung cancer, Mesothelioma and nonmalignant lung and pleural disorders, including asbestosis, pleural plaques, pleural thickening, and pleural effusions.” [2] Symptoms for these diseases may take decades to surface, so preventative safety engineering controls are exceptionally important.

If you believe that your home, building, or workplace may have asbestos-containing materials, the EPA suggests that it is best to consider hiring a professional asbestos inspector to perform an analysis. These inspectors can perform one of several sampling methods to determine if asbestos is present. If you do have an asbestos problem, you should consult the services of an asbestos abatement company.

Sentry Air Systems offers a variety of air purification units to increase respiratory safety protection for asbestos inspectors during their analysis of sample dust or material. These units are designed to help protect the inspector’s respiratory zone by creating an environment that utilizes negative air pressure and a high-quality HEPA filter. Our most popular unit among inspectors is our Ductless Fume Hood, which comes in a variety of sizes:

Sentry Air’s Ductless Fume Hoods utilize a powerful fan and filtration system that pulls harmful particles away from the operator’s breathing zone and into the HEPA filter [up to 99.97% efficient on particles .3 microns and larger]. Ductless Fume Hoods are also available in 30″, 40″, 50″ and custom sizes.

The Winged Sentry (pictured below) operates in a similiar manner by utilizing negative air pressure and HEPA filtration. The sides of the hood are infinitely adjustable, which make for a more customizable workspace for the operator.
