Industrial Hygiene Testing

Overview of Industrial Hygiene Testing

“Industrial Hygiene is a science and art devoted to the anticipation, recognition, evaluation, prevention, and control of those environmental factors or stresses arising in or from the workplace which may cause sickness, impaired health and wellbeing, or significant discomfort among workers or among citizens of the community.”[1].

MVA Scientific Consultants helps industrial hygienists by using analytical microscopy and spectroscopy to test dust and debris containing unknown particles. Traditional industrial hygiene test methods like extraction/digestion followed by chromatography or elemental analysis do not usually give meaningful results when applied to the analysis of particles. Our lab reports provide qualitative and semi-quantitative information such as composition of materials and general population of the constituents.

Insights from Industrial Hygiene Testing

Some particles are so small that they can pass through the nose’s filtration system and reach the lungs. Microscopy allows us to view objects that cannot be seen with the naked eye. The advantage of using microscopy for debris analysis is that it gives morphological, chemical, and molecular information about the particle in its unaltered state. Particles are found in homes and workplaces and may be harmless, a nuisance, or hazardous. They might be biological, chemical or physical agents that could have a serious effect on people’s health and wellbeing.  It is important to identify those particles to know the potential risk they present. Dust may contain microbes or fungi (mold) that release toxins. It may also contain chemicals such as pesticides or dyes that can cause cancer. Dust or debris may contain particles of material such as asbestos, silica, iron, and coal.

We can identify skin cells, soot, pollen, fungal material, animal hairs, soil minerals, construction debris, fiberglass, clothing fibers, insect parts, rubber and polymer fragments and many other components of dust and debris. Identification of the individual particles present in dust or debris can help the industrial hygienist identify the source and develop a plan to minimize or eliminate exposure to dangerous contaminants.
