Industrial hygiene is a term designed to evoke a simple view of what the practice means. However, it comes from a time when the words had a different interpretation to them. Industrial seems clear enough – practicing in a work or factory setting, but even that gets blurred these days when defining a problem in an office setting. Hygiene comes from the area of practice relating to cleanliness, sanitation, or health. Therefore, as initially determined, an Industrial Hygienist (IH) is a professional who is dedicated to the health and well-being of the worker.
An Organizational Chart to Guide Sample Preparation for Polarized Light Microscopy (PLM) Analysis of Bulk Samples for Asbestos
In the U.S.A., there are many organizations such as the Occupational Safety & Health Administration (OSHA), the Department of Energy (DOE), the National Fire Protection Association (NFPA) and MSHA (Mine Safety & Health Administration) that require or recommend the use of non-sparking hand tools in many industrial applications.
The following Rules are established by the Board of Directors of the National Fire Protection Association for the certification and/or recertification of Marine Chemists.

A New Application of the PCM Method Used for Asbestos in Air Samples to Prepare Reference Slides for Mold Spores
The following list does not include every product/material that may contain asbestos. It is intended as a general guide to show which types of materials may contain asbestos.
Ion-exchange resins are synthetic polymers capable of combining or exchanging ions in a surrounding solution and are used primarily for deionizing water or for chromatography of organic molecules.
A Marine Chemist is the holder of a valid Certificate issued by the Board of the National Fire Protection Association in accordance with the “Rules for the Certification and Recertification of Marine Chemists” establishing the holder as a person qualified to determine whether construction, alteration, repair, lay-up, or shipbreaking of vessels, which may involve hazards covered by the Standard, can be undertaken with safety.
Asbestos is the name given to a number of naturally occurring fibrous silicate minerals that have been mined for their useful properties such as thermal insulation, chemical and thermal stability, and high tensile strength. The three most common types of asbestos are: a) chrysotile, b) amosite and c) crocidolite. Chrysotile, also known as white asbestos and a member of the Serpentine mineral group is the commonest. Asbestos can only be identified under a microscope.
Lead is a highly toxic metal that was used for many years in products found in and around our homes. Lead may cause a range of health effects, from behavioral problems and learning disabilities, to seizures and death. Children 6 years old and under are most at risk, because their bodies are growing quickly.
Molds produce tiny spores to reproduce. Mold spores waft through the indoor and outdoor air continually. When mold spores land on a damp spot indoors, they may begin growing and digesting whatever they are growing on in order to survive. There are molds that can grow on wood, paper, carpet, and foods. When excessive moisture or water accumulates indoors, mold growth will often occur, particularly if the moisture problem remains undiscovered or un-addressed. There is no practical way to eliminate all mold and mold spores in the indoor environment; the way to control indoor mold growth is to control moisture.
Noise, or unwanted sound, is one of the most pervasive occupational health problems. It is a by-product of many industrial processes. Sound consists of pressure changes in a medium (usually air), caused by vibration or turbulence. These pressure changes produce waves emanating away from the turbulent or vibrating source. Exposure to high levels of noise causes hearing loss and may cause other harmful health effects as well. The extent of damage depends primarily on the intensity of the noise and the duration of the exposure.
