industrial hygiene
Industrial Hygiene is the science of protecting the health and safety of people in the workplace and the community. It includes anticipating, evaluating and controlling exposures to dusts, chemicals, biohazards, noise, and physical hazards. W.M. Ewing & Company personnel routinely conduct audits of the workplace to determine possible occupational health hazards, compliance with applicable state and federal regulations and chemical inventory. Detailed surveys are performed to evaluate employee exposures and work practices, the performance of local exhaust ventilation and the use of personal protective equipment. We conduct investigations in a variety of operations including hospitals, schools, poultry plants, foundries, battery plants, aircraft maintenance facilities, chemical manufacturing, laboratories, power generation plants, and office buildings.
indoor environmental quality
Indoor Environmental Quality (IEQ) refers to the quality of a building’s environment in relation to the health and wellbeing of those who occupy space within it. Indoor environments are highly complex and building occupants may be exposed to a variety of contaminants (in the form of gases and particles) from office machines, cleaning products, construction activities, carpets and furnishings, perfumes, cigarette smoke, water-damaged building materials, microbial growth (fungal, mold, and bacterial), insects, and outdoor pollutants. Other factors such as indoor temperatures, relative humidity, and ventilation levels can also affect how individuals respond to the indoor environment. Understanding the sources of indoor environmental contaminants and controlling them can often help prevent or resolve building-related worker symptoms.
