Specialized Expertise

Environmental Profiles project manager Leonard Burrelli at job siteAs the industrial workplace becomes more complicated, the demand for health & safety professionals with specialized expertise rises. At Environmental Profiles, some of the "hot-button" areas in which we have experience beyond most industrial hygiene firms include:


Workplace exposure to organic solvents can be a potential threat to health, productivity and efficiency in most industries and occupations. Some of the countless uses of organic solvents include:

These are only a few of the countless workplace products containing organic solvents. Many common products packaged in cans and drums contain mixtures of organic solvents.

Exposures that exceed threshold levels can lead to effects that are potentially harmful to the worker's health and can potentially impair functioning. Some of these effects are irreversible and can lead to permanent damage.

Environmental Profiles provides the resources and experience you need to manage solvent exposures in your workplace. Through onsite analysis and/or mathematical modeling, we will identify the solvents present and prioritize their hazard potential. Our ultimate goal is always a cost-effective means to manage solvent exposures.


The combination of flame, fumes, heat, confined spaces and toxic materials makes welding a singularly hazardous procedure requiring a thorough mastery of the many different elements involved. There are more than 80 different types of welding and associated processes, presenting unique challenges to worker safety. Hazards from welding can arise from:

These hazards can lead to short-term and long-term health effects that range from mild discomfort to death.

Environmental Profiles has vast experience in welding environments and will work with you to develop a program to manage welding hazards by:

Vinyl Chloride

Vinyl chloride is a colorless, flammable gas at normal temperatures and is used throughout the world to produce polyvinyl chloride (PVC). PVC is used to make a variety of plastic products, including pipes, wire and cable coatings, furniture, and automobile upholstery.

Historically, the flammable and anesthetic qualities of vinyl chloride have been well known. However, in 1974 B.F. Goodrich announced to the Occupational Safety and Health Administration (OSHA) through the National Institute for Occupational Safety and Health (NIOSH) that a few deaths of its employees from angiosarcoma of the liver may have been occupationally related. It was this announcement that resulted in significant health and safety investigations, regulatory changes, and an expansion of the vinyl chloride monomer toxicity and epidemiological studies. This research led to worldwide recognition of this occupational health issue, and the application of improved technology and sampling methodologies that significantly reduced workplace exposure to vinyl chloride. Additionally, an emergency temporary standard governing workplace exposure to vinyl chloride was adopted by OSHA in 1974, and a permanent standard was adopted in 1975.

Because the rules and regulations for vinyl chloride use were radically different before the newer guidelines were introduced, investigations into vinyl chloride exposure histories require industrial hygienists who are not only familiar with the specialized exposure assessment processes, but are also well-versed in the vinyl chloride history. Staff members at Environmental Profiles include industrial hygienists with specific expertise in both of these areas.

Silica is found in many common building materials, such as sandstone, granite, flint, and slate. Unless proper controls are in place, when workers breathe in microscopic silica particles released from rocks and ores, the result can be diseases such as silicosis and acute silicosis. Silicosis is a chronic disease that causes difficulty in breathing and increases the risk of other lung diseases, such as tuberculosis, and may lead to heart failure or lung cancer. Acute silicosis develops rapidly when workers breathe in large amounts of very fine crystalline silica and results in severe lung damage or death.

Jobs at special risk for silica exposure include:

Employing OSHA and NIOSH standards and guidelines, Environmental Profiles identifies the likelihood of silica exposure and outlines practices and controls to reduce worker exposure to this common material.
