Industrial hygiene has been defined as “that science and art devoted to the anticipation, recognition, evaluation, and control of those environmental factors or stresses arising in or from the workplace, which may cause sickness, impaired health and well-being, or significant discomfort among workers or among the citizens of the community.”

Industrial hygienists use environmental monitoring and analytical methods to detect the extent of worker exposure and employ engineering, work practice controls, and other methods to control potential health hazards such as:


  • Physical Agents such as ionizing and non-ionizing electromagnetic radiation, noise, vibration, illumination, and temperature.
  • Air Contaminants such as dusts, fumes, mists, aerosols, and fibres.
  • Chemical Hazards such as neurotoxins, immune agents, dermatologic agents, carcinogens, reproductive toxins, systemic toxins, asthmagens, pneumoconiotic agents, and sensitizers.
  • Biological Hazards such as bacteria, viruses, fungi, and other living organisms
  • Ergonomic Hazards such as repetitive movement, manual handling, workplace/job/task design, uncomfortable workstation height and poor body positioning.


In sum, industrial hygiene encompasses a broad spectrum of the working environment. Early in its history, OSHA recognized industrial hygiene as an integral part of a healthy work setting. OSHA places a high priority on using industrial hygiene concepts in its health standards and as a tool for effective enforcement of job safety and health regulations. By recognizing and applying the principles of industrial hygiene to the work environment, North America’s workplaces will become more healthful and safer.


Examples of Workplace Exposure Assessments Conducted by Sonic Hygiene Include:

  • Spray Paint Operations (various volatile organic compounds and isocyanates)
  • Non Destructive Testing Processes (radiation, volatile organic compounds, noise, dust)
  • Factories and Industrial Plants (noise, vibrations, Silica and dusts, ergonomics, carbon monoxide)
  • Anodising Operations (fluorides, sulphuric acid)
  • Paint Manufacturing Facilities (lead, fluorides, nitric acid)
  • Stone and Concrete Works (silica and other airborne particulate)
  • Woodworking Facilities and Mills (wood dust, methyl methacrylate, butyl acrylate, mold)
  • Salons and Hairdressing Facilities (ammonia, formaldehyde, volatile organic compounds)
  • Operating and Recovery Rooms (anesthetic gases including nitrous oxide, sevoflurane, desflurane and isoflurane)
  • Histology Labs, Autopsy Suites and Anatomy Laboratories  (formaldehyde, ethanol, toluene)
  • Transit and Trucking Facilities (nitrogen oxides, sulphur dioxide, ozone, carbon monoxide, formaldehyde, volatile organic compounds, particulate)
  • Law Enforcement (noise, lead, vibration)
  • Fire Fighters (poly aromatic hydrocarbons, noise, lead)
  • Oil and Gas Production (noise, benzene, toluene, ethylbenzene and xylene, H2S, ergonomics)
  • Electronic Recycling (noise, lead, mercury, cadmium, dust)
  • Smoothie Bars (Noise)
Did you know?

Noise-induced hearing loss (NIHL) is the second common OD. Since 1991, annually 200-300 cases of NIHL are compensated, including sudden hearing loss. Hand-arm vibration syndromes (HAVS) have been reported in workers using grinders that produced hand-transmitted vibrations. Approximately, 15 cases of HAVS are compensated in a year. Heat related diseases such as heat stroke were also reported. Diseases caused by compressed and decompressed air have been continuously reported. Radiation-related diseases such as leukemia were reported recently; these cases of radiation exposures were attributed to the use of non-destructive examinations.
