Industrial Hygiene Services

What is Industrial Hygiene?

Occupational exposures to chemical, physical, biological, and ergonomic health hazards occur in industrial, construction, marine, and agricultural work environments. To determine whether these exposures present an employee health risk requires specialized knowledge in the field of industrial hygiene.

Industrial hygiene is the science of preventing illness associated with workplace activities or conditions. The practice of industrial hygiene is devoted to the anticipation, recognition, evaluation, prevention, and control of workplace health hazards.

Health Hazard Assessments

One way to protect employees from experiencing work-related illness is to perform proactive health hazard assessments. CSERT assists its clients by providing this service. These assessments are focused facility inspections and procedural reviews in order to determine the extent of potential employee exposures to hazardous chemicals and conditions.

The service begins with a phone consultation with the employer to obtain background information on the workplace and work conditions. Once the initial consultation is completed, the next step is a site visit conducted by a CSERT Industrial Hygienist. Depending upon the specific workplace, a variety of inspection and review methods are used.

The assessment may include:

  • visual inspection of the work area(s),
  • air monitoring or noise sampling,
  • management and employee interviews, as well as a
  • review of procedures and products used in the workplace.

After the initial assessment is completed, a discussion is held with the employer addressing identified or potential workplace hazards. Recommendations and a written report are provided with the aim of improving workplace safety and health.

These hazard assessments can benefit an employer by:

  • preventing employee illness and injury,
  • reducing liability related to employee illness and injury,
  • reducing downtime and increasing productivity,
  • improving employee morale, and the overall work environment.

If a workplace illness has occurred that is believed to be job-related, CSERT can evaluate the circumstances and provide recommendations to help prevent reoccurrence of such incidents.

CSERT Industrial Hygiene services include:


  • Providing advice on the toxicity of materials and on the substitution of less toxic substances.
  • Evaluating potential health hazards by analysis of air and bulk samples.
  • Recommending ventilation systems and other exposure control measures.
  • Measuring employee exposure to noise and heat with recommendations for controls.
  • Delivering employee training on occupational health issues and job-related health risks.
  • Developing safe work procedures and spill clean–up methods for hazardous materials.
  • Performing employee respirator fit testing.
  • Supplying safety and industrial hygiene services during oil spills.
  • Conducting air monitoring for carbon monoxide, hydrogen sulfide, explosive gases, volatile organic compounds, metals, solvents, silica, and noise, and establishing site recommendations in order to control employee exposures.

Examples of successful projects include:


  • Originating a comprehensive health and safety program for a municipal employer.
  • Developing hexavalent chromium and hazard communication programs for clients.
  • Performing air monitoring studies for silica dust exposure, which resulted in recommendations for an employee occupational health monitoring program.
  • Designing a study which successfully applied local exhaust ventilation to remove hydrogen sulfide gas from the breathing zones of employees during marine cargo tank oil loading operations.
  • Conducting a multi–location noise frequency analysis of a commercial trucking facility, surrounded by residences, resulting in engineering and administrative control recommendations to reduce community noise exposure.
  • Controlling employee noise exposure by retrofitting industrial pumping equipment, resulting in reducing noise levels from deafening to inaudible.
  • Training employees to perform air monitoring in confined spaces.
  • Collecting air samples in order to evaluate potential employee exposures following crude oil spills.
  • Briefing employees on site safety plan contents and evaluating remediation activities to ensure a safe approach to the work.
  • Delivering occupational safety and health procedures and Job Safety Analyses (JSAs) for laboratory and field operations.
  • Supplying safety and health oversight during marine barge confined space cleaning operations.
  • Supplying corrective action recommendations to organizations engaged in oil spill cleanup.
  • Providing respirator fit testing services for employees engaged in chemical and paint manufacturing, industrial plant maintenance, public works, wastewater treatment, ship breaking, animal laboratory, and hazardous waste site clean-up.
  • Working with management to optimize a method of waste disposal handling in order to reduce potential body strains.
