Industrial Hygiene

Surface sampling for hexavalent chromium to determine area contamination during an industrial hygiene evaluation

Are you concerned about exposures to employees in an industrial facility? Indoor Science offers a wide range of industrial hygiene services.  Ian Cull is a Certified Industrial Hygienist (CIH) and respected consultant in the Chicagoland area.  We can help you respond to an OSHA violation, or just help you proactively evaluate if worker exposures are within health and safety regulations.  If you are looking for a certified industrial hygienist in Chicago and beyond, give us a call today at (312)920-9393.

Personal Monitoring

Our services include both industrial hygiene personal monitoring and area sampling for chemicals, particles, noise, thermal stress and more.  Personal monitoring is performed when evaluating a worker’s exposure.  Sampling equipment is unobtrusively mounted on the worker and draws air from the breathing zone.  Industrial hygiene monitoring is often performed over an 8 hour period for regulatory compliance.  It is important to compare results to OSHA’s Permissible Exposure Limits (PELs), which are often expressed as an 8-hour time-weighted average.  For some select exposures, OSHA has short-term exposure limits (STELs) and ceiling limits as well.

Area Monitoring

Some projects call for area monitoring, rather than personal monitoring.  Area monitoring collects an air sample or measurement in a fixed location.  Area monitoring might be used during an initial risk assessment to evaluate some of the important exposures that might be happening in the facility.  For example, you may be unsure if workers are exposed to chemicals regulated by OSHA.  Area monitoring can determine the extent of a problem throughout a factory or map out concentrations throughout a manufacturing facility.

Industrial Hygiene Services

We can perform personal or area monitoring for just about anything.  Our partner laboratories have capabilities to analyze thousands of different chemicals and other contaminants.  Here are some of the most common parameters sampled in our occupational hygiene projects:

  • Welding fumes
  • Hexavalent chromium
  • Asbestos
  • Silica
  • Noise
  • Benzene
  • Respirable dust and total dust
  • Formaldehyde
  • Mold, bacteria, sewage
  • Methylene chloride
  • Much more

Finding Solutions

Not only do we collect industrial hygiene air samples, we also help you interpret the results.  For example, you may be below the OSHA PELs, but exceed the Threshold Limit Values (TLVs) set by the American Conference of Governmental Industrial Hygienists (ACGIH) or the National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limits (RELs).  We can help you evaluate solutions which follow the hierarchy of controls: elimination, substitution, engineering controls, administrative controls, and personal protective equipment (ordered from most important to least).
