Workplace Odor Surveys & Assessments

When your space has an unidentifiable odor, a professional odor assessment can help you determine the cause and risk level. A persistent odor in a building indicates the presence of an issue in need of resolution to promote the occupants' wellbeing and safety and avoid negative health effects.

While some odor compounds cause a minor nuisance, others can create a significant health hazard. A workplace odor survey will keep your employees safe and improve their quality of life. Our odor survey consulting services will give you the information you need to eliminate the smell.

The IAQ experts at 1Source follow a protocol with a successful history of identifying both external and internal odors. Our process determines if the smell comes from the building's systems and processes, occupant activities or outside the building.

When we conduct an odor survey, we implement our knowledge of building systems and operations and use the survey data to prioritize actions. We also understand potential odor-generating sources that can contribute to the issue.

Factors to Consider Before an Odor Assessment

Prior to conducting an odor assessment, our team needs to put the odor into context. We'll gather information that helps us understand what steps we need to take to address the odor. Our professionals seek out the answers to the following questions:

  • Where do the building occupants smell the odor?
  • When does the odor happen, and when did it begin?
  • Does the odor's presence accompany any patterns?
  • Can occupants detect the odor above ceilings?
  • Does the odor occur near a janitor's closet?
  • What does the odor smell like and at what intensity?
  • Does the weather impact the odor's intensity or presence?
  • Can you detect the odor before employees come into the building?
  • Does the odor occur in an area served by a certain air handling unit (AHU)?
  • Who perceives the odor?
  • Does the building shut down the HVAC systems overnight?
  • Can you smell the odor over the weekends?
  • Does the odor occur during the night?
  • Are there health effects believed to be caused by the odor?

Finding the answers to these questions will allow us to understand the potential source of the odor.

The Workplace Odor Survey Process

During a professional odor assessment from 1Source, our team will:

  • Interview management and other staff
  • Gather general information about the facility
  • Visit the site of the odor and collect relevant data
  • Record the source of the odor and its emissions
  • Sample the air near the odor and its potential sources
  • Analyze samples in a laboratory
  • Report analysis results and assessment findings

Once we determine the source and nature of the odor, we can recommend actions for remediation.

Odor Remediation and Consulting Options

The steps taken to resolve an odor issue depend on the source of the odor and its hazard level. The results from a odor survey may drive us to recommend actions such as:

  • Performing further IAQ testing for mold, bacteria and other contaminants
  • Repairing or replacing HVAC systems, plumbing or another building component
  • Exterminating pests that cause disease and odor
  • Removing pollutants and gases

After overseeing the remediation process, we'll conduct a final assessment to determine the elimination of the odor and its source.
