Exposure Assessments

Any time an employee is involved with work that presents a respiratory hazard or is required

by your company to wear a respirator, an exposure assessment must be conducted. STEP

conducts exposure assessments to help clients characterize the nature and magnitude of

employee exposures to respiratory hazards. At the completion of the assessment, we make

equipment recommendations to help ensure employees are properly protected from

contaminants that are present in the workplace. An exposure assessment must be completed

prior to selecting employee equipment.

The following are examples of when you should consider conducting an exposure assessment.

This is just a guideline, and not a comprehensive list:

  • When OSHA has a substance specific standard (e.g., lead, methylene chloride).

  • When employees notice symptoms (e.g., irritation, odor) or complain of respiratory health effects.

  • When the workplace contains visible emissions (e.g., fumes, dust, aerosols).
