Exposure Monitoring & Sampling
Measuring Workplace Exposure to Support Safety and Compliance
Understanding What Workers Are Breathing and Being Exposed To
Exposure monitoring is used to measure what employees are actually exposed to during their workday. This can include airborne contaminants such as dust, fumes, vapors, or gases, depending on the job and environment.
Sampling is typically performed in real working conditions using personal or area monitoring equipment. The goal is to understand exposure levels over time and compare them to OSHA permissible exposure limits (PELs) and other applicable guidelines.
Clear data allows employers to make informed decisions about controls, protective equipment, and workplace practices.

Frequently Asked Questions
What is exposure monitoring?
Exposure monitoring measures what workers are actually exposed to during their job. This usually involves collecting air samples during a work shift and comparing the results to OSHA exposure limits.
When is exposure monitoring required?
Exposure monitoring may be required when there is a known or suspected workplace hazard, such as silica dust, chemical vapors, or fumes. It is also commonly performed to meet OSHA requirements or verify that existing controls are effective.
What happens if exposure levels are too high?
If exposure levels exceed applicable limits, steps can be taken to reduce risk. This may include engineering controls, changes to work practices, or the use of personal protective equipment. Follow-up monitoring is often used to confirm that those changes are working.
