Our work focuses on objective exposure assessment, defensible data collection, and clear interpretation to support regulatory compliance, worker protection, and informed decision‑making.


Chemical Exposure Monitoring Services

We perform personal and area air monitoring for a wide range of chemical hazards, including but not limited to:

• Gases and vapors
• Volatile organic compounds (VOCs)
• Acid gases and corrosive compounds
• Aerosols, mists, and fumes
• Particulate and nuisance dusts not limited to silica
• Reactive and oxidizing chemicals
• Mixed chemical environments common in laboratory and production settings


Sampling strategies are selected based on the specific materials, processes, and tasks being evaluated.


Laboratory, Industrial & Field Applications

Chemical exposure monitoring services are commonly provided for a wide range of operational environments, including:

• Research, analytical, and quality‑control laboratories
• Manufacturing, processing, and industrial facilities
• Mining, aggregate, and mineral processing operations
• Power generation and utility facilities
• Chemical manufacturing, compounding, and blending operations
• Materials handling, packaging, and bulk transfer activities
• Maintenance, cleaning, turnaround, and change‑out operations
• Facilities with multiple concurrent chemical hazards and exposure pathways


Projects may involve single‑chemical evaluations or complex multi‑chemical exposure assessments, depending on facility operations, processes, and work tasks.


Sampling Methods & Evaluation Approach

Hutzel & Associates selects appropriate sampling methods based on the chemical of concern, exposure pathway, and applicable regulatory or guidance criteria. Our approach may include:

• Personal breathing‑zone air sampling
• Area or task‑based air sampling
• Integrated, short‑term, or full‑shift sampling, as appropriate
• Laboratory analysis through accredited laboratories
• Comparison of results to applicable OSHA Permissible Exposure Limits (PELs), ACGIH Threshold Limit Values (TLVs®), or other relevant criteria


Results are interpreted in the context of work practices, duration, and exposure variability.


Surface Dust, Residue & Supplemental Sampling

When appropriate, chemical exposure evaluations may also include:

• Surface dust or residue sampling
• Housekeeping effectiveness evaluations
• Sampling to support hazard identification or control verification


These services are performed as part of an industrial hygiene assessment and do not include remediation or cleanup services.


Integration With Exposure Control & Compliance Programs

Chemical exposure monitoring may be provided as a standalone service or integrated with broader occupational health and safety support, including:

• Exposure assessments and hazard evaluations
• Respirator selection guidance and respirator fit testing
• Development or review of written programs (e.g., Respiratory Protection, Hazard Communication)
• Engineering and administrative control recommendations
• Documentation to support regulatory compliance or internal programs
