Understanding exposure under real operating conditions

Representative exposure monitoring helps organizations understand how conditions vary across tasks, shifts, materials, production rates, operating states and control performance. A well-designed sampling strategy reflects those differences and is aligned with the decisions the organization needs to make.

Onterris combines qualitative assessment, field observation, direct-reading instruments, personal and area sampling, laboratory analysis and technical interpretation to build a clear picture of how exposure occurs. Our industrial hygiene, chemistry and toxicology expertise helps clients identify affected worker groups, evaluate control performance and establish a defensible basis for action, communication and future reassessment.

Supporting Your Industry

Organizations rely on representative exposure monitoring and assessment to understand changing workplace conditions, evaluate control performance and make informed decisions about worker protection.
why it matters

Better exposure data leads to better control decisions

A well-designed assessment captures the work conditions that matter and produces findings that can guide worker protection, resource allocation and regulatory decisions.
  • Exposure assessment should reflect differences in task, shift, production rate, material and control performance
  • Sampling strategies should account for peak, intermittent and nonroutine conditions
  • Representative data helps characterize risk across groups of workers with similar exposure potential
  • Reassessment may be needed as processes, equipment and staffing change
  • Clear findings support timely decisions about controls, medical follow-up and worker communication

Design assessments to deliver decision-ready exposure data

Onterris develops assessment strategies around the process, workforce, hazards and decisions that matter, targeting conditions that accurately represent how work is performed. By combining field observations with measurement data, our teams provide practical recommendations grounded in real workplace conditions.
