Real-Time Root Causes Assessment
INSIGHT INTO REAL-TIME ROOT CAUSES ASSESSMENT SERVICES
Full-shift exposure sampling (typically using pumps and filter media, see picture at left) is the choice method in establishing compliance with OSHA regulations. Such samples produce a single 8-hour time-weighted average (TWA, see example results below) that is directly comparable to OSHA PELs and Action Levels, which are often full-shift limits.

Instead of one number, real-time monitoring methods can create thousands of measurements, all potentially linked to worker/facility activities through observations, activity logs, production data, and even video/audio recordings.
The collected data can be statistically evaluated in a number of ways to determine correlations that can be targeted for controls. Below are several examples of the root causes that are commonly observed in industrial environments.
