Airborne Chemical Monitoring Station

Occupational exposure to chromium(VI) (Cr6+) is 8x more likely to result in cancer than asbestos. Workers are exposed to airborne Cr6+ when aged coatings are stripped by abrasive blasting inside blast cleaning rooms (BCR) with insufficient airflow. Simply increasing airflow to reduce exposure is an expensive proposition. Energy costs increase exponentially when fixed parameter airflow is used to mitigate airborne toxin exposure. Therefore, there is an urgent need to manage exposure at reasonable cost.

Figure Engineering is developing an innovative approach to reducing airborne toxin exposure while maintaining reasonable BCR operating cost to dependably meet changing safety standards.
Through BCR instrumentation, Figure quantifies and differentiates airborne toxins and continuously compares sensed BCR conditions to known hazardous limits to enact autonomous ventilation system response. With the addition of Figure’s Dust Migration Mapping™ technology – which is reliable, robust, and economical – diagnostic validation is employed to support routine monitoring for safety and compliance.
