Tuning Ventilation Systems Saves Energy, Reduces Employee Exposure Risk

Are we running exhaust fans enough to keep the air breathable and safe? Are we over-running fans and wasting energy?

Area exposure monitors are ideal for showing airborne particulate concentration over time in a designated area. Personal exposure monitors can do the same, but they also provide usable details about concentrations within the employee’s breathing zone. Used together, the two device types provide effective real-time data for making decisions regarding employee health and ventilation control.

Recently, we helped a customer with a large welding operation. There was visible smoke on the plant floor during operation, so they needed to address both potential hexavalent chrome and total respirable dust exposure. They decided to use the TSI DustTrak DRX handheld unit for area monitoring, and employees started wearing TSI SidePak AM510s for personal monitoring.

The TSI devices were used in tandem to characterize the environmental and breathing area particulate concentrations, and to evaluate several strategies to control ventilation and reduce exposure. With the data from the DustTrak DRX and the AM510s, the customer was able to select the most effective and energy-efficient solution for reducing employee exposures.

Later, IH sampling confirmed dramatic reductions in both chrome and respirable dust exposure. Plus, employees reported being more comfortable in their working environment.
