Engineering controls protect workers by removing hazardous conditions or by placing a barrier between the worker and the hazard. Examples include local exhaust ventilation to capture and remove airborne emissions or machine guards to shield the worker. Well-designed engineering controls can be highly effective in protecting workers and will typically be independent of worker interactions. They typically do not interfere with worker productivity or personal comfort and make the work easier to perform rather than more difficult. The initial cost of engineering controls can be higher than some other control methods, but over the longer term, operating costs are frequently lower, and in some instances, can provide a cost savings in other areas of the process.

NIOSH researchers help prevent occupational disease and injury by conducting engineering control technology evaluations and developing practical, solutions-oriented control technology interventions. To conduct these efforts, NIOSH works collaboratively with partners both in the United States and around the world.
