Engineering Controls at C&IH

Engineering Controls

Engineering controls are the first line of worker protection when substitution and other source elimination controls cannot effectively remove the offending agent(s) or adequately reduce worker exposure.

Workplace engineering controls

C&IH has the technical expertise to design and implement engineering solutions to protect workers by minimizing workplace exposures and other safety and health hazards.  Our goal is to minimize or eliminate the need for administrative controls or personal protective equipment (PPE), thereby reducing the potential for worker injuries and decreasing lost time due to accidents or illnesses.  When necessary, C&IH performs a comprehensive job hazard analysis to correctly identify the location and type of hazards requiring worker protection.  All activities conducted by our staff are designed to help clients establish cost effective engineering and other controls to mitigate workplace exposures and hazards.
