List four examples of common engineering control

Engineering controls are possible interventions intended to reduce worker exposure to biological,chemical and physical agents. They are divided into two categories, ventilation and non-ventilation controls. Ventilation controls are designed to control contaminants once released,like introducing clean air to a workplace, replacing contaminated air. Non-ventilation controls reduce process emission rate, like use of well fitting lids to liquid containers.
