Engineering controls safeguard employees by eliminating dangerous situations or by erecting a barrier between the employee and the risk. Examples include machine guards to protect the worker or local exhaust ventilation to capture and remove airborne pollution.
What is the difference between engineering control and administrative control?
Engineering controls could involve altering the weight of the products, adjusting the heights of the work surfaces, or getting lifting equipment. Administrative controls are workplace policies, practices, and processes that reduce the likelihood of risky situations for employees.
