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.
What are the basic principles of engineering controls?
- Redesigning a process to use less dangerous chemicals;
- Redesigning a piece of equipment to eliminate the source of high temperatures, noise, or pressure;
- Designing general ventilation with enough fresh outdoor air to improve interior air quality and generally to provide a safe, healthy environment.
- Redesigning a workstation to reduce physical stress and remove ergonomic dangers.
