What is the main purpose of engineering controls in a high hazard facility?

The primary purpose of engineering controls in a high hazard facility is to physically modify processes in order to reduce hazards. This approach focuses on designing and implementing systems that minimize the risk of accidents or exposures associated with hazardous materials or processes. By altering the physical state or configuration of equipment and processes, engineering controls aim to eliminate or significantly reduce the potential for harm to workers and the environment.

For example, using ventilation systems to remove harmful airborne contaminants, enclosing machines to prevent accidental contact, or implementing fail-safes in equipment are all engineering controls aimed at enhancing safety. These measures are fundamental in creating a safer work environment and are typically considered a more effective solution than administrative controls or personal protective equipment, which rely on human behavior for efficacy.
