Final answer:
Engineering controls are considered the most important type of safety control as they manage hazards at the source and are built into the design of equipment or processes to reduce exposure to risks. option c.
Step-by-step explanation:
The most important type of safety control is C. Engineering. Engineering controls are the preferred method of managing hazards in the workplace because they are designed to remove the hazard at the source, before it comes into contact with the worker. These types of controls are built into the design of a facility, equipment, or process to minimize the production, release, or exposure to hazardous materials or situations. Examples include installing ventilation systems to remove airborne contaminants, using sound-dampening technology to reduce noise levels, and designing equipment that eliminates the need for manual lifting. Administrative controls and work practice controls come next as they relate to how work is organized and performed. Personal protective equipment (PPE), like safety helmets and ear protectors, is also vital but is considered the last line of defense. It is used when there are remaining risks that cannot be adequately controlled by other means.
