Utilizing engineering controls is regarded as the best method for controlling or eliminating hazards because this approach focuses on the modification of the work environment to reduce or eliminate the exposure to hazards at their source. Engineering controls may include the use of machinery, ventilation systems, or physical barriers that can effectively minimize risks without relying solely on human behavior or effort.

By addressing hazards directly through design and system changes, engineering controls provide a more reliable and sustainable solution for workplace safety compared to other methods. While personal protective equipment is necessary for safeguarding employees, it does not eliminate hazards; it only protects individuals from potential harm. Employee training is crucial for awareness and safe practices but still relies on correct implementation from the workers. Administrative controls involve changes in work policies or procedures that may be effective but can be inconsistent and may not provide the level of protection that engineering controls do.

Therefore, engineering controls are prioritized in safety practices because they lead to significant improvements in risk management by fundamentally altering the way work is carried out.
