Multiple Choice

Which is an example of an engineering control?

Engineering controls reduce or remove hazards by changing the work environment or equipment so exposure is minimized at the source. Installing guards or safety interlocks fits this approach because it creates a physical barrier or automatic safety mechanism that prevents access to moving parts or stops the equipment if a guard is removed. This change to the equipment itself lowers risk without relying on worker behavior. PPEs, training, and job rotation are administrative or personal protective measures rather than changes to the system. PPE relies on individuals wearing protective gear, training aims to improve safe practices, and job rotation changes who performs tasks or how long they do them. None of these alter the hazard itself like an engineering control does.
