In HFACS, unsafe acts are described as ...

• A. Latent conditions
• B. Environmental hazards
• C. Unsafe acts by the operator
• D. System design flaws

Answer: (C)

In HFACS, unsafe acts are the direct actions of the operator that lead to an accident. These are the active failures the person commits, including errors (skill-based, decision, and perceptual) and violations (intentional deviations from procedures). This contrasts with latent conditions—underlying systemic factors such as organizational influences, supervision, and preconditions for unsafe acts—that set the stage but are not the immediate actions causing the event. Environmental hazards or system design flaws are typically considered part of those latent or preexisting conditions rather than the unsafe acts themselves. So the description that fits best is the operator’s actual actions that contribute to the mishap.
