A tester's contribution to a safety culture is characterized by a safety-oriented mindset. This involves understanding that their work is part of a larger system where failures can have severe consequences. Therefore, the tester must always consider the overall context of product development, including its intended use, operational environment, and safety goals, when performing their testing activities. This holistic view ensures that testing is not just a mechanical check against requirements but a meaningful contribution to the overall safety of the product. This approach is fundamental to embedding safety consciousness throughout the development lifecycle.

A. The primary responsibility for performing hazard analysis and risk assessment (HARA) lies with safety engineers or a dedicated safety team, not the tester.

C. While testers may identify potential hazards during their work, the formal and systematic analysis of hazards is a distinct safety engineering activity, not a primary testing task.

D. Creating the hardware-software interface specification is a system architecture or design task, not a responsibility of the tester, who verifies against this document.

Section 1.2.3, "Role of the Tester in a Safety Culture," page 10: "The tester contributes to the safety culture by having a safety-oriented mindset. This includes, for example, taking the overall context of the product development into account when executing his/her tasks." This directly supports option B.

Section 1.2.3, page 10: "The tester supports the hazard analysis and risk assessment by providing information about identified defects." This clarifies that the tester supports but does not perform the analysis, invalidating options A and C.
