Safety, Ethics, and Standards
Obligations Beyond the Spec
Engineering decisions affect people who never sit in the design review. Ethics content on exams tests whether you can identify the conflict and the correct escalation, not whether you can recite a code.
Core ideas:
- Duty to hold public safety paramount - above schedule, cost, and employer preference.
- Competence limits - signing off on work outside your expertise is a violation; the right move is to seek qualified review.
- Honest reporting - data must not be trimmed, selectively presented, or fabricated. Uncertainty is reported, not hidden.
- Conflicts of interest - disclose, and recuse where appropriate.
- Confidentiality and intellectual property - employer information, patents, and attribution.
Standards and regulation: consensus standards (voluntary until incorporated), codes, and regulations (legally mandatory). Compliance with a standard is a floor, not a ceiling. Hierarchy of controls for hazards: eliminate, substitute, engineer controls, administrative controls, personal protective equipment - in that order of preference.
Traps
- A question describes a supervisor pressuring you to approve an unsafe design. The right answer is rarely "refuse and quit"; it is usually to document the concern and escalate through the proper channel.
- "It meets the standard, so it is safe" - false. Standards lag technology and set minimums.
- Confusing a voluntary consensus standard with a legal regulation.
- Assuming safety is only a product property; it also includes labeling, warnings, and foreseeable misuse.
Rule of Thumb
If you would not want the decision printed on the front page, escalate before you sign. Document the technical concern, the evidence, and the people informed - contemporaneous records are what protect both the public and the engineer.
Worked example: Testing shows a component fails at 1.2× rated load, while the internal guideline requires 1.5×. The standard only mandates 1.1×. Correct action: report the shortfall against the internal guideline, do not sign the release, and escalate - meeting the legal minimum does not discharge the duty to flag a known deviation.
