Primary official sources
Regulators, government agencies, standards bodies, official legislation, recognised professional institutions and original technical documentation are preferred for requirements and definitions.
Trust and evidence
Editorial standards for Safety Nexus.
Safety Nexus publishes practical AI safety, EHS and deployment content under Alvin Liao's name. This policy explains how public claims are sourced, reviewed, bounded, updated and corrected.
Source hierarchy
First-party project evidence
Proof cases describe Alvin Liao's role, problem framing, system design and public artefacts. Private application URLs, confidential data and unverified production metrics are excluded.
Secondary context
Research, industry reports and practitioner commentary may provide context. Important claims are traced back to the original or most authoritative available source where possible.
AI-assisted content policy
AI may assist with research organisation, translation, drafting, visual production, formatting and code. Alvin remains responsible for the published page. High-consequence statements should be checked against a primary source or clearly labelled as professional interpretation. AI output is not treated as evidence by itself.
Human review
Names, dates, standards, roles, prices, project scope and material safety claims are reviewed before publication.
Disclosure and consent
AI-generated or AI-assisted media is described when relevant. Personal likeness and voice use requires permission; client-supplied media remains subject to client rights and consent.
No autonomous safety judgement
Published systems support people and workflows. They do not replace competent EHS, engineering, legal, financial or regulatory judgement.
Proof-case boundaries
A proof page demonstrates a real problem, an implemented or developed system pattern, Alvin's stated role and the evidence that can be shared publicly. It does not imply independent certification, universal regulatory compliance, organisation-wide approval or a performance result unless the page provides a named source and measurement definition.
Updates and corrections
Material pages display publication or review dates in their page metadata. When roles, prices, standards or public evidence change, the relevant page should be updated. To report a factual issue, contact Alvin through LinkedIn and identify the page, statement and supporting source. Confirmed material errors will be corrected rather than silently repeated.
