Primes¶
- Exposure Pathway
- Exposure pathway exposes several structural facts. Severability: a pathway with one severed link transmits no exposure regardless of how many other links remain, so the whole pathway's risk depends on the minimum link reliability, not the average — which drives both defence-in-depth and single-point-of-failure analysis. Branching: hazards usually have several pathways to the same target, so counting one underestimates exposure and severing one leaves the others open; the right object of analysis is the pathway Η set, not a single pathway. Asymmetric cost: the cost of severing varies wildly by link, with the cheap link often near the source (containment) or the receptor (protective equipment) and the expensive middle (transport medium) hardest to address, which is exactly what hierarchies of control exploit.
This sourceThe control hierarchy (elimination, substitution, engineering, administrative, PPE) exploiting the asymmetric cost of severing a hazard pathway at different links from source to receptor.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
