Objects anchor memory

Equipment and materials worth identifying

The objective is not to assume that one of these items contained asbestos. It is to identify the exact equipment or material category so product history, specifications, maintenance records and coworkers can be investigated.

Place layer

Current H&S workplace records that share published metadata

These are navigation candidates based on the metadata already attached to H&S source-led workplace records. The link itself is not evidence that building maintenance & facilities workers worked there or that the site involved the same material.
