What did NIOSH find when it sampled air at the FAA New York Air Route Traffic Control Center?
NIOSH reported no asbestos fibers in the area air samples collected during its October 1980 survey, while still recommending periodic monitoring of sprayed-on asbestos surfaces so dislodgement could be detected.
Documented evidence
- NIOSH sampled area air at the New York Air Route Traffic Control Center in Ronkonkoma on October 7, 1980.
- The area samples did not reveal airborne asbestos fibers during that survey.
- NIOSH nevertheless recommended periodic monitoring of sprayed-on asbestos surfaces to ensure material was not being dislodged.
What the record does not establish
A negative measurement at one survey time does not establish that airborne asbestos was absent during earlier or later disturbance, maintenance, renovation or deterioration.
Why this becomes graph value
The record is published as a reconstruction object, not a list entry. Legacy preserves the source, time context, material or task context, and the boundary between documentation and inference so the same evidence can support more than one historical question without being overstated.
Next reconstruction questions
Useful next questions include: What years? Which building, department, vehicle, machine, trade or maintenance task? What records, specifications, photographs, purchase documents, union records or coworkers can narrow the history?
