The case of intoxicated cells-an epidemiologic note
American Journal of Epidemiology
|March 1, 1981
Summary
Toxic exhaust fumes recirculated into a research institution, contaminating tissue cultures. This occurred via elevator shaft ventilation systems, highlighting a potential risk in building design for airborne contamination investigations.
Area of Science:
- Environmental Health
- Occupational Safety
- Laboratory Medicine
Background:
- Airborne contaminants pose risks in laboratory settings.
- Building ventilation systems can inadvertently recirculate hazardous materials.
- Elevator shaft cooling mechanisms are common in modern buildings.
Purpose of the Study:
- To describe an incident of laboratory intoxication due to recirculated toxic fumes.
- To identify the specific route of contaminant entry.
- To raise awareness about potential risks in building architectural designs.
Main Methods:
- Case description of a tissue culture intoxication incident.
- Investigation of the building's ventilation and elevator systems.
- Analysis of fume hood exhaust and air intake pathways.
Main Results:
- Toxic exhaust fumes were reintroduced into the building.
- A pathway was identified involving elevator shaft cooling systems.
- Elevator movement created suction, drawing contaminated air into occupied spaces.
Conclusions:
- Elevator shaft cooling systems can act as conduits for airborne contaminants.
- Such mechanisms should be considered in epidemiological investigations of unknown intoxications.
- Building design requires careful evaluation to prevent environmental health risks.
