CAP Retrofit Kit™, as a physical air barrier that fits under an open fume hood sash, offers significant improvement to fume hood containment and safe laboratory operations while offering unobstructed access to the fume hood work bench using the mobile ports which can move independently back and forth through the physical protective barrier film.
 Fume hoods, as laboratory safety devices, are used to
- Contain the toxic, hazardous or obnoxious contaminates and
- Prevent students, researchers, or technicians exposure by taking conditioned laboratory air into the fume hood to dilute fume hood contaminates and then exhausting it directly outdoors.
The CAP Retrofit Kit improves on these primary fume hood containment functions resulting in lower safety risk and improved IAQ within laboratories:
Containment Issue 1: Fume hood contaminates can enter the laboratory facility due to the dynamics of laboratory air flow turbulence that can draw fume hood contaminates out of the fume hood directly into the laboratory.
To counteract the effect of air dynamics within a laboratory OSHA guidelines state that fume hoods should be located within a laboratory to avoid any adverse air turbulence that can cause eddy currents at the face of the open fume hood. These detrimental eddy currents or air turbulence can be produced by
- HVAC air supply distribution patterns;
- People walking past the hood;
- Thermal convection in front of the hood;
- Doors and windows being opened and closed; and
- Movement of the user arms while using the fume hood.
Containment Issue 2: Fume hood contaminates can be transported out of the fume hood into the laboratory facility by accidental spills, splashing or energetic events within the fume hood.
Accidents to do happen when students, researchers or technicians us a fume hood resulting in the exposure of laboratory personnel to toxic and obnoxious contaminates that are blown, spilled or splashed out of the fume hood.
