||NFPA 45 - Laboratories Using Chemicals
6-8.3 Laboratory hood sashes shall be kept closed whenever possible. When a fume hood is unattended, its sash shall remain fully closed.
Iroquois Hoods is now offering the New-Tech Automatic Sash Positioning System (ASPS) which protect lab technicians by automatically closing the sash when they walk away. Thus, a closed sash protects them from the hazards within the fume hood. In addition to closing the sash, the ASPS detects the technician approaching the fume hood and automatically opens the sash. This leaves their hands free and creates a barrier-free work environment.
In high traffic areas, a push button is added to activate the sash opening function. When the ASPS is installed on a fume hood with Variable Air Volume (VAV) fume hood controls for constant face velocity, the savings in energy can pay for the ASPS in typically less than two years when compared to an open sash.
