The utility panel(s) are located inside the workplace along both sides of
the hood and are used to access the plumbing for the water, air and gas
outlets which are located next to the panel (s).

What part of the fume hood are you referring to when you say =93utility
panel=94? If you are talking about the back where the small openings are
inside the work area, then yes you are absolutely right. I know this as the
baffle (or with our enclosures the plenum). It is specifically designed for
best air flow with this in place. ****

Hello Everyone,
When the utility panel on a chemical fume hood is missing is it safe to
allow work to be preformed in the hood?
I would say work (synthesis, toxic gas use and powder decanting) should
not be preformed until the panel be replaced for the following reasons:
1. Eddyies in the hood are likely to be form which may cause loss of
containment.
2. Chemicals vapors are going into areas where they are not suppose go and
may cause deterioration of the plumbing and joints
3. High Performance and Low flow hoods would be especially vulnerable to
the loss of work space integrity.
Would anyone have a policy on hood repairs like the above or comments?
As always, thank you for your thoughts in advance.
Mary Ellen
