Colchester Research Facility
Fume Hood Proximity Sensors
Chemical Fume Hoods located in the pre-existing UVM labs of Colchester Research Facility have proximity sensors on them. The Phoenix Controls proximity sensor is located just above the sash on the face of the hood. If the sensor recognizes movement in front of the hood, it goes into an "occupied mode" which increases the face velocity of the fume hood to approximately 100 feet per minute (fpm). If there is no activity in front of the fume hood, the sensor goes into an "unoccupied mode" which reduces the face velocity of the fume hood exhaust to approximately 80 fpm. This face velocity reduction is a basic energy saving feature.
In the renovated labs of Colchester Research Facility:
Emergency Gas Shutoff
Every lab is equipped with an “Emergency Gas Off” system. This consists of a large red mushroom switch on the wall labeled “Emergency Gas Off”. When this switch is depressed, natural gas to the lab will shut off. Only authorized personnel are permitted to reset gas flow once the “Emergency Gas Off” system has been engaged. Should you accidently push this button please contact Physical Plant at 656-2560 to have it reset.
Instances requiring use of EGO button. (Approved by John Marcus)
Button should be pushed as personnel exit the laboratory.
- Smell of gas in the laboratory.
- Fire alarm.
- Earthquake, storm, explosion or other event causing structural damage which might compromise gas piping system.
Fume hood use
Fume hoods installed in the renovated section of Colchester Research Facility are designed and calibrated to operate safely at a face velocity of 80 linear feet per minute. Operating sash height for these hoods is 18”s and is indicated by a marker on the sash opening. Should it be necessary to open the sash above the 18” mark do so slowly to allow the duct controls to adjust the air volume to the hood and maintain a safe working area at the face of the hood. When returning the sash to the 18” height, again do so slowly and allow the controls to stabilize (10-15 seconds) before resuming work. As with all fume hoods try to conduct your work at least 6 inches inside the sash opening.
When not in use, lower the sash to the lowest possible point. For more information on the proper use of fume hoods please go to: http://www.uvm.edu/~esf/chemicalsafety/fumehood.html
Cold room emergency alarms
In each of the new cold rooms (142, 177) next to the door on the interior of the cold room is a small red push button positioned next to the door. When pushed, this button activates an audible alarm to indicate that someone is unable to exit the cold room. The button is reset by pulling it back out.
Safety showers and eyewashes testing requirements
All Safety showers are required to be tested on a weekly basis. Testing equipment is kept in the building machine room which can be accessed by contacting Russ Charron or Pat Porter. If you are unsure of how to conduct the shower test contact Chris Gebo at 656-4341. He will be glad to give instruction to anyone needing it.
Eyewash units also need to be tested on a weekly basis. Contact Barbara St. Gelais at 656-5400 for instructions.
Overhead storage of items in the Laboratory
Materials must not be stored in areas where the will interfere with sprinkler operation. This means that they must be place at least 18 inches away from any sprinkler heads.
Delehanty is one of the few buildings on campus that has a neutralization tank for the disposal of weak acid solutions. A specific Sink Disposal Agreement has been designed by Environmental Safety and the UVM Geology Department and has been approved by the City of Burlington. Contact us for specifics as to which acids are appropriate for disposal in this system. Only lab sinks with blue plumbing below the sink lead to the neutralization tank on the first floor. No hazardous waste other than weak acids may be poured down these drains in Delehanty.
Cosmo Lab/Rm 305
Clean room/lab accessible by lab personnel only. Electronic key FOB entry. Only vestibule is accessible by non-lab emergency personnel. Arrangements can be made with Paul Bierman directly to access lab.
Fume Hood Controls
There is a toggle switch on the wall of each lab (sometimes hidden behind appliances or other equipment) that regulates the airflow to each chemical fume hood. When the room is occupied, the toggle switch should be in the "occupied" position. To save energy, the last person leaving the lab should put the toggle switch back to the "unoccupied" position. Each fume hood also has a face velocity sensor with an alarm. This sensor monitors the velocity of air passing through the fume hood and will alarm when an unsafe condition is detected. Please do not "mute" or tape over your fume hood alarm.
Marsh Life Science
Marsh Life Science has Variable Air Volume (VAV) Hoods. This means that as the fume hood sash is lifted, an air velocity sensor within the fume hood detects the change in air velocity and the air control valves modulate so the air velocity maintains 100 feet per minute (fpm) at the face of the fume hood.
Each fume hood also has a face velocity sensor with an alarm to monitor the velocity of air passing through the fume hood. This alarm sounds when a face velocity of less than 100 fpm is detected. Please do not "mute" or tape over your fume hood alarm. If the alarm sounds consistently, please notify Physical Plant to have the hood repaired.
Some air velocity alarms are also interlocked with the room's light switch. In these spaces, an alarm will signal if the sash is left open and the room lights are turned off. Always close the fume hood sash and shut off the lab lights when leaving the lab.
