Office of Environmental Health & Safety

Office of Environmental Health and Safety: provide health, safety, and environmental guidance and services for the campus

Responsibilities include: • Biosafety• Food permits• Indoor air quality

Contact: Phil Maynard, Laboratory Safety Specialist• Lead for inspection of over 1,200

fumehoods on campus

Exhausted Laminar Flow

(ELF) Hood

Vented Sink

Gas Cabinet

Different ventilation systems documented on different databases

Standard forms for all databases Hard to obtain useful information Difficult to compile reports from

several separated databases. Inaccurate/Nonspecific data due to

use of standard forms

Created a prototype database using MS Access including all crucial elements

Developed queries to get information from the database

SELECT t.time_period,COUNT(t.ventSysID) AS NumSysEvalsFROM Inspection_Timeslot AS tGROUP BY t.time_period;

SELECT VS.VSIDFROM Ventilated_System AS VSWHERE EXISTS ( SELECT * FROM Violation, Vent_Violations WHERE Vent_Violations.ventSysID = VS.VSID AND Violation.VID = Vent_Violations.violationID AND Violation.date_recorded - Date() < next_days) OR
