Lab and Building Security
Excerpted from the Chemistry Department Safety Newsletter Issue #7
October 24, 2001

Doors
1. Chaseway end doors must be kept locked at all times. They may not be propped open at any time.
2. All doors must be locked when offices and labs are unoccupied. You may leave the room for a few minutes, but if you will not be returning shortly, you must lock the door behind you. Note that locked door status will be checked by the Safety Committee, and problems will be reported to the Director of Labs.
3. When labs are occupied, doors should be kept open for safety reasons. In an emergency, you may need to call for help from neighbors, or to quickly access the phone in a nearby lab - some of the labs do not have phones. Moreover, OSHA standards require unimpeded access to safety showers without an intervening closed door and in our building safety showers are located in the corridors outside the labs.
4. In the instructional labs, two doors will be kept open when classes are in session.

Storage
1. Radioactive materials and pathogens must be locked up and secured at all times.
2. Chemicals stored in chaseways must be kept out of view. For this reason, glass-door cabinets and open shelving may not be used for chemical storage in chaseways.
3. In the following categories, chemicals stored in labs will also be out of view:
a. Hazardous chemicals whose names would be popularly recognized, such as cyanide, strychnine, arsenic, etc.
b. Large containers (kilogram quantities) of highly toxic or otherwise hazardous chemicals.
c. Large containers of even moderately dangerous chemicals if not frequently used.

Building Security in the Evenings and on Weekends
1. You have been issued a building key. It is for your use only. Never admit another person into the building at times when the building is locked, unless you know the person has a right to access.
2. Further building security rules will be implemented in the near future.
