The Lab Safety Manual has these following revisions added to the original document. They have been added to the main text of the online (html) version of the Lab Manual and will soon be added to the PDF version of the manual. Please call EH&S with any questions.
Biological Hazards and Control

All work with microbiological agents should follow the CDC/NIH guidelines for the appropriate BioSafety Level. At a minimum, research and instructional labs conducting work with microbiological agents should follow the guidelines for BioSafety Level 1 (BSL1). If you are uncertain concerning which biosafety level your work should be considered, call the EH&S Chemical and Laboratory Safety Division at 471-3511 for assistance.
This revision replaces the first full paragraph, page 54, in the section entitled "Biosafety Levels," of the Laboratory Safety Manual (11/96).

Labeling Hazardous Chemical Containers

Signs and Labels
Identify labels, showing contents of containers and associated hazards. Labels on all
incoming chemical containers cannot be removed or defaced (unless the container is empty
and ready for disposal). (When a chemical is transferred from the original container
into another container, e.g. a solvent wash bottle, for other than immediate use, it is
called a secondary container.) Secondary containers must be labeled with the name of the
chemical as it appears on the MSDS. This does not apply to reaction vessels or to benchtop
research apparatus in active use.
(Note: The PI or Lab Supervisor is responsible for compliance with this labeling requirement.)
For more information concerning labeling containers of hazardous materials, call the EH&S Chemical and Laboratory Safety Division at 471-3511.
This revision replaces the 3rd bullet, page 13, in the section entitled "Signs and Labels," of the Laboratory Safety Manual (11/96).

Compressed Gas Cylinder Cabinets
Need a hard copy (PDF) of this document? Download PDF version.
Cylinders containing the compressed gases listed below must be kept in a continuously, mechanically ventilated enclosure. Full size cylinders must be stored in a gas cylinder cabinet. No more than two small cylinders can be stored in a chemical fume hood, a storage cabinet under the fume hood (if properly ventilated into fume hood exhaust), or some other ventilated enclosure. Compressed gas cylinder cabinets purchased by P.I.s must meet Article 80 of the Uniform Fire Code including the following requirements: negative pressure in relation to the surrounding area with the exhaust from the cabinet going to the outside of the building, self-closing doors, and internally sprinkled. Cylinders stored in compressed gas cylinder cabinets or other ventilated enclosures must be secured at all times. When stored in a cabinet or hood, small cylinders must be positioned and secured so that they will not fall out.

Recognizing that because of age or physical constraints, as determined by The University's Physical Plant, a facility may not be able to comply with these requirements, notification of non-compliance, the associated explanation, and a copy of the Physical Plant determination must be sent to Environmental Health & Safety as well as to the Department Chair and College Dean. As modifications can be made to the building, labs will be brought into compliance. In the interim, compressed gases listed above must be used in quantities which will fit into existing ventilated enclosures or justification must be provided explaining why this is not possible. These justifications must also be submitted to the office listed above.
This replaces the section entitled "Compressed Gas Cylinder Cabinets," on page 12 of the Laboratory Safety Manual.
