Annual Report on Project XL Activities
at
Prepared by N.
Introduction
This report contains the findings and observations of the
most recent year of
Management of
Hazardous Chemicals of Concern (EPIs 1 & 2)
Laboratories are required to submit complete chemical
inventories to the Office of Environmental Health and Safety annually. These inventories are used by us to meet
regulatory requirements, including emergency planning, Tier II and emission
source registration reporting. We
compare the HCOC list to the main inventory in order to identify HCOCs in
various locations in labs. The HCOC list
is also used to identify particular chemicals for targeted clean-out or
maintenance (e.g. ethers, picric acid). In
the past year we have used the HCOC list in developing a protocol for limiting
lab activities when there is a significant event on campus[1] (e.g.
football game, commencement, Boston Marathon).
By sorting the HCOC list based on certain parameters (e.g. Class 1A flammables
[Table 1] and reactive chemicals [Table 2]), we have been able to provide labs
with a discrete list of chemicals whose use is prohibited during significant
events when there are large numbers of people on campus and emergency response
to campus is difficult. In addition, the
HCOC table is used to provide information on chemical storage of unstable
chemicals.

events.)
