After hours lab work
The Safety Committee recommends that any member of the Macdonald Community performing laboratory duties alone during quiet hours (when no porter is on duty) contact Campus Security by telephone.
People planning on late work should let security know when the work will start and in which laboratory it will be performed. When completed, they must re-contact security to confirm that the work has been completed and that they are leaving the area. This will end the personal safety monitoring period.
Dangerous laboratory work
When possible, laboratory Work (which involves some danger) should be restricted to normal working hours.
If it is essential to perform these studies during card access operation periods, the work should be conducted with a second person present in the near vicinity. The "buddy system" is good laboratory practice.
