The HCBI doors are unlocked 8AM-7PM Monday to Friday. If you require access to the facility outside these hours, and have completed your general lab safety training and the commercial laser safety training programs through the EHS website, you can request after-hours access from hcbi_admin@fas.harvard.edu. After-hours access is only granted to undergrads after they have been using the facility for a few weeks and demonstrate that they are well versed in the use of the equipment (this does not apply to courses using the facility).
