All non-hazardous materials must also be removed, recycled or disposed of properly. In larger projects, coordination of these activities within a building or department may be useful or necessary. Everything must be disposed of properly. This involves the removal of any residual material from accessible surfaces of lab cabinets, counters and sinks. In the case of a fume hood used for a variety of procedures involving hazardous materials, any residues or condensates shall be removed from the accessible internal surfaces of the fume hood, but not from the inaccessible duct work or other inaccessible areas serving the fume hood.
Occupants are responsible for removing every chemical from the space to be vacated.
Flushing of Sink Drains Immediately prior to vacating the laboratory, all sink drains shall be flushed by running tap water for at least two minutes. Special treatment of the drain plumbing serving the sink is NOT included in the deactivation process. Planning Planning is preventive maintenance and the most important step to making sure that a move goes smoothly. Planning should start several weeks before the actual move to guarantee that everything is transported and reactivated safely and that research can carry on as soon as possible. Suggestions Make room diagrams of each new room so that they can be configured early on in the planning process.
