When leaving the plant spaces, work clothing and boots will be required to be removed and
stored in the workers’ respective dirty locker room. In their respective adjoining shower room,
facility workers will wash off any dust which may have contacted their skin. Clean towels will
be provided in the clean locker rooms, which are the designated areas for facility workers to
change back into their street clothing before proceeding to the lobby and exiting the building.
Authorized visitors to the facility will be required to doff their disposable protective coverings in
the appropriate dirty locker room, and wash their hands prior to entering the clean areas of the
building.
A laundry room is provided in the hygiene area for washing and drying work clothing; work
clothing will not be allowed to leave the building. In an effort to further prevent the spread of
potential contamination, facility workers will be prohibited from washing or drying street
clothing and other clean linens at the proposed TSF.
1.1.3 Office/Plant Area Separation
Within the building proper of the proposed TSF, there will be an engineered separation between
the office side and the plant side. This concept is shown in the office layout in Appendix 1-A,
drawing H340940-0000-50-042-0002. The office side will be enclosed and maintained under
positive pressure. The remainder of the building will be maintained under negative pressure. In
addition to engineered barriers, procedures and protocols will be established to ensure that
employee travel between the two sides of the building will not be a source of potential crosscontamination.
The lunch room is only accessible from the office area. Eating, drinking, and the use of tobacco
products will be strictly prohibited anywhere in the plant spaces. Smoking will be prohibited on
the proposed TSF compound. Once employees have been in the plant spaces, they will be
required to wash hands, doff work clothes, and change into street clothes before they can access
the lunch room. This protocol is consistent with practices at metallurgical operations and is
intended to protect facility workers from accidental ingestion of mercury. Due to the batch nature
of the process and automation, employees are not expected to be in the process area for extended
periods of time.
There will be a washroom located in the plant spaces which can also be accessed from the
corridor for employee use during shift hours.
Even though the plant spaces are maintained at a lower pressure than the office area and the
outdoor environment, vestibules are in place between these spaces to ensure the pressure
difference between the office and the plant spaces is maintained.
