F11 Cleaning Procedures For 114 Liberty Street

a) Tenants and/or owner shall identify items for cleaning with clearly legible tags. Tenants and/or owner, as applicable, shall make the final decision on cleaning or disposal of items. Items shall be cleaned by wet wiping and/or HEPA vacuuming procedures, as appropriate. Compressed dry air (low pressure) may be used to blow debris/dust from openings/crevices in the items. HEPA vacuuming must be preformed in conjunction with this procedure. Care must be taken not to damage the items.

b) Items identified for disposal (untagged) shall be double-wrapped in 6-mil polyethylene sheeting and labeled as ACM waste or bagged in labeled ACM waste bags. The cleaning of items to be disposed is not required.

c) Built-in items, if present, shall be wet wiped and HEPA vacuumed. The contractor shall be responsible for moving built in items that may impede access to surfaces that require clean up. However, the cleaning contractor is not responsible for the reinstallation of said items or any damage related to the removal of built-in items. Care shall be taken not to damage the items whenever possible.

d) Kitchen stoves, refrigerators, dishwashers, etc. shall be wet wiped and HEPA vacuumed, and shall remain in the units.

(20) The Air Sampling Technician shall perform air sampling after the area is free of dust accumulations as determined by the Project Monitor. The apartment will be re-cleaned and retested if the clearance criteria are not achieved.

Refer to the monitoring specification for this information.
