4. Ven�la�on System:

The vendor will supply an adequate number of air filtra�on exhaust ven�la�on units.

Construc�on:

• The ven�la�on units will be constructed of steel or other durable materials able to withstand damage from rough handling and transporta�on. Provide cabinet widths to accommodate doorways. Cabinet will be factory sealed to prevent material from being released during use, transport, or maintenance. Access to and replacement of air filters will be from intake end.

• The final filter will be HEPA type. Provide filter media folded into closely pleated panels. Completely seal the filter media edges with a structurally rigid filter housing to form a �ght seal. Each filter will be cer�fied by the manufacturer to have an efficiency of not less than 99.97% when challenged with 0.3 um dioctyl phthalate par�cles

• Pre-filters are required to prolong the opera�ng life of the HEPA filter. Two stages of pre-filtra�on are required. Pre-filters will be installed on or in the intake grid of the unit and held in place with a special housing or clamps

• Each unit will be equipped with a Magnehelic gauge or manometer to measure the pressure drop across filters and indicate when filters have become loaded and need to be changed. A table indica�ng the usable air handling capacity for various sta�c pressure readings on the Magnehelic gauge will be affixed near the gauge for reference, or the Magnehelic reading indica�ng at what point the filters should be changed, no�ng the Cubic Feet per Minute (CFM) air delivery at that point

• Each unit will have an elapsed hour meter to show the total accumulated hours of opera�on

• Each unit will have a lockout to prevent the fan from opera�ng without a HEPA filter.

Units will be equipped with an automa�c shutdown system to stop the fan in the event of a major rupture in the HEPA filter or blocked air discharge

• Warning lights are required to indicate normal opera�on, excess pressure drop across the filters and inadequate pressure drop

Provide a fully opera�onal ven�la�on system with the work area maintaining con�nuously a pressure differen�al across the work area containment of 0.02 inches of water.

Prepara�on of Work Area:

Opera�on of System during Abatement:

• Operate system con�nuously to maintain a constant reduced air pressure un�l decontamina�on of the work area is complete. Do not turn off units at the end of the work shi� or when abatement opera�ons temporarily stop. If failure of ven�la�on system occurs, immediately stop abatement work and do not resume un�l system is fully opera�ng

• Start removal work at a loca�on farthest from the ven�la�on units and proceed toward the ven�la�on units

• Operate system con�nuously during encapsula�ng procedures

• At comple�on of removal work, allow ven�la�on system to operate to purge the work area with clean makeup air and to remove airborne fibers that may have been generated during removal work

Dismantling the Ven�la�on System:

• Before removal of units from work area, remove and dispose of pre-filters as fungi

(mold) contaminated, clean and seal unit intake and exhaust openings with 6 mil plas�c shee�ng, decontaminate exterior of units and seal en�re unit, except rolling assembly, with 6 mil plas�c shee�ng

Wet Cleaning:

• Accomplish wet cleaning during decontamina�on with lint free towels. Wipe surface once and re-fold to a fresh face of cloth. Proceed in this manner un�l all available surfaces of towel have been used. Dispose of towel as contaminated waste

HEPA Vacuum Cleaning

• Remove small debris with the HEPA vacuum. HEPA vacuum surfaces of pieces too large to be removed by the suc�on of the HEPA vacuum. Pick up such pieces and place in the botom of a disposal bag. Place pieces in bag without dropping and avoiding unnecessary disturbance of material. HEPA vacuum area three feet beyond the loca�on in which visible debris was found. Vacuum in two direc�ons each at right angles to the other.

• HEPA vacuum surfaces in the room star�ng with the ceiling, then vacuum star�ng at the top of the walls and working downward to the floor. Next begin at the corner of the floor farthest from work area entrance and work towards the entrance. HEPA vacuum the floor using a floor atachment with rubber floor seals and adjustable floor to atachment height. Adjust the height so that the rubber seals just touch the floor if carpeted and are within 1/16 inch of hard surface floors. Vacuum the floor in parallel passes with each pass overlapping the previous by one half the width of the floor atachment. At the comple�on of one cleaning, vacuum the floor a second �me at right angles to the first.
