No asbestos-contaminated items shall enter this room. Workers enter this room either from outside the structure dressed in street clothes or directly from the showers. This room shall be reasonably heated or cooled. This room shall be separated from the outside by poly barriers (Z flaps) or a door (lockable, if located outside the building).

3.1.4.5. Shower Room: This is a separate room used for transit by cleanly dressed workers entering the job from the clean room or by workers showering after undressing in the equipment room. The shower stall shall have two open sides and be set up to allow a single pass through between the clean room and equipment room and be built with rigid sides and top. Shower water shall be filtered. No leakage of shower water to the outside of the shower is allowed. Shower drain water shall be filtered with a 5 micron filter. Any leakage to the outside is to be considered contaminated. This room shall be separated from the clean room and equipment room by an airlock using by poly barriers (Z flaps). The shower room shall provide hot and cold running water and soap and towels.

3.1.4.5.1. Shower Stall: Provide leak tight shower enclosure unit with integrated drain pan fabricated from fiberglass or other durable waterproof material. Equip with hose bibs for hot and cold water. Arrange water shut off and drain pump operation controls so that a single individual can shower without assistance from either inside or outside of the abatement work area. Provide splash proof entrances. Provide back flow prevention device and vacuum breaker, where required. Connect drain to a reservoir, pump water from reservoir through filters to a drain.

Mount filters inside shower stall in manner that allows for access for filters to be changed from inside the shower. Change filters daily or more often if necessary.

3.2. Asbestos Work Area Preparation (General)

The Work Area is the location where asbestos abatement work occurs. It is a variable of the extent of Work of the contract. For this project a "Work Area" is defined as the area in which asbestos removal is being performed. A "Work Area" is considered contaminated during the Work, and must be isolated from the balance of the building, and decontaminated at the completion of the asbestos-abatement work.

3.2.1. Completely isolate the Work Area from the outside so as to prevent asbestos containing dust or debris from passing beyond the isolated area. Should the area beyond the Work Area(s) become contaminated with asbestos containing dust or debris as a consequence of the Work, immediately stop all abatement work and clean those areas. Perform all such required cleaning or decontamination at no additional cost to Owner.

3.2.2. Prior to any asbestos related activities, the Contractor shall have a locked waste container on site.

All equipment and wiring shall be in compliance with National Fire Protection Association Standard 70, and the National Electrical Code.

3.4. Asbestos Work Area Preparation (Mini Enclosure)

The Work Area is a variable of the extent of Work of the contract. For this project a "Work Area" is defined as the area in which asbestos removal is being performed. A "Work Area" is considered contaminated during the Work, and must be isolated from the balance of the building, and decontaminated at the completion of the asbestos-abatement work.
