DHS 163.14(11)(b)(b) Lead-safe work protocol. When supervising or performing renovation activities, documented methodologies shall be used to conduct work in a lead-safe manner that does not create lead-based paint hazards, including work practices and engineering controls that limit the creation of dust and prevent the spread of dust, debris and paint chips outside the work area, and shall comply with all requirements under pars. (c) to (L). DHS 163.14(11)(c)(c) Requirement for supervision. The assigned certified lead-safe renovator or another person who meets the conditions of par. (a) 3. or 4., shall provide direct on-site supervision at all times during worksite setup, including while posting warning signs and establishing work area containments, and shall be onsite regularly during renovation activities to direct work performed by other individuals and to ensure that lead-safe work practices are being followed, that containment barriers are maintained and that dust and debris do not spread beyond the work area. The certified lead-safe renovator shall be readily available, either on site or by telephone, at all times while paint disturbing activities are being conducted and, when off site, shall be able to return to the worksite within a reasonable time, about 30 minutes, as needed. DHS 163.14(11)(d)(d) Requirement for ensuring compliance. The company shall ensure that all renovation activities are conducted according to the requirements of this section and all applicable federal, state and local government requirements are followed.

Documented methodologies and all of the following work practice requirements shall be used to protect occupants when renovation activities are performed: DHS 163.14(11)(e)1.1. ‘Post signs.’ Signs clearly defining the work area and warning occupants and other persons not involved in the renovation activities to remain outside the work area. To the extent practicable, these signs shall be in the primary language of the occupants. Signs shall be posted before beginning the work and shall remain in place and readable until the renovation activities and post-work cleaning verification have been completed. DHS 163.14(11)(e)2.2. ‘Contain work areas.’ Before starting renovation activities, the work area shall be isolated so that no dust or debris leaves the work area during the activity. Workers shall maintain the integrity of the containment throughout the renovation activities by ensuring that any plastic or other appropriate containment materials are not torn or displaced, and taking steps necessary to ensure that no dust or debris leaves the containment work area during the renovation. When the building is occupied, containment shall be installed in a manner that provides safe access to restrooms and exits for occupants. Containment may not be constructed in a manner that would interfere with worker egress in an emergency. DHS 163.14(11)(f)(f) Interior lead-safe work practices. The company shall ensure that documented methodologies are used for all interior renovation activities and that all personal property in the work area is protected from contamination by dust and debris, including all of the following: DHS 163.14(11)(f)1.1. Remove all objects from the work area, including furniture, rugs, and window coverings. Pre-clean all horizontal surfaces with a HEPA vacuum to remove any existing paint dust and debris. Objects that cannot be removed shall first be cleaned using a HEPA vacuum, and then be covered with plastic sheeting or other impermeable material with all seams and edges taped or otherwise sealed. DHS 163.14(11)(f)2.2. Close and seal all duct openings in the work area with taped down plastic sheeting or other impermeable material. DHS 163.14(11)(f)3.3. Close windows and doors in the work area. Doors shall be covered with plastic sheeting or other impermeable material. Doorways used as the entrance to the work area shall be covered with plastic sheeting or other impermeable material in a manner that allows workers to pass through while confining dust and debris to the work area. DHS 163.14(11)(f)4.4. Cover floor surfaces in the work area, including installed carpet, with taped down plastic sheeting or other impermeable material at least 6 feet beyond the perimeter of surfaces undergoing renovation, or a sufficient distance to contain all dust, whichever is greater. Floor containment measures may stop at the edge of a vertical containment system consisting of impermeable barriers that extend from the floor to the ceiling and that are completely sealed at joints with the floor, ceiling, and walls. DHS 163.14(11)(f)5.5. Use precautions to ensure that all personnel, tools, and other items, including the exteriors of containers of waste, are free of dust and debris before leaving the work area. DHS 163.14(11)(g)(g) Exterior lead-safe work practices. The company shall ensure that documented methodologies are used for all exterior renovation activities and that all personal property in the work area is protected from contamination by dust and debris, including all of the following: DHS 163.14(11)(g)1.1. Remove all objects from the work area, including furniture and play equipment, and pre-clean horizontal surfaces and the ground to remove any visible paint debris.

Close all doors and windows within 20 feet of the renovation work area. On multi-story buildings, close all doors and windows within 20 feet of the renovation work on the same floor as the renovation and all doors and windows on all floors below that are the same horizontal distance from the renovation work. DHS 163.14(11)(g)3.3. Ensure that doors within the work area that will be used while the job is being performed are covered with plastic sheeting or other impermeable material in a manner that allows workers to pass through while confining dust and debris to the work area. DHS 163.14(11)(g)4.4. Cover the ground with heavy duty plastic sheeting extending 10 feet beyond the perimeter of surfaces undergoing paint disturbance or a sufficient distance to collect falling paint debris, whichever is greater, unless the property line or neighboring structures prevent 10 feet of ground cover. Vertical containment or other precautions in containing the work area may be necessary in order to prevent contamination of other buildings, other areas of the property, or adjacent buildings or properties. Ground containment measures may stop at the edge of the vertical barrier when using a vertical containment system. DHS 163.14(11)(h)(h) Prohibited practices. All of the following work practices shall be prohibited or restricted during a renovation activity: DHS 163.14(11)(h)4.4.
