Plastic can be a slip hazard in some jobs, such as handling granite counter tops. This creates a more immediate safety concern than protecting the floor from dust. Can't I just clean the floor at the end of the job?
No. For interior renovations, before beginning the renovation the renovation firm must cover the floor surface, including installed carpet, with taped-down plastic sheeting or other impermeable material in the work area 6 feet beyond the perimeter of surfaces undergoing renovation or a sufficient distance to contain the dust, whichever is greater.
You must comply with this requirement unless it is impossible to do so, for example, during portions of a renovation project that involve removing flooring, sanding a hardwood floor, or removing or installing carpeting. However, the RRP Rule allows you to place another, less slick, disposable surface (such as paper) on top of the plastic sheeting as long as the plastic sheeting remains intact. Remove and dispose of both surfaces at the completion of the job.
Even when plastic is used to cover the floor, you must also clean the floor at the end of the job. Thoroughly vacuum using a HEPA vacuum. The HEPA vacuum must be equipped with a beater bar when vacuuming carpets and rugs. Mop uncarpeted floors thoroughly, using a mopping method that keeps the wash water separate from the rinse water, such as the 2-bucket mopping method, or using a wet mopping system.
