Floor drying

One-step clean-and-shine products have become popular in the household market. These products are appHed to the floor with a sponge mop and their detergent action removes and suspends soil, which coUects on the mop and is removed when the mop is rinsed with water. The formulation, which remains on the floor, dries to a poHsh film. An earlier product of this type was dispensed from an aerosol as a foam. Formulas as of this writing (ca 1995) are appHed as Hquids (29,30). In one product, the dried film obtained from the formulation is soluble in the formulation, which includes low molecular weight, high acid polymers and a fairly large amount of ammonia (31). Repeated use does not contribute to a buildup of poHsh. 

The most common spill on a laboratory floor is water, not generally considered hazardous. It may, however, create hazardous conditions by making the floor slippery. It is dangerous to walk on a wet floor with certain types of soles. A wet area should always be blocked off until it is dry. Mop and bucket should always be available close by, not in a janitor s closet down the hall. String mops are superior to sponge mops for getting the floor dry. 

In the study by Elmholt (2003), results from three consecutive years at two farms with slow drying systems (on-floor and in-bin) were very consistent and it was concluded that these drying facilities were insufficient and conducive to growth of P. verrucosum. Further examples of on-floor drying being conducive to P. verrucosum were given by Elmholt and Rasmussen (2005).

The need for floor drains should be considered, as well as the ability to collect wastewater for treatment or incineration. If floor drains are installed, the floors should slope toward the drain from all directions. Drain cover materials should also be evaluated with regard to quality, ease of sanitation, and cleaning. Fig. 4 shows a multipurpose room with an easily cleaned floor, dry-wall fiberglass mat with epoxy-painted walls, floor drain, and utility panel. This room also has self-contained hot- and cold-water wash-down capability.

All spillages must be cleared up, and wet floors dried, immediately. 

A drip pan (also called a drain board) is one of the simplest methods for dragout recovery. The drip pan is located either under the rack while in transit or between tanks, and will capture drips of process solution from racks and panels as these are transferred between tanks. Drip pans not only save chemicals and reduce rinse water requirements, they also improve housekeeping by keeping the floor dry.
