Floors mopping

Once the sterile work room has been constructed, follow a strict and unwavering regimen of hygiene. The room should be cleaned with a disinfectant, the floors mopped and lastly the room s air washed with a fine mist of 10% bleach solution. After spraying, the laboratory should not be reentered for a minimum of 15 minutes until the suspended particles have settled. A regimen of cleaning MUST precede every set of inoculations. As a rule, contamination is easier to prevent than to eliminate after it occurs. 

If a wet vacuum is to be used for pickup of detergent-germicide solution from the floor, the manufacturer s recommendations on filter life should be followed. In addition, the operation of the vacuum should be closely observed for evidence of operating changes such as restricted airflow or, conversely, increased flow indicating filter failure. Liquids collected in the vacuum cleaner after floor mopping will contain disinfectant material. These liquids may be poured down a convenient floor drain as local regulations permit, except for cleanup of wastes from an overt spill. These collected liquids should be autoclaved or treated with disinfectant solution before disposal. 

Decontaminate residual mercury. Any residual mercury must be chemically inactivated. There are two ways to accomplish this. A commercially available decontaminant, Hg-X (Acton Chemical Company, Newark, NJ), can be mixed with water and the floor mopped with the mixture. Hg-x acts by inactivating free elemental mercury. Another method utilizes elemental zinc powder, which is liberally sprinkled on the spill area. Then moisten the zinc with 5 to 10 percent sulfuric acid solution, enough to create a paste-like consistency. The paste is used to scour the contaminated surface and then is allowed to dry, whereupon the residue is swept up. The zinc forms an amalgam with the mercury this reaction is facilitated at a low pH. Sometimes these treatments cannot reach and react with all fugitive mercury, especially if some has run under the floor cov-... 

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. 

Floor poHshes typically are evaluated for gloss, appHcation and leveling properties, discoloration, sHp resistance, scratch resistance, heel-mark resistance, scuff resistance, damp-mopping and detergent resistance, repairabiHty, lack of sediment, and removabiHty (3). RecoatabiHty and formula stabiHty are also important. A review of test methods is available (35). More than 20 ASTM test methods for floor poHshes exist. From the standpoint of product safety, sHp resistance is a particularly important variable and many test methods are available (39). 

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. 

At the conclusion of the paving work at Corpus Christi, two electrolytic cells were cast of sulfur concrete for use in the zinc refinery. Subsequent to the work at Corpus Christi, a sulfur concrete floor was applied in the nickel plant at the Asarco Amarillo copper refinery. An isolating barrier of bitu-mastic material was mopped on the concrete before the sulfur concrete pour. This floor, a substantially smaller area, was overlaid on a damaged existing floor. Similar techniques to those described were used in mixing and placement.

Perchloric acid spilled on the floor or bench top represents a hazard. It should not be mopped up, nor dry combustibles used to soak up the acid. The spilled acid should first be neutralized and then soaked up with rags or paper towels. The contaminated rags and paper towels must be kept wet to prevent combustion upon drying. They should be placed in a plastic bag and sealed and then placed in a flammable waste disposal can. If the spill can be rinsed down a chemical drain, neutralization of the wetted area is recommended, followed by additional rinsing.16,30,31... 

Absolutely, and they are often the same people who don t want to learn about your situation. In general it can be said that people have a hard time putting themselves in another person s situation — especially one that does not exist in their own lives. If, for example, you don t get ill from mopping the floor, it s hard to imagine that someone else would. The conclusion very quickly will be made that it s just a ploy for attention. After all, judgment is usually passed fast ... 

Besides disinfection and stain removal, there are few other added benefits of major market importance. The next most important is the special class in which a polymer film is left behind on the surface. The most common example of this is not all-purpose cleaners, but are the mop and shine products for floor cleaning. This subset is intended solely for floor cleaning and leave behind a film intended to mimic the shine and soil resistance of waxing a floor. Unlike waxes, however, these polymer films do not need to be buffed to make them glossy [176], The only drawback to this kind of formula is the possible buildup of polymer on the surface. These polymer films tend to be slightly colored, and so repeated layers can yellow the surface. The aim of inventions in the field is therefore... 

Another benefit that also seems to have the benefit aimed at floor cleaning (because it may be about the only cleaning job still done with a bucket in developed markets) is the idea of coagulating the soil in the bottom of the bucket. This should mean that the wash water remains cleaner (if the mop is not put all the way to the bottom of the bucket) and soil removed from the floor is not redeposited. Although the patent art goes back to the late 1980s [178], only recently has a cleaner been marketed in the U.S. making exactly this claim. 

All-purpose dilutable cleaners are often used for floor cleaning. This results in a laborious task mixing of the solution in a bucket, washing of the floor with a mop (which must then be cleaned), rinsing of the cleaned surface (difficult on a large horizontal surface), and then cleaning the solution bucket in which the removed soil resides. 

In the dry system, dry nonwoven pads are supplied separately from the cleaning solution, which is bottled. The dry nonwoven is attached to the bottom of the pad on the mop, and the cleaning solution is fixed in some way to the mop, either in a holder for the bottle or in a reservoir. In the cleaning process, the consumer sprays the cleaning solution by activating a device on the mop and then wipes the mop over the wetted area [280], In either case, the consumer uses the wipe until no more soil can be picked up from the floor. 

Mor-Flo 430-M1 is a restorer concentrate formulation which can be easily diluted with water to form a "ready-to-use" solution. Recommended for mop-on applications where high and ultra-speed maintenance procedures are used. Since the restorer is a film former, floors should be clean and free of embedded soil prior to application. Application of the restorer fills small scratches and enhances gloss. The coating may be burnished after drying. 

The impermeable sheeting that was used must be misted and folded with the dirty side inward, and either taped shut or sealed in heavy-duty bags and disposed of. If the renovation was inside a building, then the renovator must clean all objects and surfaces. The walls must be cleaned with damp cloths or a HEPA vacuum, and all other surfaces and objects must be cleaned with a HEPA vacuum. All surfaces that are not carpeted or upholstered must be wiped with a damp cloth. All uncarpeted floors must be mopped and the rinse water must be kept separate from the wash water. At the end of the cleaning, a certified renovator must inspect to see if there is any dust debris or residue, and if there is the area must be re-cleaned and re-inspected.
