Wipe down

Wherever practicable it is advisable for glutaraldehyde to be replaced by a less hazardous chemical, e.g. it should not be used as a general wipe-down disinfectant. 

Cleaning should be carried out with relative ease and with the use of standard cleaning materials [7]. Vacuum facilities should be available for cleaning and contact parts fouls be wiped down and sanitized utilizing a sanitizing agent. The equipment should be washed, dried, covered, and stored in an equipment storage area. 

The same factors also apply to sanitizing agents used to wipe down cleaned equipment. For example, it is a quite common practice to wipe down equipment used to manufacture nonsterile pharmaceuticals with isopropyl alcohol (IPA) subsequent to cleaning the equipment. This final IPA wipedown can be a source of contamination if the IPA is not subsequently removed. Although IPA is fairly volatile, it can pool in the intricate surfaces of a closed...

After sampling and harvesting the Luer-Locks must be wiped down with 70% ethanol to prevent infection being introduced to the production module see Note 20). Periodical measurement of cell density, viability, and antibody production during the course of the production run will help in the planning of future production runs. 

If it is not possible to weigh directly into a sealable vessel within the weighing hood, then the powder should be transferred into a suitable sealable container prior to removal from the weighing hood. The use of a powder funnel will ensure that the compound is appropriately transferred. A surface wipe-down of any vessel leaving the enclosure should be done. 

Clean-facility construction materials should be left in an outer shipping wrap until moved to the temporary lay-down area, where they should then be unwrapped and wiped down before being moved into the clean space. 

All ductwork sections should be cleaned and sealed with plastic wrap at the time of fabrication until just prior to installation or start-up to prevent contaminants from accumulating inside air-handling passageways. The sections of ductwork should be unsealed only as required for installation. Open ends of ducts and fans should remain sealed until connecting duct is about to be installed. A final isopropyl alcohol (IPA) wipe-down of all interior duct sections and fan surfaces should be done immediately prior to installation. 

Successful completion of the cleaning process described above will indicate that installation of process equipment may begin. Note that procedures described in Appendix A should be followed. After installation of all process equipment or when the clean room is to be prepared for certification, steps 2K-20 of Appendix B for final wipe-down can be followed. 

C. All tools, parts, and equipment will be properly cleaned prior to entering the clean room. Minimum cleaning should be a total wipe-down with isopropyl alcohol, using certified clean-room wipes, to assure that the last wipe does not leave visible residue on the wipe. Parts should be blown off outside the clean room using filtered nitrogen when available. 

D. All parts and equipment should be sent through the equipment wipe-down area (material air lock) and not carried through the gowning area. 

Wipe-down of the HEPA filter grid, all lights, walls, floors, windows, and all exposed interior surfaces. This will include any outlet boxes or floor/ wall recesses. 

Wipe-down should be by clean potable water and mild nonphosphate detergent using clean, lint-free cloths approved by the clean-room monitor. 

K. Commence with the first of two final wipe-downs. Nonshedding clean-room wipes (saturated with isopropyl alcohol) or tacky wipes should be used. All exposed surfaces should be wiped. 

N. If the search for filter leakage fails to find a leak, the entire area should be recleaned as described for the final wipe-down. 

After final sanding, the stock is wiped down with alcohol and painted with black enamel primer. All small holes should first be filled In with plastic wood putty or body putty. Do not paint the Stock tubes or the stock will not be able to s1 de freely. It can be blackened with touch up blue or with one of the formulas on page t1, issue II. The stock tubes should have a light coat of oil to Insure smooth operation. 

Read the manual before you first open up the fuel cell unit and start poking around. There may be special instructions for accessing certain parts of the unit. Also note if the unit is dirty or not. If it is, vacuum and wipe down the unit as well as possible. Many units have air ducts, filters and fan blades that should be inspected and cleaned on a regular basis. 

Materials that cannot be sterilized should be transferred into the sterile area through an isolated area in which an outer wrapping is removed. The object is then wiped down with a sanitizing agent such as isopropanol or hydrogen peroxide. 

Stationary equipment such as conveyors and filling equipment must be sanitized at some specified frequency. This can be accomplished by wiping down with a sanitizing agent or fogging the sterile area with formaldehyde. All product contact parts such as powder hoppers, filling wheels, and stopper bowls are removed from the sterile area, cleaned and sterilized as previously described.

Because microorganisms are airborne, laboratory surfaces should be sterilized prior to beginning work. To do this, there are many aerosol disinfectants available that are simply sprayed onto the area and wiped away. Some laboratories rely on solutions of chlorine (bleach) to assist in maintaining a sterile environment. Although ultraviolet light can be used as a surface sterilant, most laboratories rely on wiping down the area with a liquid disinfectant (Table 13.3). Several disinfectants that find application in the winery (Chapter 9) can also be used in a laboratory such as iodine or QUATS. Other laboratory disinfectants are the phenol-based formulations like o-phenylphenol (Lysol ) and hexachlorophene (PhisoHex ).
