Plastics sanitizing

P/astic. Plastic tubing is used for farm-to-receiving operations rather than for permanent food handling installations. It is widely used to transport water for cleaning and sanitizing. 

Every year, Americans use over one billion sharp objects to administer healthcare in their homes. These sharp objects include lancets, needles, and syringes. If not disposed of in puncture-resistant containers, they can injure sanitation workers. Sharp objects should be disposed of in hard plastic or metal containers with secure lids. The containers should be clearly marked and be puncture resistant. 

Plastic pipe or tubing may be used for a wide variety of services. As with all nonmetallic materials, code restrictions limit the applications in which their use is permitted. In general, their use in flammable or toxic service is limited. Plastic tubing of various types may be used for instrument air-signal connections however, as is the case with all nonmetallic applications, the need for fire resistance must be considered. When used)in specialized applications such as potable water or underground fire water, care should be taken to ensure that the specified products are certified by appropriate agencies such as the National Sanitation Foundation and Factory Mutual. 

Materials of Construction and Operational Stress. Before a centrifugal separation device is chosen, the corrosive characteristics of the liquid and solids as well as the cleaning and sanitizing solutions must be determined. A wide variety of materials may be used. Most centrifuges are austenitic stainless steels however, many are made of ordinary steel, mbber or plastic coated steel, Monel, Hastelloy, titanium, duplex stainless steel, and others. The solvents present and of course the temperature environment must be considered in elastomers and plastics, including composites.

Chemical manufacturing and petroleum refining have enriched our lives. Few individuals in the developed world stop to realize how the chemical industry has improved every minute of their day. The benefits of the industries are apparent from the time our plastic alarm clock tells us to wake up from a pleasant sleep on our polyester sheets and our polyurethane foam mattresses. As our feet touch the nylon carpet, we walk a few steps to turn on a phenolic light switch that allows electrical current to safely pass through polyvinyl chloride insulated wires. At the bathroom sink, we wash our face in chemically sanitized water using a chemically produced soap.

Chemicals are used, as drugs, to heal us when we are sick as plastics, they are employed in a range of products or their components which we take for granted as preservatives and sweeteners, they are added to our food we use them to clean and sanitize our kitchens and as antiseptics they are used to dye cloth and to brighten our lives, and we use them, as perfumes, to make us smell more appealing. In agriculture chemicals are used as fertilizers and pesticides to increase crop production and reduce starvation and to decrease disease borne by insects. They fuel our cars and aircraft, allowing us to travel. 

Few conclusive studies have identified the source or spread of Brettanomyces within the vineyard except for use of contaminated equipment. Contaminated and improperly sanitized crush equipment, drains, barrels, transfer hoses, valves, pumps, and bottling equipment can all act as sources for further infection (33). Harper (67) found the interior surface of plastic (polyvinyl chloride, polyethene, and plasticised nylon) pipes used commonly in the brewing industry maintained a variety of bacteria and yeast populations, including Brettanomyces.

Blow-fill technology is an aseptic process whereby the container is formed from thermoplastic granules, filled with sterile solution and sealed, all within one automatic operation. The bulk solution should have a low bioburden and is delivered to the machine through a filling system that has been previously sanitized and steam sterilized in situ. Concern has been expressed that the machine itself may generate particles. The plastic granules are composed usually of polyethylene, polypropylene or one of their copolymers and are heat extruded at 200°C into a tube. The two halves of a mould close around this tube and seal the base. The required quantity of sterile fluid is filled into the container, which is then sealed. Products packed in this way include intravenous solutions, and small volume parenteral, ophthalmic and nebulizer solutions. The...

Additives produced by Sanitized for the protection of plastics against microbial attack are reviewed, with particular reference to the EPL 91-35 antimicrobial agent for PVC products. The advantages of using this additive in PVC floor coverings are examined. 

Another commonly used approach to purified water generation, storage and distribution is RO/DI. Figure 4 is a schematic of an RO/DI approach. The components in this type of system are usually all plastic, therefore, sanitization is done chemically. Use of a sterilizing 0.2 micron filter in addition to, or instead of, the resin filter should be resisted. This practice may appear beneficial, but it is specifically prohibited by the proposed LW GMP s (proposed CFR 212.49) and it is not recommended.
