1. General Information
1.1. Polyethylene drums (hereinafter referred to as drums) are produced by the extrusion technique according to technical specification (TS) of high-molecular HDPE (high density polyethylene) which accords with GOST 16338 or of polyethylene of foreign manufacture with similar physicochemical properties allowed for contact with food spheres by the agencies of the State Sanitary Epidemiological Surveillance Department of the Russian Federation; lids are produced of polypropylene “BALEN” and HDPE 276; bungs –of propylene 22015 and caps - by molding. Drums are certified and approved to usage as a packaging for prepacking, transportation and storage of petrochemical and food products (such as vegetable oils and eatable fats, milk and milk products). Drums meet the requirements of hygienic norms 2.3.3.972-00 “Prohibitive amounts of chemical agents evolved out of materials that contact with food products”.
Drums are completed with rubber o-ring gaskets, clamping rings made of galvanized steel, screwed bungs, sealing rings for bungs and safety caps.
1.2. During drums’ sanitation it is necessary to operate in accordance with the requirements of SanPiN 2.3.4.551-96 (sanitary regulations and standards) “Sanitation manual of equipment, gears and packing materials at the milk industry”.
1.3. For drums’ sanitation it is allowed to use only detergents and disinfectants that are approved by the State Sanitary Epidemiological Surveillance Department of the Russian Federation for usage in milk industry. The disinfectants application instructions at the milk industry plants should be confirmed by the State Sanitary Epidemiological Surveillance Department of the Russian Federation and State Institution “All-Russian research institute of milk industry”, and concerted by the Federal Commission on disinfectants.
1.4. Drums’ sanitation can be done by specially appointed staff: cleaners, washers and equipment operators. They are to be older than 18, have no medical contraindications for such job or allergic diseases, they should be instructed for safety working with detergents and disinfectants and trained to execute first-aid in case of accidental poisoning.
1.5. Personnel dealing with drums’ sanitation should wear special protecting clothes(cotton suit or coverall, canvas apron) and protection means for eyes – hermetic glasses (GOST 12-4-013-75), for body - coverall (GOST 1549-69 or 6011-69), for feet - rubber boots (GOST 5375-70), for hands skin - rubber gloves (GOST 20010). It is necessary to use only intact and clean inventory meant for drums sanitation (wire brush, broom, scoop and measuring containers).
1.6. Detergent and disinfectant fluids should be prepared in isolated, well-aired equipped with combined extract and input ventilation. It is necessary to put up manuals for preparation of detergent and disinfectant fluids, rules of washing and disinfection, manuals and posters on safe operation of washing equipment and to place first-aid set in the detergent and disinfectant preparation department (appendix 1).
1.7. Detergents and disinfectants should be stored separately from food products in hermetic packaging in a dry, well-aired covered room and be kept away from children.
1.8. Drums sanitation requires tables and shelf stands for drying of lids, clamping rings, bungs and gaskets.
1.9. Control of sanitation system regimes (temperature and concentration of detergent and disinfectant fluids) is carried out in accordance with “Instruction on technical inspection at the milk industry plants”, “ The sanitation manual of equipment, gears and packing materials at the milk industry” and usage manuals of certain detergents and disinfectants. Concentration of detergents and disinfectants in work fluids should be controlled at least one time a day before using.
1.10. It is necessary to control completeness of drums’ and lids’ rinsing out off detergent and disinfectant fluid residuals in accordance with appendix 2.
1.11. Worked out alkaline detergent and disinfectant fluids are used for sanitation of surfaces of workplace (walls, floor).
1.12. Drums that are not used for more than 6 hours after washing and disinfection should be disinfected one more time and rinsed off disinfectant residuals by clean water before using.
1.13. Microbiological quality control of sanitation is carried out in accordance with “Instructions for Microbiological control of production process at the dairy plants”.

3. Polyethylene drums sanitation
3.1. Washing of drums, lids, clamping rings and bungs is carried out after every discharging. Drums and lids disinfection is carried out before every usage. In some extraordinary cases it is allowed to keep fully water filled drums covered with lids before they will be cleaned.
3.2. Before drums’ sanitation it is necessary to control visually cleanness and safety of drums and lids (they should be without splits, dimples, cavities and chips) as well as to check them for presence of some foreign objects (no foreign objects are to be inside them).
3.3. It is necessary to use tap water (it should meet the requirements of SanPiN 2.1.4.559-96 “Potable water” and GOST 2874-82 “Potable water. Hygienic requirements and quality control surveillance“) for preparation of detergent and disinfectant fluids as well as for rinsing off.
3.4. For sanitation of big quantities of drums and lids it is reasonable to use two- or three-section washing baths equipped with fitting for draining of fluids.
3.5. Order of washing and disinfection of drums and lids: - fully fill drums with warm tap water (20-35 ºС) put lids, clamping rings and bungs into washing bath section for 5-7 minutes;
- drain water from drums or bath sections;
- wash out drums, lids, clamping rings and bungs with the warm running tap water using a hose, wipe several times* all surfaces using brooms and wire brushes to clean out of product residuals, pay special attention to cuts/grooves for closing, clamping rings and reinforcement ribs;
- fill drums in with 4-5l of work alkaline detergent fluid and wash out surfaces with the help of brooms and wire brushes for 3-5 minutes at fluid temperature of 35-50ºС or prepare work detergent fluid in the section of portable washing bath so, that drums are filled in on one-third of their volume and wash their surfaces in a half-dipped state by wiping them several times using brooms and wire brushes, pay special attention to treatment of cuts/grooves for closing, and reinforcement ribs **;
- wash drum lids, clamping rings and bungs off in alkaline work fluid prepared in the section of portable washing bath by dipping them into fluid and frequent wiping with the help of brooms and wire brushes;
- drain washing fluid off drums and washing bath section;
- rinse off drum lids, clamping rings and bungs off with clean tap water using a hose till neutral reaction (appendix 2);
- fill drums in with 3-5l of work disinfectant fluid and wash them by frequent wiping of all surfaces using brooms and wire brushes or disinfect them by fractional dipping in the washing bath section with disinfectant fluid with wiping of all surfaces using brooms and wire brushes***;
- disinfect drum lids, clamping rings and bungs by dipping them into work disinfectant fluid prepared in washing bath section, wipe them several time with the help of brooms and wire brushes;
- drain used washing fluid out off drums and washing bath section;
- rinse drums, lids, clamping rings and bungs off disinfectant residuals with the warm running tap water in accordance with the manual of this disinfectant;
- place clean turned drums, lids, clamping rings and bungs on special disinfected and washed by alkaline fluid shelf stands.
* Notes:
*Hand method of sanitation means frequent (not less than 15 times per minute) wiping with the help of brooms and wire brushes accompanied with frequent applications (not less than 10 times a minute) of work fluid to the treated surface, that provides equal wetting of surface and continual existence of detergents and disinfectants on it.
**During usage of alkaline agents with detergent and disinfectant effect “MD-1” or similar agents (“Katryl-D”, “MSTA”, “NIKA-2” etc.) carrying out cycle of disinfection is excluded, but time of washing with such agents increases to 10-15 minutes.
***The regimes of disinfection (concentration, temperature, exposition) are described in usage manual of every allowed disinfectant. Protein-fatty contamination of the disinfected surfaces are unacceptable.

Appendix №2
1. Control of residual alkalinity.
Presence or absence of residual alkalinity on the treated surfaces tests with the help of universal indicator paper for identification of рН in intervals from 0 to 12.
It is needed to apply indicator paper and press it down to the wet surface of a treated object straight after washing and rinsing off. Indicator paper coloration in blue color of varying intensity speaks for presence of residual alkalinity on the controlled surface. Paper looks the same and its color stays yellow - there is no residual alkalinity.
During control of residual alkalinity in wash water it is needed to fill test-tube in with 10-15 cm³ of water and then to add in it 2-3 drops of 1% phenolphthalein fluid. Color changing of wash water into crimson speaks for presence of alkali, water stays colorless – there is no alkali in it.
2. Control of rinsing completeness of QAC residuals.
It is recommended to use special indicator paper (like “QAC QR TEST Strips” made by “LaMotte Company”, USA) for qualitative identification quaternary ammonium compound (QAC) concentration on the surfaces of equipment and in wash water. Recommended indicator paper enables to identify concentrations of QAC from 0 to 500 mg/l.
Rinsing completeness of QAC residuals from the surface of disinfected object is determined by application of indicator paper to the wet surface and in wash water – by dipping.
If after 90 seconds the colour of indicator paper stays the same/not changed it testifies that QAC residuals are fully washed out. In case of QAC residuals presence in wash water or on the surfaces indicator paper’s color becomes yellow-green or dark green or khaki color of various intensity.
