METHODICAL INSTRUCTIONS

 

on use of chloric lime for disinfection

 

1. GENERAL  INFORMATION



  1. Chloric lime - the powdery product of white color of alkaline reaction having a chlorine smell, mix of various salts of calcium. Quality of chloric lime is defined by content in it active chlorine (chlorine which is forced out at action on chloric lime of acids). Chloric lime contains 35—32-26 of % of active chlorine. At dissolution in water forms a suspension. The deposit consists of insoluble salts of Sasozi Sa (IT) 2.

 

  1. Chloric lime possesses the strong oxidizing action  in this connection decrease in durability of fabrics  and corrosion of metal wares are possible.

 

  1. Chloric  lime - the unstable chemical compound which is quickly decaying under the influence of   carbonic acid,   moisture, light,  high temperature. Even  at  the correct  storage of chloric lime (in dense a wooden pla to the iron container protected from corrosion in the dry cool room)  loss of active chlorine makes 1 — 3% a month.    In this regard it is necessary systematically    (at least 1 time in 3 months)  to investigate chloric lime on the content of active chlorine. The lime released by the industry belilny, heat-resistant - the stable product and at the correct storage, according to TU 6-01-589-71.potern of active chlorine within 8 years is not exceeded by 7 — 9%.

 

  1. Storage of chloric lime is allowed only in standard packing in the closed, darkened and well ventilated warehouse inaccessible for rainfall.
    Floors of warehouse for storage of chloric lime are recommended to be made of asphalt, a brick and clay.
    Use of iron as material for designs of a roof or a roof is not allowed.
    Storage in one room with chloric lime of explosives, flammable products, lubricant oils, foodstuff, metal products and cylinders with the compressed gases is not allowed.
    At storage laying of a secondary container with chloric lime on height six-row, on width two-row is allowed.
    The distance of a stack of chloric lime from heating units has to be not less than 1,5 m.
    Temperature of chloric lime in the plastic bags which are in the center of a stack should not exceed 40 °C.

 

  1. Chloric lime possesses high   activity concerning vegetative and sporous forms    of microorganisms.
    Chloric lime is applied for disinfection at intestinal, drop and other infections; tuberculosis, anthrax in the form of the clarified solutions (usual and activated), hlornoizvestkovy milk and in a dry form.



II.PRIGOTOVLENIE OF SOLUTIONS OF CHLORIC LIME



  1. The clarified 10 — 20%  prepare solutions of chloric lime as follows:  1-2 kg pound with addition of a small amount of water to a condition of uniform gruel. Then add other amount of water (to 10 l) mix before formation of a uniform suspension and leave for upholding in the glass dark or   enameled ware with a stopper for 24 hours.   After that the clarified solution is carefully merged or filtered in other similar ware.



       From the clarified solution of chloric lime of 10 - 20% of concentration prepared main just before disinfection prepare working solutions of the necessary concentration, being guided by the following table No. 1

 

                                                                                                                         Table 1.

III.NORMY RASHODA OF CHLORIC LIME.



  1. Consumption rates of chloric lime define according to the application purpose, and also depending on firmness of causative agents of infections, quantity and character of organic substances of the disinfected environment. For disinfecting it is superficial at intestinal and drop infections of a bacterial etiology solutions use at the rate of 300 ml/sq.m. For disinfecting at anthrax, natural smallpox and tuberculosis the consumption rate is increased to 500 — 900 ml/sq.m. The consumption of dry chloric lime for disinfecting of allocations is specified in item 15.



IV. USE OF CHLORIC LIME

 

Use of the clarified solutions of chloric lime



  1. The clarified solutions of chloric  lime    apply to disinfection of the room, furnishings, ware, harvest stock. Disinfecting is carried out by an irrigation,  wiping, soaking.   The linen and other   fabrics, and also metal objects   if they are not protected from corrosion,  are not subject to disinfecting by solutions of chloric lime even of weak concentration.
    For disinfecting of the room and furnishings at intestinal and drop infections of a bacterial and virus etiology Solutions of chloric lime use from 0,05 to 0,5 — 1 — 3%. Invaluable things (rags, harvest material , etc.) presoak in 0,2 - 3% solution.
              Ware without the remains of food immerse, in 0,05% the clarified solution of chloric lime, and with the food remains — in 1 — 3%. For disinfection of night ware after removal of its contents solutions use 0,5 — 1%.
                  The clarified solutions of chloric lime apply 10-20% to disinfecting at tuberculosis and anthrax.



Use of the activated clarified solutions of chloric lime.



  1.           Apply the activated solutions of chloric lime to group of infections which causative agents possess big firmness (tuberculosis, anthrax, viral hepatitis, enteroviral infections, natural smallpox)  under following conditions:
              a) at tuberculosis (nonmetallic) after removal of the food remains in the mechanical way apply 2% to disinfection of ware the activated solution at an exposition (30 minutes)
             b) at anthrax for disinfecting brick and the surfaces which are stuck together by wall-paper — 4% the activated clarified solution of chloric lime at a 2-fold irrigation with an interval 30 minutes.
              c) at  viral  hepatitis, enteroviral infections and natural smallpox for disinfecting of ware from under allocations,  tableware      of food, (nonmetallic) after removal of the remains, apply 0,5 — 1%  the solution of chloric lime activated osvetlen1ny at an exposition of 60 — 30 minutes respectively.



Use of chlorine-limy milk



  1. Chlorine-limy  milk  is applied    to  rough disinfection, to disinfecting  of allocations    of the infectious patients and also objects infected   with causative agents of anthrax,  which are not spoiling from chloric lime  (the soil, laying and a forage of animals and so on).

 

  1.       i20% of concentration apply chlorine-limy milk 10:
    a) for whitewashing of walls at all types of an infection: once at group of intestinal and drop infections, fungal diseases and twice at tuberculosis;               b) for disinfecting of wooden   parts   of domestic bathrooms at intestinal infections;
    c) for a .obezzarazhivaniye of wooden parts of non-residential premises;
    d) for disinfecting of freight cars after transportation of animal or any infectious materials;
    e) at anthrax for disinfecting   of almost all types of surfaces by whitewashing of 40%  chlorine-limy milk at the 24th hour exposition at   a temperature of 18 ° and a 48-hour exposition — at a temperature not below 10 ° (wooden surfaces bleach two times).



Use of dry chloric lime.



  1. For disinfecting of fecal mass of patients and carriers of infections, intestinal  group,   and also a phlegm of tubercular patients use chloric lime  in a dry form.
    Dry chloric lime is applied to disinfecting:
               a) wet — in number of 1 g/l within 60 minutes.
               b) for disinfection of the issued fecal masses (in night ware, the vessel)  or mixes   a calla with the urine   containing issued by kcal for disinfection of emetic masses - 200 g of chloric lime on 1 liter of weight, validity period 1 hour. Dense kcal before addition of dry chloric lime stir with a half amount of water.

 

  1. Dry chloric lime is applied to disinfection of the phlegm collected from tubercular patients at depletion of spittoons. In this case spend 200 g of chloric lime for 1 l of a phlegm, validity period 1 hour. When disinfecting a phlegm in spittoons spend 12 g of chloric lime on condition of filling with their phlegm to a mark not higher than 60 ml.



 V. Measures of personal precaution during the work with chloric lime.

 

During the work with chloric lime measures have to be taken for protection of respiratory organs, sight and integuments (RU-60 respirator, rubber gloves, goggles, an apron from the rubberized fabric).
