[Use of rooms with laminar air flow]. / Ispol'zovanie boksov s laminarynym potokom vozdurha

The paper deals with the problem of dependency of the reduction of microbial contamination and of dust pollution of the air mediu min the CAMERA-BOXES with a liminary flux on the aeration degree. It was shown that the degree of aeration in the camera-box constituted from 330 to 1060, with the rate of the air flux at the filter exit of from 0.2 to 0.6 m/sec. Vertical laminar flux provided release of the air from the microbes and dust. The use of the camera-box with a laminar flux for work requiring sterile conditions is recommended.

[The use of the 2600H high-pressure paint-sprayer for killing insects]. / Primenie okrasochnogo agregata vysokogo davleniia 2600H v tseliakh dezinsektsii.

Physical and mechanical parameters of the paint-sprayer 2600H were studied under laboratory conditions. Studies of the feasibility of using this device for desinsection were performed under real conditions in moderate--and hot-climate areas. High efficiency of POC and pyrethroids spraying for home mosquito and fly control was demonstrated. High pressure paint-sprayer treatment ensured a longer residual effect than "Automax". The use of the sprayer for desinsection may save time and labour.

[Tactics in using aerosols for disinfection of therapeutic and prophylactic institutions]. / Taktika primeneniia aérozolei dlia tselei dezinfektsii pomeshchenii lechebno-profilakticheskikh uchrezhdenii.

Two Soviet sprayers (ABD-2600H and EOC-5) are recommended for the disinfection of the surfaces and indoor air in the curative and prophylactic facilities. A special impetus has been given to the use of chloramine aerosols that ensure higher efficacy of disinfection, reduce the aerosol consumption and the period of the presence of active chlorine in the air of the treated place.
