Darbo aplinkos tyrimas karvių melžimo aikštelėse

The aims of the research are to analize environment in the milking platform and rate damaging factor for environment of the work. The research was carried on ASU educational economy cowshed, Tandem type milking platform, where 142 cows are milked on every milking process. The air temperature of milking platform in autumn match the norm - 17 ± 0,2 oC, on winter period is lower than allowed - 15,5 ± 0,3 oC, when the allowed temperature is 17-25 oC. Humidity in autumn – 71 ± 0,7 % and winter – 73 ± 0,7 % both do not match the optimal norm (40-60 %), but is not above the highest mark which is 75 %. During research of gas consentration on workplace, it was find out that the highest gas consentration is at the end of the process, when it is finished to milk all the cows, but the highest allowed gas concentration was not above the mark. When the noise in the workplace was measured it was find out that the highest level of average equivalent sound pressure while milking the cows in autumn was about 59.2 ± 3,7 dB, and in winter time – 58.9 ± 4,6 dB, that is not above the highest mark which is 85 dBVytauto Didžiojo universitetasŽemės ūkio akademij
