The purpose of this research To compare the performance of cyclone dust both before and after the
installation and the amount of dust in the work area and the amount of dust that enters the respiratory end. This research is an experimental study. Dust concentrations were measured to test the effectiveness of a dust cyclone laundry department. Conservation Thonburi Hospital Ubon Ratchathani province. The samples before and after the installation of dust cyclone 10 times the results were compared with the standard, according to NIOSH 0500 and 0600
from the trial showed that a 29 kg and 35 kg pre-installed with. intense dust in the work area, 3.92 and 7.04 mg / m3 and the concentration of dust into the respiratory system of the 2.82 and 4.23 mg / m3 after installation concentrations of dust in the work area, 1.43 and 1.84 mg / m3 and. the concentration of dust that enters the respiratory tract and distal 0 52 1.42 mg / m3, which is the result of the measurement criteria. Compared with the Ministry of the Interior Safety in the work on the environment (chemicals) for dust inhalation of 15 mg / m3 and the Threshold Limit Values 2014 (TLV 2014) for dust inhalation is 10 mg / m3 in the trap. dust of dust cyclones of dust in work fell by 27% and dust into the respiratory system of the lower 70%.
