The high utilizing of thermal fogger machine in agriculture is giving an impact for operator’s health and comfortness. This is because of mechanical vibration and noise level which produced by thermal fogger machine disturbing operator activity. Measuring of vibration and noise on thermal fogger machine was conducted by using vibrationmeter and sound level meter. The measurement results show that the operator was exposed 99.4 dB(A) noise and 4.03 m/s vibration. A hand arm vibration nomogram was employed with vibration factor 3 hours for comfortable level and 8 hours for safety level, concurently with noise standard provided by National Ministry of Labor. The result derived from noise analysis shows that daily exsposure time of the machne utilization is 15 – 30 minutes as the noise factor shows significant effect on the machine operation. As the preventing action to decreasing noise level, it can using ear muff and ear plug. Beside that, by covering the machine using foam rubber.
