It is not possible to judge whether the noise is qualified only on the basis of "the maximum speed of the rotating cup is 60,000 rpm" or "the maximum air pressure used by the spray gun". Occupational health compliance evaluations target workers' exposure to noise in actual jobs, rather than the equipment parameters themselves. After clarifying the equipment model, operating load, spray room fan, exhaust system, air compressor, paint supply system, multi-gun simultaneous operation state, worker position and contact time, A-weighted equivalent sound level or personal noise dose must be obtained according to the occupational health noise measurement method, and then compared with the applicable limit value.
