For propane-powered floor equipment, what is the maximum sound level allowed according to ISO 11201?

80 dBA
85 dBA
90 dBA
95 dBA

The correct answer is: 90 dBA

The maximum sound level allowed for propane-powered floor equipment according to ISO 11201 is indeed set at 90 dBA. ISO 11201 is a standard that specifies measurement methods for the determination of sound emitted by machinery and equipment. Setting a maximum sound level helps minimize noise pollution in work environments, contributing to better acoustics and overall worker comfort. The regulation emphasizes the importance of managing noise levels, particularly in indoor spaces where floor equipment is commonly used, as excessive noise can adversely affect staff productivity and health. Adhering to these standards helps organizations create a safer and more pleasant working environment. The other sound level options provided do not align with the specified limits in ISO 11201 for propane-powered floor equipment, which is critical for maintaining sound at levels that are manageable and safe for continuous exposure in workplace settings. The choice of 90 dBA reflects an effort to balance operational needs with environmental and safety considerations.
