Final answer:
Ear protection is recommended for employees when noise levels reach 85 dB for an 8-hour daily exposure in order to minimize the risk of hearing damage. Option B is correct.
Step-by-step explanation:
When it comes to workplace noise levels and employee safety, there are specific guidelines. Nose protection should not be confused with ear protection, which is necessary to prevent hearing damage.
According to several government agencies and health-related professional associations, ear protection should be provided to employees when noise levels reach 85 dB for an 8-hour daily exposure. This recommendation helps to ensure that the risk of hearing loss is minimized in work environments with consistent noise.
The noise level at which nose protection should be provided for employees is 85 dB. Several government agencies and health-related professional associations recommend that 85 dB not be exceeded for 8-hour daily exposures in the absence of hearing protection.
