Final answer:
The information provided does not support the statement that a safety monitor must meet the specific age and voice range requirements listed. The detail about 85 decibels relates to the maximum safe exposure for noise in an 8-hour period, not qualifications for a safety monitor.
Step-by-step explanation:
The statement that a safety monitor must be at least 25 years old and have a voice range that can reach 85 decibels is not supported by the provided information. The requirement for the age of a safety monitor is not mentioned in any of the information supplied, and the voice range specified has to do with safety limits for sound exposure, not the abilities of a safety monitor.
According to several government agencies and health-related professional associations, 85 decibels (dB) is the recommended limit for an 8-hour daily exposure to noise without hearing protection. Exceeding this can lead to hearing damage over time. This recommendation is meant as a safety guideline, not as a qualification for becoming a safety monitor.
It's important to note that having a voice that can reach up to 85 dB could be useful to warn people in a noisy environment, but it is not a requirement mentioned in the information. Additionally, long-term exposure to noise levels above 85 dB without proper hearing protection can increase the risk of noise-induced hearing loss.
