Answer :
Final answer:
According to the OSHA, a worker can be exposed to 100 dbs of noise for 2 hours per day. Increased decibel levels decrease the allowable exposure time. The correct answer is 2-4 hours.
Explanation:
According to the Noise Regulation Guidelines set by the Occupational Safety and Health Administration (OSHA), an employee can be exposed to 100 decibels (dbs) of noise for 2 hours per day. This is because noise exposure is inversely proportional to duration, with increases in decibel level resulting in decreased allowable exposure time. Beyond this limit, prolonged exposure can lead to noise-induced hearing loss. Therefore, the correct answer to your question – 'How long can a welder be exposed to 100 dbs of noise per day?' – is b) 2-4 hours.
