Red Seal Welding Practice Exam

What is the maximum noise level workers should be exposed to?

1. 85 dB

2. 90 dB

3. 95 dB

4. 100 dB

The correct answer is: 90 dB

The maximum noise level workers should be exposed to is 90 dB. This is because prolonged exposure to noise levels above 90 dB can cause permanent hearing damage. Option A is incorrect because 85 dB is the recommended maximum noise level for an eight-hour day. Option C and D are incorrect because they exceed the recommended maximum noise level and can cause immediate damage to the ear. It is important for workers to follow safety regulations and protect their hearing by staying below 90 dB.
