Question

As per the DGMS norms, warning level of noise for the worksite area is

• A. 85 dBA
• B. 90 dBA
• C. 95 dBA
• D. 100 dBA

Hint:

Regular noise monitoring and providing hearing protection are essential to comply with DGMS norms and ensure worker safety in noisy mining environments.

Answer 1

The Correct Option is A

The Directorate General of Mines Safety (DGMS) in India sets guidelines for noise levels in mining worksites to protect workers from noise-induced hearing loss. According to DGMS norms, the warning level for noise exposure in a worksite area is 85 dBA. This is the threshold at which precautions, such as hearing protection, must be implemented to prevent long-term hearing damage. Levels above 90 dBA are considered the permissible exposure limit for an 8-hour shift, but 85 dBA is the warning level where action must be taken.
Thus, the correct answer is 85 dBA.
