Which statement best reflects guidelines for pregnant workers regarding noise exposure?

• A. Impulse noise is encouraged if hearing protection is worn
• B. Job rotation for pregnant workers of 20 weeks exposed to hazardous noise should be considered; avoid impulse or impact noise environments requiring hearing protection
• C. There are no special guidelines
• D. Hearing protection is never required

Answer: (B)

Noise exposure during pregnancy is managed by reducing how long and how intensely a worker is exposed, with a special emphasis on avoiding the most harmful noise types. When a pregnant worker around mid-pregnancy is exposed to hazardous noise, shifting them to a different, quieter assignment limits the overall noise dose they receive. In addition, impulse or impact noises deliver sharp, high peak pressures that can be more damaging, so avoiding environments with those noises while pregnant helps protect both mother and fetus. Hearing protection remains important in noisy settings, but the best approach here is to minimize exposure by job rotation and by steering away from loud, impulse-heavy environments rather than relying solely on protection. The other statements don’t align with this approach, as they either downplay pregnancy-specific safeguards or imply protection alone is sufficient.
