Situation:
Noise at Work Ediberto is 18 years old, and has been working for a
company that manufactures prefabricated homes for about a year. He spends a
lot of the work day using a power saw. His ears usually ring for a while in
the evening, but it seems to clear up by the morning. He is a little worried
about whether it’s damaging his hearing, but it’s not that different than how
his ears feel after a rock concert. He wants to find some information on how
much noise is bad for you, and what he can do.
Questions for following story.
1. What went right in this situation?
2. What went wrong in this situation?
3. What steps should be taken in this workplace to make sure employees are
better protected and prepared the next time?
