The National Institute for Occupational Safety and Health (NIOSH) and the American Conference of Governmental Industrial Hygienists (ACGIH) recommend using an exposure limit of 85 dBA instead of 90 dBA and also recommend using a 3 dB exchange rate. These levels are much more protective than the levels currently used by OSHA.

1.Discuss the merits of each of the two methods. Provide your opinion as to which of the approaches you believe should be used. Support your answer with at least one professional/scholarly reference.

2. OSHA does not currently have a regulation specifically covering ergonomic issues. OSHA has issued several guidelines for some specific industries. Consider a workplace you are familiar with where there is a potential for repetitive motion injuries.

Discuss what methods you would use to identify tasks that would present the greatest risk for repetitive motion injuries. How would you establish an ergonomics program to address the issues? What would be the greatest obstacles in establishing the ergonomics program?
