The Rail Safety Improvement Act of 2008 states that the Secretary of Transportation, by regulation, shall require each Class 1 railroad carrier to develop and update, at least once every 2 years, a fatigue management plan designed to reduce the fatigue experienced by safety-related railroad employees. The Act also requires a fatigue management plan to include “opportunities for identification, diagnosis, and treatment of any medical condition that may affect alertness or fatigue including sleep disorders”.
According to a 2004 Safety Advisory issued by the Federal Railroad Administration (FRA) untreated sleep disorders can result in impaired work performance such as loss of alertness and situational awareness. Therefore, the FRA recommends that employees’ medical examinations include assessments and screenings for possible sleep disorders and other associated medical conditions. While obstructive sleep apnea is considered one of the more debilitating sleep disorders and is a significant risk factor for on-the-job accidents, it is also one of the most easily diagnosed and treated of all sleep disorders.
