To ensure the protection of frontline healthcare and emergency medical workers at high risk of infection with H1N1 virus, the Occupational Safety and Health Administration says it will soon issue a compliance directive to ensure uniform procedures when conducting inspections to identify, minimize or eliminate risky occupational exposures to the H1N1 (swine flu) virus.

OSHA says the directive will closely follow the Centers for Disease Control interim guidance for controlling the virus in healthcare settings and protecting healthcare workers.

In response to complaints, OSHA says its inspectors will ensure that healthcare employers implement a hierarchy of controls, including source control, engineering, and administrative measures, encourage vaccination and other work practices recommended by the CDC. Where respirators are required to be used, the OSHA Respiratory Protection standard must be followed, including worker training and fit testing, the agency says.

The CDC recommends the use of respiratory protection that is at least as protective as a fit tested disposable N95 respirator for healthcare personnel who are in close contact (within 6 feet) with patients with suspected or confirmed 2009 H1N1 influenza. Since a shortage of disposable N95 respirators is possible, employers are advised to monitor their supply, and prioritize their use of the respirators according to guidance provided by CDC.

OSHA says where inspectors determine that a facility has not violated any OSHA requirements but that additional measures could enhance the protection of employees, it may provide the employer with a Hazard Alert Letter outlining suggested measures to further protect workers.
