Indiana has no specific law or regulation requiring employers to conduct fire drills. However, Indiana's own state health and safety code has adopted the safety standards of the federal Occupational Safety and Health Act (OSH Act). The OSH Act, applicable to the private sector workplace, requires that companies with 10 or more employees have written fire prevention and emergency exit plans for each workplace. Employers with fewer than 10 employees may communicate the plans orally. To ensure that the exit plan will work in an actual emergency, it is advisable to rehearse regularly with annual or semiannual drills.
Indiana does require that schools conduct at least one tornado drill and one man-made occurrence drill per semester, in addition to five fire drills during the school year. There are also fire drill requirements for healthcare and assisted living facilities.
