Michigan Nursing Home Administrator (NHA) Practice Exam

What is the required fire-resistant rating for smoke barriers in new buildings?

1. 30 minutes

2. 1 hour

3. 2 hours

4. 3 hours

The correct answer is: 1 hour

The correct answer highlights that smoke barriers in new buildings are required to have a fire-resistant rating of 1 hour. This standard is established to ensure that smoke, which can be as dangerous as flames during a fire, is effectively contained within certain areas of a building. The 1-hour rating allows for sufficient time for occupants to evacuate safely and for firefighters to contain the fire. This requirement is in place to enhance the overall safety of the facility and its residents, particularly in healthcare environments where vulnerable populations, such as those in nursing homes, reside. The differing ratings for fire resistance, such as 30 minutes, 2 hours, and 3 hours, are designed for various other applications and building elements but do not apply specifically to smoke barriers in this context. The choice of a 1-hour rating reflects a balanced approach to providing adequate protection without compromising overall building design and functionality.
