What practice is generally recommended if smoke or heat in the stairwell is present?

When smoke or heat is present in the stairwell during a fire emergency, the recommended practice is to move to another floor that is deemed safer. This choice is based on the understanding of smoke and heat behavior in high-rise buildings. When smoke fills a stairwell, it can pose a significant danger to occupants attempting to evacuate. By seeking a safer floor, individuals can escape the immediate threat and find a location where they may have access to clearer air and potentially better conditions for survival.

In addition, moving to another floor can also provide access to windows, breathable air, or rescue points like fire department ladders or platforms that might be safer and more accessible. The strategy encourages occupants to stay aware of their surroundings and be adaptable, especially in situations where the fire or smoke may restrict their options. Prioritizing a safer area, rather than returning to the office, evacuating to the roof, or remaining on the ground floor, maximizes the chances of avoiding smoke inhalation and heat exposure, and ultimately enhances survival during a crisis.
