Which measure enhances fire safety during construction?

Implementing a smoke control system significantly enhances fire safety during construction by managing the movement of smoke and heat, which are major hazards during a fire event. Such systems are designed to remove smoke from the area, thereby improving visibility for evacuation and allowing firefighters to operate more effectively. A smoke control system can help maintain tenable conditions in exit routes, giving occupants a better chance to escape safely.

In contrast, using flammable materials poses a fire hazard by increasing the risk of ignition and rapid fire spread. Blocking all exits would create dangerous conditions, as it hinders evacuation and could trap individuals within a burning structure. Allowing unrestricted access to hazardous materials also increases fire risk, as these materials could contribute to ignition or exacerbate fire behavior. Thus, a smoke control system is a critical component of fire safety measures, particularly during construction when the environment can be unpredictable.
