Which type of construction is commonly found in the context of high life safety hazards?

Type 1 construction, which consists of non-combustible materials such as concrete and steel, is widely recognized for its superior fire-resistance qualities. This type of construction is specifically designed to withstand fire for an extended period, thereby significantly enhancing life safety. Buildings constructed with these materials have a high degree of fire resistance, which is crucial in environments where life safety hazards are a major concern.

Due to its structural resilience and minimal flame spread potential, Type 1 construction is often utilized in high-rise buildings, hospitals, and other facilities where a large number of occupants may be present, thereby necessitating higher safety standards and rigorous fire protection measures. The advanced fire-resistance ratings associated with Type 1 construction help ensure that occupants have a safe means of escape in the event of a fire.

In contrast, the other types of construction mentioned tend to be less fire-resistant, making them less suitable for high life safety hazard contexts. Type 2 construction is non-combustible but does not provide the same level of fire resistance as Type 1; Type 3 and Type 5 constructions include combustible materials, which increase the fire hazards and therefore are not ideal in scenarios that have significant life safety risks.
