Pathway survivability Level 1 consists of pathways in buildings that are fully protected by an automatic sprinkler system, with any interconnecting conductors, cables, or other physical pathways protected by which of the following?

Pathway survivability Level 1 consists of pathways in buildings that are fully protected by an automatic sprinkler system, with any interconnecting conductors, cables, or other physical pathways protected by which of the following?

• A. Metal raceways
• B. Open air
• C. Plastic conduits
• D. Fiber optic cables

Answer: (A)

Pathway survivability Level 1 relies on robust physical protection for all conductors and pathways within sprinklered buildings. Metal raceways provide noncombustible, mechanically protective enclosures that resist damage from heat, flame, and impact, helping keep electrical circuits intact during a fire and reducing the chance of fire or water from compromising the pathway. Open air offers no protection, plastic conduits can soften or fail under fire conditions, and fiber optic cables, while valuable for data, do not provide the same level of mechanical protection as metal raceways for electrical pathways in a sprinkler-protected environment.
