Standard symbols for fire protection are found in NFPA which standard number?

• A. NFPA 70
• B. NFPA 170
• C. NFPA 13
• D. NFPA 101

Answer: (B)

Using a consistent set of symbols in fire protection drawings and signs is essential for quick, accurate understanding by anyone reading the plans or responding to an incident. The standard that defines these symbols is the fire safety symbols standard, which lays out icons for equipment like fire alarms, extinguishers, exits, doors, sprinklers, and related safety features. This makes diagrams universally readable regardless of who drew them or where the building is located. The other NFPA standards focus on different topics—electrical wiring, sprinkler system installation, or general life-safety requirements—without specifying a universal symbol set. So the symbol standard is the one that directly answers the question.
