NFPA Exam CFI-I Topic 4 Question 1 Discussion

Comprehensive and Detailed Step-by-Step Explanation:

Labeling Hazardous Materials:

Per NFPA 704 (Standard System for the Identification of the Hazards of Materials for Emergency Response) and OSHA regulations, hazardous materials must have conspicuous marking or labeling that meets recognized national standards.

Purpose of Conspicuous Marking:

Clear identification ensures emergency responders, workers, and occupants can recognize and handle hazardous materials safely.

Other Options Explained:

Option A (No special identification): Incorrect; labeling is mandatory.

Option B (Unique color coding): While color coding is part of the system, it must align with national standards, not a unique system.

Option D (Owner's requirements): Owner-specific markings may not comply with NFPA or OSHA standards.

Summary:

Hazardous material containers must have conspicuous marking or labeling meeting national standards.
