Which statement correctly reflects Certificates of Registration?

• A. They are optional for most projects.
• B. They must be posted conspicuously.
• C. They are required before starting work.
• D. They may be transferred between firms.

Answer: (C)

Contracts and crews working on fire sprinkler systems must hold a valid Certificate of Registration before any work begins. This credential shows the firm or individual is legally authorized and meets the state’s licensing, training, and insurance requirements, ensuring the people on site are qualified to perform the installation and related tasks. Because safety and code compliance depend on proper qualifications, starting work without an active registration isn’t allowed and can lead to stoppages or penalties.

Posting the certificate conspicuously isn’t the primary rule in this context, even though some jurisdictions may require posting for visibility. The essential point is that work can’t start without an active registration. Likewise, transfer of a certificate between firms isn’t simply automatic; registration is issued to a specific entity and typically requires a separate action to transfer or reissue when the firm changes.
