The NPIS final rule includes a provision that prescribes maximum line speed rates under the NPIS to emphasize establishments' existing legal obligation to comply with OSHA laws.

• A. It sets minimum line speeds only
• B. It does not address line speeds
• C. It is implemented differently in some plants
• D. It prescribes maximum line speed rates to emphasize OSHA compliance

Answer: (D)

The key idea is that the NPIS final rule uses a cap on line speeds to reinforce that facilities must follow OSHA safety requirements. Setting maximum line speed rates provides a clear, enforceable limit that aligns with existing OSHA obligations, so plants can’t rely on high speeds to justify unsafe working conditions. This approach directly communicates that OSHA compliance is a non-negotiable part of operating under NPIS, rather than creating a new minimum speed or implying that speeds aren’t addressed. While actual practices may vary from plant to plant due to equipment, the rule’s purpose is to establish a safety-oriented ceiling that underscores OSHA compliance across facilities.
