How long can a plant operate without a chief engineer?

A plant can operate without a chief engineer for up to 7 days due to safety regulations and operational standards designed to ensure the safe management of the facility. This timeframe allows for the identification of a qualified replacement, ensuring that operations can be maintained without compromising the integrity of engineering practices. It recognizes that while continuous supervision is critical for safety and compliance, a short period without a chief engineer is permissible as long as proper protocols and procedures are followed during that time. This provision is in place to minimize disruption while ensuring that safety is not compromised during the transition period.
