Before each shift, safety regulations require checking equipment for all of the following except:

Safety regulations typically emphasize the importance of performing a thorough inspection of equipment before each shift to ensure safe operation. Checking operational controls, the emergency brake, and the horn all contribute to ensuring that the equipment is functioning correctly and can respond appropriately in various situations.

Operational controls must be checked to confirm that the operator can control the equipment effectively. The emergency brake is critical for safety, as it needs to be fully operational to stop the machine in emergencies. The horn serves as an important warning signal, alerting others in the vicinity when the equipment is in operation.

While checking fuel and oil levels is essential for the overall maintenance of the equipment, it is not specifically mandated by safety regulations to be checked before every shift. Instead, monitoring fuel and oil levels usually falls under routine maintenance checks, which might not require strict adherence before each work period. Thus, the focus on immediate operational safety takes precedence over fuel and oil assessments in the context of shift preparations.
