What should always be followed when operating a machine for safety?

The correct answer revolves around the importance of following Standard Operating Procedures (SOP). SOPs provide a clear and systematic approach to operating machinery safely and effectively. They are established guidelines that outline the step-by-step processes and safety measures that should be adhered to during machine operation. This structured approach ensures that everyone understands how to operate machinery properly, reducing the risk of accidents and injuries.

SOPs are typically developed based on industry best practices, regulatory requirements, and insights gained from past experiences. By following these procedures, operators can ensure consistency, maintain quality, and uphold safety standards. In high-risk environments, the absence of SOPs can lead to mistakes due to misunderstandings or variations in individual practices, increasing the likelihood of unsafe conditions.

In contrast, while product manuals, workplace posters, and manager's instructions can also contribute to safety, they may not provide the comprehensive, standardized approach that SOPs offer. Product manuals often focus on the specifics of a machine or product, whereas posters are meant for quick reminders and may not cover all procedures in detail. Manager's instructions can vary from one person to another and may lack the consistency and thoroughness of SOPs. Therefore, relying on SOPs ensures that all operators are on the same page and minimizes risks associated
