Which term is defined as a set of step-by-step instructions compiled by an organization to help workers carry out routine operations?

• A. System Integration
• B. Ventilation
• C. Standard Operating Procedure (SOP)
• D. Troubleshooting

Answer: (C)

A set of step-by-step instructions compiled by an organization to help workers carry out routine operations is called a Standard Operating Procedure. SOPs lay out the exact sequence of actions, needed tools, safety notes, and acceptance criteria so that anyone trained can perform tasks the same way every time. This consistency helps prevent mistakes, speeds training, and supports safety and regulatory compliance. In flammable-refrigerant refrigeration systems, SOPs would cover how to start and shut down equipment, conduct leak checks, handle refrigerants and flammable materials safely, operate detection devices, manage ventilation, and respond to emergencies, ensuring routine tasks are performed correctly even under stress. System Integration is about combining subsystems into a larger functioning system, not about providing routine task instructions. Ventilation focuses on moving air for air quality or contaminant control, not on documenting standard procedures. Troubleshooting centers on diagnosing and fixing problems, which is reactive rather than describing standard operations.
