In the HAZOP (Hazard and Operability Study) process, guide words play a crucial role in identifying possible deviations from the intended operation of a process. These guide words are used to prompt team members to think critically about how a process can deviate from its design intentions. For example, guide words such as "more," "less," "no," and "as well as" help explore different ways a system can fail or operate outside of its designed parameters.

By focusing on these potential deviations, the HAZOP team can systematically evaluate how those deviations might lead to hazards or operational issues. This thorough examination is essential for identifying risks and formulating recommendations to mitigate those risks, ultimately ensuring safer and more efficient processes.

The other options do not accurately represent the primary function of guide words in the HAZOP study. While they might play a role in other evaluation contexts, they do not align with the specific purpose of guide words in identifying deviations.
