In what circumstances should an engineer refrain from leaving the premises while on duty?

An engineer should refrain from leaving the premises while on duty when equipment is malfunctioning because it is their responsibility to ensure the operational safety and functionality of systems within the facility. If equipment is not working correctly, leaving could exacerbate the issue, lead to safety hazards, or create loss of service. The presence of the engineer is critical for troubleshooting, implementing immediate corrective actions, or managing emergency responses to prevent further complications.

In contrast, scenarios involving snowstorms, orders from management, or routine maintenance may not require the engineer's immediate presence in the facility, depending on the specific protocols established by the organization. However, when equipment is malfunctioning, the potential risks involved necessitate the engineer's ongoing attention and response, underscoring their role in maintaining system integrity and safety.
