The need for a fire watch is typically indicated by hot work being performed in areas where flammable materials are present. Hot work encompasses activities such as welding, cutting, grinding, and similar operations that can generate heat and sparks, posing a significant fire risk. In such circumstances, a fire watch is essential to monitor for any signs of fire or smoke, ensuring quick response to any potential incidents. This precaution is critical where combustible materials could ignite, thereby preventing accidents and safeguarding lives and property.

The other choices do not directly pertain to situations that would necessitate heightened fire precautions like a fire watch. Routine building inspections may help identify safety hazards but do not inherently justify a fire watch. Frequent employee training on fire safety is important for overall preparedness but does not indicate an immediate need for a fire watch. Lastly, the installation of new fire alarms enhances fire safety but does not relate to the conditions that would require an active fire watch to mitigate specific risks associated with hot work activities.
