What is a key factor when determining a signal person's location?

When determining a signal person's location, having an unobstructed view of the operator and the load being moved is crucial for safe and effective communication. This visibility allows the signal person to accurately convey instructions based on the load's position and the operator's actions, reducing the risk of accidents and ensuring that operations proceed smoothly. The signal person must be able to see not only the crane operator but also the load to make informed decisions and provide clear signals.

The other options, while they may have some relevance to comfort or convenience, do not directly support the primary responsibility of a signal person, which is to maintain effective communication and situational awareness during lifting operations. Proper placement ensures that potential hazards are recognized and mitigated, ultimately prioritizing safety on the job site.
