In what situations is the use of flags limited?

The use of flags is primarily limited in emergency situations and controlled locations because these environments have specific safety protocols and communication needs. In emergencies, clear and effective communication is crucial, and using flags may mislead or interfere with essential signals or instructions. Controlled locations, such as those with regulated traffic patterns or specific safety requirements, demand consistency and clarity in signaling to prevent confusion and ensure safety. These settings often rely on more standardized signage and signals rather than flags, which can be interpreted differently by different individuals.

While daily operations for visibility and regular construction site signage might involve flags for directional or warning purposes, these uses are generally considered less critical than the clarity required in emergency and controlled settings. The limitation of flags in emergency situations helps to ensure that the most effective communication methods are used to manage risks effectively.
