What is one of the roles of fire inspectors as mentioned in the passage?

The role of fire inspectors primarily involves examining structures to ensure they comply with fire codes and safety regulations. This critical task allows them to identify potential fire hazards, assess the condition of fire protection systems, and ensure that safety measures are adequately implemented. By conducting thorough inspections of buildings, fire inspectors play a vital part in preventing fire incidents and ensuring public safety. Their assessments contribute to creating compliant and safe environments for occupants, ultimately reducing the risk of fire-related emergencies.

The other options represent tasks that may be associated with fire inspection or related fields but are not the primary responsibility of fire inspectors. For instance, while appearing in court and talking to witnesses may involve legal proceedings related to fire events, they are not direct duties of fire inspectors in their regular roles. Similarly, lecturing on fire safety could be part of a fire inspector's community outreach work but is not their main function. The primary focus remains on the detailed examination of structures to ensure adherence to safety standards.
