Final answer:
The claim that external and internal emergency responders do not need escorts is false. Escorts can provide critical site-specific knowledge and guidance during emergency situations.
Step-by-step explanation:
The statement 'External and internal emergency responders do not need escorts' is False. In many emergency situations, especially within complex facilities such as industrial plants, hospitals, or large educational campuses, emergency responders may indeed require escorts. These escorts are generally knowledgeable about the site's layout, potential hazards, access points, and any other relevant information that could influence the efficiency and safety of the response effort. Therefore, having an escort can be crucial for guiding emergency personnel quickly to the location where they are needed, and in helping them navigate any obstacles or risks present.
