The area around ports where cargo is handled is securely fenced.
Security guards make sure that only those people who have permission to visit a
port can go in. There are usually security cameras and precautions for
keeping unwanted people out.
Security is very important in ports.
• Wharfs are very dangerous places for people to be
wandering around. There could be many large transport machines and
cranes at work. Large conveyors can also be dangerous.
