Temporary barriers are structures designed to restrict access or control movement for a limited time. They are often used in construction sites, events, or during emergencies to ensure safety and manage crowds. Examples include fencing, traffic cones, and barricades. These barriers can be made from various materials, such as plastic, metal, or wood, and are typically lightweight for easy installation and removal. Their primary purpose is to protect people and property while allowing for flexibility in changing environments or situations.
