Buses are more dangerous when braking sharply and making sharp turns. Passengers often lose their center of gravity and can even be thrown out of their seats, slip and fall. In addition to the need to improve the bus driver’s driving skills and awareness of safe driving, as a passenger, what do you need to pay attention to? Let’s first look at the bus’s supporting facilities. General buses have facing front, rear and side seats and standing space. The vast majority of buses in the center for the aisle, the last row of the central position in front of the aisle, the other seats in front of more seats or rails for hand-holding grip. Buses have more hand grip pull ring, up and down the doorway and other places have a number of vertical rails, and the rails above the head, these rails can be used as handrails grip. Some passengers ride facing the rear of the car standing, once the emergency brake, due to the role of inertia, people will be tilted in the direction of the front of the car. Due to the anatomical structure of the foot, the human body is far less responsive to backward tilting than forward, and, if there are objects behind the heel to trip more easily fall. Once a person’s head and occipital area is injured on the ground, it is often fatal, while falling face forward, can reduce the head and face injury through the support of their own double upper limbs. Even if the head and face knocked, the danger is far from the head and pillow injuries are dangerous. In addition, face backward pulling the handrail, people resist the force of forward inertia is much less than the force of grabbing the handrail or seat back, and the hand grip is not enough when it is cold, pulling the handrail is easy to loosen and slide off. Few buses are equipped with seat belts, if so equipped, try to bring a good seat belt, for their own safety increased protection. The center of gravity of the human body is mainly in the chest and abdomen, if encounter unexpected situation, the seat belt is a life-saving belt. In case of slip and fall in the bus, fall injury, must not panic, the scene correct first aid can greatly reduce the danger, prevent secondary injury. Bystanders should first look at the injured person’s breathing (look at the chest undulation) and heartbeat (feel the carotid pulsation), if there is no breathing to give open airway and cardiopulmonary resuscitation as soon as possible. Secondly, the injured person should be placed in a safe position to avoid aggravating the injury, such as neck injuries, to neck braking, do not do flexion, extension, lateral bending and rotation and other improper activities, to protect the cervical spine may save a person’s life. Third, if the injured limb deformity, mostly fracture or dislocation, please do not reset, should be given temporary fixed braking, maintain the injured position, waiting for professional doctors rescue, on-site reset may aggravate the pain or induce shock. If there is bleeding, especially jet-like bleeding, compress the proximal limb to stop bleeding and avoid excessive bleeding to form hemorrhagic shock.
