Self-help, the most basic escape skills we need to master
Terrorist attacks are man-made attacks by extremists against but not limited to civilians and civilian installations that do not conform to international morality.
Since the 1990s, terrorist attacks have had a severe tendency to spread rapidly around the world. The methods used by extremists have also evolved from the initial pure military strikes to kidnappings, massacres of civilians, suicide bombings and other terrifying actions. Terrorist attacks occur almost every day in Baghdad, and the 9/11 incident in the United States is the worst terrorist attack that shocked the world. Therefore, from the beginning of this century, the major military powers, mainly the United States, began to emphasize the arrogant spread of the global anti-terrorist alliance in an effort to combat terrorism.
Although we often say that things like 911 happen once in a lifetime, some people say that they are not so unlucky, how come they will encounter a terrorist attack? Some people say that our society is relatively stable and no terrorist attacks will happen.
There is an old saying in China that is good, not afraid of 10,000, just in case. So be prepared and be prepared. Although we do n’t want everyone to encounter a terrorist attack, what if we encounter an accident? Life is critical, and we must change our mindset. When an accident occurs, the person who first provides effective care to the injured is our own. Winning time means keeping life. Master more self-help methods of first aid to make fragile lives stronger. If we save each other by ourselves, what we save is a living life.
How to carry out self-help and mutual aid in an emergency?
(1), hemostasis is first transferred to a safe or quiet place, check the injury, determine the nature of bleeding, such as arterial bleeding, venous bleeding, capillary bleeding; you can use your finger to press the bleeding wound or bleeding blood supply artery to stop bleeding ; For wounds and bleeding in the extremities, use belts, ties, identification belts, coarse cloth strips, silk scarves, or you can tear your clothes into strips instead, bandage and stop bleeding at the upper third of the arm and the middle of the thigh
(2) To fix open wounds, wrap the wound first and then fix it. Do not return the punctured fracture end; cushion or raise the injured part to slow bleeding and reduce swelling. Do not move the spine or those suspected of having spinal injuries; when fixing, the upper and lower joints of the fractured end must be fixed together. If the calf is fractured, the ankle and knee joints should be fixed.
(3) First aid for burns: Wash the wound with plenty of clean water, unless the wound is black, whitened, or too deep; do not apply ice directly to the wound; do not pierce the blisters; gently remove the ring, watch, belt, or tight clothing ; Cover the wound with a clean, non-sticky cloth.
(4), shock first aid to avoid the cold or overheat of the injured, use blankets or coats to keep warm; if there is no fracture, raise the feet of the injured about 30 cm; do not drink or feed the injured; pay attention to the soberness of the injured; Ambulance report.
(5) First aid for respiratory obstruction can use ID card or other non-absorbent card to stick to the body to press the wound; you can also use plastic wrap film, tear off the size of about 20 × 20 cm, stick to the wound, and fix it with tape Hold the upper, left, and right sides, leaving the lower side to allow the blood from the wound to drain out; you can also open your palm and press the wound against the body.
(6) If the first aid for abdominal injury is a closed wound, the wound should be pressed in time. If it is an open wound, when the small intestine is exposed, the coat should be moistened with water to cover the small intestine and not exposed to the air. Never refill the abdominal cavity with contaminated internal organs; try not to move after being injured, and take a lying or lying position to wait for rescue.
(7) The CPR rescuer lays the injured person on his back, taps his shoulders and calls, and presses the middle point of the person and calls. If there is no response, the person is judged to have lost consciousness; raise the jaw angle to make the airway unobstructed; if the injured person still cannot breathe, perform mouth-to-mouth artificial respiration. If the above artificial respiration does not work, check the mouth and throat for foreign objects, and try to eliminate it to continue the artificial respiration; the artificial breathing technique is: push the head back and push the jaw up. Take a deep breath and mouth to mouth, sometimes mouth to nose. Pay attention to pinch your nose and blow the air, 16-18 times per minute. Heart massage. Once the patient's heart is stopped, immediately tap the patient's sternal body in the precordial region 2 or 3 times. If it is not effective, perform a chest heart massage immediately. Let the patient lie on his back with a hard board on his back. The operator kneels next to the patient and puts the palm of his hand on the middle and lower 1/3 junction of the patient's sternum body. Straight, using the weight of the operator, squeeze the sternum downwards to make it sink by 3 cm (reducing the force applied to the child patient) and then relax and reset the sternum, so repeat it, about 70 to 80 times per minute.
These points cannot be ignored in the construction of steel structure workshop
The cost of the steel structure factory building is low, and the construction efficiency is high. It only needs to complete the basic design, and the construction can be completed immediately, and the factory building can be put into use quickly. However, when building a factory, we still have to pay special attention to the following points.
simple design
Different from other buildings, the steel structure factory building should still have a simple shape, generally designed as a rectangle, so that it is more convenient to use later and can also ensure the internal space. The layout can be carried out according to the terrain of the site, and attention must be paid to the specific design location of the workshop and whether there is a certain functional area division. Generally, the terrain slope of the factory building should not be greater than 5%, and the hilly slope should not be greater than 40%. Therefore, the construction should be carried out according to the local conditions, and the slope should be reasonable.
Construction location confirmation
As far as possible, the factory building should avoid locations such as earthquake faults, especially some locations prone to mudslides and landslides are not suitable for building factory buildings. If it is a valuable mining area, ancient tomb, etc., try not to build factories, etc. Before the construction of the factory building, it is necessary to do a good on-site inspection. If the local area is not suitable for the construction of the factory building, try to choose another place, so as to avoid the need to relocate the factory building later, which will be more troublesome and waste time and construction costs.
Reserved land for expansion
Steel structure workshops are very easy to expand, because with the increase in later construction requirements, many workshops may need to be expanded. Therefore, at the beginning of construction, a place for expansion should be reserved. At least the process requirements, transportation requirements, and whether there are other plant constructions should be considered.
Pay attention to construction inspection Steel Structure Workshop and Steel Structure Warehouse are relatively easy to construct and construct, so it is still necessary to pay attention to the need for safety personnel to inspect the site, and report in time if there are some installation problems. Moreover, after the construction is completed, there must be a construction inspection, and the stability of the plant must be ensured, so as not to affect the later use of the plant.
It is only necessary to select the appropriate materials for the construction of the steel structure factory building, and choose a suitable construction location, then basically the construction of the factory building can be completed immediately, and the factory building can also be quickly put into later use.
