At the same time in the construction of the site to do a good job of guidance and inspection, and adhere to the acceptance of the subsequent construction only after passing. For high support mold, high support mold in construction, the technical department will carry out the whole construction phase of continuous monitoring, and do emergency rescue measures.
6, safety emergency plans and measures
① emergency rescue organization
② division of labor and responsibilities
(1) immediately after the accident, the rescue of victims, organization of the evacuation or to take other measures to protect the hazardous area of other people. Rescue victims is the primary task of emergency rescue, in the emergency rescue operations, the requirements of rapid, orderly and effective implementation of on-site first aid and safe transfer of the injured to reduce the rate of injury, reduce the loss of the accident.
(2) guide the masses to protect, prevent the development of the situation, and organize the safe evacuation of the masses from the scene.
(3) rapid control of the source of danger, the hazards caused by the accident monitoring, determination of the accident hazardous area, the nature and extent of the hazard. (4) find out the cause of the accident, identify casualties, and assist the company and other higher authorities to investigate the accident. (5) Do a good job of site cleaning, reduce and eliminate accident traces.
③ plan and emergency measures
1, the principles of work
After the accident, rescue work should be carried out in an orderly manner, serious and serious accidents, emergency rescue work in accordance with the "protection of personnel safety is given priority to preventing and controlling the spread of accidents, the expansion of the main; unified leadership and command, division of labor, grading responsibility, comprehensive coordination, rapid and efficient, The principle of "combining self-help on the scene with rescue from higher levels or society".
Personnel first aid steps: first aid is to provide emergency supervision and treatment of the injured, to give the injured the greatest chance of survival, first aid must
follow the following four steps:
(1) investigation of the accident scene, the investigation to ensure that the investigator, the sick and wounded or other people are not at risk, and quickly make the sick and wounded out of the dangerous places, especially in the construction site of large-scale accidents, especially so. More so.
(2) preliminary examination of the sick and wounded, determine their sanity, trachea, respiratory circulation problems, if necessary, immediately on-site first aid and supervision, so that the sick and wounded to maintain an open airway, as appropriate, to take effective measures to stop bleeding, to prevent shock, bandage wounds, fixation, preservation of organs or tissues disconnected, prevention of infection, pain relief, etc.
(3) the accident scene, to ensure that no danger to investigators or others, especially in large construction site accidents, more so.
(3) call for help, should be asked to call an ambulance, you can continue to rescue, has to insist on ambulance personnel or other rescuers arrived at the scene to take over. At this time should also reflect the injury of the sick and wounded and a simple process of treatment.
(4) If there is no sign of a critical injury, you can make a second check, so as not to miss other injuries, fractures and lesions. This is conducive to the scene to implement the necessary first aid and stabilize the condition, reduce complications and disability rate.
2, lifting machinery injury first aid measures
When the mechanical injury occurs, the injured should be moved as soon as possible to support the safety of the location of bandaging, bleeding, fixation of the injured limb, emergency after the timely delivery of hospital treatment.
(1) hemostasis ① types of bleeding
arterial hemorrhage: bright red blood, bleeding objects like a small fountain spray, time piggyback for a long time, there will be life-threatening; venous hemorrhage: dark red blood, bleeding slowly out of the time, there is also a danger of a long time; capillary hemorrhage: bright red blood, bleeding blood from the entire surface of the injury oozing, often coagulate automatically. ② hemostatic methods
There are generally four methods of hemostasis, namely, pressure bandage hemostasis, acupressure hemostasis, plug hemostasis and tourniquet hemostasis. Pressure bandage hemostasis: use hemostatic gauze or clean towels, fabrics folded into a larger than than the slightly larger cushion to cover the wound, and then use a triangular towel or bandage pressure bandage, you can achieve the purpose of stopping the bleeding.
Finger-pressure hemostasis: Use your fingers or palm or palm to press the upper part of the bleeding blood vessel (the end near the heart) hard to the bone underneath it, blocking the source of blood, to achieve the purpose of temporary hemostasis.
Plugging hemostasis: Plug the sterilized cotton or gauze in the wound, and bandage it with pressure, which is suitable for hemostasis of armpit, shoulder and thigh wounds.
Tourniquet hemostasis: tourniquet hemostasis is suitable for large blood vessels bleeding, especially arterial bleeding, when the use of pressure bandage hemostasis method can not effectively stop the bleeding can be used in this way, commonly used rubber tube as a tourniquet, can also be used in place of a bandage, triangular towel, cloth tape, etc., the use of a tourniquet to remember the six words: fast, accurate, cushion, on the, suitable, put.
Quick: fast action, grab time;
Accurate: see the bleeding point, accurate bandage; pad: pad on the pad, do not tie directly to the skin;
on: tied to the top of the wound, close to the wound outlet, but forbidden to tie to the mid-upper arm; suitable: tight and loose to stop bleeding, can not feel the distal pulse as appropriate;
