1, the work site respiratory dust concentration exceeds the exposure concentration management limit of 10 times or more, immediately stop the operation and report to the mine scheduling office, the scheduling office notify the relevant leaders to analyze and deal with.
2. In accordance with the cycle of occupational health checkups, organize the workers to have occupational health checkups, and find out the suspected pneumoconiosis patients, they should be reviewed and diagnosed in time and transferred out of the dust positions. After diagnosis, it should be reported and treated in time.
(B) toxic and hazardous gas poisoning occupational disease hazards
1, to take effective personal protection
Emergency rescue personnel entering the scene of the accident must be based on the occurrence of poisoning of poisons, choose to wear personal protective equipment. Into the half-water gas, carbon monoxide, hydrogen sulfide, carbon dioxide, nitrogen and other poisoned accident scene, must wear a gas mask, positive pressure respirator, wear fire protective clothing; into the liquid ammonia poisoning accident scene, must wear a positive-pressure respirator, wear airtight protective clothing, while doing a good job of protection against frostbite.
2, inquiries, investigation
rescue personnel arrived at the scene, should immediately ask the poisoned, trapped people; the name of the poison, the amount of leakage, etc., and arrange for investigators to carry out reconnaissance, including the confirmation of poisoning, the location of the trapped people; leakage diffusion area and around the ignition source, concentration of leaking substances, etc., and the development of disposal of specific programs.
3, to determine the alert area and attack route
Comprehensive reconnaissance, to determine the alert area, set up alert signs, evacuation of the alert area
and rescue of unrelated personnel to a safe area, cut off the fire source, strict restrictions on entry and exit. Rescue personnel in the upwind, side wind direction to choose the rescue attack route.
4, on-site first aid
(1), the rapid evacuation of poisoned people quickly from the scene, transferred to the upwind or side of the wind direction of the air pollution-free areas; conditions should be immediately respiratory and systemic protection, to prevent the continued inhalation of poisoned.
(2), immediately remove the contaminated person's clothing; skin contamination, with flowing water or soapy water thoroughly rinse; eye contamination, with a large number of flowing water thoroughly rinse.
(3), breathing, heart stopping people, should be immediately artificial respiration and heart squeeze, take cardiopulmonary resuscitation measures, and give oxygen inhalation.
(4), serious cases immediately sent to the hospital for observation and treatment.
5, exclude dangerous situations
(1), banning fire and explosion suppression. Rapidly remove all fire, power, heat and chemical nature of the leakage of all the items in the cordon area, strengthen ventilation to prevent combustion and explosion.
(2), dilution and dispersion. In the leakage tanks, containers or pipelines set up around the spray gun, with a large number of spray water, blooming water flow for dilution, inhibit the direction of the leakage drift and drift height. Indoors to strengthen the natural ventilation and mechanical exhaust.
(3), neutralization and absorption. High concentration of liquid ammonia leakage area, spray mist containing hydrochloric acid in water and, dilute, dissolve, construct a dike or dig a pit to shelter a large amount of wastewater generated.
(4), shut down the valve to cut off the source. Arrange for operators familiar with the scene to close the leak upstream and downstream valves and feed valves, cut off the leakage pathway, in the process of treatment, should use fog water and bloom water with the completion.
(5), apparatus plugging. The use of plugging tools and materials to plug the leakage point for leakage treatment.
(6), pouring transfer. Liquid ammonia tank leakage, in the case of 'can not be plugged', the leakage of liquid ammonia tanks can be poured into a spare tank or liquid ammonia tanker.
6, decontamination
(1), dike plugging. Embankment plug leakage of liquid or diversion to a safe place, the tank area in the event of liquid leakage, to close the rain valve in a timely manner, to prevent the material outflow along the open ditch.
(2), dilution and cover. For carbon monoxide, hydrogen, hydrogen sulfide and other gases leakage, in order to reduce the concentration of gas in the atmosphere, to the gas cloud spray mist water to dilute and disperse the gas cloud, at the same time can be used to move the fan, accelerate the gas diffusion to the high altitude. Liquid ammonia leakage, in order to reduce the evaporation to the atmosphere, can be used to spray fog water to dilute and dissolve or use hydrochloric acid-containing water jets to neutralize and inhibit its evaporation.
(3), shelter (set). For a large number of leaks, you can choose to pump the leaked material to the container or tanker; when the leakage is small, the available adsorption materials, neutralization materials and other absorption and neutralization.
(4), waste. The collected spills are transported to the waste disposal site for disposal, and the remaining small amount of material is flushed with fire water, and the flushing water is discharged into the sewage system for disposal.
(C) high-temperature occupational disease hazards
1, mild heatstroke patients, let them quickly leave the high temperature or sunshine operating environment, to a well-ventilated or cool place, appropriate wind and give a cool drink, a little rest can be returned to normal; headache, dizziness, nausea and other symptoms can be given to obvious heatstroke medication can be quickly returned to normal.
2, severe heatstroke, should be sent to the hospital rescue treatment, according to the condition of the water and electrolyte supplementation, respectively; coma should be actively dealt with coma, and to pay attention to the prevention of shock and cerebral edema
the occurrence of.
(D) noise occupational disease hazard accident
1, if the equipment failure, abnormal noise or noise indicators exceeding the highest national standards, we must immediately stop the operation of the equipment, open the standby equipment and notify the mine scheduling office.
2, regular physical examination found that the employee hearing serious decline or serious irritability, should be promptly transferred from the original workstation.
(E) chemical occupational disease hazards accident
1, chemical skin burns disposal
(1) immediately move away from the scene, quickly remove the chemical contaminated clothing, shoes and socks, etc.;
(2) immediately with a large number of water or tap water to rinse wounds for 10 to 15 minutes;
(3) fresh wounds do not arbitrarily apply ointment or red potion;
(4) depending on the burns sent to the hospital for treatment.
2, chemical eye burns disposal
(1) quickly at the scene with flowing water rinse;
(2) rinse eyelids must be broken open;
(3) if there is no rinsing equipment, you can bury your head into the clean basin of water, break the eyelids, rotate the eyeball washing.
3, acid (sulfuric acid, hydrochloric acid) burns disposal
(1) burns with a cloth to wipe clean, and then rinse with a lot of water;
(2) burns such as water directly rinse will cause local burns parts of the injured area is more enlarged, because of the meeting of the acid and water will be initiated to accelerate the heat reaction;
(3) serious burns, immediately sent to the hospital for medical attention. The first thing you need to do is to get to a hospital and get some medical attention.
(F) poisoning occupational hazards
(1) acute poisoning should be immediately sent to the hospital for first aid, and provide the hospital with the cause of poisoning, the name of the poison, etc.;
(2) if you can not immediately arrive at the hospital, you can take on-site first aid: inhalation of poisoned people, quickly get out of the scene of poisoning, upwind to fresh air, loosen the patient's collar and pants; oral poisoning, the patient's collar and pants. The patient's collar and trouser belt are loosened. For those who are poisoned by mouth, the poison should be spat out immediately by inducing vomiting.
Emergency measures for occupational hazards [Part 2]
1, the earliest found occupational hazards of the accident departments and personnel, should immediately to the dispatch office alarm, and take all measures to cut off the source of occupational hazards of the accident.
2. After receiving the alarm, the dispatching room should quickly notify the relevant departments, quickly identify the location and scope of the accident of occupational disease hazards, and give the instruction to start the emergency rescue plan, and at the same time issue an alarm to notify the members of the leading group and the medical ambulance team and various professional teams to quickly rush to the scene of the accident of occupational disease hazards.
3, the leading group members according to the nature and scale of occupational disease hazard accident, notify the communication team to quickly report to the higher authorities occupational disease hazard accident.
4, members of the leading group arrived at the scene of the accident of occupational hazards, according to the state of the accident of occupational hazards and the degree of harm to make the appropriate emergency decision,
and order the emergency rescue groups to immediately carry out rescue. If the occupational disease hazard accident is expanding, support should be requested.
5, when the occupational hazard accident is under control, immediately set up an occupational hazard accident investigation team to investigate the causes of occupational hazard accidents and study and formulate preventive measures and set up repair teams to study and formulate repair programs and immediately organize repair and resume production as soon as possible.
