Common accidents and preventive measures for glass production enterprises
[China Glass Net] The glass production process mainly includes the ingredients, melting, forming, annealing and cutting processes, which also determines the high-speed, hazardous chemicals, dust and mechanical equipment in the production process of glass. This leads to safety hazards such as high temperature radiation, fire and explosion, glass scratches and mechanical damage during the glass production process.
High temperature injury and prevention
In the glass production process, the melting furnace used to melt the glass is a continuous operation thermal equipment that releases a large amount of radiant heat and convection heat, and the temperature in the furnace can reach 1450~1600 °C. The temperature in the workshop is high, and the average summer temperature is above 40 °C. Some workers must operate continuously at high temperatures. Such an environment has serious damage to the physiology of workers. Burns caused by workers' illegal operation are also important safety accidents.
To prevent the damage of high temperature to workers, glass manufacturers should strengthen the natural ventilation of the workshop. In the design of the plant, it is necessary to reasonably select the orientation of the workshop and set up enough skylights. The layout of the process equipment in the workshop should be considered as a whole. Timely to add salt and moisture to workers working in high temperature, such as providing salty drinks; using metal plates to separate heat sources from operating workers. In addition, glass production enterprises should strengthen and supervise the workers' own protection, and issue qualified full-scale labor protection products, including protective clothing, protective caps, protective glasses and gloves, in accordance with relevant regulations and actual conditions, and strictly require workers to be correct. Wear it. At the same time, workers are strictly required to abide by relevant operational procedures, clarify job responsibilities, and adopt incentives for rewards and punishments to ensure that measures are in place.
Dust injury and prevention
Dusts are generated by screening, lifting, transporting, weighing and mixing of glass raw materials. The parts are in the batching workshop, the silo feeding port, etc., workers are exposed to these dusts, if improper protection or wearing dust masks or workplaces If the dust concentration is too high, dust damage will occur, which can lead to pneumoconiosis.
In order to prevent the dust from harming the human body, we must do the following work: the batching production process should be mechanized and continuous; the corresponding dust removal system should be configured to do the dust removal work in the workshop; the batching workshop should be placed on the downwind side of the dominant wind in the plant. It should not be too far away from the raw material workshop and the melting furnace; the indoor building structure should minimize the protruding parts that are easy to accumulate dust, and the multi-storey building should have various isolation measures to prevent the flow of dusty air. The ground should be flat and compact, suitable for flushing and Clean up; remove dust in time to meet the requirements of natural ventilation; try to use raw materials with a particle size greater than 0.05 mm; wear labor protection supplies in workers' dust working places; regularly check the dust concentration in the air of the workshop, and regularly check the workers' physical examinations, etc. .
Fire explosion and prevention
The fire and explosion here is mainly due to the inflammable and explosive substances involved in hydrogen, natural gas, coke oven gas, etc. in the glass production process. The fire hazard of these substances is Class A, and the density is less than that of air. In the event of a fire source, it is prone to fire and explosion accidents. In addition, in the initial stage of ignition, if the ignition is not performed according to the prescribed procedure, the mixing ratio of natural gas or coke oven gas to air in the furnace may reach the explosion limit, causing an explosion accident. However, pressure vessels and the like may also be in danger of physical explosion due to overpressure, safety valve failure, etc., and shock waves and debris generated by the explosion may cause damage to buildings, equipment or people, and may cause fire and other safety accidents.
To this end, the glass production enterprise should set up a gas leak detection alarm device in the place where the above substances are involved. In addition to being placed above the release source, the alarm device should also be set at a place where the gas at a higher point in the plant is easy to gather. The gas leakage alarm signal shall be sent to the manned control room and the on-site operation room. The gas detection and alarm system fixedly installed on site shall be powered by an uninterruptible power supply.
Improve the setting of explosion-proof electrical to prevent static electricity. The fire hazard of hydrogen, natural gas and coke oven gas are all Class A, which has the risk of fire and explosion. Therefore, these gas areas must be equipped with explosion-proof electrical equipment, and their explosion-proof electrical grades must comply with relevant requirements. In places where such gases are involved, anti-static overalls and anti-static shoes should be provided for the operators to prevent static build-up of the gas.
Improve fire fighting facilities. Glass production enterprises must strictly comply with the relevant fire protection requirements, properly and reasonably equipped with fire-fighting facilities, regular inspections, and good maintenance to ensure that they are in good condition. Once the fire occurs in hydrogen, natural gas or coke oven gas, the gas source should be cut off immediately. If the air supply cannot be cut off, it is not allowed to extinguish the flame at the leak.
Glass scratching and prevention
Glass scratch workers are a kind of safety accidents that occur in glass production enterprises. Because of the weak safety awareness of operators and the three-dimensional cross-operation of equipment, there are many hidden dangers in safety accidents, mainly in glass pick-up and finished product transportation. Broken glass treatment, glass finished product transportation equipment maintenance operations and other parts, leading to the occurrence of safety accidents such as cutting fingers and crushing the arm.
To prevent the occurrence of accidents caused by scratched glass workers, it is important to do a good job in protecting workers. In particular, the process of glass cutting, edge drawing, crushing, etc., workers must strictly follow the requirements of the regulations to do the necessary protection, and must not save trouble in this aspect, arbitrarily arbitrarily, and can not be lucky. When transporting semi-finished products, apply the rope bundle firmly. It is strictly forbidden to stand on the forklift to support the glass. To handle the broken glass, wear protective equipment. The maintenance equipment must strictly follow the operating specifications.
Mechanical injury and prevention
In the glass production process, mechanical damage often occurs in the feeding machine, belt conveyor, crusher, shredder, edger and other parts, as well as damage caused by special equipment, such as crushing, collision, shearing, cutting and other injuries.
There are two main reasons for mechanical damage. One is that the machine itself has safety hazards, and the other is that the operator violates regulations or operates improperly. Specifically, the equipment is not regularly inspected and rectified, or the equipment is not inspected seriously, the fault is not reported in time, and the equipment is not used correctly. The operation process does not meet the requirements of the operating procedures, the operating procedures are insufficiently trained, and the restricted access area is entered without permission. During the maintenance process, the power supply wiring does not meet the requirements, the maintenance equipment is not inspected before use, and the on-site equipment pipeline signs are improperly suspended. In addition, the operation of special equipment such as forklifts and cranes, including speeding, improper storage of keys, inadequate inspection of equipment before use, and improper operation of the operation process, poses hidden dangers for the occurrence of safety accidents.
In order to prevent the "sickness" of mechanical equipment, glass production enterprises should set up special management personnel to carry out regular and daily inspection and maintenance of mechanical equipment, and arrange the renewal plan for equipment and equipment that are ineffective and need to be eliminated. replace. For each special job position, the glass production enterprise should carry out re-training of post operation procedures to improve the operation level of special types of work. Special operation personnel must be trained in special safety operations in accordance with relevant state regulations, and obtain corresponding qualifications before they can be employed.
Strengthen safety management
Glass production enterprises must adhere to the "safety front, prevention-oriented" safety production policy, and must be safe while pursuing economic benefits.
Strengthen daily supervision and management, such as the necessity of post-class work of glass production enterprises, and always remind workers to pay attention to safety and standard operation. Do a good job in daily inspections and find out where the safety measures are not in place to point out the rectification in a timely manner, and stop the unsafe behavior of workers in time.
Strengthen safety education and training. Through safety education and training, workers are fully aware of the serious consequences of illegal operations and numbness. For some workers whose technical skills are not well-skilled, it is necessary to increase the intensity of training and strictly regulate the operation; for skilled workers, it is necessary to repeatedly slap and supervise, and should not be complacent. Only by putting safety in the heart and practicing it in practice can we truly ensure safety.
Supervise workers to standardize the wearing of labor insurance products. In the glass production process, there are potential safety hazards in many aspects, such as high temperature, mechanical damage, glass cuts, etc. If the labor insurance products are not properly worn or worn, it is prone to serious safety production accidents. In addition, companies should choose formal channels to purchase qualified products and store them as required, and avoid the performance of labor insurance products due to improper storage.
