What do you know about the major risk factors in the process of mineral processing
Beneficiation can greatly improve the quality of raw materials, reduce transportation costs and facilitate treatment. Of course, it will also greatly reduce costs and achieve comprehensive utilization of mineral raw materials. Although ore dressing production can bring us lots of convenience and profits, we have to remind the beneficiation workers. There are still some dangerous factors that we need to avoid in the process of mineral processing.
1. Electrical danger
Electrical hazards are mainly two forms of electrical spark and electrical injury. Electrical hazards are related to electricity. From an energy point of view, the loss of control of electrical energy will cause electrical accidents. According to the form of electric energy, electrical accidents can be divided into electric shock accidents, lightning accidents, electrostatic accidents and so on.
Two. Mechanical injury
The damage of mechanical damage is essentially the abnormal work, flow or transformation of mechanical energy (kinetic energy and potential energy), resulting in contact injury to people. The main forms of mechanical injury are squeezing, rolling, cutting, cutting, winding or involvement, pricking or stabbing, rubbing or wearing, flying objects striking, high pressure fluid spraying, collision and falling.
Three, poisoning and asphyxia
In production engineering concentrator will use nitrate, nitrate with pale yellow liquid; stimulating and unstable, with light or heat releasing nitrogen dioxide; may be mixed with water in any ratio, and release a lot of heat; nitrate aqueous solution with conductivity; concentrated nitric acid is highly corrosive. Skin contact may cause burns and respiratory mucosa damage.
Four, lifting injury
Lifting damage refers to the damage and loss of equipment caused by equipment failure or personnel operation in the process of using the lifting equipment. The types of lifting damage are lost, falling, and crashes. In the mineral processing plant, the equipment is frequently used, and special attention should be paid to the prevention.
Five, dust hazard
Dust hazard refers to the concentration of solid particles contained in the air is too large, or containing toxic solid particles, inhaled dust production, can cause irritation of the respiratory tract, rhinitis, pharyngitis, bronchitis and upper respiratory tract inflammation, serious can develop pneumoconiosis; at the same time, the production of dust can also cause skin irritation dry skin, folliculitis, pyoderma and other diseases.
Six. Noise injury
Noise is a cause irritability, or the volume too strong and the voice of harm to human health, the noise will cause harm to human health, such as strong noise can cause ear discomfort, such as tinnitus, earache, hearing impairment; the work efficiency is low; cardiovascular damage; noise can also cause such as nervous system disorders endocrine disorders, mental disorders, and even higher accident rate.
Seven, high falling
High work is the operation of the high level of falling height base 2m (including 2m) which may fall. Falling on the high side is a casualty accident caused by falling in high position operation. The main reason is the lack of safety and technical knowledge and the safety facilities for falling down, the imperfection of equipment and the lack of concentration of workers.
The main types are: falling by pedaling material strength is not enough, suddenly fracture height; mobile position, Ta, instability; when working at height, due to improper operation or failure by the mobile station of the collision fall.
Eight. Drowning
Drowning is commonly known as drowning, drowning accident process is very fast, usually 4~5 minutes or 6~7 minutes can be caused by respiratory heartbeat and death.
In addition to the above eight possible hazards in mineral processing, there are other hazards that may exist in raw material transportation, unloading process and driving vehicle.
In all kinds of construction operation, security has been the main problem, there may be more subtle, for small problems, not worth mentioning in our view of the potential of the qianlizhidi, destroyed the colony, to prevent early, will not lead to greater consequences.
