The first impression that a steel smelting plant gives is that the working environment temperature is high, but that's not entirely true. Why do you say that? Compared to most industrial industries, steel smelters have lower safety factors due to the frequent occurrence of sparks scattering, gas explosions, high-temperature molten liquid splashing or leakage during high-temperature operations. Here are four common hazards of steel smelter operations:
1. High temperature burns - the biggest hazard factor
During iron or steel tapping, the temperature around the furnace wall can reach up to thousands of degrees Celsius. Once the steel drum is overturned or accidentally falls due to operation, it is possible to be burned by molten metal or slag. On the other hand, prolonged operation in front of the blast furnace, coupled with the high temperature season, can easily cause excessive sweating and heat cramps or heatstroke in the human body.
2. Carbon monoxide poisoning
In the process of steel production, a large amount of gas is produced. After dust removal, coal gas can be used as a power fuel or chemical raw material for other production processes. However, the concentration of carbon monoxide in this type of gas is relatively high, generally ranging from 10% to 60%. Once carbon monoxide gas leaks out of the furnace or transportation pipeline, it is extremely easy to cause carbon monoxide poisoning. Carbon monoxide poisoning accidents in steel mills often occur during operations or equipment maintenance around blast furnaces.
3. Smoke and dust
In smelting and sintering operations, a large amount of smoke and high concentration dust are generated in front of the blast furnace and steelmaking furnace. The dust with a higher content in smoke is composed of silicon dust. If inhaled for a long time, it is easy to form silicosis and increase the probability of pneumoconiosis.
4. Mechanical injury
Mechanical injuries often occur during steel transportation, and some large steel plants do not use manual transportation but instead use specialized locomotives and tracks. Once equipment malfunction or personnel negligence occurs, it may cause serious mechanical injury or death.
In response to the four common hazards mentioned above, the corresponding job safety protection measures are as follows:
1. High temperature burns are mainly aimed at protecting the entire body. It is recommended that operators in front of the furnace wear high-temperature insulation clothing (including high-temperature boot covers, high-temperature masks, and high-temperature gloves). The selection of high-temperature insulation suits should be defined based on the temperature of the on-site working environment. For example, if the ambient temperature is around 700 degrees Celsius, it is recommended to purchase high-temperature insulation suits with a resistance temperature of 1000 degrees Celsius. In addition, during hot summer work, considering the poor breathability of wearing high-temperature insulation clothing and the high temperature inside the insulation clothing, it can be used together with a cooling vest to reduce body temperature to a certain extent, making it more comfortable.
2. To prevent carbon monoxide poisoning, the following two aspects can be considered: first, regularly check the airtightness of the equipment, and intelligent devices with conditions can also be equipped with alarms, paying attention to natural ventilation; The second is to equip the job position with carbon monoxide gas masks, and try to ensure that each person has one. When starting the furnace operation, if it is necessary to follow the rules and procedures, wear the carbon monoxide gas mask before proceeding to the next step.
3. Dust protection, this is mainly aimed at respiratory protection. While improving the working environment, industrial dust masks or dust masks can be worn. When selecting dust masks, attention should be paid to the filtration efficiency of dust particles, and the products to be selected must be qualified products certified by the National LA.
4. Mechanical injury is much smaller than the other three types of hazards. The most important thing about mechanical injury is to regularly maintain and inspect the equipment. In addition, if some special processes require manual handling, personnel should try to wear safety shoes when working.
