The risk of abnormal oxygen leakage concentration in industrial enterprises
The risk of abnormal oxygen leakage concentration in industrial enterprises
In modern steel companies, the large application and important role of oxygen. Oxygen is an important gas for animals and plants to survive, but if the concentration is too high or too low, it will cause harm to the body. If people inhale high oxygen in a high concentration oxygen environment for a long time, oxygen poisoning will occur; and with the purity of oxygen The increase of the oxidation reaction is intensified, and the oxidation reaction in pure oxygen is extremely intense, and at the same time, a large amount of heat is released, thereby generating high temperature. Therefore, some substances that are not easily combusted in the air are prone to combustion in pure oxygen; and oxygen is mixed with combustible gas (such as natural gas, acetylene, etc.) to form a blasting gas at a certain ratio, once the ignition point or ignition condition is reached. Underneath (such as friction sparks, etc.), there will be serious explosions.
Therefore, the safety management of the oxygen system of steel companies is very important.
1. In places where there are many types of work, there is no possibility to release a large amount of oxygen to the atmosphere.
2. In the place where there are many types of work, if there is a large amount of oxygen leakage accident, it is necessary to immediately notify the downstream workers of the wind direction to stop the operation and evacuate the site. The plant safety management personnel use the oxygen detector to detect the oxygen content. The normal value can only be resumed.
3. If it is necessary to work under oxygen-rich conditions, the operator shall not perform open flame operations such as electric welding, gas welding and gas cutting. Do not use spark-generating tools (ordinary steel wrenches, hammers, etc.). Use a copper alloy material that does not generate sparking tools to prevent sparks from being generated by the tool.
4. Oxygen leaks into the atmosphere in large quantities. If there is a strong wind, the airflow is agitated sharply, the distance of the oxygen mass drifting along the ground is short, the risk of fire is small, and the possibility of burns by nearby people is small; if it encounters a breeze, The airflow diffusion speed is slow, and the distance of the oxygen mass drifting along the ground is long, which causes a high risk of fire, and the possibility of burns by nearby people is also large. Therefore, special attention should be paid to the safety of operations under oxygen leakage conditions in breezy weather conditions.
5. It is forbidden to wear chemical fiber clothes in the workshop environment, because chemical fiber clothes are easy to generate static electricity. You can wear uniforms made of cotton.
6. All parts in contact with oxygen should be kept clean and no grease is allowed to stain.
7. Install an abnormal oxygen concentration alarm device for real-time online detection of oxygen leakage and concentration exceeding the standard in the environment. Once the alarm concentration value set exceeds the standard, it can promptly remind.
In order to strengthen the control of oxygen leakage accidents, reduce the risk of accidents, and ensure the safety of life and property of the company and employees, the iron and steel enterprises should regularly conduct security knowledge training for employees and ensure the installation and installation of security measures and security equipment.
