which may cause more serious toxicity due to no obvious symptoms. Avoid splashing such substances on people's eYes, skin and clothing, and wear protective work clothes, protective gloves and protective glasses. When using such substances, make sure that the site is well ventilated, avoid inhaling smoke, steam and spray as much as possible, and keep the container sealed. Do not use in confined spaces. When spraying materials with solvent, such as paint and adhesive, make sure that the site is well ventilated. When the air circulation is not smooth, gas masks should be used. Heating or burning operations may only be carried out under the special guidance of the manufacturer.
1.1.1.1.2.32 Suspension load warning: temporary assembly of lifting equipment is prohibited. Heavy objects are dangerous when lifted or suspended.Do not work under unsupported, suspended or lifted objects, such as suspended motor in one. Ensure that the lifting equipment such as Jack, lift, axle bracket and sling are in good condition and inspected regularly. 1.1.1.1.2.33 Underbody seal Reference: 1.1.1.1.2.12 corrosion protection materials. 1.1.1.1.2.34 Welding Reference: 1.1.1.1.2.17 fire protection, 1.1.1.1.2.15 electric shock, 1.1.1.1.2.22 high pressure cylinder. Welding procedures include spot welding (resistance welding), arc welding and gas welding.
(1) Resistance welding A large number of high-speed molten metal particles will be released during spot welding, so attention must be paid to protect the skin and eYes. (2) arc welding There will be a lot of ultraviolet radiation during arc welding, which will damage the skin and eYes of operators and other nearby personnel.Gas shielded welding is very dangerous, personal protective clothing must be worn and protective screen must be used to protect other people.
When using arc welding, it is suggested that the wearer of contact glasses should return to wearing ordinary glasses.Arc light will release microwave, which makes contact lens wearer's cornea and lens dry due to water loss, and even make people blind.When using arc welding, there will be metal splashing, and proper eye and skin protection measures must be taken. When the welding core or its protective layer is polluted, the heat of the welding arc will make the metal molten pool produce smoke and gas during welding.
These gases may be toxic and should not be inhaled.Toxic gases in the working area must be eliminated, especially when the air circulation is not smooth or when a large amount of welding is known in advance.In special cases or in narrow areas, oxygen masks must be worn. (3) Gas welding (gas cutting) When welding and cutting, oxyacetylene flame will be used for cutting. Special attention should be paid to the leakage of such gas, which may cause combustion and explosion. When using gas welding, metal splashes will be produced, and proper measures must be taken to protect the skin and eYes.Welding flame is very dazzling, so you must protect your eYes.
As the ultraviolet light generated by gas welding is less than that of arc welding, protective glasses can be used. When gas welding is used, some toxic gases will be produced, but this kind of toxic gas is produced by welding coating, especially cutting damaged part.Inhalation of such gases should be avoided. When brazing, the metal in the copper welding rod will produce toxic gas. If there is cadmium in the copper welding rod, it will be very dangerous.When this happens, special care should be taken to avoid inhaling toxic gases and seek the help of experts. No matter what kind of welding or cutting is carried out in the car with inflammables, special 10
